Diagnosing IMSplex problems

Each of the Common Service Layer address spaces, OM, RM, and SCI, produces SDUMPs for internal errors. You can find the CSL dumps in the SYS1.DUMP data sets.

To successfully diagnose IMSplex problems, you might need to collect one or more of the following types of system information:

• The SYSLOG from every logical partition (LPAR) where a CSL member resides.
• Output from the type-2 QUERY command to display the members of the IMSplex and their status.
• A z/OS® SVC dump of the CSL address spaces.

You can write OM log records to a z/OS Logger data stream by specifying the AUDITLOG= parameter of the IMSPLEX keyword on the CSLOIxxx PROCLIB member data set. The log records provide an audit trail of command input, associated command output, and unsolicited message output.

You can view the messages in the audit trail using the TSO SPOC. Use the action bar to select SPOC > Audit Trail and fill in the data stream name and the time of interest.
