•
Yes, the attach is local.
•
No, the TP is not dispatched.
All reply and return codes have the value zero (0), a normal completion. Because all
the other verbs issued by this TP complete normally, those subsequent responses
have been edited out from the rest of the example.
The TP uses the ALLOCATE verb to establish a conversation with the remote TP.
ALLOCATE should be the first verb issued after a TP has locally attached itself to
the SNAX/APC process (using a LOCAL TP-READY request).
The parameters of the verb indicate:
•
The partner LU name is lup01.
•
The partner TP name is progp01a001.
•
The mode is left blank, which represents a default name.
•
The conversation type is Basic.
•
The synchronization type is Confirm.
The local TP moves data into the SNAX/APC send buffer by using SEND-DATA.
Using this verb does not necessarily cause the data to be transmitted immediately.
Subsequent SEND-DATA verbs cause the new data to be concatenated with the data
already in the send buffer. The data is sent to the remote TP when the send buffer
overflows or when SNAX/APC receives a verb from the local TP that explicitly
causes the data to be transmitted (flushes the send buffer); in this case the verb is
CONFIRM.
The parameters of the verb indicate:
•
The decimal length in bytes of data to be sent.
•
The hexadecimal length of the GDS variable.
•
The GDS variable type in hexadecimal.
•
The data, represented as a string of characters enclosed in quote signs.
The local TP issues a CONFIRM verb. The CONFIRM verb requests confirmation
of receipt of data or completion of some function. This verb flushes the buffer of
data waiting to be sent (sending the data to the remote TP) and requests an explicit
confirmation from the remote TP when it has received the data. CONFIRM
terminates when SNAX/APC receives a confirmation or error reply from the remote
TP.
The local TP issues the DEALLOCATE verb with the FLUSH parameter, to flush
the transmission buffer and terminate the conversation normally. The TP must be in
the Send state to issue a DEALLOCATE FLUSH verb request. DEALLOCATE
FLUSH terminates when the SNAX/APC internal buffer has been flushed and the
local resources have been deallocated.
