I use Enterprise manager to run backups on our database, one backup is stored locally and one goes to the cloud. Both backups are dying every night to Error evaluating parameter sources/security checks/locks ORA-20224: Could not resolve instance for cluster/redundancy group <databaseName>:rac_database. I've tried restarting the agents on both of the oda nodes. I've tried restarting OMS. I've tried power cycling both database nodes. Nothing seems to resolve the issue.
Any recommendations would be great,
