In z/OS environments, you can use the z/Architecture Integrated Information Processor (zIIP) to offload processing cycles from the main CP processors. This processing lets other work execute on the main CP processors while CA WA CA 7 Edition code executes on the zIIP processor. Although some overhead is involved in setting up to use zIIP processors, moving CA WA CA 7 Edition processing to zIIP typically decreases overall costs. The following subtasks are zIIP-enabled:
The initialization file contains a new keyword in the INIT initialization statement: ZIIP={NO|YES}. Unless you modify the initialization file, no processing in the CA WA CA 7 Edition address space executes on a zIIP processor. If you specify INIT,ZIIP=YES, CA WA CA 7 Edition checks to see whether a zIIP processor is enabled for this LPAR. If a zIIP processor is available, CA WA CA 7 Edition uses the zIIP Enablement Service feature in CA Common Services r14.0 or above to let selected subtasks execute on a zIIP processor. If not, a warning message is issued, and all processing and execution continue on the main CP processors.
You can use the /DISPLAY,PERF=ZIIP to display the zIIP processing performance.
Note: For more information about the ZIIP parameter, see the Systems Programming Guide.
