Distributed FileManager/MVS detects four types of communication
errors:
- A SEND ERROR was issued by the source. Distributed FileManager/MVS
stops all processing in the conversation, but processing does not
terminate.
- APPC/MVS returns an unexpected error return code. Distributed
FileManager/MVS logs the error into the system LOGREC file and terminates
the conversation.
- APPC/MVS returns an error code that indicates a system logic error
in Distributed FileManager/MVS. See System logic errors for
a description of processing in this case.
- APPC/MVS indicates a DEALLOCATE ABEND of the source system. Distributed
FileManager/MVS performs no error recording; it simply terminates
the conversation.
If a source system attempts to communicate with an MVS system that
has the Distributed FileManager/MVS installed but not active, an AGNPRMRM
reply message with error code X'0021' (see Distributed FileManager/MVS general error codes) is returned to the source system.
