[Maria-discuss] INSERT IGNORE (and other SQL commands) fail with: Deadlock found when trying to get lock;
by Benoit Panizzon 14 Dec '13

14 Dec '13

Hello We have migrated a mailserver project from MySQL NDBCluster to MariaDB Gallera Cluster because we often had sync problems with NDBCluster. Now we found that various of our tools and also our SOAP API Server do not work anymore because some SQL Statements that used to work on NDBCluster do not work with Gallera anymore. I wonder if we stumbled over bugs or if this is some kind of expected behaviour and if yes, how to work around them. We run the most actual version: 5.5.33a Some examples: We have a skript, that from time to time wants to completely delete some statistics data. We don't know if there is already data in that table, we just want to get rid of it... Just some examples how to reproduce the problem: === DELETE on EMPTY TABLE === MariaDB [maildb]> create table statistics (id int(11) primary key, data varchar(30)); Query OK, 0 rows affected (0.80 sec) MariaDB [maildb]> insert into statistics set id=1,data="FooBar"; Query OK, 1 row affected (0.04 sec) MariaDB [maildb]> delete from statistics; Query OK, 1 row affected (0.26 sec) MariaDB [maildb]> delete from statistics; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction Why the heck do we get a severe error when deleting data from an empty table. This causes the perl skipt to die and not continue it's execution. === INSERT IGNORE === We merge information about users from two sources. One source contains the password. One source might contain additional user which were not added from the first source, but do not contain the passwort. But they also contain users already inserted from the first source, so if a unique key exists, it must not be overwroten. Therefore we can not use REPLACE INTO but would use INSERT IGNORE: MariaDB [maildb]> show create table user\G *************************** 1. row *************************** Table: user Create Table: CREATE TABLE `user` ( `id` int(11) NOT NULL AUTO_INCREMENT, `userid` varchar(30) DEFAULT NULL, `passwd` varchar(30) DEFAULT NULL, `domain` varchar(30) DEFAULT NULL, `homeserver` varchar(30) DEFAULT NULL, `quotaInMiB` int(11) DEFAULT '100', `password_type` varchar(10) DEFAULT 'plain', `spamaction` enum('REJECT','ACCEPT','TAGGING') DEFAULT 'REJECT', `spampoint` decimal(5,1) DEFAULT '5.2', `virusaction` enum('REJECT','ACCEPT','REPLACE') DEFAULT 'REJECT', `keepFwdCopy` tinyint(1) DEFAULT '0', `quotaUsed` int(11) DEFAULT '0', `extRef` varchar(12) DEFAULT NULL, `mandate` int(11) DEFAULT '0', `FwdBounceCount` decimal(1,0) DEFAULT '0', `FwdActive` tinyint(1) DEFAULT '0', `lastActive` datetime DEFAULT '0000-00-00 00:00:00', `lastLogin` datetime DEFAULT '0000-00-00 00:00:00', `disabled` tinyint(1) DEFAULT '0', PRIMARY KEY (`id`), UNIQUE KEY `userid` (`userid`,`domain`) ) ENGINE=InnoDB AUTO_INCREMENT=1808 DEFAULT CHARSET=utf8 First Source: MariaDB [maildb]> insert into user set userid="dummyuser",domain="example.com",passwd="verysecret"; Query OK, 1 row affected (0.00 sec) Second Source: Now we get a user that does not already exist, but for which we do not have a password: MariaDB [maildb]> INSERT IGNORE user set userid="otheruser",domain="example.com",passwd="random1"; Query OK, 1 row affected (0.00 sec) Now that second source provides another user, which already exists in the database, so we do want to ignore that insert: MariaDB [maildb]> INSERT IGNORE user set userid="dummyuser",domain="example.com",passwd="otherrandom1"; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction What happened there? In NDBCluster this works perfectly. Gallera fails, that merge skipt stopps. Google suggested replacing INSERT IGNORE by ON DUPLICATE KEY update id=id to just do a dummy update, but that fails too: MariaDB [maildb]> INSERT user set userid="dummyuser",domain="example.com",passwd="otherrandom1" ON DUPLICATE KEY UPDATE id=id; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction Any suggestions?

Hi! MySQL 5.6 returns a warning for wrong datatypes, with any SQL_MODE: mysql> CREATE TABLE t (c TIMESTAMP) ENGINE=InnoDB; Query OK, 0 rows affected (0,31 sec) mysql> SELECT c FROM t WHERE c = 1; Empty set, 1 warning (0,00 sec) Warning (Code 1292): Incorrect datetime value: '1' for column 'c' at row 1 Will this be done in MariaDB 10 too? Currently, no warning is issued. Federico

[Maria-discuss] INFORMATION_SCHEMA.PROCESSLIST values of PROGRESS, STAGE and STAGE_MAX
by Jean Weisbuch 11 Dec '13

11 Dec '13

Hello, Lately, i did modify mytop (https://mariadb.atlassian.net/browse/MDEV-4476) to use INFORMATION_SCHEMA.PROCESSLIST instead of SHOW PROCESSLIST (when available) to gather running processes informations as it's more flexible and has more informations but the value of the PROGRESS column on both is different, so i wondered if the PROGRESS value on SHOW PROCESSLIST was using a simple formula like this one or something more complex : (STAGE-1)/MAX_STAGE + {decimal progress on the actual stage}/MAX_STAGE There seems to be a broken alinea about that on the KB page of the PROCESSLIST : https://mariadb.com/kb/en/show-processlist/ In any case, what would be the best way to go with mytop, add columns with the actual_stage/max_stage or only keep the progress of the actual stage or only the "total" progress using the formula previously shown? Putting an option and keystroke to show/hide these columns could be another solution as these values might be of use on only "rare" cases depending on the workload. Regards.

