In SAS 9.4, a change has been made in how the Java Runtime Environment (JRE) is installed. The most noticeable change is that the SAS^® Deployment Wizard no longer prompts for the JRE. Instead, the SAS Private JRE (PRIVATEJRE) is installed in the SASHOME directory without prompting you. This means that, by default, all products use the SAS Private JRE, and you are not required to pre-install a JRE.

There are two places that you see the entry for the SAS Private JRE for SAS 9.4: the sassw.config file and the sasv9.cfg file.

The sassw.config File

The sassw.config file is located in the !SASHome directory. The default location is C:\Program Files\SASHome.

Note: If you already have SAS^® 9.3 installed on your PC, the new SASHome location for SAS 9.4 is SASHome2.

There are now two entries for Java in this file: the JREHOME and PRIVATEJRE entries.

Here is an example:

The sasv9.cfg File

The sasv9.cfg file is located in the !SASRoot directory. The default location is C:\Program Files\SASHome\SASFoundation\9.4\nls\en. An example of the file is shown below.

Note: If you already have SAS^® 9.3 installed on your PC, the new SASHome location for SAS 9.4 is SASHome2.

What You See during the Installation Process for the SAS Private JRE

During the installation process, you are not prompted for the JRE. As shown below, the Deployment Summary window and the Deployment in Progress window indicate that the JRE is being installed.

Additional Change

You are no longer prompted for the Java Development Kit (JDK). SAS is using the SAS 9.4 web application server, which requires only the PRIVATEJRE.
