OVLA= parameter for procedures
Use the OVLA= parameter in procedures to specify the overlay supervisor option. Valid values are 0 or 1. The default is 0.
The possible overlay supervisor options are:
- 0
- Allow z/OS® to load and delete the overlay supervisor for every overlay application program. This is the default.
- 1
- Load and retain a copy of the overlay supervisor when the message region is initialized.
You can set the OVLA= parameter using the DFSOPT DD statement in IMS-supplied procedures. The syntax for the OVLA= parameter is:
OVLA=0|1 (The default
is 0.)
For more information, see DFSOPT DD in DD statements for IMS procedures.