[Maria-discuss] Mroonga storage engine is merged into MariaDB 10.0
by kentoku 01 Dec '13

01 Dec '13

Hi! We just pushed Mroonga storage engine into "lp:~mroonga/maria/mroonga". Mroonga is a fulltext/geo search storage engine. Would you please bundle Mroonga into MariaDB? Mroonga's strong points are - High-speed updating with multiple thread searching. (lock-free model) - Support CJK languages. - Support wrapper mode. Wrapper mode works adding fulltext/geo index for other storage engines. Mroonga is tested on the following 64bit OS. Debian GNU/Linux squeeze Debian GNU/Linux wheezy Debian GNU/Linux jessie Debian GNU/Linux sid Ubuntu 10.04 LTS Lucid Lynx Ubuntu 12.04 Precise Pangolin Ubuntu 12.10 Quantal Quetzal Ubuntu 13.04 Raring Ringtail Ubuntu 13.10 Saucy Salamander CentOS 5 CentOS 6 Fedora 19 Mac OS X Windows 7 Mroonga documents (English & Japanease) are available on http://mroonga.org/docs/index.html Test command is the followings. The command calls mysql-test-run.plinternally. > ./storage/mroonga/test/run-sql-test.sh Thanks, Kentoku

[Maria-discuss] New Question: Mariadb refuses to stay confined to install directory
by AskMonty KB 29 Nov '13

29 Nov '13

Hello, A new question has been asked in "Compiling MariaDB From Source" by openiduser33: -------------------------------- I've been struggling with this off and on for weeks. I need a contained MariaDB install running in the home directory. My most recent attempt (and what would be my preferred method) is compiling from source. No matter what I do though MariaDB insists on trying to create /var/run/mysqld/mysqld.sock on every run and fails. I compiled it from source with --prefix pointing to my home directory. I ran mysql with --basedir and --defaults-file. The defaults-file I used contains the location of my mysql.sock file in the home directory but MariaDB will not use it. I even tried recompiling with --exec-prefix as per the MySQL 5.5 documentation but this screws the entire installation up, causing MariaDB to recreate the entire prefix path from root underneath src/efix=/ where I'm storing the source while I install. Here is my configure options: ##./configure --prefix=/home/user/web/servers/mariadb --enable-assembler \ --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables \ --with-plugin-maria --with-aria-tmp-tables --without-plugin-innodb_plugin --without-plugin=tokudb \ --with-mysqld-ldflags=-static --with-client-ldflags=-static --with-readline \ --with-ssl --with-plugins=max-no-ndb --with-embedded-server --with-libevent \ --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static \ --with-zlib-dir=bundled --enable-local-infile## And here is what happens when I try to launch MariaDB: ##$ bin/mysqld_safe --basedir=/home/user/web/servers/mariadb --defaults-file=/home/user/web/servers/mariadb/my.cnf 131128 16:20:20 mysqld_safe Logging to '/home/user/web/servers/mariadb/log/error.log'. mkdir: cannot create directory ‘/var/run/mysqld’: Permission denied Fatal error Can't create database directory '/var/run/mysqld/mysqld.sock'## My socket file is specific in the given my.cnf file as /home/user/web/servers/mariadb/run/mysql.sock No matter what I do I can't get MariaDB to behave and run in user land. What am I doing wrong? I've tried the Linux binaries with slightly more success but I still felt like I was fighting the server to get it to read files from the correct location. I'd like to have it compiled from source though and it *should* be easier this way since I can specify a prefix. How can I get MariaDB to follow the set prefix for all files? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-refuses-to-stay-confined-to-install-direct…

[Maria-discuss] Table Change notification to all Clients?
by SARTrack Admin 21 Nov '13

21 Nov '13

I develop a Windows application for Search and Rescue (using Delphi and MyDAC components), which gets a stream of "APRS" data packets, up to 10 per second. These are saved in the SQL database, but all Clients which are connected to the database MUST be notified when a Table change has occured, so that they then can update their internal tables. Which in turn update their Maps (GPS location of moving items) and other data, which MUST be up-to-date. Currently I am having all Clients polling the database every 5 seconds, which really sucks, and causes all kinds of other problems. Is there any chance that MariaDB will have some kind of Client Notification system when a Table has changed, as some other SQL databases seem to have? Thanks Bart Kindt SARTrack Limited http://www.sartrack.co.nz/ -- SARTrack Developer and CEO

[Maria-discuss] Is OQGRAPH back in 10.0.5?
by Colin Charles 11 Nov '13

Hi! I noticed that ha_oqgraph.so exists in /usr/lib64/mysql/plugin on the 10.0.5 packages. So I just installed it, and it shows up in SHOW ENGINES output. I tried creating a table, and it worked (confirmed via output in SHOW TABLE STATUS) So, is this something we are planning on shipping in 10.0? This is version 2 of the plugin and it is now marked to be Beta quality (from INFORMATION_SCHEMA.PLUGINS) If we are shipping this in 10.0, we really need to improve the documentation around it in the Knowledgebase cheers, -colin -- Colin Charles, Chief Evangelist MariaDB | t: +6-012-204-3201 | Skype: colincharles

