Oracle RAC Multi Instance Job Throttling
When job throttling is configured for an Oracle RAC pseudo client, the threshold values are shared by all instances configured for the pseudo client.
The Oracle RAC pseudo client Rac_MultiInstance has the data threshold set to 2 and the log threshold set to 3. There are 3 instances configured for the pseudo client: databaseX, databaseY and databaseZ. If databaseY and databaseZ are running backup jobs, a backup job that is started for databaseX is queued and waits for one of the jobs to reach the log backup phase.
