[Maria-discuss] Password Complexity Plugin
by Adam Scott 01 May '15

01 May '15

Hi, I noticed MySQL 5.6 has a validate_password plugin. Since it's open-source, can we add it to MariaDB 5.5. Or is that bad form, a hot potato, etc.? We need the features of this plugin in our environment, and the PAM integration is looking not a good "fit" (though it's working great). (I'm trying to get it to compile in right now, but it's having issues with the includes so far...working on it). Thanks, Adam C. Scott

[Maria-discuss] One node out of cluster keeps crashing
by Momin Rashid 31 Mar '15

31 Mar '15

Hello everyone, MariaDB-Galera-server-10.0.17-1.el7.centos.x86_64 MariaDB-client-10.0.17-1.el7.centos.x86_64 galera-25.3.9-1.rhel7.el7.centos.x86_64 We have a three node MariaDB-galera cluster, and one of our nodes keeps crashing. The other two nodes have been running fine for weeks without issues. They all have the exact same specifications. I have even rebuilt this node from ground up, and the new node still crashed. Could someone take a look at the following logs and help me figure out what is wrong, and how can we avoid this in future? ===================================== 2015-03-30 10:13:05 7f5be57fc700 INNODB

[Maria-discuss] New Question: Please list OS requirements.
by AskMonty KB 31 Mar '15

31 Mar '15

Hello, A new question has been asked in "Graphical Clients" by openiduser56. Please answer it at http://mariadb.com/kb/en/please-list-os-requirements/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- It' quite annoying to have to click around the destination website to try to work out what it takes to actually run the tool. I suspect most people looking for a GUI tool already have an operating system they want it to run on, and sometimes even restrictions on how much extra stuff they can install to get it working. So saying "runs on MacOS... you just need Parallels and a Windows licence" is unlikely to make sense. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/please-list-os-requirements/

[Maria-discuss] Reason for changing the thread_pool_size default value?
by Ian Gilfillan 19 Mar '15

19 Mar '15

Hi What was the reason for changing the default thread_pool_size from the number of CPU's to 8? If I look at the history of sql_vars.cc - https://github.com/MariaDB/server/commits/10.1/sql/sys_vars.cc?page=2 - the commit made on the 17th of November still has it as the number of CPU's, but the next commit on the 2nd of December has it at 8. This doesn't appear as a change in the summary. ian

[Maria-discuss] New Question: MS-SQL Server Change tracking
by AskMonty KB 18 Mar '15

18 Mar '15

Hello, A new question has been asked in "Moving to MariaDB" by peterhorwood. Please answer it at http://mariadb.com/kb/en/ms-sql-server-change-tracking/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- I'm looking at having our product add MariaDB as a database we support. Currently we only support MS-SQL. One issue I'm wondering about is change tracking. Does MariaSQL have anything like the SQL Server (2008 and newer) Server change tracking? Or do I need to 'roll my own' using insert/update/delete triggers? -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/ms-sql-server-change-tracking/
