Workspace pooling creates a set of server connections
that are reused. This reuse avoids the wait times that an application
incurs when it creates a new server connection for each user. You
can also use pooling to distribute server connections across machines.
Pooling is most useful
for applications that require frequent, but brief, connections to
a SAS Workspace Server. Two types of pooling are supported:
a configuration in
which the SAS object spawner maintains a collection of re-usable workspace
server processes that are available for clients. The usage of servers
in the pool is governed by authorization rules that are set on the
servers in the SAS metadata. Load balancing is automatically configured
for these servers.
By default, applications
such as SAS Information Map Studio, the SAS Information Delivery Portal,
and SAS Web Report Studio use SAS Pooled Workspace Servers to query
relational data. SAS Pooled Workspace Servers are configured to use
server-side pooling and load balancing.
a configuration in
which the client application maintains a collection of reusable workspace
server processes. In releases prior to 9.2, client-side pooling was
the only method of configuring pooling for workspace servers.
