-
SIGNONWAIT
-
specifies that a SAS/CONNECT SIGNON statement
will execute synchronously. Synchronous processing means
that a sign-on to a server session must complete before control is returned
to the client session.
-
NOSIGNONWAIT
-
specifies that a SAS/CONNECT SIGNON statement
will execute asynchronously. Asynchronous processing
permits sign-ons to multiple server sessions to execute in parallel. Control
is returned to the client session immediately after a sign-on when NOSIGNONWAIT
is specified.
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.
