offloads as much processing as possible to zIIPs.

Tip

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

You can disable the use of zIIPs by specifying OPTIONS ZIIP DISABLED.

  • REORG PLUS
  • UNLOAD PLUS

The default value for the System Management Facility (SMF) MEMLIMIT parameter is 2 GB.

For most jobs, we recommend a value of at least 2 GB for the MEMLIMIT parameter. However, if you are operating on LOB or XML data, we recommend a value of at least 32 GB.

This value is set in member SMFPRMxx in SYS1.PARMLIB. Use any of the following methods if you need to override the default value:

  • Specify the MEMLIMIT parameter in the JCL.
  • Specify REGION=0M in the JCL.
  • Use the SMF IEFUSI exit.

Software requirements

This version of

  • You must have a minimum of version 13.1.00 of the BMC Db2 Solution Common Code (SCC) installed.
