VTAPE_PARM_zIIP_STATUS

Description

IBM zIIP specialty processors are installed and available for use yet CA Vtape is not currently configured to take advantage of these specialty processors.

Best Practice

Investigate and evaluate the use of zIIP specialty processors for CA Vtape. The use of zIIP specialty processors by CA Vtape increase performance and lower general processor usage.

The CA Vtape use of zIIP specialty processors is controlled by the zIIPExploitation and PercentRunOnZIIP attributes defined in the respective Startup Options and Dynamic Options Sections of the CA Vtape parmlib.

To enable CA Vtape exploitation of zIIP specialty processors, specify the zIIPExploitation attribute as zIIPExploitation=Y, and set the PercentRunOnzIIP attribute to a value greater than 0.

Parameters Accepted

None

Debug Support

Yes

Verbose Support

Yes

Reference
