You must ensure your Linux system is prepared to install IBM WebSphere ESB.
The installation uses an InstallShield for Multiplatforms (ISMP) wizard. You can also install the product silently. Silent mode is invoked at a command line with a parameter that identifies an options response file, which you edit before installing.
Use the following procedure to prepare the operating system for installation of WebSphere ESB.
You cannot install the product correctly as a non-root user. If you create copies of the product CDs, do so as root. Copies made by non-root users do not preserve the correct file attributes and do not work.

Download and install the Mozilla browser from http://www.mozilla.org.
Export the location of the supported browser using a command that identifies the actual location of the browser.
EXPORT BROWSER=/usr/bin/mozilla
For the space required to install WebSphere ESB and related products, see Required disk space on Linux platforms.
Although the Installation Wizard checks for prerequisite operating system patches, review the prerequisites in the List of supported hardware and software for WebSphere ESB if you have not already done so. To access this information, see WebSphere ESB detailed system requirements at http://www.ibm.com/software/integration/wsesb/sysreqs/.
Refer to the documentation for non-IBM prerequisite and corequisite products to learn how to migrate to their supported versions.
A known limitation exists in the prerequisites checker program when examining prerequisite packages on Linux systems.
The following package is required for Red Hat Enterprise Linux V3.0 for pSeries platforms: rpm-build-4.2.1-4.2.
You can install a later release of any of these packages.
Upgrade the Red Hat Enterprise Linux V3.0 service level by downloading and installing the service updates from Red Hat.
If you do not upgrade the service level, certain national language issues in the released version of GLIBC included in Red Hat Enterprise Linux V3.0 might cause Java Virtual Machine (JVM) failures due to segmentation faults. These failures can occur during installation when the locale is set to anything other than an English locale.
Do not install, log off, and log back on when you are installing from the operator console attached to the machine. This action can produce segmentation faults that cause the installation to fail.
It is your responsibility to install this service pack. The prereqChecker function of the installer cannot detect service pack versions definitively on United Linux. Kernel unames and versions between 8.0 and 8.0.3 are identical. No signature RPM denotes a service pack install.
To use the IBM Developer Kit, remove the java2-jre-1.3.1-524 and java2-1.3.1-524 RPMs from the machine before installing WebSphere Process Server.
On the Linux for Power platform that SuSE Linux Enterprise Server 8.0 provides, a missing package causes a font problem. The ttf-hanyi package is not installed during the normal product installation of the SuSE 8.0 operating system. The missing package causes the Installation Wizard for WebSphere ESB to display garbled characters in the Simplified Chinese locale and in the Traditional Chinese locale.
To fix this problem, copy the ttf-hanyi-2021016-0.noarch.rpm package on the SuSE 8.0 for i386 CD to the Power PC system, install the package, and reboot the machine.
If you install the product using a cp command that is part of a freeware package, rather than with the system cp command, the installation might appear to complete successfully, but the Java 2 SDK that the product installs might have missing files in the install_root/java directory (where install_root represents the installation directory of WebSphere ESB).
Missing files can destroy required symbolic links. You must remove the freeware cp command from the PATH in order to install the WebSphere ESB product successfully.
If you have emacs or other freeware installed on your operating system, perform the following steps to identify which cp command is being used by the system, and to deactivate the freeware cp command if it is being used:
If you created your own product CDs from ISO images or by copying the actual CDs, perform the following steps to verify that the Java 2 SDK is working correctly.
cd /mnt/JDK/repository/prereq.jdk/java/bin
./java -versionThe command completes successfully with no errors when the Java 2 SDK is intact.
This procedure prepares the operating system for installation of WebSphere ESB.
