zIIPs

If IBM System z Integrated Information Processors (zIIPs) are available, elect to use zIIPs when you set up your regions.

Business Value:

Using zIIPs provides the following benefits:

• Reducing the execution time on the normal central processing unit (CPU), providing savings in billable CPU time
• Freeing up processing cycles from the CPU to other work
• Exploiting the processing power of zIIPs

More Information:

The following JCL parameters control the usage of zIIPs: PAEXMODE for the SOLVE Subsystem Interface and XM for the region. For information about the parameters, see the SOLVE Subsystem Interface Guide and the Reference Guide.
