Hi,
I have a problem where I have to deal with huge volumes of data. When we transmit that file to Windows, the size comes to 32 GB. When we try to process this file through a job (With CLASS=A), The job executes successfully once, but not if it is re-executed in five minutes. It ABENDs with an SB37 code. (Volume end). We have tried freeing up GBs of space, but we still get the same error.
Analysis of the spool shows that in each case, a different initiator chose the job. When it ran successfully under CLASS=A, INIT 14 picked it up and gave MAXCC=0. But whenever any other Initiator gets involved, for the same CLASS, I get SB37 ABEND.
Is there any way to specify which initiator I want to take my job? I wish to specify that even if Initiator 6 becomes available, my job should work just for Initiator 14, CLASS=A. Is it even possible to do that?
Thanks.
Wilson... |

What does your JCL manual say about specifying a particular initiator? Why do you think a particular initiator would get rid of a B37? All initiators access the same DASD. The lack of free space is your problem. Chopping and changing initiators will do nothing as they all access the same lack of DASD and doing this may well put you in breach of site standards as to which class to use for what type of job. The people to see are your storage guys.
By the way, in terms of JCL there is no such thing as MAXCC - that is an IDCAMS internal term ONLY. You should refer to 'maximum, or highest, return code' |

OK, let me clarify:
1. Space is no longer a problem - I have freed up Gigabytes of space by deleting some useless files.
2. For the same class A, different initiators can be called up. This is not guesswork, but based on analysis of spool.
3. INIT 6 Throws SB37 for that job, while INIT 14 does not. I don't know the details as to why, but I do know what I'm seeing.
Nic, I appreciate you trying to point out errors in the way I asked the question, but bear in mind that I'm asking this only after due analysis, and also because I hoped someone else might have faced the same issue before. The answer you gave was very enthusiastic, but ultimately, poorly informed and highly unhelpful.
Still looking for answers.

suggest that this thread be locked
and TS referred to students/rookie forum,
since the TS refuses to read the manuals,
and attempt to understand how z/os computers work.
as evidenced by the comments,
the TS has more interest in having her/his opinion validated,
instead of learning/thinking/reading.
either that or we all chip-in so that the TS can get the
'window in the stomach' operation that s/he so needs,
so that the TS can see where s/he is going. |

A bit patronizing/pedantic aren't you?
Nic told you what you are saying, and beside that analysis of spool to find out which initiators are assigned to job classes is stupid, there are JES2 commands to get that info. Then there is the chance that when your job was running in initiator 6 no space was available at that moment and after rerun in initiator 14 space was available. |

The question is simple: Is it possible to assign a specific initiator to our JCL? Nothing more. I have already resolved my issue and completed the job.
A Yes or No answer would have sufficed.
And dbzTHEdinosauer, you are a respected member of this forum. I was honestly looking for an answer that answered just my question, and answered it straight. Not one that's dripping with hostility.
Thanks.

I apologize if I appeared patrionizing. But I honestly got nothing useful out of Nic. Everytime INIT 14 was engaged, the job was successful. Without exception. Any other Initiator gave an error. I was just trying to understand if there was a way to fix that, and then understand what happened to cause that SB37 issue, even after freeing up GBs of data. |

Vivek,
Forget your pre-conception, until you have done each thing which Nic suggested.
Ask your storage people what you asked here. Then forget it for ever, and anything similar which you might come up with (you seem to have something of a record from your posts). |

On behalf of enrico:
IIRC
Nostradamus Centuries/Prophecies forecasted such terrible event
quite awkward latin wording, for the lack at those times of proper IT latin words
along with terrible mishaps for all initiators except 14
unfortunately He was very <foggy> about installations with less than 14 initiators ...

Hi Nic,
My apologies. You had been right after all. Looks like an unauthorized user was running a few jobs that took up all the GBs of free space I created, and because of that SB37 was being thrown up. Sorry if I appeared snooty that day.
Thanks.

Nice to know the problem is gone. Good to see you have grace, Wilson. |
