To make most changes to a job's attributes you need to have either job control special authority (*JOBCTL) or your user profile needs to match the job user identity of the job being changed.
There are a few attributes where having *JOBCTL special authority is necessary to make any changes. These attributes are:
- Default wait time
- Run priority
- Time slice
Note: If you plan to make changes to the job's accounting code, you need *USE
authority to the Change Accounting Code (CHGACGCDE) command
in addition to *JOBCTL special authority or a user profile matching the job's
job user identity.
For any job attributes that refer to an iSeries™ object, such as job queues, output
queues, and sort sequence tables, then you need to have the proper authority
to the object. For more details on iSeries authorities, see Appendix D Authorities
Required for Objects Used by Commands in the iSeries Security