[Maria-discuss] New Question: mariadb RAM usage
by AskMonty KB 08 Nov '13

08 Nov '13

Hello, A new question has been asked in "MariaDB Performance & Advanced Configurations" by ferreirah: -------------------------------- When you bundle your app with mysql or mariadb, you don't want mysql or mariadb to devour all your RAM, especially if the database is installed on a desktop operating system. I haven't recently tried out mysql or mariadb, but I was wondering about the minimum memory required on windows. I sent a question to mysql and they told me it only requires 1 MB RAM minimum. At that stage they still supported windows 2000 and windows xp, which isn't supported any more. I remember installing mysql on windows xp and you could configure it through a wizard. You could either set it to dedicated server, shared server or developer install. I suppose developer install will use the least amount of RAM. How much RAM would mariadb use with a developer install if you had to install it on windows vista/7/8/8.1? Does it matter which engine you are using? XtraDB?

[Maria-discuss] New Question: licencing of mariadb and mysql dot net connector
by AskMonty KB 08 Nov '13

08 Nov '13

Hello, A new question has been asked in "Client libraries" by ferreirah: -------------------------------- Hi I agree with one of the previous posts that licencing is such a tricky aspect of IT. I read in previous posts that when using mariadb with the odbc framework that you can distribute both the odbc connector and mariadb with your closed source commercial application. It said in the post if you use a framework to access the database then both the connector and mariadb are free for commercial use. What about dot net? Dot net is a framework through which you can access mariadb? Does this mean that both the dot net connector as well as mariadb are free for closed source commercial use? I suppose the downside is that you can't use any mariadb specific features if you are using the mysql connector?

[Maria-discuss] Problem when all galera nodes are down
by Guillaume Hilt 29 Oct '13

29 Oct '13

Hi again, We're running 3 galera mariadb 5.5 servers on Ubuntu 12.04 AMD 64 server. With one drbd server on another host. We have a specific case in our dev environment. All the hosts are stopped at night. So when they all boot up at the same time in the morning, each server is looking for another one up. Since there are no other server up, they refuse to start. I have to edit the wsrep_cluster_address variable on one server to set it back to "gcomm://" and start it. Then start the 2 others servers and once everything is up, put back the wsrep_cluster_address variable to its previous value and restart the server. Galera isn't prepared having all its nodes down ? Thanks, -- Guillaume Hilt

[Maria-discuss] MariaDB 10 compatibility with MySQL

29 Oct '13

Picked from the debian-mysql discussion list: > Separately has your company considered MariaDB 10.0? Once we get the 5.5 line uploaded I'd like to package 10.0. Providing 10.0 is also compatible with MySQL and wouldn't require any apps to be updated I'm sure we could consider it. I would have difficulty getting developer resources to modify existing apps though. I think the above is very important to always remember for real world users... -- Colin Charles, Chief Evangelist MariaDB | t: +6-012-204-3201 | Skype: colincharles

[Maria-discuss] Synchronization down after reboot
by Guillaume Hilt 25 Oct '13

25 Oct '13

Hello, I'm using MariaDB with Galera replication on 3 Ubuntu 12.04 servers : Server version: 5.5.33a-MariaDB-1~precise mariadb.org binary distribution, wsrep_23.7.6.rXXXX They're all development servers, in the same local network, so there's no firewall between them. They were all working fine until a reboot. Now node 2 and 3 aren't in sync anymore and mysql refuse to start. Replication is done using xtrabackup. I can start over by doing a mysqlhotcopy on node1 and put the data on node2 and node3 but i'd like to understand why it didn't survived a reboot. Here's my nodes : * Node 1 : dev-sql-001 / 192.168.3.121 * Node 2 : dev-sql-002 / 192.168.3.221 * Node 3 : dev-sql-003 / 192.168.3.222 Here's the log on node 1 when I try to start node 2 : Oct 22 10:19:29 dev-sql-001 mysqld: 131022 10:19:29 [Note] WSREP: declaring abbffcb5-3af2-11e3-a043-5b38dfb689cf stable Oct 22 10:19:29 dev-sql-001 mysqld: 131022 10:19:29 [Note] WSREP: Node f743192f-3aee-11e3-a47b-97626a725dde state prim Oct 22 10:19:29 dev-sql-001 mysqld: 131022 10:19:29 [Note] WSREP: view(view_id(PRIM,abbffcb5-3af2-11e3-a043-5b38dfb689cf,6) memb { Oct 22 10:19:29 dev-sql-001 mysqld: #011abbffcb5-3af2-11e3-a043-5b38dfb689cf, Oct 22 10:19:29 dev-sql-001 mysqld: #011f743192f-3aee-11e3-a47b-97626a725dde, Oct 22 10:19:29 dev-sql-001 mysqld: } joined { Oct 22 10:19:29 dev-sql-001 mysqld: } left { Oct 22 10:19:29 dev-sql-001 mysqld: } partitioned { Oct 22 10:19:29 dev-sql-001 mysqld: }) Oct 22 10:19:29 dev-sql-001 mysqld: 131022 10:19:29 [Note] WSREP: New COMPONENT: primary = yes, bootstrap = no, my_idx = 1, memb_num = 2 Oct 22 10:19:29 dev-sql-001 mysqld: 131022 10:19:29 [Note] WSREP: STATE EXCHANGE: Waiting for state UUID.

