Environment

Release : 12.1

Component : CA WORKLOAD AUTOMATION AE IDASH

Cause

In an Oracle RAC installation, the primary and secondary server installs are accessing the same database.

Resolution

Messages can be ignored since this is the secondary iDash server. The objects already exist in the database from the primary iDash server installation. Application install will complete successfully.
