Formatting RTM Dump Data

To format RTM control blocks in an SVC dump or a stand-alone dump, enter the IPCS SUMMARY FORMAT subcommand. The control blocks are all TCB-related, and are formatted only when they are associated with the TCB. The formatted control blocks are:

• FRRS (functional recovery routine stack) - points to the RT1W and is formatted with the current TCB if the local lock is held.
• IHSA (interrupt handler save area) - has the normal FRR stack saved within it and is formatted with the TCB pointed to by the IHSA, if the address space was interrupted or suspended while the TCB was holding the local lock.
• RTM2WA (RTM2 work area) - formatted if the TCB pointer to it is not zero.
• ESA (extended save area of the SVRB) bit summary - formatted only if the RTM2WA formatted successfully and the related SVRB could be located.
• SDWA (system diagnostic work area) - formats the registers at the time of error only if the ESA formatted successfully and the SDWA could be located.
• EED (extended error descriptor block) - formatted if the TCB or RT1W pointer to it is not zero.
• SCB (STAE control block) - formatted for abend tasks only. It is formatted under SNAP/ABEND whenever the TCB pointer to it is not zero.
• XSB (extended status block) - formatted if the XSB pointer in the IHSA is not zero.
• STKE (stack element) - formatted if the STKE pointer in the XSB is not zero.
