Determine the IP Address of the Linux Server, check the field beside "inet addr:" beside eth0 running the below command:

  •   ifconfig
  •   Note, if you have multiple NICs, you will see multiple eth like eth0, eth1. Please consult your system administrator to determine the right IP in a multiple IP environment

Find the hostname running the below command:

  •   hostname

Backup and edit the /etc/hosts file with the IP Address and the hostname on the Linux Box as below:

  • 127.0.0.1 localhost localhost.localdomain <IP Address> <hostname>

    For example, if the IP Address is 10.0.0.0 and the host name is testbox1.testbox.com, the /etc/hosts file should look like:

    127.0.0.1 localhost localhost.localdomain 10.0.0.0 testbox1

(please refer Additional Information for details)

Install the 32-bit and 64-bit RPMs and its dependencies (please refer Additional Information for details)

Create a normal non root user to be used as the "Installation User" when prompted for a username later during the installation (refer Additional Information for further information on creating a normal user)

Upload the Spectrum image to the RHEL Box (if the ftp protocol is used - remember to upload the image in binary mode)

Untar and Unzip the RHEL image to extract the image running the below commands:

  •   gunzip <image name>
  •   tar -xvf <image name>

Stop all non-CA Spectrum running applications

Stop any CA Spectrum running applications

Change Directory (cd) to the extracted image directory, run the below command to start the installation:
