Preparing for reinstallation after a failed uninstallation on an AIX system

This procedure cleans an AIX system if uninstallation of WebSphere ESB fails. After running the uninstallation program, these manual steps remove registry entries that can prevent you from reinstalling the product into the original directory. If you are not planning to reinstall, do not perform this task.

Before you begin

Before performing this procedure, ensure you have uninstalled WebSphere ESB using the Uninstallation wizard or silently, and that the procedure was not completely successful. If the procedure was successful, you do not need to perform this task.

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

Default directories are shown in Table 1:

Table 1. Planning table for identifying actual location of product installation
Identifier Directory location
install_root
Default location /usr/IBM/WebSphere/ESB or /usr/IBM/WebSphere/AppServer
Actual location  
profile_root
Default location /usr/IBM/WebSphere/ESB/profiles/profile_name or /usr/IBM/WebSphere/AppServer/profiles/profile_name
Actual location  
The Installation wizard and the Profile wizard let you specify your own locations for installation root directories. Examine the following files to determine the actual locations:
  • The ~/.WBIRegistry file identifies the installation root for all installed WebSphere ESB products; the ~/.WASRegistry file, for all WebSphere Application Server products. These files are located in the home directory of the user ID from which the product was installed.
  • The install_root/logs/wasprofile/wasprofile_create_profile_name.log file for each created profile identifies the installation location in the stanza with the <method>invokeWSProfile</method> tag.
Uninstalling the product leaves the profile_root directory, including the profile_root/logs directory with the pcatLog<timestamp>.txt file, where profile_root represents the installation location of the profile. It leaves the install_root/logs directory as well.

Why and when to perform this task

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 WebSphere ESB. A clean system lets you reinstall the product into the original directory without coexistence.

Important: Throughout this procedure, steps address removing artifacts left after uninstallation of both WebSphere ESB and WebSphere Application ServerNetwork Deployment. The WebSphere Application Server product addressed is assumed to be the one underlying the installation of WebSphere ESB.

Perform the following procedure to produce a clean system.

Steps for this task

  1. Log on as root.
  2. Use the kill command to kill all Java processes that are running.
    If you are running Java processes that are not related to WebSphere ESB or WebSphere Application Server products and it is not possible to stop them, stop all WebSphere ESB and WebSphere Application Server product-related processes. Use the following command to determine all processes that are running:
    ps -ef | grep java
    Stop all WebSphere ESB and WebSphere Application Server product-related processes with the kill -9 java_pid_1 java_pid_2...java_pid_n command.
  3. List WebSphere ESB and WebSphere Application Server components that are installed.
    Type the following command to search for related packages:
    lslpp -l | grep -i WS 
    To narrow your query to search for WebSphere ESB packages only, type the following command:
    lslpp -l | grep -i WSEAA60 

    WebSphere ESB package names have a prefix of WSE and a suffix of 60. WebSphere Application Server Network Deployment package names have a prefix of WSB or WSP and a suffix of 60. Do not remove packages for WebSphere ESB and WebSphere Application Server products that you did not uninstall.

  4. Use the geninstall command to remove registry information for each component that is displayed in the list (for products that you uninstalled).
    For example, issue the following command to show packages with a prefix of WSE:
    lslpp -l | grep -i WSE

    The system displays the list of matching packages.

    Issue the following command to remove a registry entry (for example, WSEAA60WBICoreComponent-6.0-0):
    geninstall -u WSEAA60WBICoreComponent-6.0-0
  5. Remove any profile directories that are not located in the installation root (install_root) directory.

    To determine the locations of profile directories, first use the manageprofile -listProfiles command to display profile names. Then, to determine where profile directories are located, use the manageprofile -getPath -profileName profile_name command, where profile_name is the name of the profile corresponding to a given directory.

  6. Remove the installation root directory. Type rm -rf install_root to remove WebSphere ESB directories. Ensure you specify the correct install_root for the product you uninstalled. For example, if you uninstalled WebSphere ESB from the default directory /usr/IBM/WebSphere/ESB, issue the following command:
    rm -rf /usr/IBM/WebSphere/ESB
  7. Edit the vpd.properties file to remove the entries for WebSphere ESB and WebSphere Application Server Network Deployment.

    The file is located in the installation directory of the operating system, such as the root directory. Remove all entries for the installation of WebSphere ESB that you have uninstalled. Each WebSphere ESB entry starts with the characters WSE, followed by numbers representing the release number, and on the same line will have the install_root path corresponding to the installation you have uninstalled. (Each entry is on a single line if the file is displayed in a text editor with word wrap turned off.)

    Each WebSphere Application Server Network Deployment entry in the vpd.properties file has a similar format. For information about these entries to help you determine which to delete, and for more information about the vpd.properties file, refer to the WebSphere Application Server Network Deployment, version 6.0 information center.

    Do not delete or rename the vpd.properties file because the InstallShield for MultiPlatforms (ISMP) program uses it for other products that it installs. If the WebSphere ESB or WebSphere Application Server product that you are uninstalling is the only product with entries in the vpd.properties file, you can delete this file.

  8. Edit the .WBIRegistry and .WASRegistry files.

    These files are located in the home directory of the user ID from which the product was installed.

    The .WBIRegistry file contains a one-line entry for each WebSphere ESB product installation; the .WASRegistry file, for each WebSphere Application Server product installation.

    You can delete these files if there is just one line in each that identifies the product that you removed. Otherwise, use a flat-file editor to remove the line that identifies the installation root directory of the product that you removed. Leave the other lines intact. Do not delete the .WBIRegistry and .WASRegistry files unless you removed all of the installations listed in the files.

  9. Run the odmclean.sh and aixclean.sh scripts.

    Do not run the aixclean.sh script if the WebSphere MQ product is installed.

    1. Obtain the scripts from the technote document titled, Manual uninstall On AIX requires odmclean.sh and aixclean.sh on the WebSphere Application Server Support site.
    2. Edit the odmclean.sh script and replace every instance of the string /usr/WebSphere/AppServer with the actual installation root directory.
    3. Run the aixclean.sh script from the command line:
      ./aixclean.sh
    4. Run the odmclean.sh script from the command line:
      ./odmclean.sh

Result

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.

What to do next

After you have cleaned your system, go to Installing WebSphere ESB to choose an installation procedure.
