You can use NOSIGNONWAIT to start
multiple server sessions in parallel. Parallelism reduces the total
amount of time that would be used to start individual connections
to server sessions. This time savings allows the client session to
do other processing, such as submitting units of work remotely to
a server session, as soon as sign-on is complete.
If NOSIGNONWAIT
is specified, you might also want to specify the CMACVAR= option in
the SIGNON statement. Setting CMACVAR= enables you to learn the status
of the current asynchronous SIGNON (whether it has completed or is
still in progress).
In addition
to being a system option, SIGNONWAIT can be set as an option in the
RSUBMIT and SIGNON statements. The option in the RSUBMIT or SIGNON
statement or command takes precedence over the system option.
