REGION= & TIME= Narrative

This page discusses the REGION= and TIME= operands seen on the previous page.

The REGION= operand when coded on the JOB statement assigns memory, RAM if you like, for the ENTIRE JOB. Too small a value causes the JOB to ABEND.

The TIME= operand sets the maximum CPU occupancy for the JOB. If omitted in JES2, the likely default will come from JES2PARM. Too small a value will produce an S322 ABEND.

JOB Statement purpose (2) - narrative

REGION=

The REGION= operand is used to allocate memory below the 2GB bar. Memory can be requested in units of kilobytes (K) or megabytes (M). For example REGION=4096K is the same as REGION=4M.

When coded on the JOB Statement it overrides all values on EXEC statements within the JOB. If omitted in JES2, the likely default will be from JES2PARM. MEMLIMIT is used to assign memory above the 2GB boundary.

TIME=

The operand has two sub-parameters so could be coded in the following ways:

• TIME=4 - allow 4 minutes
• TIME=(2,30) - allow 2 mns 30 seconds
• TIME=(0,30) - allow 30 seconds

NOTIFY=

This has nothing to do with resource allocation but provides notification of completion to a single user.
