Set MAINT: Y for jobs that perform the file backups or copies. The DB.1 panel contains a MAINT field. This field setting defines data set relationships and this job. If some of your jobs perform file backups or copies, you do not want to treat these jobs as true updates.
We recommend that you set MAINT: Y for these jobs. This setting disallows the attaching of data set requirements when the job comes into the queue. No data set updates that occur from the execution of this job are picked up. A data set that a job marked MAINT: Y created cannot trigger other work in and cannot post the data set when other jobs require it.
Business Value:
This best practice ensures more efficient processing of jobs.
