Learn how to clean a HP-UX system if uninstallation of WebSphere® ESB fails.
After running the uninstallation program, go through these manual
steps to remove registry entries that can prevent you from reinstalling
the product into the original directory.
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 completed successfully. 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.
For details on default directory locations see Default installation directories for the product, profiles, and tools.
The
installation wizard and the Profile Management Tool let you specify
your own locations for installation root directories. Examine the
following files to determine the actual locations:
- The /opt/.ibm/.nif/.nifregistry file identifies the installation
root for all installed WebSphere ESB products;
it also looks for all WebSphere Application
Server products.
- The install_root/logs/manageprofiles/profile_name_create.log file
for each created profile identifies the installation location in the
stanza with the invokeWSProfile method.
Uninstalling the product leaves the
profile_root directory,
including the
profile_root/logs file, where
profile_root represents
the installation location of the profile. It leaves the
install_root/logs directory
as well.
About 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 bothWebSphere ESB and WebSphere Application Server
or WebSphere Application
Server Network 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.
Procedure
- Log on as the same user ID who installed the product.
- Use the kill command to stop 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 with the /usr/sbin/sam command.
- Verify that your DISPLAY and TERM environment variables
are set properly.
- Click Software management.
- Click View installed software.
- Look for WebSphere ESB or WebSphere Application Server
entries in the SD list.
- Close the SD list.
- Click Remove local host software.
- Select any of the following instances that are displayed
in the SD Remove List:
- Select .
- Select .
- 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 ESB and WebSphere Application Server.
To
narrow your query to search for
WebSphere ESB packages
only, type the following command:
swlist | grep WSEAA62
- Remove the installation root directory.
Type
rm
-rf install_root to remove
WebSphere ESB. 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
- Use the installRegistryUtils command
to examine the installation locations for all installed WebSphere server products and remove the
desired products from the installation registry.
- Clean the .nifregistry file. To clean this file:
- Backup the .nifregistry file.
- Open the .nifregistry file in a text editor (ensure
that line wrapping is turned off).
- Search and delete all lines that have the <INSTALL_LOC>
and <PRODUCT_ID> in them where <INSTALL_LOC> is the installation
location where you have a failed uninstallation and <PRODUCT_ID>
is the product offering ID of the product that you are trying to
uninstall.
- Save the .nifregistry file and close the text editor.
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.
What to do next
After you have cleaned your system, go to Installing the software to
choose an installation procedure.
