The zIIPExploitation attribute indicates that SVTS uses the zIIP specialty processors to process virtual I/O activity. However, the PercentRunOnzIIP attribute indicates that no work is scheduled on those processors.
The use of zIIP specialty processors in a CA Vtape environment offers superior performance advantages over non-zIIP processor configurations. Evaluate the zIIPExploitation and PercentRunOnzIIP attributes defined in the respective Startup Options and Dynamic Options sections of the respective CA Vtape parmlib. Change the attributes to enable CA Vtape exploitation of zIIP if a zIIP specialty processor is installed.
To enable CA Vtape exploitation of zIIP, specify the zIIPExploitation attribute as zIIPExploitation=Y, set the PercentRunOnzIIP attribute to a value greater than 0, and restart CA Vtape.
To disable CA Vtape exploitation of zIIP, specify the attribute as zIIPExploitation=N and restart CA Vtape.
