BPXP004E FORK PROCESSING FAILED. AN ERROR OCCURRED DURING APPC PROCESSING. APPC RETURN CODE = returncode. VERIFY THAT APPC AND APPC SCHEDULER ARE OPERATIVE.
Explanation
APPC/MVS™ reported an error during fork processing. The error may be caused by one or more of the following reasons:
- APPC/MVS is not operating.
- The APPC/MVS scheduler is not operating.
- The APPC/MVS scheduler is malfunctioning.
- APPC/MVS configuration work was not done correctly when z/OS UNIX was installed. The ASCHPMxx members may not have been updated to define the APPC/MVS scheduler class name used for z/OS UNIX, or the APPC/MVS scheduler may have been started with an incorrect member that does not have the class name.
In the message text:
- returncode
- The error return code from APPC/MVS. z/OS MVS Programming: Writing Transaction Programs for APPC/MVS provides more details on the APPC/MVS return code.
System action
The system requires APPC/MVS to be functioning in order to process fork requests.
Operator response
Contact the system programmer.
System programmer response
Verify that APPC/MVS is operating by issuing a DISPLAY APPC command. Verify that the APPC/MVS scheduler is operating by issuing a DISPLAY ASCH command. If the scheduler is operating, verify that it has been started correctly with the proper member name.
If this is the first time you are initializing z/OS UNIX, verify that the ASCHPMxx member has been updated to define the APPC/MVS scheduler class name used for z/OS UNIX.
