This procedure cleans an HP-UX 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 installationIdentifier |
Directory location |
install_root |
Default location |
/opt/IBM/WebSphere/ESB or /opt/IBM/WebSphere/AppServer |
Actual location |
|
profile_root |
Default location |
/opt/IBM/WebSphere/ESB/profiles/profile_name or /opt/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
- Log on as root.
- 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.
- Use the HP-UX System Administration Manager (SAM) utility to remove
packages.
- Start the SAM utility and verify that your DISPLAY and TERM
environment variables are set properly.
- Select Software management.
- Select View installed software.
- Look for WebSphere ESB, WebSphere Application Server, or
IBM HTTP Server entries in the SD list.
- Close the SD list.
- Select Remove local host software.
- Select any of the following instances that are displayed in
the SD Remove List:
- WSEAA60
- IBM HTTP Server
- WSBAA60
- WSPAA60
- WSCAA
- gsk7bas
- Select Actions > Mark for remove.
- Select Actions > Remove.
- Select OK in the Remove analysis dialog box.
- Select Logs to display real-time removal of selected
packages.
- Select 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 ESB and WebSphere Application Server.
To
narrow your query to search for
WebSphere ESB packages
only, type the following command:
swlist | grep WSEAA60
- 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.
- 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 installation directory
/opt/IBM/WebSphere/ESB,
issue the following command:
rm -rf /opt/IBM/WebSphere/ESB
- 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.
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.