[Maria-discuss] Parallel build support for v10?
by jen142＠promessage.com 24 Oct '13

24 Oct '13

Hi, I build MariaDB v10 from src on linux/64. If, after `cmake` configure I attempt a parallel build, make -j4 VERBOSE=1 I get numerous/sequential build failures. ALL of the related failures vanish if I simple single-thread the build, make -j1 VERBOSE=1 *IS* MarbiDB v10 currently intended to be parallel-buildable? jen

[Maria-discuss] How to disable TokuDB libtokuportability.so check in 10.0.4/r3863 source build?
by jen142＠promessage.com 24 Oct '13

24 Oct '13

I'm building v10.0.4/r3863 on opensuse/64. This latest-version build newly fails @ cd /usr/local/src/mariadb/bld/storage/tokudb/ft-index/ft && ./logformat . ./logformat: error while loading shared libraries: libtokuportability.so: cannot open shared object file: No such file or directory This is changed behavior. I'm currently not interested in TokuDB. Reading @ https://mariadb.com/kb/en/how-to-enable-tokudb-in-mariadb/#enabling-tokudb it's not supported on my platform anyway. There's info on how to ENABLE it, but not how to DISABLE it -- so the build doesn't complain. How do I correctly DISABLE it in my build? Jen

[Maria-discuss] maria certifications?
by Federico Razzoli 24 Oct '13

24 Oct '13

I found a site about MariaDB certifications: http://www.mariadbcertification.org/ However, it looks like a sort of work in progress. Also, I don't understand if it is something official, or at least recommended by the Foundation. And, if it is not, is any official certification planned? Ciao Federico

[Maria-discuss] New Question: Using Connect with MySQL 5.5
by AskMonty KB 23 Oct '13

23 Oct '13

Hello, A new question has been asked in "Connect" by shlomisut: -------------------------------- Hi We're currently testing usage of MySQL Federated engine, used for read-only cached tables. The Connect engine looks like a very interesting option as it will allow us to use the index/condition push down, thus reducing the amount of network & total query time. Do you have any experience with using Connect as a MySQL engine? migrating to MariaDB is not possible at current time frames, though it is on our roadmap Thanks!

[Maria-discuss] Binlog replication protocol in MySql 5.0.95, 5.1 and 5.5
by Vesa-Matti J Kari 21 Oct '13

21 Oct '13

Hello, We have a MySQL Version 5.0.95 setup that consists of 1 master server and 3 replication slave servers. Now we want to upgrade these servers to MySQL 5.5 via intermediate step MySQL 5.1. Can we upgrade one MySQL server at a time or do we have to take all servers down and upgrade all at once? In other words, is the binlog replication protocol compatible between all MySQL 5.0.95, 5.1 ja 5.5? Many thanks for the information. Regards, vmk -- ************************************************************************ Tietotekniikkakeskus / Helsingin yliopisto IT department / University of Helsinki ************************************************************************

18 Oct '13

Hello, A new question has been asked in "MariaDB Client Library for C" by gghervase: -------------------------------- Hello, Can you please tell me if a new stable release for the mariadb native client will be done anytime soon? There are several bug fixes on trunk and I wonder when will they be released. For example, I can't ssl authenticate to the maridb 5.5.33 with the currently released client (Bad Handshake - response error 1043 from the server), but it works with your lastest code from trunk. Thank you very much.

[Maria-discuss] DELETE Operations in MariaDB 5.5.30 do not reduce size of table files
by Steve Afrin 09 Oct '13

09 Oct '13

To anyone who knows how the MyISAM engine works (or maybe this is independent of the DB engine), here’s my scenario: * I have a table with 180,000 rows * I delete 170,000 rows with a DELETE and subsequent COMMIT statement * The MYI table file is still the same size it was before the 170k rows were deleted I saw there’s an administrative PURGE command, but it looks like that is just for purging data from binary logs, if you’ve even turned on the option for keeping binary logs. In MariaDB 5.5.30 or later, how do I run a purge operation to compress the deleted rows of data out of my physical table files and cause the reindexing to happen for the data that is still in my tables? Thanks, Steve

[Maria-discuss] New Question: regarding seconds behind master variable in 10.0.4
by AskMonty KB 09 Oct '13

09 Oct '13

Hello, A new question has been asked in "MariaDB Documentation" by jaihind213: -------------------------------- hi we setup maria 10.0.4 for multisource replication. it was replicating from a percona 5.5 master. When we started replication, maria was a day behind its master. its working fine but we noticed this phenomenon: when we execute 'show all slaves status' consecutively the 'seconds_behind_master' flips from 0 to XXX and XXX to 0. XXX keeps decreasing though, which is good as its getting closer to the state of its master. But wanted to know why the 'seconds_behind_master' comes down to 0 then again sets to a positive number. Note: XXX is some positive number.

Hi Folks, I'm seeing a difference in a query result between MariaDB 5.5.32 and MySQL 5.1.69. I've distilled things down as far as I can get them, while still being able to reproduce the issue. Anything else I do to get the sample to make it smaller or more focused seems to make the issue disappear.

