Best Practices for Middle-Tier Configuration

This chapter provides sample middle-tier topologies and guidelines for achieving better efficiency and performance with the middle-tier components in the SAS Intelligence Platform. The middle tier provides an environment for running the following SAS Web clients:

Configuration instructions vary depending on the Web application server installed at your site. For configuration instructions that pertain to the topics discussed in this chapter, see the following third-party vendor Web sites:

For deployments that use WebSphere Application Server, if you want to configure the middle-tier environment manually, then configure a separate cell for the SAS Web applications. The SAS Web applications make use of resources that are configured at the cell level. Configuring a separate cell avoids interference between the SAS Web applications and other Web applications.

For deployments that use WebLogic Server, if you want to configure the middle-tier environment manually, then configure a separate domain for the SAS Web applications. The SAS Web applications make use of resources that are configured at the domain level. Configuring a separate domain avoids interference between the SAS Web applications and other Web applications.

For deployments that use JBoss, if you want to configure the middle-tier environment manually, then configure separate Web application server instances for the SAS Web applications. Do not deploy the SAS Web applications to Web application server instances that are used for other Web applications. Likewise, do not deploy other Web applications to the Web application server instances that are used for the SAS Web applications.
