[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

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/

[Maria-discuss] Question about Galera "pc.recovery" feature
by Marco Nicosia 05 Jun '15

05 Jun '15

Hi all! We recently discovered the configuration wsrep_provider_options="pc.recovery=TRUE" and set about to set this configuration, as we'd like to avoid unnecessary boostrapping whenever possible. We were further surprised to discover that this feature had been enabled by default. But we were frustrated in our attempts to trigger this feature to actually observe it in action. I understand that the feature is intended to recover from full cluster crashes _such as_ a power outage, but we were unable to come up with a scenario in which we could interrupt the cluster and watch it recover automatically. This included deploying to AWS and setting all three nodes to 'stop' then 'start.' In each instance, we had to manually bootstrap. Am I misunderstanding the feature, or the conditions under which we can trigger it? -- Marco Nicosia Product Manager Pivotal Software, Inc. mnicosia(a)pivotal.io c: 650-796-2948

[Maria-discuss] New Question: Switch over at a database level
by AskMonty KB 04 Jun '15

04 Jun '15

Hello, A new question has been asked in "Standard Replication" by mahoarita. Please answer it at http://mariadb.com/kb/en/switch-over-at-a-database-level/ as the person asking the question may not be subscribed to the mailing list. -------------------------------- Is it possible to switch over an individual database? For example, with the below scenario: - I have 3-server replication - Server contains multiple databases owned by different users I'd like to manually switch over only one database, "MyDb1" as a failover test. The rest of the databases residing on the same MariaDB server should not be impacted. This is to minimize the impact to other databases for failover test exercise. Is this possible by Standard Replication? I'd be grateful for this information. -------------------------------- To view or answer this question please visit: http://mariadb.com/kb/en/switch-over-at-a-database-level/
