Hi,

I am trying to execute a jcl which takes the backup of IMSDB, but I am getting an error as mentioned below.

jcl:
Code:
//JS010    EXEC PGM=DFSRRC00,REGION=1024K,COND=(4,LT),

Getting below error:
Code:
+DFS671I A04124TA.JS010. - FOR THIS EXECUTION, DBRC IS SET TO YES    STG1     
+DSP0245I  JOB TERMINATED DUE TO UNAVAILABLE RECON DATA SETS

IEA995I SYMPTOM DUMP OUTPUT  116                                               


I tried giving all the datasets necessary for IMSDB backup, but still am getting this error. Could you please help me if I have missed any dataset concatenation ?. [/code]

Recon datasets are those datasets that needs to setup in any region by IMS DBA. Please check with IMS DBA of your org for missing recon datasets, they might help you in restoring the missing datasets which might solve your issue.

As mentioned by enrico in previous post check the action message from the log to understand more about the error.

Hi,

As mentioned by enrico, I have already researched on that abend and here are my findings,

Code:
DSP0245I                                               
                                                       
 JOB TERMINATED DUE TO UNAVAILABLE RECON DATA SETS     
                                                       
 Explanation                                           
 ~~~~~~~~~~~                                           
 DBRC was unable to locate any RECON data set.         
                                                       
 System action                                         
 ~~~~~~~~~~~~~                                         
 The job is terminated.                                 
                                                       
 User response                                         
 ~~~~~~~~~~~~~                                         
 Define RECON data sets, and rerun the job.             
                                                       
 Problem determination                                 
 ~~~~~~~~~~~~~~~~~~~~~                                 
 None.                                                 
                                                       
 Last updated: October, 2009                           



I am aware that RECON datasets will hold the log information in IMS and DBRC is an utility that runs in IMS environment used to take backup of IMS database, but I thought the log datasets mentioned in the jcl will take care of.

So is there a way I could resolve it by giving any missing datasets/parameters along with "PARM='ULU,DFSUDMP0'" OR should I only contact DBA.

Please help.

Why not just contact the DBA. This is the sort of thing that he is paid for.

My bet is that the Job submitter does not have proper security (racf , acf2) access to create the backup tapes.

Check the JESMSGLG out from your job.

What you shown is informational message , you needed to check JESMSGLG as suggested above to know the exact reason.

did anybody care to look at the initial post and meditate on the message sequence before answering

Code:
+DFS671I A04124TA.JS010. - FOR THIS EXECUTION, DBRC IS SET TO YES    STG1     
+DSP0245I  JOB TERMINATED DUE TO UNAVAILABLE RECON DATA SETS                   
+DFS0048I DBRC INITIALIZATION FAILED -  RC=16 STG1       


looks like not, by looking at the advices given ...

the first message DFS671I
tells that the user has chosen to run with the recovery control feature activated
the second message DSP0245I
tells that because of the above the RECON related ( REcovery CONtrol ) ddname(s) is/are REQUIRED

since the user written jcl DOES not contain the RECON related dd statements
the job fails

the only way to solve the problem is to talk to the DB support group to ...
1) find out if the organization practices allow to take a backup/image copy outside of the recovery control environment
and disable the same in the parms
2) if 1 is not true ask the DB support group to amend the jcl with the proper ddnames

the messages are not informational ... THE JOB FAILS
no racf concerns... the job would have abended with different symptoms

AMEN

Hi,

I tried to give the RECON data sets, it showed me insufficient access authority.
I got an error telling, INTENT (UPDATE) ACCESS (READ), even though I am only taking backup.

So i thought it might be because of the DB being running. So I stopped the DB and then executed it in DLI mode. But even then I got the same access authority error telling that my intent is to UPDATE the DB rather than reading.

Could you please assist. I do also have a plan to discuss with DBA.

NO we will not assist, the problem must be solved by your DBA,
planning to ask is not enough.
