ZIIP option

The ZIIP option tells PACLOG whether to attempt to use IBM System z Integrated Information Processors (zIIPs). PACLOG 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 PACLOG jobs.

You can specify one of the following values:

Value

Description

ENABLED

Tells PACLOG 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.

DISABLED

tells PACLOG not to attempt to use zIIP processing.

To enable and use zIIP processing with PACLOG, you must:

  • Have an installed, authorized version of the EXTENDED BUFFER MANAGER (XBM) product or the associated SNAPSHOT UPGRADE FEATURE (SUF) technology
  • Start and maintain an XBM subsystem in your environment
  • Have a zIIP available in your environment

You can specify a particular XBM subsystem to use by specifying a value for the XBMID option (with a length of up to 8 characters). If you omit the XBMID option, PACLOG will discover an XBM subsystem that meets the requirements for zIIP processing.

Important

XBM and SUF are licensed, installed, and maintained separately from PACLOG. You can use either XBM or SUF, depending on your license:

  • 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.
