I did see this APAR that could affect performance: PK21373 It is still open.
Thanks.

Your comment about it seeming to be load related and the fact that TSO response time did not change points me in that direction. Just a thought. Christopher Y. Blaicher BMC Software, Inc.

I know this is a vague email, but has anyone else seen anything like this with z/OS 1.7? Also, we did not really see a spike in TSO response time, so it seemed to be CICS and IDMS related. I was just wondering if there was some major change in VTAM or TCP/IP code that could have affected back level online applications like our IDMS (release 16.) and CICS TS (release 1.3)? As I said, I have searched the archives and the CICS, IDMS, and z/OS 1.7 fix databases and found nothing that seemed to be a direct match. Also, this problem does not seem to occur on our test system, as we have tried to recreate it there. So we are also suspicious of it being load related. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
