Understanding the Job Priority setting

NetBackup uses the Job Priority setting as a guide. Requests with a higher priority do not always receive resources before a request with a lower priority.

The NetBackup Resource Broker (NBRB) maintains resource requests for jobs in a queue.

NBRB evaluates the requests sequentially and sorts them based on the following criteria:

The first priority is weighted more heavily than the second priority, and the second priority is weighted more heavily than the birth time.

Because a request with a higher priority is listed in the queue before a request with a lower priority, the request with a higher priority is evaluated first. Even though the chances are greater that the higher priority request receives resources first, this is not always definite.

The following scenarios present situations in which a request with a lower priority may receive resources before a request with a higher priority:
