Subject [jira] [Created] (CLOUDSTACK-6892) Database HA Config prevents mgmt server from starting
Date Wed, 11 Jun 2014 10:18:01 GMT
Adrian Lewis created CLOUDSTACK-6892:

             Summary: Database HA Config prevents mgmt server from starting
                 Key: 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: 4.3.0
         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

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/

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 while refactoring out the mysql connector part"
