Appendix A. SUSE Linux sample installation 359

Java Runtime Environment

By default, SUSE Linux installs the SUN Java Runtime Environment (JRE) V1.3.

We found that such applications as DB2 Universal Database (UDB), Tivoli

Access Manager, and the IBM GSKit were dependent on the IBM Java Runtime

V1.3.1. We found that the SUN JRE caused problems to leave it installed. For

this reason, we uninstalled the SUN JRE.

For more information, see “Configuring IBM Java Runtime Environment V1.3.1”

on page 366.

Perl required by IBM GSKit installer

Perl is required by the IBM GSKit installer. We need an updated version of the

IBM GSKit to properly create the key store and certificates. The version of the

IBM GSKit supplied with the IBM Tivoli Directory Server V5.2 does not work

properly.

Refer to “Installing and updating Perl” on page 364 for details.

VMWare Workstation tools considerations

If you are using VMWare to build a test environment, as is the case for the ITSO

working example test environment, after the SUSE Linux installation, you must

install the VMWare tools to optimize performance.

Refer to “Installing VMWare tools” on page 362 for more information.

VMWare Workstation and network configuration

If you are using VMWare to build a test environment, as is the case for the ITSO

working example test environment, after the SUSE Linux installation, we

recommend that you configure the TCP/IP network using static addresses and

use the /etc/hosts file to resolve names. For example, we included the following

in /etc/hosts file for each of our nodes:

192.168.2.100 ldaplx1.itso.ral.ibm.com ldaplx1

192.168.2.110 wpslx1.itso.ral.ibm.com wpslx1

192.168.2.120 tamlx1.itso.ral.ibm.com tamlx1

192.168.2.130 wslx1.itso.ral.ibm.com wslx1

Installing SUSE Linux Enterprise Server V8

To install the SUS Linux Enterprise Server V8:

1. Insert UnitedLinux CD1, and boot it from the drive to start the installer.

2. When you see the SUSE Linux Enterprise Server startup window, select

Installation.

3. In the UnitedLinux license agreement window, review the agreement, and

click Accept if you agree to the conditions of the agreement.

4. In the Welcome to YaST window, select the desired language (for example,

English - US), and then click Accept.

5. In the Installation Settings window, make the appropriate selections. Then,

click Accept. For this example, we made the following selections:

– Mode: new installation (default)

– Keyboard layout: English - US (default)

– Mouse: IntelliWheel mouse - Aux-port (default)

– Partitioning:

• Create swap partition 1.0 GB on /dev/sda1

• Create root partition 9.0 GB (/dev/sda2 with reiser)

– Software:

There are many possible software options. We selected or deselected the

options shown in Table A-1 for our configuration by clicking Software and

then clicking Detailed selection, making the necessary changes, and

then clicking Accept.

Table A-1 Software options

Note: In our example, we use VMWare Workstation V4.5.2 with a

10 GB virtual hard disk 1024 MB of virtual memory. For a test

environment, we choose to create one root partition for all software to

be installed. In a production environment, you may choose to create

separate partitions.
