Had another hang today - 6 minutes 50 seconds. HMC SAD indicated 100% utilization in supervisor state.
RMF indicated the DB2xMSTR was the big CPU user. The DB2 test batch job was not canceled this time but rather completed rc=0 - just as the system came back. IBM asked for a dump (which has been sent), suggested an increase to TRACE (TRACE ST,3M) and asked for a dump to be taken as close to the next hang as possible. We considered Jim Mulder's suggestion of writing a small stimer program or using OPS/MVS - but decided to issue the DUMP command on the 'hung' console. When the system free's up - the dump will be taken. I've asked the programmer NOT submit the possible causing batch job until I can get the system in a more controlled environment this weekend. Thanks again for the suggestions. ---------------------------------------------------------------------- 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
