Error description
ObjectGridException exception is thrown with message "Security is enabled but there is no SubjectSource plugin set on the ObjectGrid instance", when another container joins the grid. Customer was experiencing a ReplicationVotedToRollbackTransactionException when a client attempts to update an entry in a grid where the shards have been re-placed. If they change the grid.xml file to specify securityEnabled=false, they cannot recreate the issue. When security is enabled, start a third container, causing the shards to be re-balanced results in an FFDC entry. key = com.ibm.websphere.objectgrid.ObjectGridException com.ibm.ws.objectgrid. replication.PrimaryShardImpl.seizeLeadership 260 Exception = com.ibm.websphere.objectgrid.ObjectGridException Source = com.ibm.ws.objectgrid.replication.PrimaryShardImpl.seizeLeadersh ip probeid = 260 Stack Dump = com.ibm.websphere.objectgrid.ObjectGridException: Security is enabled but there is no SubjectSource plugin set on the ObjectGrid instance.
