When you invoke SAS as a server
that responds to multiple clients, you can use the
DBSRVTP= system option to improve the performance of the clients.
This option tells the SAS server whether to put a hold (block) on
the originating client while making performance-critical calls to
the database. By holding or blocking the originating client, the
SAS/ACCESS
server remains available for other clients; they need not wait for
the originating client to complete its call to the database.
