The SAS desktop client
applications and majority of Java applications are supported on Microsoft
Windows systems only. The exception is SAS Management Console, which
also runs on several UNIX platforms. All of the Java applications
require the Java Runtime Environment (JRE), which includes a Java
Virtual Machine (JVM) that executes the application and a set of standard
Java class libraries. The SAS Deployment Wizard will install the default
version of the 32-bit JRE with which SAS has been tested. If a different
supported version of the JRE is required, it can be obtained from
the appropriate vendor's Web site. Links to the appropriate JRE vendor's
Web site can be found on the SAS 9.3 third-party support site located
at
http://support.sas.com/resources/thirdpartysupport/v93.
During a first-time
SAS 9.3 deployment, the SAS Deployment Wizard prompts you for the
version of the JRE that you want to use with the SAS Java applications.
Your options are to have the deployment wizard install a JRE that
SAS has certified to run with SAS 9.3, or to point to a JRE that you
have already installed. (In most situations where you are updating
or adding a product to SAS 9.3, the deployment wizard does not prompt
you for a JRE. However, you can override this behavior. For more information,
see
Specify a Different JRE.)
On
z/OS only, your options
are to point to a JRE that you have already installed, or install
your software without a JRE.
In most cases, before
you can install and configure a SAS 9.3 middle tier, you must have
installed a Web application server and a 64-bit JDK that is supported
by SAS. (If you are using WebSphere Application Server, then the JDK
is supplied when you install WebSphere Application Server.) SAS identifies
the supported software versions at:
http://support.sas.com/resources/thirdpartysupport/v93.
When you run the deployment
wizard on the middle-tier machine, it prompts you for paths to these
third-party software products, checks to make sure that the software
versions are supported by SAS, and does not allow you to proceed with
the software installation unless the software is installed. However,
some sites separate SAS administration from Web application server
administration, and it might not be possible to run the deployment
wizard on the middle-tier machine.
For the sites that do
not permit running the deployment wizard on the middle-tier machine,
the wizard enables the SAS administrator to create a middle-tier configuration
on a machine that does
not contain
a Web application server. After the configuration is complete, the
SAS administrator compresses the Web tier configuration and hands
it off to his Web administrator counterpart to deploy on the target
Web application server machine. For more information, see
Building a Web Application Server Configuration for Deployment on Another Machine.
The Web application
server administrator can then choose to use configuration scripting
tools provided by SAS to configure the middle-tier environment on
the target machine, or the administrator can configure the middle-tier
manually. For more information about the configuration scripting tools,
see
SAS Configuration Scripting Tools in SAS Intelligence Platform: Middle-Tier Administration Guide.
Use the manufacturer's
distribution package to install the JDK. Make sure that you have a
properly defined Java environment. (On Windows, a reboot of the machine
might be required.) Open a DOS command prompt on Windows, or a console
on UNIX, and at the operating system prompt, enter the following command
to validate the Java environment and return the version information
(including bitness) for the installed package:
java -version.
