Setting the Job Priority

Setting Job Priority allows you to change the priority of a job or a group of jobs. You can use it to prioritize jobs based on your requirements by changing their job priority value.

After changing the job priority, if a higher priority job interrupts another lower priority job for resources, then the Job Manager interrupts the running job and allocates the freed resources to a higher priority job only if Job Preemption is allowed.

For Administration Jobs

You can change the priority of the following administration jobs:

  • Auxiliary Copy

  • Data Verification

  • Information Management

  • Media Refresh

  • Persistent Recovery

Note

Auxiliary copies honor job priorities only when Scalable Resource Allocation is enabled for the Auxiliary copy operation. If reservation requests are sent at the same time by two jobs with differing priorities, then the priorities are not honored because the reservations will be processed.

Exception: Job priorities for the IntelliSnap backup copy operation.

  1. From the CommCell Console ribbon, on the Home tab, click Control Panel.
