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
