Chapter 3. Workplace Managed Client 2.6 on Linux installation and configuration 91
This section describes the installation procedure on a typical Linux desktop. Is
there such a thing? Here is how we have qualified a typical Linux workstation for
the purposes of this book:
򐂰 It is essentially a single-user system because only one user logs in on a
day-to-day basis.
򐂰 The OS is installed on the local disk.
Note the similarities with a typical Windows workstation.
Note also that we are not considering how the workstation is used, but how it is
deployed (1.2.2, “Linux desktop classifications” on page 6).
Because this is the most common type of Linux workstation deployment and the
one most tested by the Managed Client, this is the installation procedure we
describe in this guide.
3.2.2 Prerequisites
This section provides the prerequisites.
Supported platform
The supported platform for Workplace Managed Client 2.6 is Red Hat Enterprise
Linux Workstation 3, Update 4.
Configuring the browser for Java
For the client download link to initiate the Managed Client installer automatically,
Java must be configured properly in the user’s browser. Although it is not
required to install the Managed Client through the download link, we strongly
advise that you install it this way.
In this section, we outline the steps required to configure Java on both Mozilla
and Firefox browsers under Red Hat Enterprise Linux Workstation 3, Update 4.
Tip: Appendix A, “Installing IBM Workplace Managed Client on other Linux
distributions” on page 195 describes how you can install the client some
unsupported, albeit common, Linux distributions.
Tip: Owing to the large number of possible combinations of both distributions,
browsers, and JREs, it is not possible to publish a definitive guide even for the
supported platform. However, the instructions in this section should be generic
enough for use with any distribution.

Perform the following steps:
1. Obtain either the IBM or Sun™ Java™ runtime environment (JRE). Download
the Sun JRE from their Web site. In either case, we recommend a 1.4 or later
2. Install the JRE into a suitable location on the client workstation. In this guide,
we choose /opt/. For example, if we choose IBM JRE Version 1.4.2, the JRE
is in /opt/IBMJava2-142/. Make a note of the directory name; in this book, we
substitute $JAVA_HOME with that value.
3. The final step is to create in our browser’s plug-ins directory a symbolic link to
the browser plug-in shared library provided by the JRE. We must locate some
files and directories:
a. Where is the browser’s plug-in directory? On a standard Red Hat
Enterprise Workstation 3 Update 4 machine, the Mozilla plug-in directory
is /usr/lib/mozilla-1.4.3/. Firefox does not come with this distribution, but if
you have downloaded it from and
extracted it to /opt, the plug-ins directory is simply /opt/firefox/plugins. In
this book, we substitute $PLUGIN_DIR with this value.
b. Where is the JRE browser plug-in shared library? It is called something
similar to For an IBM JRE, it is probably in the jre/bin
directory under the directory into which you installed the JRE. With a Sun
JRE, it is probably in jre/plugin/i386/ns610 or jre/plugin/i386/ns610-gcc32.
In this book, we substitute $PLUGIN_SO with this value.
c. Now, to create the link, enter:
ln -s $PLUGIN_SO
4. To verify that the plug-in is successfully installed, enter about:plugin into the
address bar of your browser (Mozilla or Firefox). Verify that Java is listed.
Important: The IBM JRE supplied with Red Hat Enterprise Linux
Workstation 3, Update 4 is Version 1.3.1 and incompatible with Mozilla and
Firefox. You must use a later edition of the JRE.
Tip: If there are multiple directories with names of the form
/usr/lib/mozilla-X.X.X, try the directory with the highest number.
Tip: For a list of all possible plug-in shared libraries, use this command:
find $JAVA_HOME -iname *oji*.so
