Hi all,

These days there are something confuse me a lot which happen in my CICS. It's about abend ARSA and SR0001. some incoming txn got ASRA abend and was written into the CICS log while abend SR0001 also occurs in the same time. By the setup in my cics, SR0001 will be written into the sysdump as well. everytime such case happened, the txn come from this channel will be blocked. My question is what's the affiliation between these 2 abends. why ASRA happen must cause SR0001. whether the channel block is due to the cics dump and sys dump to capture together? since from the log, I can see that sysdump is get 2-3 secs earlier than the cics dump.

here is the info from SYSDUMP:
CICS DUMP: SYSTEM=MYCICSA01 CODE=SR0001 ID=1/0017 310 11:31:11 01/12/09

I can see the ASRA is caused by getmain problem.

btw our sysdump buffer is defined as 2000M.

Hope some specialist could give me your advsie! Thanks so much!

since writing to logs in CICS is a queued service,
I would not try to read to much into the timing of the entries.

Have you used the information of the DFHSR0001 message to start to debug the problem?
DFHSR0001 applid An abend (code aaa/bbbb) has occurred at offset X'offset' in program progname.
What is the 'aaa' code?

Walk the transaction through CEDF and use PF9 to define stop conditions (stop at all CICS GETMAIN commands). I believe you'll find that the LENGTH/FLENGTH associated with this problem GETMAIN is ZERO.