[Maria-discuss] New Question: Migrating from MySQL 5.1.31-community >> MariaDB 5.5
by AskMonty KB 03 Oct '13

03 Oct '13

Hello, A new question has been asked in "Upgrading MariaDB" by flumpydog: -------------------------------- One of our internal development db servers is currently running MySQL 5.1.31-community on CentOS 5.9 as it suits are needs internally for testing only purposes of our sites. I would like to use this box to install and test MariaDB 5.5 on. What would be the best method to make this transition as smooth as possible? The MySQL rpm's are not the ones supplied by CentOS, but are from the MySQL site. Should I do a dump of all the databases on MySQL, remove all the MySQL rpm packages, install MariaDB 5.5 via yum and then do an import of the databases? Or will I have to install a prior release of MariaDB and upgrade from there? Also, all the tables are currently using the MyISAM storage engine. Just so I will have the best experience here and while I am experimenting, what storage engine would you recommend we try, Ari or? Some of these tables contain in excess of a million rows. Is there anything I should be aware of before converting tables?

[Maria-discuss] The MariaDB Foundation and MariaDB trademark?
by Jeremy Cole 02 Oct '13

02 Oct '13

While poking around on the various sites (discussed at length in previous threads) I was left wondering about the MariaDB trademark. I was under the impression this was going to be owned by and managed by the MariaDB Foundation. It seems like it was registered by Monty Program Ab though, and never transferred to or owned by MariaDB Foundation. So, after the acquisition it is now owned by SkySQL. The SkySQL site's "Trademarks" page<http://www.skysql.com/about/legal/trademarks>definitively confirms this with the text «The "MariaDB" trademark is wholly owned by SkySQL Corporation Ab and is a registered trademark in ...». So, I am left wondering what happened? Was my original understanding incorrect, or was this never properly followed through? While I would hope SkySQL is a good community member and would not do anything bad with the trademark, this does defeat a lot of the original idea with the foundation, by my understanding, and leaves a single commercial entity in more or less full control of MariaDB's future. Can anyone provide some insight? Regards, Jeremy

(this thread was originaly from maria-developpers) The mariadb.com/.org distinction is not really clear as both have a similar layout, designs and duplicate contents, plus distincting both sites from the sole TLD is not the most visible one ; i must admit that the first time i ended up on mariadb.com i thought at first that it was just the mariadb.org website that had a design update. Plus, there is a link to "mariadb.org" on the top menu of mariadb.com, a link to "Community" or "MariaDB Foundation" or a clear title would be better.

I think the 'mysql' client with MariaDB has a similar problem as it has with MySQL - refer? http://bugs.mysql.com/bug.php?id=70443 MariaDB installer installs my.ini to /datadir - what with MariaDB is a subfolder to /basedir. The server will look for it correctly as the registry key defining the service has a --default-file specification. But the command line clients don't read the registry key. @Wlad? -- Peter -- Webyog

[Maria-discuss] multi master and conflicts
by Roberto Spadim 26 Sep '13

26 Sep '13

Hi guys, New problems to solve here =) if anyone could help should be nice :) I have an old system that use only one server with aria/myisam tables (some temporary tables and some views too) I want to implement a multi master replication (near to a cluster...), but i should take care about replication conflicts.... There's some good pratices or books about implementing multi master without replication conflicts? Should I change it to galera cluster? Well maybe.. I don't know what to do with aria storage, galera works with innodb/xtradb/myisam, what about aria? i didn't tested yet I don't know what to do about commit phase with myisam too, since galera do the certificate at commits phase before commit, and myisam problably do a autocommit at each insert/update/delete, this will be a problem, or not? The idea is not use innodb or I should implement some tables or views to have a faster COUNT/MIN/MAX functions (myisam is optimized for it), and i should rewrite some codes to use BEGIN, COMMIT, and cancel if connection is lost Well physical problems... Servers will not be online all time, the network link isn't good, servers are ~50km far via a wifi link with some tree and birds and others problems (that's why i think async replication is ok, instead of galera 'sync' cluster) Any idea is well come, but should be nice something that myisam/aria could be used I asked some days ago about replication and galera and xtradb cluster, but i'm not sure what to do yet tks guys! ideas are wellcome -- Roberto Spadim

[Maria-discuss] 'Converting' a myisam to multi-master
by Roberto Spadim 20 Sep '13

20 Sep '13

Hi guys, there's one easy way to implement a multi-master cluster using myisam/aria ? i know that galera cluster use innodb as backend, there's anything similar to aria/myisam? scaledb? ndb? others? the main problem switching from aria/myisam to innodb is the MIN/MAX/COUNT(*) optimization and the rows sizes/index considerations ( https://mariadb.com/kb/en/converting-tables-from-myisam-to-innodb/) and since it's myisam/aria many apps don't use begin transaction / commit (maybe this is a problem for cluster/multi master?) thanks guys :) -- Roberto Spadim

Hello, A new question has been asked in "General FAQ" by vivek_kubaji: -------------------------------- We in the process of migrating from MySql to MariaDB due to licensing/commercial usage reasons. We have successfully replaced the MySql connector jar with MariaDB client jar (first change) and are now trying to replace MySql server with MariaDB server without changing the data files.

