How to delete particular DDNAME/STEP from a job using REXX

Postby Lakshmi M » Fri Mar 02, 2012 1:24 pm

Hi Everyone,

Please can anybody help me out in resolving this.
Currently I’m working on NATURAL & ADABAS. & I’m learning REXX only because of to implement this logic.
In a JOB, particularly I want to retain CMPR* named DDnames reset I want to delete.

>>> Input

Select all
 DDname   Stepname     Procstep    Status

  JESMSGLG  JES2                         HELD
 JESJCL        JES2                         HELD
 JESYSMSG  JES2                          HELD
 CMPLOG     CCSSTART   STEP1    HELD
 DDPRINT    CCSSTART STEP1    HELD
 CMPRINT    CCSSTART STEP1    HELD
 CMPLOG     SRA03301 STEP1    HELD
 DDPRINT    SRA03301 STEP1    HELD
 CMPRINT   SRA03301 STEP1    HELD
 CMPLOG   SRA03302 STEP1    HELD


I want to delete all these JESMSGLG, JESJCL
JESYSMSG, DDPRINT, CMPLOG using REXX.

>>> required output

DDname Stepname Procstep Status

CMPRINT CCSSTART STEP1 HELD
CMPRINT SRA03301 STEP1 HELD


I used below logic. To detect particular ddnames in a job. But I’m not able to delete them.
That’s giving error at ADDRESS TSO FREE F(ISFIN) DDN(STEPN.J)

As a minimum, this
Select all
ADDRESS SDSF "ISFEXEC ST"
needs to be
Select all
ADDRESS SDSF "ISFEXEC H"

You cannot free datasets, you can only purge them, and that can only be done from the "Held Output" panel.

Thanks a lot for your quick reply. i'm done with the changes suggested by you.
could you advise me through which command in REXX I can accomplish this purging.

i tried this
ELSE DO
ADDRESS 'TSO' PURGE DDNAME.J

instead of
ADDRESS TSO FREE F(ISFIN) DDN(STEPN.J)
But Its abending with RC code 3. then which is the command?!

* * * * * * * * * * * ** * * * * * * * * * ** *
SYSPRINT IDCAMSF
IKJ56500I COMMAND PURGE NOT FOUND
56 *-* ADDRESS 'TSO' PURGE DDNAME.J
+++ RC(-3) +++
XXX --->>> DELETED

* * * * * * * * * ** * * * ** * * ** * * ** * * ** * * ** * *

You do not want to issue commands to the TSO environment, you want to issue commands to the SDSF environment, using "ADDRESS SDSF".

We do not use SDSF at my site, so I don't have a link to the SDSF documentation handy, but I've no doubt that many here can provide you with one.

(ETA: I found a link. What you do with it is your concern.)

It provided me a great information. :) i was working on it from many days and miracle happened in one day, that to i'm a beginner in REXX.
Finally i modeled my requirement and is working wonderful and this will be going to save lots of manual work in our team.

My many thanks to you Akatsukami.
