Preparing for Installation |
The installation process is easy and straightforward; however, it is essential that you verify all requirements before you install Sun Ray Server Software 4.1. This chapter describes what you need to do.
Topics in this chapter include:
Before you install Sun Ray Server Software, you should:
Make sure that you are running the desired supported operating system on your system.
Make sure that the system(s) on which you plan to install the software fulfills the necessary hardware and software requirements.
The standard installation of Sun Ray Server Software requires at least 95 MB of disk space. TABLE 2-1 lists the disk space requirements for specific directories.
Note - The suggested server configuration includes approximately 50-100 MB of swap space per user. |
SRSS 4.1 requires JRE version 1.5 or later. The latest Java release is available at:
http://java.sun.com/j2se
JRE version 1.5 is also bundled on the SRSS 4.1 CD, in the Supplemental directory.
By default, J2SE 5.0 on server-class machines -- those with at least two CPUs and two GB of physical memory -- uses a server JVM, rather than a client JVM for Java applications. The server JVM’s default options also are tuned for server-type Java applications. These combined defaults produce a large memory footprint and extend the necessary startup time, both of which are undesirable for Java applications in a multiuser environment.
Use the -client option to the java command to specify the client JVM for Java user applications on the Sun Ray server. For further details, see:
http://java.sun.com/j2se/1.5.0/docs/guide/vm
Note - Since the 64-bit JVM is a server VM only, the 32-bit client JVM is preferable, even on 64-bit systems. |
Sun Ray Server Software 4.1 runs on:
All packages are required and must be installed. In addition to the default RPMs selected, add the following items:

![]() |
Caution - The Red Hat installation script asks whether to start a graphical console. Be sure to answer “Yes”, otherwise Sun Ray startup scripts and X initialization scripts may fail to run. |
The Sun Ray Administration Tool (Admin GUI) requires that a Web server be installed and running on each Sun Ray Server. Since the previously used CGI-based rendering logic has been completely removed, the new Admin GUI must be hosted in a Web container that supports the Servlet 2.4 and JavaServer Pages 2.0 specification. The Apache Tomcat 5.5 Web container implements these standards and runs on any operating system that has a Java Runtime Environment (JRE).
The utconfig script prompts for the location of an Apache Tomcat HTTP Server and asks whether it should be configured automatically.
An Apache Tomcat 5.5 archive is included in the Sun Ray Server Software 4.1 image under Supplemental/Apache_Tomcat. The most recent version of Tomcat 5.5 can be downloaded from http://tomcat.apache.org.
The Sun Ray configuration script uses port 1660 for the Sun Ray Administration Tool (Admin GUI) by default. If this port is unavailable, you can configure a new port while running the utconfig script.
If Tomcat 5.5 is already installed on your system, you can omit the steps below and specify the path, if necessary, during configuration (see Configure Sun Ray Server Software).
1. As superuser, open a shell window on the Sun Ray server.
2. Change to the Apache_Tomcat directory, for instance:
3. Extract the Tomcat archive into a suitable directory, such as /opt:
4. For convenience, you can create a symbolic link to the installation to make future Tomcat updates easier:
To view the Sun Ray Administration Tool (Admin GUI), you must have a Web browser, such as Mozilla or Netscape Communicator, installed on the system that will display it.
The latest version of the Mozilla browser is available at:
http://www.mozilla.org/download.html
The latest version of the Netscape Communicator Web browser is available at:
http://www.netscape.com/download
If you already have an LDAP (Lightweight Data Access Protocol) server configured on the Sun Ray server, it can coexist with Sun Ray Data Store; however, it must not use port 7012, which is reserved for use by the Sun Ray Data Store.