I initially suspected of idle connections but we are using Hibernate configurations like 'testOnBorrow' so it shouldn't be the case. Can anyone help us to find out the cause for this and help us fix the problem? Is there any specific configuration in MariaDB that I should be doing? I've even run our applications by increasing the value of the param 'interactive_timeout' in the MariaDB server but it did not help. Btw, we are using Spring-Hibernate and pooling our connections using Commons-pool jar. Any kind of help will be deeply appreciated.

[Maria-discuss] New Question: How to install MariaDB rpms in CentOS 6.4 using rpm (not yum cmd) + handling mysql-libs conflicts
by AskMonty KB 14 Sep '13

14 Sep '13

Hello, A new question has been asked in "MariaDB community" by theone: -------------------------------- I need to script the install of MariaDB using the rpm command in CentOS 6.4. I can't use yum since it's gong to be an offline install so there's no live access to the repository. The only MySQL package installed is mysql-libs as various other packages depend on it. When I did a test install of MariaDB with yum using the command: yum install MariaDB-client MariaDB-common MariaDB-compat MariaDB-devel MariaDB-server MariaDB-shared It correctly accounted for mysql-libs and uninstalled it at the end as MariaDB could handle the dependencies after it was installed: Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package MariaDB-client.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-common.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-compat.x86_64 0:5.5.32-1 will be obsoleting ---> Package MariaDB-devel.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-server.x86_64 0:5.5.32-1 will be installed ---> Package MariaDB-shared.x86_64 0:5.5.32-1 will be obsoleting ---> Package mysql-libs.x86_64 0:5.1.66-2.el6_3 will be obsoleted --> Finished Dependency Resolution Dependencies Resolved ==================================================================================================================================================================== Package Arch Version Repository Size ==================================================================================================================================================================== Installing: MariaDB-client x86_64 5.5.32-1 mariadb 10 M MariaDB-common x86_64 5.5.32-1 mariadb 23 k MariaDB-compat x86_64 5.5.32-1 mariadb 2.7 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 MariaDB-devel x86_64 5.5.32-1 mariadb 5.6 M MariaDB-server x86_64 5.5.32-1 mariadb 34 M MariaDB-shared x86_64 5.5.32-1 mariadb 1.1 M replacing mysql-libs.x86_64 5.1.66-2.el6_3 Transaction Summary My question is, what is the equivalent way to install the MariaDB packages using the rpm command only as opposed to yum? If I do rpm -ivh MariaDB*.rpm, I will get a ton of messages like the following about conflicts with mysql-libs: file /etc/my.cnf from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 file /usr/share/mysql/charsets/Index.xml from install of MariaDB-common-5.5.32-1.x86_64 conflicts with file from package mysql-libs-5.1.66-2.el6_3.x86_64 I used the --force option to install and then uninstalled mysql-libs and didn't get any weird messages but I'm not sure that is the cleanest method to handle the conflicts. So can someone confirm that installing MariaDB with the following rpm commands would be the same as using yum to install the packages and handle mysql-libs conflicts/removal: rpm -ivh --force MariaDB*.rpm rpm -e mysql-libs Thanks for any input! -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/how-to-install-mariadb-rpms-in-centos-64-using-rpm…

[Maria-discuss] New Question: Replication stops after one hour or so
by AskMonty KB 11 Sep '13

11 Sep '13

Hello, A new question has been asked in "Replication" by Martin22: -------------------------------- Hi there, we operate a big MariaDB-server (24 CPUs, 48 GB RAM, Version 5.5.32 with Percona XTRADB). Because it is mission-critical it is replicated to another server of similar size (row based replication). We get the ball rolling with "innobackupex" (GREAT tool to clone a life server). After setting the slave to its coordinates it starts up, catches up to the master (times behind = 0) and all is well. For an hour. Or four. Or two days. Then the slave suddenly stops executing the masters binlog. There are no errors logged. I checked the binlog and relaylog on master and slave around the last log entry processed and can't find anything strange. I'm at a total loss. I can't say that I'm an MySQL or MariaDB specialist, so I'd like to reach out to this community in order to get some idea what's happening. Anybody got an idea? Thanks in advance!

