Co-existing Installations of WPS 6.1 on Linux

It had been a quite loaded last week for me. Currently working for one of our prestigious clients John Deere, I come across a requirement which is less common in today's portal infrastructure scenario across the organizations. Might be due to cost saving on hardware as well as software resources client wants to have two portal server 6.1.0.1 instances on single linux box with existing WAS. Looked nearly impossible on first attempt, we got it working after concentrated research on co-existing intallations.

Here I am making it quite easy for you by compiling them into following steps.

• Install the first portal instance on your linux box. Here is a link.
• Varify your installaton by hitting the portal URL as well as application console URL.
• Before installing second Portal Server instance make sure that all the applications on that linux box have been started so as to avoid any port conflicts.
• This second portal installation will be using an existing WebSphere directory with an existing instance of WebSphere Application Server.
• run the following command on the terminal.

./install.sh -console -W globalInstall.active=false -W was.undetectedWas="/opt/ibm/WebSphere" -W globalInstall.location=/opt/ibm/WCM -W wasLocationExistsSequence.active=false -W detectProfileAction.profileName="wcm_profile" -W detectProfileAction.profilePath=/opt/ibm/WebSphere/wcm_profile -W invalidProfileExit.active=false

Note: The directory that is specified for globalInstall.location cannot already contain an installation of Portal. If Portal exists in the desired directory, the EJPIC0054E exception occurs and a new unique directory (WCM in this case) must be used. However, even in this case, the existing installation of WebSphere Application Server can still be used with Portal. In addition, the directory specified by detectProfileAction.profilePath cannot exist prior to installation.

• Enter the appropriate values when prompted and check for the successfull installation.

Here is a technote from IBM which will help you in troubleshooting any problem you face during this procedure.
