MC-PREPARE-TO-RECEIVE (SF4)
MC-PREPARE-TO-RECEIVE (SF4)
The MC-PREPARE-TO-RECEIVE verb changes the conversation from the Send state to
the Receive state in preparation to receive data. The local TP (APS) must be in the Send
state to issue this verb request.
Request Fields
Type (SL,FL,CO)
specifies the type of the MC-PREPARE-TO-RECEIVE request that you want to
perform. The different types are:
SL
specifies that the type of the MC-PREPARE-TO-RECEIVE request to be
performed is to be based on the synchronization level specified for this
conversation.
If the synchronization level is SYNCPT, the DEALLOCATE will be rejected. If
synchronization level is NONE (N), SNAX/APC transmits the contents of the
local LU’s send buffer to the partner TP and then places the conversation in the
Receive state. The MC-PREPARE-TO-RECEIVE verb completes as soon as the
local LU’s send buffer is transmitted; no confirmation is required. This is
functionally equivalent to an MC-PREPARE-TO-RECEIVE request with Type
set to FL (flush).
If synchronization level is CONFIRM (C), SNAX/APC transmits the contents of
the local LU’s send buffer to the partner TP and then requests confirmation from
the partner TP. The MC-PREPARE-TO-RECEIVE verb does not complete until
