Manually uninstalling on an HP-UX system
This procedure uninstalls a WAS product from an HP-UX 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.
Before you begin
The uninstaller program removes all profiles, 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. See Using 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.
Reinstalling the product into a new directory when files remain from a previous installation can create a coexistence scenario. However, one 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 install_root /opt/IBM/WebSphere/AppServer profiles_install_root /opt/IBM/WebSphere/AppServer/profiles plug-ins_install_root /opt/IBM/WebSphere/Plugins The Installation wizard and the Profile creation wizard let you specify your own locations for installation root directories. Examine the following files to determine the actual locations:
- The ~/.WASRegistry file identifies the installation root for all installed WAS products.
- The install_root/logs/wasprofile/wasprofile_create_profile.log file for each created profile identifies the installation location in the stanza with the <method>invokeWSProfile</method> tag.
Uninstalling the product leaves the profiles_root/profile directory with the pctLog.txt file.
Perform the following procedure to produce a clean system.
- Log on as root.
- Run the uninstaller program for the Web server plug-ins for WebSphere Application Server.
If a Web server is configured to run with the application server, uninstall the plug-ins to remove the configuration from the Web server. See Uninstalling the Web server plug-ins for WebSphere Application Server.
- Issue the uninstall command.install_root/_uninst/uninstall
See the description of the uninstall command for more information.
- Use the kill command to kill all Java processes that are 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 that are runningStop all WebSphere Application Server-related processes with the kill -9 java_pid_1 java_pid_2...java_pid_n command.ps -ef | grep java
- Use HP-UX System Administration Manager (SAM) to remove packages.
- Start the SAM utility and verify that your DISPLAY and TERM environment variables are set properly.
- Click Software management.
- Click View installed software.
- Look for WAS entries or IBM HTTP Server entries in the SD list.
- Close the SD list.
- Click Remove local host software.
- Click any of the following instances that display in the SD Remove List:
- IBM HTTP Server
- Click Actions > Mark for remove.
- Click Actions > Remove.
- Click OK in the Remove analysis dialog box.
- Click Logs to display real-time removal of selected packages.
- Click Done when all packages are removed.
- Exit SAM.
- Search for the packages to verify their removal.
Type swlist | grep WS to show packages for WebSphere Application Server.
Package names for Web server plug-ins for WAS areWSPAA60 WSPAA60DGCC WSPAA60DLVC WSPAA60LC WSPAA60WSPC WSPAA60AddBytesHS WSPAA60gskitHP WSPAA60gskitHPC WSPAA60jdkHP
- Type rm -rf /opt/IBM/WebSphere/AppServer/ to remove WAS directories in the /opt/IBM/WebSphere/AppServer installation root. Do not remove installation root directories for products that you intend to keep. Remove all of the profile directories as well.
- Edit the .WASRegistry file.
The file location is the home directory, ~/.WASRegistry.
The .WASRegistry file contains a one-line entry for each WAS product installation.
You can delete the file if there is just one line that identifies the product that you are removing. Otherwise, use a flat-file editor to remove the line that identifies the installation root directory of the product that you are removing. Leave the other lines intact. Do not delete the .WASRegistry file unless you are removing all of the installations listed in the file.
The following example shows a .WASRegistry file for a system with five installations/opt/IBM/WebSphere/AppServer /opt/IBM/P1/AppServer /opt/V6/IBM/WebSphere/AppServer /opt/P2/IBM/WebSphere/AppServer /opt/P3/IBM/WebSphere/AppServer
Example of displaying package names for WebSphere ApplicationServer products
Issue the following commandswlist | grep WSBAA60
The following package name is returnedWSBAA60 6.0.0 IBM WebSphere Application Server
