An SYSUDUMP usually does not provide adequate information for problem investigation, therefore an SVC Dump is needed to address abnormal conditions.
Perform the following procedure to generate an SVC Dump when an abnormal condition is triggered.
1. At the system console issues the following command:
DUMP COMM=(users comment)
2. The system responds with the following:
xx IEE094d SPECIFY OPERANDS(S) FOR DUMP COMMAND
where xx is the reply number.
3. Reply to the console message with:
xxJOBNAME=(aaaaaaaa),SDATA=(RGN,CSA,TRT)
where:
xx is the reply number
aaaaaaaa is the TPX procedure name
RGN is the region of the address spaces
CSA is the Common Service Area
TRT is the Trace table entries
4. If CA-TPX is running as a Generic Resource, add the following to the previous console reply:
,STRLIST=(STRNAME=coupling facility structure name,
ACCESSTIME=NOLIMIT,
LOCKENTRIES,
(LISTNUM=ALL,
ADJUNCT=CAPTURE,
ENTRYDATA=SERIALIZE))
5. The system responds as follows:
COMPLETE DUMP ON SYS1.xxxxxx
6. The following system response indicates that the dump is incomplete and the dump dataset is too small:
PARTIAL DUMP ON SYS1.xxxx
Increase the size of the dump datasets and try again.
Open a new CASE and FTP the SVC Dump to Broadcom Technical Support, in tersed format, along with the corresponding TPX started task log.
Refer to the IBM z/OS MVS System Commands documentation for detail on the commands.
