[Maria-discuss] R: CONNECT storage engine
by Federico Razzoli 24 Dec '15

24 Dec '15

A new version of CONNECT package was released, but you have still 10.1.9. The packages don't conflict, but versions are incompatible. Just run apt-get upgrade and CONNECT will work.

Re: [Maria-discuss] enforce_storage_engine galera cluster
by Federico Razzoli 22 Dec '15

I didn't suggest to use MyISAM :) Now I understand your purpose. If you use MaxScale, you can use a filter and replace MyISAM with InnoDB. Something like: /engine( )*=( *)myisam/i And you can use similar regexps for each storage engine. The filter that you need is this one: https://github.com/mariadb-corporation/MaxScale/blob/master/Documentation/F… Hope that this helps.

Anyway, this bug seems to break our plans, so we should report the bug and find another way in the meanwhile....in addition, MyISAM replication is described as experimental and we don't want to use it in such early development phase.

[Maria-discuss] enforce_storage_engine galera cluster
by Michele Tota 22 Dec '15

22 Dec '15

Hi, we have a problem using enforce_storage_engine variable set to InnoDB. We have three servers in cluster (multi masters). When we issue create table with engine=MyISAM the engine is correctly enforced to InnoDB only on the node we are connected to. On the other nodes the replicated table is created as MyISAM. This is our servers configuration, the same on all nodes: ... enforce_storage_engine='InnoDB' wsrep_on=ON sql_mode='' ... How can we enforce InnoDB on all nodes? Thanks, Michele

[Maria-discuss] Announcing release for MariaDB 5.5 and 10.0 on CentOS Linux 6 and 7 x86_64 SCL
by Honza Horak 21 Dec '15

21 Dec '15

I am pleased to announce the immediate availability of versions 5.5 and 10.0 of the MariaDB server on CentOS Linux 6 and 7 x86_64, delivered via a Software Collection (SCL) built by the SCLo Special Interest Group (https://wiki.centos.org/SpecialInterestGroup/SCLo) QuickStart ---------- You can get started in three easy steps (example of MariaDB 10.0): $ sudo yum install centos-release-scl $ sudo yum install rh-mariadb100 $ scl enable rh-mariadb100 bash At this point you should be able to use MariaDB just as a normal application. An examples of commands run might be: $ service rh-mariadb100-mariadb start $ mysql In order to view the individual components included in this collection, including additional subpackages plugins, you can run: $ sudo yum list rh-mariadb100\* About Software Collections -------------------------- Software Collections give you the power to build, install, and use multiple versions of software on the same system, without affecting system-wide installed packages. Each collection is delivered as a group of RPMs, with the grouping being done using the name of the collection as a prefix of all packages that are part of the software collection. The collection rh-mariadb100 delivers version 10.0 of the MariaDB server (with daemon called rh-mariadb100-mariadb) and related client tools. The collection mariadb55 delivers version 5.5 of the MariaDB server (with daemon called mariadb55-mariadb) and related client tools. Both the collections include no client library libmysqlclient.so and client applications are advised to use the client library available in mysql-libs package from base system. For more on the MariaDB, see https://mariadb.org. The SCLo SIG in CentOS ---------------------- The Software Collections SIG group is an open community group co-ordinating the development of the SCL technology, and helping curate a reference set of collections. In addition to the MariaDB collections being released here, we also build and deliver other databases, web servers, and language stacks including multiple versions of MySQL, PostgreSQL, MongoDB Apache HTTP Server, NodeJS, Ruby, Python and others. Software Collections SIG release was announced at https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html You can learn more about Software Collections concepts at: http://softwarecollections.org You can find information on the SIG at https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto get involved and help with the effort. We meet every second Wednesday at 16:00 UTC in #centos-devel (ref: https://www.centos.org/community/calendar) for an informal open forum open to anyone who might have comments, concerns or wants to get started with SCL's in CentOS. Enjoy! Honza SCLo SIG member

[Maria-discuss] New Question: Slow query log and long_query_time
by AskMonty KB 18 Dec '15

18 Dec '15

Hello, A new question has been asked in "Slow Query Log" by yu.d.sun_32615. Please answer it at http://mariadb.com/kb/en/slow-query-log-and-long_query_time/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- In my understanding if we enable slow query log, MySQL will capture all SQL statements that take more than long_query_time seconds to execute into the log. If so below testing puzzled me: Server version: 10.0.21-MariaDB-wsrep-log MariaDB Server, wsrep_25.10.r4144 === in the mysql CLI ================== ip-10-74-2-218$ root@localhost[galeratest] MYSQL> select now(); +---------------------+ | now() | +---------------------+ | 2015-12-18 11:12:50 | +---------------------+ 1 row in set (0.00 sec) ip-10-74-2-218$ root@localhost[galeratest] MYSQL> show variables like 'long%'; +-----------------+-----------+ | Variable_name | Value | +-----------------+-----------+ | long_query_time | 10.000000 | +-----------------+-----------+ 1 row in set (0.00 sec) ip-10-74-2-218$ root@localhost[galeratest] MYSQL> select count(*) from test_table; +----------+ | count(*) | +----------+ | 13 | +----------+ 1 row in set (0.00 sec) ip-10-74-2-218$ root@localhost[galeratest] MYSQL> select sleep(5); +----------+ | sleep(5) | +----------+ | 0 | +----------+ 1 row in set (5.00 sec) ip-10-74-2-218$ root@localhost[galeratest] MYSQL> select sleep(11); +-----------+ | sleep(11) | +-----------+ | 0 | +-----------+ 1 row in set (11.00 sec) ip-10-74-2-218$ root@localhost[galeratest] MYSQL> select count(*) from test_table; +----------+ | count(*) | +----------+ | 13 | +----------+ 1 row in set (0.00 sec) ip-10-74-2-218$ root@localhost[galeratest] MYSQL> ==== from the slow query log ================== # Time: 151218 11:13:12 # User@Host: root[root] @ localhost [] # Thread_id: 125 Schema: galeratest QC_hit: No # Query_time: 0.000163 Lock_time: 0.000075 Rows_sent: 1 Rows_examined: 13 SET timestamp=1450465992; select count(*) from test_table; # Time: 151218 11:13:48 # User@Host: root[root] @ localhost [] # Thread_id: 125 Schema: galeratest QC_hit: No # Query_time: 11.002494 Lock_time: 0.000000 Rows_sent: 1 Rows_examined: 0 SET timestamp=1450466028; select sleep(11); # Time: 151218 11:14:10 # User@Host: root[root] @ localhost [] # Thread_id: 125 Schema: galeratest QC_hit: No # Query_time: 0.000159 Lock_time: 0.000073 Rows_sent: 1 Rows_examined: 13 SET timestamp=1450466050; select count(*) from test_table; ================ Question - why the 'select count(*) from test_table' statement is captured while it seems right that select sleep(11) got captured and sleep(5) did not? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/slow-query-log-and-long_query_time/
