Deactivates the APPC subsystem and all active APPC sessions. Syntax | |
I32 I16V
APPCStop (ReturnCode [,StopType]) |
Parameters | |
- ReturnCode
Required. 32-bit signed integer;
output. Indicates the result of the intrinsic execution. The
ReturnCode consists of two 16-bit fields: an information field, containing
the number of an APPC warning or error message, and a subsystem
field, containing the number of the subsystem that generated the
message. If both fields contain zeros, the intrinsic executed successfully, and
there are no messages. For more information, see "Return
Codes" at the beginning of this chapter. Appendix A “Messages” contains a list of all return codes returned by the
APPC subsystem, their causes, and the actions you should take to
resolve any problems. - StopType
Optional. 16-bit signed integer;
input. Specifies the type of subsystem shutdown (Kill, Protocol,
or Quiesce). Allowable values are as follows: - 1
Kill. All active sessions
will be terminated immediately. Conversations using the sessions
will not be allowed to complete. TPs will not be terminated, so
users must terminate their TP processes when the subsystem goes down. - 2
Protocol. All active sessions
will be terminated, pending notification of any transaction programs
currently in conversation. Once the active TPs have been notified,
their sessions will be terminated. TPs will not be terminated. - 3
Quiesce. Orderly shutdown
of the APPC subsystem, allowing all current conversations to be
completed but preventing any new conversations from being allocated.
No APPC session will be brought down until the conversation using
it has been deallocated. When the conversation has completed, the session
will be terminated. TPs will not be terminated.
Default: 3 (Quiesce)