(maybe not a problem...) *Please answer the BOLD questions* We are talking about CREATE PROCEDURE , about DETERMINISTIC / NO SQL http://dev.mysql.com/doc/refman/5.6/en/create-procedure.html *characteristic*: COMMENT '*string*' | LANGUAGE SQL | *[NOT] DETERMINISTIC* | { CONTAINS SQL | *NO SQL* | READS SQL DATA | MODIFIES SQL DATA } | SQL SECURITY { DEFINER | INVOKER } *--------* *from mariadb-discuss:* *--------* Hi Federico, sorry i read some points and start writing, i will read and write after... i will answer with my experience as an user, not as a mariadb/mysql developer... 2013/9/2 Federico Razzoli <federico_raz(a)yahoo.it> > Hi Roberto > I'll try to be more clear, please read carefully before answering > ok I know what a deterministic expression is - but *what kinds of output must > be deterministic for a procedure to be defined as DETERMINISTIC?* > hummm i don't know, but for procedure, there isn't a deterministic output right? just for funcitons... maybe it's a parser problem, allow deterministic keyword for procedures (must check) i'm thinking about, *why we use deterministic procs, and non deterministic procs?* *this change something important in mysql server? replication, query cache? other performace considerations?* > There are many types of output for a proc: > * OUT params > * SELECTs > * writes on tables > * SET @var > hum.... from what i remember procedure ~= function without return, something like a "void FUNCTION( any parameters )" function ~= a procedure that return values, in other words it must be different from void... that's why i think it's a problem at parser allowing deterministic keyword at procedure, but must check... i don't know if this keyword change something in mysql/mariadb code > For a deterministic proc, do all of these need to be deterministic? > well, for me, procs are always non deterministics since it don't change query cache invalidation and replication (must be done in binary i think) > * I guess the answer isn't easy. > * *yeah, i see, we need a simple answer not a simplified answer* > -- > For "NO SQL" a complete list of SQL statements would be needed. If we use > this as a reference: > http://dev.mysql.com/doc/refman/5.6/en/sql-syntax.html > , even RETURN seems to be a SQL statement, yes, maybe the point isn't the SQL statements list, but other functions that mysql/mariadb server do? i don't know... NO SQL maybe is different from NOSQL (memcache,mongo,etc...) since nosql is newer than mysql procedures the point is *what's NO SQL in CREATE PROCEDURE ?* but of course it can't be true, because it's impossible to write a func > without RETURN. > yeah, maybe we have a problem at docs... let's see if anyone else know about this... maybe we need help from mariadb-devel list, i will include in this email... > > Greetings > Federico > bye =) thanks guys -- Roberto Spadim

[Maria-discuss] The KB has moved to mariadb.com
by Daniel Bartholomew 02 Sep '13

02 Sep '13

Many people have expressed to me and others working on MariaDB that it would make the most sense for the KB to be located under a MariaDB domain, so I'm happy to report that the KB is now at https://mariadb.com/kb If you've used the KB in the last couple of days, you've probably already noticed this as the change went live over the weekend. We've also updated the colors to match the new look of mariadb.com. We're working on a complete visual refresh to integrate it completely into the look and feel of the new site. But that will come later. For now it's the same KB with slightly different colors under a new domain. All https://kb.askmonty.org/... links should redirect automatically to the correct spot on the new site. Please let me know ASAP via email, IRC, Twitter, G+, or even carrier pigeon if anything isn't working.

[Maria-discuss] New Question: MariaDB on AIX: am I the first to try to compile?
by AskMonty KB 26 Aug '13

26 Aug '13

Hello, A new question has been asked in "Development" by mamfelt: -------------------------------- Since the current owner of mysql is no longer interested in creating/distributing for and IBM platforms - and, as a joomla user I am accustomed to using mysql as backend I am hoping to package and use mariadb on AIX. So, anyone else who has any (successful) experience with compiling mariadb for/on AIX? If yes, what OS level did you use, and compiler? I am trying with OS 5.3TL7 and AIX 6.1TL7. I will prefer to have it work on AIX 5.3 as that should support AIX 6.1 - but at this point I am just looking for a better starting point. Thanks for reply/comments! -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/mariadb-on-aix-am-i-the-first-to-try-to-compile/

[Maria-discuss] New Question: Hibernate Reverse Engineering wizard with MariaDB
by AskMonty KB 22 Aug '13

22 Aug '13

Hello, A new question has been asked in "MariaDB Documentation" by JohnD: -------------------------------- (Sorry, couldn't find a good place for this query - perhaps there ought to be a folder "MariaDB and ORMs"?) I'm trying to use the Hibernate Reverse Engineering wizard with MariaDB. It's just a very simple example, but I am stuck. I don't see any errors, but it doesn't work as described. Here's what I've got so far: * Windows 7 x64, Eclipse Juno, MariaDB v5.5.3, Hibernate v4.2.3 * I've got an example with Hibernate running using annotations and the same instance of MariaDB, no problem * Now I want to create the classes from the tables, so I'm trying to use the reverse engineering wizard. * I've set up a simple DB and a couple of tables * I've set up a hibernate.cfg.xml file using the same values as my working annotation example * Now I use the wizard (in Eclipse) to "New/Hibernate Reverse Engineering File (reveng.xml)" ** First page ok, second page "Configure Table filters" is where I'm stuck ** I select the correct Console configuration (generated as part of creating the config file) and then press the "Refresh" button ** At this point I should see my two tables in the "Database schema:" column. But it's empty. ** I briefly see "Pending..." - then nothing. ** I can't see any errors. So, how to move forwards? Can I turn on some logging? Where is the error? What logs to check? The Eclipse console window shows a bunch of stuff, all info, no errors and the last three lines are like this: * 2013-08-22 11:34:38,189 DEBUG Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - opening new JDBC connection * 2013-08-22 11:34:38,198 DEBUG Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - created connection to: jdbc:mysql://localhost:3306/omthibernate, Isolation Level: 4 * 2013-08-22 11:34:38,199 INFO Worker-33 org.hibernate.connection.DriverManagerConnectionProvider - cleaning up connection pool: jdbc:mysql://localhost:3306/omthibernate In case it helps, here is the hibernate config (I've tried a lot of variations): {{{ <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory name="xxx"> <property name="hibernate.connection.driver_class">org.mariadb.jdbc.Driver</property> <property name="hibernate.connection.password">password</property> <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/omthibernate</property> <property name="hibernate.connection.username">user</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property> </session-factory> </hibernate-configuration> }}} -------------------------------- To view or answer this question please visit: http://kb.askmonty.org/en/hibernate-reverse-engineering-wizard-with-mariadb/

