Taking a dump of CICS® IA

For certain types of problem, you might be asked to supply a dump of CICS® IA. To request a dump of a CICS® IA address space and its associated data space, use the MVS DUMP command.

You can issue the MVS DUMP command from the console. Use the ASID= keyword to identify the address space and the DSPNAME= keyword to identify the data space.

The data space name takes the form nnnnnINT, where nnnnn is a five-character number that can be obtained from the CICS® IA Operations Statistics Menu, CIU150, shown in Collector Statistics Menu panel, CIU150, showing the CICS IA data space name. It is usually 00000INT.

To obtain the data space name for the CICS® address space in which CICS® IA is active, use the MVS DISPLAY ACTIVE command: 
/D A,cicsname
where cicsname is the name of the CICS® address space.
Example output from an MVS DISPLAY ACTIVE command, showing a data space name of 00000INT shows some example output from the MVS DISPLAY ACTIVE command. In this example, the cicsname is CICSTS0A, the ASID is 00A8 and the data space name is 00000INT. The data space name is also available from the CICS® IA Operations Statistics Menu. In the following examples a dump for CICS® region CICSTS0A has been taken, where CICSTS0A is the name of the CICS® address space. The CICS® applid for this region is IYCYZC3A and the CICS® sysid is TS0A.

To dump this data space, use the following command, where nn and mm are the outstanding reply numbers: 
/DUMP COMM=(IA DUMP) 
/R nn,JOBNAME=CICSTS0A,CONT 
/R mm,DSPNAME=('CICSTS0A'.00000INT),END

Formatting the CICS® IA Dump

If you use the MVS interactive problem control system (IPCS) to format and analyze CICS® system dumps, you can use the CICS® IA system dump formatting routine to format the CICS® IA Collector data areas and trace, the dump formatting routine accessible to IPCS, as described in CICS IA supplied modules required in the MVS link list. When your CICS® system dump is formatted by the CICS® release-dependent formatting routine, the CICS® IA Collector data areas and trace are also formatted under the heading CICS® Interdependency Analyzer Control Blocks.

Use the IPCS command: 
IPCS VERBX DFHPDnnn 'ft'
where nnn is the CISC TS version; for example DFHPD650. This command invokes the feature table and routine for a CICS® TS dump. The CICS® IA feature routines are called CIUIADUF and CIUICDUF, and can be located in the output by searching on =CIUIADUF (or =CIUICDUF).
For example: 
 =CIUIADUF: Feature routine
