The MEMLIMIT parameter is used to specify the virtual memory limit (above the default limit) that a job can use from the total virtual memory space. It is a keyword parameter and is optional.

Syntax -

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

MEMLIMIT=0M means the job can’t be able to use virtual memory (above the default limit).

Default and overrides -

• If MEMLIMIT is not specified and REGION=0M, the default value is set by SMF.
• If MEMLIMIT is not coded, the default value is NOLIMIT.
• If MEMLIMIT coded at both job and step level, MEMLIMIT at step level has high priority.

Examples -

Scenario - 99MB virtual memory at JOB level.

//MTHEXMP1 JOB (MTH007),'PAWAN Y',MEMLIMIT=99M 

The job can use upto 99 megabytes of virtual memory above the default limit.
