[Maria-discuss] DELETE FROM RETURNING
by Rhys Campbell 12 Jun '15

12 Jun '15

Hello All, Just regarding the RETURNING feature introduced into MariaDB 10.0.5 https://mariadb.com/kb/en/mariadb/delete/ It would be useful, similar to the OUTPUT clause in MSSQL, if we could INSERT the data sent back from a returning clause in a single statement. Something like... CREATE TABEL deleted_ids ( Id INT NOT NULL PRIMARY KEY ); INSERT INTO deleted_ids DELETE FROM t1 WHERE id < 999 RETURNING id; Rhys Campbell Database Administrator TradingScreen, Inc. 23 York House, 5th Floor London WC2B 6UJ Email: rhys.campbell(a)tradingscreen.com<mailto:rhys.campbell@tradingscreen.com> Follow TradingScreen on Twitter<http://twitter.com/#!/TradingScreen> , Facebook<http://www.facebook.com/pages/TradingScreen/214046251945650> and our blog Trading Smarter<tradingsmarter.tradingscreen.com> This message is intended only for the recipient(s) named above and may contain confidential information.

[Maria-discuss] MariaDB 5.5 apt repo for Ubuntu 10.04 no longer exists
by Bryan Traywick 11 Jun '15

11 Jun '15

I noticed today that the MariaDB 5.5 apt repository for Ubuntu 10.04 no longer exists. At first I thought this was due to the EOL for 10.04 but the 10.0 apt repository is still present in the repository configurator. I couldn’t find an announcement announcing the termination of these repositories. Is this a temporary oversight or are these apt repositories gone forever? Thanks, — Bryan Traywick

[Maria-discuss] New Question: MariaDB service fails to start after InnoDB/XtraDB crash

Hello, A new question has been asked in "XtraDB and InnoDB" by kushkash. Please answer it at http://mariadb.com/kb/en/mariadb-service-fails-to-start-after-innodbxtradb-… as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi, I've been running a script, inserting a large amount of data to several MySQL tables. Apparently, InnoDB crashed at some point (when ibdata1 reached ~1.6 Gb). I had to restart the computer and when I tried to restart MariaDB service, I got the following errors: Jun 11 08:58:02 honolulu.bi.technion.ac.il mysqld_safe[7970]: 150611 8:58:02 InnoDB: Operating system error number 5 in a file operation.

I really need help on this issue... 1. What might have cause the problem? Do I have to configure some InnoDB parameters? Maybe the ibdata file size is a problem? 2. How to recover my data and restart the MariaDB service? (I tried all kind of tips I found in other forums, but I couldn't backup the ibdata1 file or start InnoDB in recovery mode). -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/mariadb-service-fails-to-start-after-innodbxtradb-…

[Maria-discuss] 2 node cluster crash
by absolutely_free＠libero.it 10 Jun '15

10 Jun '15

Hi, I have two node cluster with Mariadb (5.5.43) Both servers are equal (RAM, CPU, disk) and they are in same lan segment. I use official MariaDB package from this repository: deb http://mariadb.kisiek.net//repo/5.5/debian wheezy main I use haproxy with this config: # cat haproxy.cfg global log /dev/log local0 log /dev/log local1 notice chroot /var/lib/haproxy user haproxy group haproxy daemon maxconn 8192 defaults retries 2 timeout connect 30s timeout server 600s timeout client 600s log global listen mariadb-cluster bind 0.0.0.0:3306 mode tcp option mysql-check user haproxy option tcpka balance leastconn server node1 192.168.100.1:3307 check maxconn 4096 server node2 192.168.100.2:3307 check maxconn 4096 listen webinterface bind 0.0.0.0:8080 mode http stats enable stats uri / stats realm Strictly\ Private stats auth Username:Password Often (about 1 time per week) several applications that rely on databases on this cluster encounter problems. When this happens, I check on both machines and I see that mysql is running. When I stop mysql on one node (let's say, node2), all returns working fine. I am trying to find the root cause of this behavior.

Hello, A new question has been asked in "MariaDB Community" by nunocarapito. Please answer it at http://mariadb.com/kb/en/mariadb-keeps-crashing-on-some-wordpress-posts/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi there. I have a mariadb server with 2 wordpress blogs. Sometimes, when an admin posts something in it, it crashes. I've updated it, and it still happens. Not sure what else Should I do.

[Maria-discuss] 2015 leap second issues?
by Marco Nicosia 06 Jun '15

06 Jun '15

Hi all, I'm writing to inquire if I should prepare any of our MariaDB/Galera users for the upcoming leap second. According to http://www.timeanddate.com/time/leapseconds.html the next leap second will be added on June 30, 2015 at 23:59:60 UTC. I searched a bit for "leap second mariadb" but didn't find anything recent. Most of our users are on MariaDB 10.0.13 and Galera 25.2.9 or subsequent. Have anyone tested both MariaDB and Galera to ensure that there are versions which are resilient to the introduction of a leap second? If so, is there documentation of versions which are known vulnerable to or proof against it? Thanks! -- Marco Nicosia Product Manager Pivotal Software, Inc.

[Maria-discuss] New Question: Converting from MySQL to MariadB
by AskMonty KB 05 Jun '15

Hello, A new question has been asked in "MariaDB Community" by cavj1. Please answer it at http://mariadb.com/kb/en/converting-from-mysql-to-mariadb/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Hi All... I'm in the process of moving from MySQL to MariadB for our web app. Within the web app we use various Crystal Reports that run on the server and present the report to the user. The report currently uses a MySQL ODBC connector. IF I modify the ODBC connector to point to the new server will the MySQL ODBC connector still work? Does anyone know if the MySQL ODBC connector is compatible with MariadB? Otherwise I'd have to modify every report in the system to use the new connector which will be very time consuming. Thank you for any input you provide. Joe -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/converting-from-mysql-to-mariadb/
