Formatting coupling facility structure dump data using the IPCS subcommand - STRDATA

If you are having a problem with a structure, the STRDATA subcommand of IPCS provides information about structures. Format the SVC dump with the IPCS STRDATA subcommand to produce diagnostic reports about coupling facility structures. z/OS MVS IPCS Commands gives the syntax of the STRDATA subcommand.

The dump may also contain component trace data for XES. See the component trace chapter of z/OS MVS Diagnosis: Tools and Service Aids for information on how to format this trace data.

STRDATA can result in many different reports depending on which keywords you use. Table 1 lists the possible reports and the STRDATA keywords to specify to get them. In many cases, a report may be generated by several keywords. The STRDATA ALL STRUCTURES DETAIL REPORT and the STRDATA ALL STRUCTURES SUMMARY REPORT are generated with almost every invocation of the STRDATA subcommand.

Note:

There is no exception report for the STRDATA subcommand.
All report examples have been compressed and repetitive information has been pared down for this document. Therefore, the examples look slightly different from the way they look on your system.
