| Parameter | Specify . . . | Possible Values | Default |
|---|---|---|---|
| PGFIX | whether pages containing I/O control blocks are released after I/O processing is completed or after the job has ended when using EXCPVR on z/OS systems. | YES | NO | NO |
This parameter is only valid for z/OS users using EXCPVR (for example, when running the Adabas nucleus or utility jobs APF-authorized). It allows you to control how page-fixing occurs when EXCPVR is in use. When PGFIX=NO is specified, pages containing the I/O control blocks are fixed only for the duration of the I/O processing. When PGFIX=YES is specified, pages containing the I/O control blocks are fixed for the duration of the job.
