The owner of all Replication Agent system objects, including shared and instance-specific system objects.
When ra_admin_owner is not configured, it uses the value of the pds_username parameter.
The user name specified by ra_admin_owner must be defined in the primary data server.
You cannot change the value of the ra_admin_owner parameter after a Replication Agent instance has been created.
Each Replication Agent instance in a Replication Agent group must be configured with the same value for ra_admin_owner.
