ZIIP

The ZIIP option tells BMC AMI Recover whether to attempt to use IBM System z Integrated Information Processors (zIIPs). BMC AMI Recover can use enclave service request blocks (SRBs) to enable zIIP processing automatically while running jobs. Using zIIP processing can reduce the overall CPU time for BMC AMI Recover jobs.

You can specify the default for the ZIIP command option in your installation options module by using the ZIIP installation option (ZIIP-ENABLED). 

BMC AMI Recover

 was shipped with a default value of ENABLED for this option. The ZIIP option on the OPTION command overrides the default that is in the installation options module.

Description

ZIIP ENABLED

ZIIP ENABLED tells BMC AMI Recover to attempt to offload eligible processing to an available zIIP. If the zIIP is busy or not available, normal processing continues on a general-purpose processor.

To enable and use zIIP processing with BMC AMI Recover, you must:

  • Have an installed authorized version of XBM or SUF
  • Start and maintain an XBM subsystem in your environment
  • Have a zIIP available in your environment

Tip

When you use zIIP processing, we recommend that you specify IIPHONORPRIORITY=YES in the IEAOPT member of SYS1.PARMLIB.

You can specify a particular XBM subsystem to use by specifying a value for the XBMID installation option (XBMID-ssid-or-xbmGroup) or XBMID option on the OPTION command (XBMID-ssid-or-XBMID-xbmGroup).

XBM and SUF are licensed, installed, and maintained separately from BMC AMI Recover. You can use either XBM or SUF, depending on the license that you have obtained:

  • A license for the full version of the XBM product authorizes you to use all features of XBM.
  • A license for SUF authorizes you to use only the snapshot and zIIP-processing features of XBM.

For more information about XBM and SUF, see theSNAPSHOT UPGRADE FEATURE documentation. 

ZIIP DISABLED

ZIIP DISABLED tells BMC AMI Recover to not attempt to use zIIP processing.
