Use the information presented below to identify a potential system wait or loop. Then contact the IBM® Support Center for assistance with analyzing the dump.
If the system does not issue a message, the system could be waiting or looping.
SDATA=(TRT,LPA,CSA,PSA,GRSQ,SUM,SQA,ALLNUC,LSQA,RGN,SWA)
Refer to z/OS MVS System Commands for information on how to generate a dump.
After producing a dump, use IEBGENER to copy the SYS1.LOGREC data set to a standard label tape. This data set contains the event history leading up to the wait problem.
Recommendation: If you have the DFSORT product installed, you should be using ICEGENER as an alternative to IEBGENER when making an unedited copy of a data set or member. It might already be installed in your system under the name IEBGENER. It generally provides better performance.
