The system does the following:

  3. Makes the trace records available in the dump, if a trace was active for APPC
  4. Issues message ASB050I after issuing the first abend
  5. Does not process the work sent to the APPC/MVS transaction scheduler
  6. Issues message ASB053I when the APPC/MVS transaction scheduler ends.

Operator response

Enter the START ASCH command to start a new APPC/MVS transaction scheduler. See z/OS MVS System Commands for details on starting the APPC/MVS transaction scheduler. If the problem recurs, notify the system programmer.

System programmer response
