Return codes
UERCAQUE
Queue the request. This is the default.
UERCAPUR
Do not queue the request, unless local queuing is possible.
XPI calls
All can be used.
Important
There is no ‘UERCNORM’ return code at this exit point, because the exit is invoked
after a failure. The choice is whether or not to take the system default action of
queuing the request.
The XISLCLQ exit
XISLCLQ enables you to specify what action to take after a function shipping
request fails to allocate a session with a remote system for one of the following
reasons:
v The remote system is not in service.
v A connection to the remote system cannot be established.
v No sessions are immediately available, and your XISCONA exit program has
specified that the request is not to be queued in the issuing region.
