Explicit-mode client call sequence z/OS Communications Server: IP IMS Sockets Guide SC27-3653-00 |
|
The call sequence to be used by an explicit-mode client program is:
1 If the Listener
is unable to initiate the transaction, it sends a request-status message
(RSM) to the client indicating the reason for failure. Therefore,
the client must be prepared to receive that message. It is suggested
that a convention be established that the server initiate the conversation
by sending an opening message. By following this convention, the client
will receive either positive or negative notification of transaction
status before initiating application data exchange.
