Hi,
I have developed a REXX code which searches a given 10 strings for maximum and returns the output in a PS file.
Now as my REXX tool is working fine my requirement here is that im facing a hang problem as the whole time is been laid down for the REXX searching when this TOOL is triggered.
say suppose the strings which to search are from the PRDN libraries so it is taking more than half an hour,so facing the efficiency problems.
Is there any way that i trigger the tool and it processes in the background and get displayed once the whole search is done.so the person can be able to carry on with his prior work.
If not the REXX gets submitted and Passes on to JCL and then after the MAXCC >= 4 then the PS file gets with the desired result. |

To clarify the terminology here, background is a submitted job.
And can that submitted job suddenly interact with your TSO session and show results - NO
This has been discussed many times and the answer never seems to change. There is a search facility on the forum. |

IRXJCL can be a way to go but NOTE IRXJCL does not permit the full functionality of IKJEFT01, so if your REXX uses TSO commands such as ALLOCATE etc. they will fail.

For what did you post this? What information does this convery? If possible, please rephrase this and post back again if it's relevant to what you are asking. |

Ok ,
can we have the rexx job submitted then completely taken over by JCL program and then when the job submits we can go check in the SPOOL.
like
| Code: |
REXX SUBMIT----->>>>TAKEN OVER BY JCL---->>>CHECK IN SPOOL

JCL is not a program - it's just JCL. And what you post does not help us to provide you something helpful - what you post with BBcode is just a DISPLAY and you can display whatever you want.
Probably you've written some edit macro and want to execute it from command line, do you? And that macro should do the "stuff" in background?If so, you might write a small macro which will in turn call your "main REXX"... just a thought ... |

you can certainly submit any rexx program to run in batch. No problem there. There may, however, be a problem with the algoritm or implementation.
If you are searching all data sets that start, for example, with PRDN, then you might be causing the last reference date to be updated for a very large number of data sets which could cause your storage management system to not be able to move unused datasets off line (to archive, tape, backup, whatever).
The second issue is using Rexx (and presumably EXECIO) alone to do the search. Rexx is pretty slow for this type of thing so you may be using system resources (CPU and I/O) inefficiently. I would suggest calling SORT or SuperC (ISRSUPC) to do the searching and to limit the search to only the data sets you actually care about. You can call SORT or SuperC from Rexx and parse the output using EXECIO. |
