Hi All,
I have a JCL as shown below.
//EFBTH JOB (10403),'RATAR JOB',MSGLEVEL=(1,1),MSGCLASS=H,
// REGION=0M,CLASS=P,NOTIFY=&SYSUID,
//S1 EXEC PGM=PROG1,REGION=20K
//DD1 DD DSNAME=A.B.C,DISP=OLD
//S2 EXEC PGM=PROG2,
//DD2 DD DSNAME=MYDS2,DISP=OLD
Query 1 : Please advise, in case the REGION=0M set in the job card is over ridden by the REGION=20K in the step1(S1) and the same REGION=20K is used in all subsequent steps?
Query 2 : Is there any chance that the Job class(CLASS=P) has a limitation set on the memory allocation?
Thanks in advance
Regards
Siva |

Hi,
query1 - A REGION= value on the JOB statement will override any REGION= specified on an EXEC statement in the job
A value of 0K or 0M will allow the program to request the largest available region size, however this specification should be used with caution. Check the OS/390 Initialization and Tuning Guide

classes and their properties are installation dependent, so we have noo way of knowing about them,
ask Your support |

the same info could have been easily found in the jcl manuals
( guide and reference ) link at the top of the page
and since You claimed urgency, faster than a forum reply |
