Workspace Pooling for SAS Workspace Servers

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. SAS 9.2 supports the following two types of pooling:

server-side pooling

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.

client-side pooling

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.

For more information about pooling, see the SAS Intelligence Platform: Application Server Administration Guide.
