The following IPCS subcommands can help you diagnose errors in an address space that owns subspaces:

• The RSMDATA subcommand allows you to produce a subspace report.
• The STATUS subcommand with the FAILDATA option includes the subspace environment at the time of error.
• The NAME subcommand displays the subspace name and address space identifier when the STOKEN specified is a subspace STOKEN.
• The SUMMARY subcommand with the FORMAT keyword generates a report that indicates whether a program was running in a subspace when the error occurred.
• The VERBEXIT subcommand with the LOGDATA verb name formats LOGREC buffer records that indicate whether a program was running in a subspace when the error occurred and, if so, include the subspace name and STOKEN.
