Manually uninstalling on a Solaris system

 

This procedure uninstalls the WAS product from a Solaris system. After running the uninstaller program, manual steps remove log files and registry entries that can prevent you from reinstalling the product into the original directory. If you are not planning to reinstall, do not uninstall manually.

The uninstaller program removes all profiles by default, including all of the configuration data and applications in each profile. Before you start the uninstall procedure, back up the config folder, the installableApps folder, and the installedApps folder of each profile, if necessary, or use the -OPT removeProfilesOnUninstall="false" parameter on the uninstall command. See Use command line tools for a description of managing configuration files. Back up all applications that are not stored in another location.

Determine the installation root directory for the product so that you remove the correct product and produce a clean system.

 

Overview

Reinstalling the product into a new directory when files remain from a previous installation can create a coexistence scenario. However, you can delete all files and registry entries to completely remove a WAS product. A clean system lets you reinstall the product into the original directory without coexistence.

Default directories are shown in the following planning table:

Identifier Directory Actual location
app_server_root /opt/IBM/WAS/AppServer  
profile_root /opt/IBM/WAS/AppServer/profiles  
plugins_root /opt/IBM/WAS/Plugins  

The installation wizard and the Profile Management tool provide an override for your own locations for root directories.

Use the installRegistryUtils command to examine the installation locations for all installed WebSphere Application Server products.

Perform the following procedure to produce a clean system.

 

Procedure

  1. Log on as the same user ID who installed the product.

  2. Run the uninstaller program for the Web server plug-ins for WAS.

    If a Web server is configured to run with the appserver, uninstall the plug-ins to remove the configuration from the Web server. See Uninstall the Web server plug-ins for WAS.

  3. Use the kill command to kill all Java processes running. If running Java processes are not related to WAS products and it is not possible to stop them, stop all WAS product-related processes. Use the following command to determine all processes running: 

    ps -ef | grep java
    Stop all WAS-related processes with thekill command. 

    kill -9 java_pid_1 java_pid_2...java_pid_n

  4. Issue the uninstall command.

    If you have already run the uninstaller program or if you cannot run the uninstaller program, skip this step. 

    app_server_root/uninstall/uninstall

    See the description of the uninstall command for more information.

    The Uninstaller wizard begins and displays the Welcome panel.

  5. Search for related packages. Type the following command to search for packages for WAS products: 

    pkginfo | grep WS

    If no packages appear when using these commands, skip the next step. The resulting list of packages has the following format: 

    application WSBAA61        WAS

  6. Change directories to the directory where package information is registered. 

    cd /var/sadm/pkg

  7. Issue the following command to remove any WebSphere Application Server-related packages. 

    pkgrm packagename1 packagename2 packagename3 ...

    Do not remove packages for WebSphere Application Server products that you are not uninstalling. V6.1 package names have a prefix of WSB or WSP and a suffix of 61. WSC package names do not have a suffix of 61. Issue the following commands from the /var/sadm/pkg directory to search for and remove any WAS product-related packages that are registered in the /var/sadm/pkg directory:

    1. Change directories to the correct directory: cd /var/sadm/pkg

    2. ls |grep WSB|xargs -i pkgrm -n {} for WebSphere Application Server products

    3. ls |grep WSC|xargs -i pkgrm -n {} for Application Client

    4. ls |grep WSP|xargs -i pkgrm -n {} for Web server plug-ins for WAS

    Package names for Web server plug-ins for WebSphere Application Server are: 

    WSPAA61 WSPAA61AC  WSPAA61BC  WSPAA61CC  WSPAA61DC  WSPAA61FC  WSPAA61FB WSPAA61GC WSPAA61HC

    If there is a problem removing the packages, remove the related package directories in the /var/sadm/pkg directory, including the preremove files. For example, remove the following file before issuing the pkgrm -n WSBAA61 command: 

    /var/sadm/pkg/WSBAA61/install/preremove

  8. Type rm -rf app_server_root to remove WAS directories in the app_server_root directory. Do not remove installation root directories for products that you intend to keep. Remove all of the profile directories as well.

  9. Use the installRegistryUtils command to examine the installation locations for all installed WebSphere Application Server products and remove the desired products from the install registry.

 

Results

This procedure results in having a clean system. You can reinstall into the same directories now. A clean system has no trace of a previously deleted installation.
