After running the uninstaller program, complete manual steps to 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. This topic assumes that your user profile has *ALLOBJ and *SECADM special authorities. This topic also assumes that you have run the uninstaller program as described in Uninstalling the product on i5/OS.
The uninstaller program leaves all profiles, including all of the configuration data, applications, and other user data in each profile, unless you use the -OPT removeProfilesOnUninstall="true" parameter on the uninstall command. If you did not include the parameter to delete the profiles and data and you want to delete them, delete them manually.
See Using command line tools for a description of managing configuration files. Back up all applications that are not stored in another location.
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 WebSphere Application Server 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 | /QIBM/ProdData/WebSphere/AppServer/V61/ND | |
| profile_root | /QIBM/ProdData/WebSphere/AppServer/V61/ND/profiles/profile_name | |
| plugins_root | /QIBM/ProdData/WebSphere/Plugins/V61/webserver |
Perform the following procedure to produce a clean system.
The existence of the file causes subsequent installations to fail, indicating an installation is already in progress.
If the file or its directories exist, do the following:
rm –R installLocation
rm –R defaultProfileLocation
The uninstall command might not remove all logs. The logs/uninstall directory contains log files for the uninstallation. Remove the logs and the their directories.
To remove the product directory after uninstallation, run the command:
rm –R app_server_root
You must remove the product directory before you can reinstall to the same location. Do not remove installation root directories for products that you want to keep.
To remove profiles and user data completely after uninstallation, run the command:
rm –R profile_root
Do not remove profiles and user data that you want to keep.
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.
