### Uninstall options

Similar to install WebSphere Portal has provides you with three options for which method you want to use for unistalling portal.

• Graphical: The Graphical is default option that you get if you execute ./uninstall.sh or uninstall.bat command in the portal_server/uninstall director. It will open a Wizard and ask you couple of questions about what is user name and password of portal administrator and do you also want to uninstall websphere portal.

• Console: If your using a system where Graphical Uninstall/install is not supported then your second option is to use Console by executing ./uninstall.sh -console in this case portal will ask you same question as that of graphical unistall but on command console.

• Silent Install If your Operating system does not support Graphical UI then you can use the silent option. In this case you copy the uninstallresponse.txt file from the IL-Setup or W-Setup directory set appropriate properties and execute ./uninstall.sh -options <path_to_setup>/IL-Setup/unistallresponse.txt

The CentOS vmware that i use for experiments does not support Graphical UI so i had to uninstall using the silent option. This is how my uninstallresponse.txt looks like.

Once you start the uninstall process it will display name of the log file where uninstall process is writing long in my case it is /tmp/wpuninstalllog.txt file. You can look inside this file in case of problems.

Both during the install and uninstall process the installer creates portalinstall.lock file to make sure that there is only one instance of installer/uninstaller program is running at a time. If your install or uninstall process is throwing other instance of installer already in progress check if this file is there in either /tmp folder in case of Linux or in C:\Documents and Settings\Administrator\Local Settings\Temp\portalinstall.lockfile folder in case of Windows. Delete this file manually and then start the install/uninstall program.
