You must collect diagnostic information for problems that occur
using the CICS® VR
server address space, either when starting the CICS VR server address space or when initializing
the CICS VR
server address space at IPL.
Problems starting the CICS VR server address space
If
you experience a problem starting the CICS VR server address space or a service
of the CICS VR
server address space, send the IBM® Support Center a copy of these logs
and data sets.
- SYSLOG
- The system log (SYSLOG) is a SYSOUT data set provided by the job entry
subsystem (either JES2 or JES3). SYSOUT data sets are output spool data sets
that reside on direct access storage devices. Most installations print the
system log periodically.
The system log contains these messages:
- Messages that are issued through WTL macros
- Messages that are entered by operator LOG commands
- Messages that are routed to the system log from any system component or
program
- DWWMSG data set
- If the CICS VR
server address space encounters certain error conditions, CICS VR writes
error messages to the data set allocated to the DWWMSG ddname.
- DWWDUMP data set
- If the CICS VR
server address space encounters an unexpected abend, CICS VR writes diagnostic and tracing information
to the data set that is allocated to the DWWDUMP ddname (if a data set has
been allocated).
- DWWDMSG data set
- If the CICS VR
server address space encounters an unexpected abend, CICS VR writes a trace table of prologs
and epilogs of the latest called modules to the data set that is allocated
to the DWWDMSG ddname (if a data set has been allocated).
- RCDS
- To learn how to create a sequential data set copy of the RCDS, see Creating a sequential data set copy of the RCDS.
For the CICS VR server address space, the data
sets allocated to the DWWMSG, DWWDUMP, and DWWDMSG ddnames have the following
naming convention: hlq.slq.DWWMSG | DWWDUMP | DWWDMSG.systemname.
Exception: The data set naming convention changes if the first
character of systemname is a number. For more information about data
set naming conventions, see Allocating data sets required by the CICS VR server address space.
Problems initializing the CICS VR server address space at IPL
Perform
these two steps to collect diagnostic information if you experience a problem
initializing the CICS VR server address space when you IPL your system.
- After the IPL initialization is complete, issue the following commands
and record the results:
- D SMS,CICS VR
- V SMS,CICS VR,ACTIVE
- SETSMS CICS VR_INIT(YES)
- D SMS,CICS VR
- V SMS,CICS VR,ACTIVE
- D SMS,CICS VR
- Send the output from these commands and a copy of the SYSLOG to the IBM Support
Center.
