What is MEMLIMIT parameter? - IBM-JCL

Parameter Type

Keyword, optional

Purpose

Use the MEMLIMIT parameter to specify the limit on the total number of usable virtual pages above the bar for a single address space.

1.Syntax

MEMLIMIT={nnnnnM } {nnnnnG } {nnnnnT } {nnnnnP } {NOLIMIT}

2.Subparameter Definition

nnnnnM
nnnnnG
nnnnnT
nnnnnP
Specifies a value to be used as the limit on the total number of usable virtual pages above the bar in a single address space. The value may be expressed in megabytes (M), gigabytes (G), terabytes (T), or petabytes (P). nnnnn may be a value from 0 to 99999.

NOLIMIT
Specifies that there is no limit on the virtual pages to be used above the bar.

3.Defaults
If no MEMLIMIT parameter is specified, the default is the value defined to SMF, except when REGION=0K/0M is specified, in which case the default is NOLIMIT.

4.Overrides
Specifying MEMLIMIT on the JOB statement overrides MEMLIMIT on the EXEC statement.

If MEMLIMIT is not specified, SMF provides a default value. The IEFUSI installation exit can override any JCL- or SMF-supplied value.

5.Examples of the MEMLIMIT Parameter

//TEST JOB ’D83,123456’,MEMLIMIT=10000M

This statement specifies that the job is limited to the use of 10000 megabytes of usable virtual pages above the bar.