[Maria-discuss] More secure Kill command
by Roberto Spadim 21 Aug '13

21 Aug '13

hi guys, i hit a problem in this exact second... some programs are running and i want to kill only one big query well i executed kill 17143 ok.. but when i execute this command, the query was done, and starting a second query... in other words... i killed the wrong query could we add a hash information to kill, to make it more secure and precise? for example... kill 17143 md5 "123456789......." where md5 = id + start time of query + others informations to make it relative unique maybe it exists and i don't know... any other idea how to solve this? thanks -- Roberto Spadim

[Maria-discuss] NoSQL at mysql client
by Roberto Spadim 19 Aug '13

19 Aug '13

Hi guys, i was reading some time ago about memcache (i use it for a long time ~5years or more) and the handler socket plugin Why we don't implement it at mariadb client? instead of a second library to add nosql, why not implement a built in lib? for example... (pseudo functions...) mysql_connect ... (connect to database and have permission handling...) mysql_select_db ... select the schema being used mysql_query ... execute a query command (SQL QUERIES) mysql_fetch ... get a row mysql_num_rows .. get number of rows now the nosql... mariadb_handler_socket_openindex( handler socket parameters ) mariadb_handler_socket_query mariadb_handler_socket_fetch mariadb_handler_socket_close mariadb_memcache_get mariadb_memcache_set ... this make mariadb a sql/nonsql database with a single user/permission schema, and a nice language set (SQL, handler socket, memcache, redis, drizzle, hadoop, mongodb or others...) in this case we can use the mysql protocol, but instead of sending a QUERY command, we send a "MARIADB" command, and a new parameter telling what mariadb command it is, this can be used with mysql/mariadb/percona, when used with others database probably the database will report a wrong command message but we can contact mysql to reserve a command id to "others uses", and have compatibility with any mysql fork... but the point is... instead of many connections (3-> mariadb, handler socket write, handler socket read, or 2 -> mariadb, memcached) we have only one 1-> mariadb comments are wellcome, any idea why not implement this instead of many different protocol libs? -- Roberto Spadim

[Maria-discuss] new kind of plugin
by Roberto Spadim 17 Aug '13

17 Aug '13

Hi guys, I was thinking about a new kind of plugin, a field type plugin... i think it's a relative interesting idea... about sintax: ALTER TABLE table ADD field PLUGIN("plugin_name","version","field_type","parameters") NOT NULL/NULL DEFAULT 'something' AUTOINCREMENT, etc.. an example... ALTER TABLE table ADD field PLUGIN("crypt","1","somecrypto","size=255") NOT NULL DEFAULT 'something' internally (to storage engine) this kind of data will be saved as blob (for example), and to client side it will be a blob too when i use: insert into table(field) values ("some text"); and select * from table i will get "some text" but internally (at filesystem) the value is save as a crypto of "some text" --- other idea is compress ADD field PLUGIN("crypt","1","compress","size=255") NOT NULL DEFAULT 'something' internally it will be saved as varchar(255), when i execute insert it will compress the value and when i select it will uncompress the value the parameters for this new field type is: PLUGIN(plugin name, plugin version, plugin field name, parameters) plugin name is the plugin name... plugin version is important to execute alter table, or when using diferent kind of plugin versions we could know what version is being used and execute a automatic alter table for example... plugin field is the type of field in this plugin parameters are parameters for plugin values another idea is a enum with external table... ADD field PLUGIN("external_enum",'1','enum','table=database.table,id=field_id,value=field_value') it will execute a SELECT internally to table "database.table" and return the id/value of that table id is a bigint/int/mediumint/smallint/tinyint value (like enum index) and value is a string value (varchar,char,longtext,text) to storage engine will be used a bigint, for user it will be used as a enum() field ------ thre's more examples with interesting things, like expand opengis, or add others kind of field types, but the main idea is create a plugin interface for field types what you say guys? bye =) -- Roberto Spadim

[Maria-discuss] New Question: Timestamps are different
by AskMonty KB 14 Aug '13

14 Aug '13

Hello, A new question has been asked in "Replication, Cluster, & Multi-Master" by confidus: -------------------------------- I am in the very early stages of testing out our Galara cluster with innodb databases. I have a tool that is comparing data against each node on the cluster and I have found that timestamps seem to be the only thing that is inconstant and by exactly 5 hours. I have a record in a Galera cluster that has a field with date time. I took one database and started comparing each table (one by one). I had several thousand records with different timestamps. An example is 2013-07-03 11:13:59, but another server, the date time is 2013-07-03 16:13:59. I would suspect that the times would be synced everywhere exactly the same. If I run a "SELECT NOW();" on all four servers at the same time, I see: +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ +---------------------+ | NOW() | +---------------------+ | 2013-08-13 14:59:51 | +---------------------+ If I run a select @@global.time_zone, @@session.time_zone on all four nodes in the cluster, I also see +--------------------+---------------------+ | @@global.time_zone | @@session.time_zone | +--------------------+---------------------+ | SYSTEM | SYSTEM | +--------------------+---------------------+ And if I enter date on all 4 machines, the time matches just fine. I have checked other non erip databases (some very large databases) and things are correct within those systems.
