MariaDB Enterprise Server and Cluster 10.0.14 Release Notes and Changelog

Release date: 9 Dec, 2014

MariaDB Enterprise Server 10.0.14 Release Notes

This version of MariaDB Enterprise is built off MariaDB 10.0.14. In addition to the many fixes and improvements in 10.0.14, the following additional work has been done:

• The release includes a fix for a serious bug in InnoDB and XtraDB that sometimes could cause a hard lock up of the server (MDEV-7026). This fix was backported from MariaDB 10.0.15.

• MariaDB Enterprise 10.0.14 is the first version of MariaDB Enterprise that officially supports IBM’s POWER8 architecture. With this release there are now POWER8-compatible installation packages for Red Hat Enterprise Linux 6, Red Hat Enterprise Linux 7, and Ubuntu 14.04.

• MariaDB Enterprise now comes with something called Notification Services, which notify users whether new releases of MariaDB Enterprise include bug fixes or improvements for features that the user are using. To get your activation code & installation instruction, please contact our sales team.

• The my.cnf configuration file has been updated to provide better general default values for running MariaDB Enterprise. The previous default values were in many cases outdated. This new mariadb-enterprise.cnf is included in the binary releases of MariaDB Enterprise available for download from our customer portal. On RPM-based and debian platforms it gets installed /etc/my.cnf.d/ and /etc/mysql/conf.d/ respectively. You’ll get the new mariadb-enterprise.cnf built right in - and can use it without any additional steps.

• Plugins that are not yet GA-quality have been disabled and unloaded. Those which are at the “stable” or “gamma” maturity level will be immediately available for your installation - available to use. These features are fully supported as part of your subscription and you can call us with any issues. See the Pre Loaded & Supported Plugin list to get more details about each plugin status and to get the instructions on how to upload and enable the plugins not pre loaded by default. We’ll answer questions about these plugins as best as we can but they’re not supported.

• A high-priority fix for CentOS 7 and Red Hat Enterprise Linux 7 packages was also backported from MariaDB 10.0.15 (MDEV-6886)

• As always with MariaDB Enterprise, additional testing and checks have been done to ensure the highest quality.

MariaDB Enterprise on POWER8 Notes

The binaries and packages for MariaDB on POWER8 does not include the following storage engines:

• Connect
• OQGraph
• TokuDB

On Red Hat Enterprise Linux 7 there exists a missing memory barrier bug that can cause MariaDB to crash. Until this bug is fixed in the kernel of the operating system it’s recommended to disable InnoDB’s use of native AIO by adding skip-innodb-use-native-aio into the [mysqld] section of the my.cnf configuration file.

Earlier version of MariaDB Enterprise

As a reminder, the following items were added to the previous version of MariaDB Enterprise, version 10.0.12:

• Plugins that are not yet GA-quality have been disabled and unloaded. To use them you will need to load them and explicitly enable them. See the Plugin Maturity page in the MariaDB Knowledge Base for a table of plugins and their maturity level. Any plugin that is not marked as either Stable or Gamma is disabled and unloaded in MariaDB Enterprise.

• Also relate to the plugins, the MariaDB Audit plugin is loaded by default.

• Some small updates have been made to the default my.cnf file.
