WPS: Pre-install Tasks for Linux

Follow the next steps carefully for install IBM Websphere Portal Server 6.1 for Linux

Hardware

Have at least 2 GB of RAM for installation

In my installation, i had problems when my Virtual Machine (VM) has only 1 GB of memory, with more memory the install happens without problems. In the installation process the Wizard start and stop WAS/WPS many times, so enough memory is a pre-req.

Installing requireds RPM packages

Install the following RPM packages in you Linux OS:

 - compat-libstdc++-33
 - compat-libstdc++-296
 - libXp

if you are using yum, make as follow:

> yum -y install compat-libstdc++-33 compat-libstdc++-296 libXp

Setting the hostname as FQDN

Check that the hostname is full hostname (Full Qualified Domain Name).

Example: wps1.mycompany.com

Another Example:

> cat /etc/hosts
127.0.0.1              localhost.localdomain            localhost
192.168.1.15           wps1.mycompany.com               wps1

(Optional) Updating the /etc/issue file - Only for CentOS

InstallShield checks for Operation System installed to know for it's compatibility or not. We can avoid/mask this check change the /etc/issue file. So the same thinks this OS is a trully Red Hat Enterprise

The original is the following one:

CentOS release 5 (Final)
Kernel \r on an \m

Update to:

Red Hat Enterprise Linux ES release 4 (Nahant Update 1)
Kernel \r on an \m

Logoff and Logon again.
