The SAS 9.4 middle-tier
environment provides an execution environment for SAS web applications
that are used to perform business analytics. The SAS 9.4 release has
added functionality that enables you to automatically configure a
clustered environment for the SAS web applications. As a result of
this added functionality, optimizing the middle tier and SAS web applications
for scalability and performance is greatly simplified.
The purpose of this document is to walk through the SAS 9.4
tuning for performance and scalability. This document includes the tuning methodology and
tuning parameters for SAS web applications, SAS Web Application Server, Java Virtual
Machine (JVM), and the supported operating systems.
