Adrian Lewis commented on CLOUDSTACK-6892:
------------------------------------------
Added in 4.4 and Future as I assume this hasn't been picked up already.
> Database HA Config prevents mgmt server from starting
> -----------------------------------------------------
>
> Key: CLOUDSTACK-6892
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-6892
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Install and Setup, Management Server
> Affects Versions: Future, 4.3.0, 4.4.0
> Environment: MySQL configured for DB HA
> Reporter: Adrian Lewis
> Priority: Critical
>
> When configuring the database HA feature introduced in 4.3, the manangement
> server fails to create the DB connection due to the mysql connector jar being
> loaded using tomcat's common class loader but the
> "cloud-plugin-database-mysqlha-4.3.0.jar" is loaded by the webapp class
> loader.
> The cloud-plugin-database-mysqlha-4.3.0.jar needs to also be loaded from the
> common class loader instead of webapp class loader.
> Fix is to declare the cloud-plugin-database-mysqlha-4.3.0.jar under the
> common.loader section in /etc/cloudstack/management/catalina.properties.
> Only tested using a fresh install on Centos 6.5 and the public repo packages.
> Manual fix provided by Damoder Reddy in users mailing list: "Looks like we
> did not change the catalina.properties while refactoring out the mysql
> connector part"
