COMMTASK diagnosis methods
COMMTASK provides several diagnostic functions to view the following
information in dumps:
- Messages in the wait state message area.
- Branch entry messages on the delayed message queue.
- Message suppressed during nucleus initialization program (NIP) processing.
You can view messages in the wait state message area with the following
IPCS functions:
- The STATUS WORKSHEET subcommand or option 2.3 (WORKSHEET) of the
IPCS dialog gives central processor information. One section of this
report provides the formatted wait state message area. The following
is an example of formatted wait state message area for an X'A2B' wait
state as it appears in the IPCS report:
Wait State Message Issued at 08:40:10 on Day 255 of 1989: IGF912W EXTENDED STORAGE FAILURE, RE-IPL THE SYSTEM
- The CBFORMAT WSMA subcommand formats the wait state message area and produces a report similar to the preceding example.
