DISPATCHER-READY Verb
DISPATCHER-READY Verb
The SNAX/APC Dispatcher sends a DISPATCHER-READY request to the SNAX/APC
process when the Dispatcher is first initialized; the DISPATCHER-READY request is
queued.
The SNAX/APC process sends a DISPATCHER-READY reply to the Dispatcher when
the following is true:
•
The SNAX/APC process receives an ATTACH request from a remote TP.
•
A DISPATCHER-READY request is already waiting on the DISPATCHER-READY
queue.
•
The requested TP is not already waiting for a conversation (that is, has not issued
TP-READY).
The DISPATCHER-READY reply contains information about the requested local TP.
If the ATTACH request is queued before the SNAX/APC process receives the
DISPATCHER-READY request, the ATTACH request completes as soon as the
SNAX/APC process receives the DISPATCHER-READY request.
Note. A TP never sends or receives the DISPATCHER-READY request. However, the
DISPATCHER-READY request and reply messages appear in the SNAX/APC trace
files; thus, the request is shown here to facilitate debugging.
