Use the ABEND keyword to document a problem when CICS® VR abends
with a system abend.
The failing module can be one of these:
- A CICS VR module
- A CICS VR exit
- A module of another IBM® licensed program running in the CICS VR address
space
CICS VR usually
produces a system dump for an abend. If no dump is produced, the dump file
might be full, in which case you must re-create the abend with a larger dump
file. Check for error messages that occurred while
CICS VR was
trying to produce a dump. A symptom string in the dump provides information
about what was happening at the time of the abend.
Follow this procedure to produce a system dump:
- Allocate the SYSMDUMP ddname to a data set with these data control block
(DCB) parameters. The DCB for SYSMDUMP can vary for different versions of MVS™:
- The dump data must be stored on a data set with sequential (PS) organization.
- The logical record length (LRECL) must be 4160 bytes.
- The data set must have one of these combinations of record format (RECFM)
and block size (BLKSIZE):
- RECFM=F,BLKSIZE=4160
- RECFM=FB,BLKSIZE=n×4160 where n=1,2,...
- RECFM=FBS,BLKSIZE=n×4160 where n=1,2,...
If the data set meets these criteria, the Interactive Problem Control
System (IPCS) provides special purpose processing. In special purpose processing,
IPCS simulates system services, such as dynamic address translation and control
block formatting, when processing the information source.
- If the abend occurred in the CICS VR ISPF dialog interface:
- Allocate the SYSMDUMP data set with DISP=MOD. (If CICS VR abends
before ISPF, both write to the SYSMDUMP data set. If you use DISP=SHR, you
can see only the ISPF dump.
- Set the ISPF options in the ISPF ENVIRON COMMAND SETTINGS window (option
0.7):
ENBLDUMP=ON
- Specify that you want to receive all write-to-programmer messages (including
the message ID), at your terminal. To do this, enter this TSO/E command:
PROFILE WTPMSG MSGID
- Re-create the abend and record any messages.
After ISPF is terminated,
at the TSO/E prompt:
READY
press Enter, and a dump
is produced. Do not press any other key than Enter.
