vi What’s New in SAS Web Applications Clustering SAS Content Server Modifications When SAS Content Server is clustered, one instance must be identified in the -Dsas.scs.host and -Dsas.scs.port JVM options. This modification is made to the JVM options for all Web application server instances. They are all modified to use a single host name and port number. SAS BI Dashboard Modifications When SAS BI Dashboard is clustered on Oracle WebLogic Server, the weblogic.xml file for the sas.bidashboard.war file must be modified. The file is modified to include a cookie name that is used for session affinity.

Performance is improved due to additional server instances to handle requests and distribution of memory needs to additional processes. Performance can also be improved by deploying servers on to additional hardware. Clustering can also provide high availability. If server instances are clustered on a single machine, then there is protection against software failure. If multiple machines are used for clustering servers, then the additional machines in the cluster provide protection from software failure and protection from hardware failure. This document provides application-specific considerations for clustering and Web application server-specific details for clustering the SAS Web applications that are deployed with SAS Enterprise Business Intelligence Server. Here are the high-level steps to follow: 1 Plan for Deployment: Using functional and non-functional requirements as well as a sizing and capacity plan, determine how many servers you need and the server capacity that you need. 2 Choose Deployment Plan: Based on the input from the previous step, choose a deployment plan that uses single or multiple servers. 3 Install SAS Software with the SAS Deployment Wizard: Use the wizard to install SAS software either interactively or non-interactively. The interactive method provides a series of prompts to enable you to modify parameters based on your environment. Alternatively, you can configure a response file with parameters for your environment and run the wizard in noninteractive mode. On the first machine in the middle tier, use the SAS Deployment Wizard to install and configure software. You can choose to have the wizard automatically configure the Web application server, or configure the Web application server yourself. If you choose to configure the Web application server yourself, follow the steps in the Instructions.html file that is generated by the wizard. On the additional 1
