COMCHECK SBC subcommand output

The COMCHECK SBC option formats information from the supplemental branch entry console (SBC) control block.

The SBC contains information about the delayed issue queue. The queue contains messages and delete operator message (DOM) requests issued by system initialization and branch-entry WTO/WTOR/DOM processing in programs that run when a Supervisor Call (SVC) instruction cannot be issued or require the request to be handled synchronously. The system issues requests on the delayed issue queue as SVC requests.

The following is an example of a COMCHECK SBC report:

The following field appears in the report:
DELAYED ISSUE QUEUE BROKEN
One of the following:
YES
The delayed issue queue is valid.
NO
The delayed issue queue is not valid.
DELAYED ISSUE QUEUE FULL
One of the following:
YES
The delayed issue queue is full. The delayed issue task can free up space on the queue during normal processing, or a different program can obtain space for additional entries. If the condition persists, the queue may not be valid.
NO
The delayed issue queue is not full.
DELAYED ISSUE TASK IS PROCESSING DELAYED ISSUE QUEUE
One of the following:
YES
The delayed issue task is actively processing entries on the delayed issue queue.
NO
The delayed issue task is not actively processing entries on the delayed issue queue.
DELAYED ISSUE SRB CAN BE SCHEDULED
One of the following:
YES
The service request block (SRB) routine for the delayed issue task is initialized and can be scheduled.
NO
The routine has not been initialized or has abended.
NIP WTO/WTOR/DOM PROCESSING ACTIVE
One of the following:
YES
The system initialization service that processes WTO, WTOR and DOM requests is active.
NO
The system initialization WTO/WTOR/DOM service is not active. One of the following occurred:
  • The dump was taken early in system initialization, before the service was initialized.
  • The dump was taken after COMMTASK started handling WTO, WTOR, and DOM requests.
NUMBER OF ACTION/WTOR MESSAGES NOT LOGGED
The number of:
  • WTO messages requiring operator action
  • WTOR messages that could not be logged on SYSLOG, because the system was unable to add the message to the delayed issue queue
TOTAL NUMBER OF MESSAGES NOT LOGGED
The total number of WTO and WTOR messages not logged on SYSLOG. The system was unable to log the messages because they could not be added to the delayed issue queue.
TOTAL NUMBER OF SYNCHRONOUS MESSAGES NOT DISPLAYED
The total number of synchronous WTO and WTOR messages not displayed. They were not displayed because WTO/WTOR processing was unable to display them on a console with master authority.
NUMBER OF NIP MESSAGES ON THE DELAYED ISSUE QUEUE
The number of messages on the delayed issue queue that were issued during system initialization.
TOTAL NUMBER OF MESSAGES ON THE DELAYED ISSUE QUEUE
The total number of messages on the delayed issue queue.
NUMBER OF NIP DOM REQUESTS ON THE DELAYED ISSUE QUEUE
The number of DOM requests on the delayed issue queue that were made during system initialization.
TOTAL NUMBER OF DOM REQUESTS ON THE DELAYED ISSUE QUEUE
The total number of DOM requests on the delayed issue queue.
INFORMATIONAL MESSAGES SUPPRESSED DURING NIP
One of the following:
YES
Informational messages are suppressed during system initialization. The system sends the messages to SYSLOG.
NO
Informational messages are not suppressed during system initialization. The system displays the messages on the console.
NUMBER OF INFORMATIONAL MESSAGES SUPPRESSED DURING NIP
The total number of informational messages suppressed during system initialization. If informational messages are not suppressed during NIP processing, this field contains zero.
TOTAL NUMBER OF BWJE REQUESTS ON THE DELAYED ISSUE QUEUE
The number of job-end requests on the delayed issue queue.
