A Messages
This appendix lists the following types of messages that can be
returned by the APPC subsystem:
• Subsystem startup messages, returned to the terminal from which
an APPCCONTROL START command is issued.
• Logging messages, which are returned to the system console, to a
disk file, or to a user terminal, depending upon configuration.
• Error messages, which are returned to the terminal from which an
APPCCONTROL command is issued. (The types of messages logged
depend upon the logging classes that have been configured.)
• Warning messages, which are returned to the terminal from which
an APPCCONTROL command is issued.
• Return codes, which are returned by control operator intrinsics to
the TPs that call them.
• Configuration validation messages, which can be returned by
NMMGR when you validate the configuration file.
After each message in this appendix is a short description of the
possible causes of the message and the actions that each message
indicates you should take.
