Learn how to clean a i5/OS® 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 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 and profile_root directories
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 /QIBM/WAS/.ibm/.nif/.nifregistry file
identifies the installation root for all installed WebSphere ESB products.
- The user_data_root/profileRegistry/logs/manageprofiles/profile_create.log file
for each created profile identifies the installation location in the
stanza with the <method>invokeWSProfile</method> tag.
Uninstalling the product leaves the
user_data_root/profileRegistry/logsdirectory.
It also leaves the
install_root/logs directory.
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 both WebSphere 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
- Sign onto the i5/OS system
with a user profile that has *ALLOBJ and *SECADM special authorities.
- In Qshell, go to the install_root directory.
- Remove the subdirectory related to the installation you
are removing. Delete the installation subdirectory and all files and
directories contained in this subdirectory.
Note: The
name of the subdirectory increments with each additional install.
For example, the first installation the directory name is ESB,
then for the second installation is ESB1, and so on.
- Next, go to the user_data_root/profiles directory.
- Remove the subdirectory related to the installation you
are removing. Delete the installation subdirectory and all files and
directories contained in this subdirectory.
Note: The
name of the subdirectory increments with each additional install.
For example, the first installation the directory name is ESB,
then for the second installation is ESB1, and so on.
- Edit the /QIBM/WAS/.ibm/.nif/.nifregistry file.
Remove all entries referring to your installation.
- If this is the last installation of WebSphere ESB being
removed from the system, then you must also delete the i5/OS licensed program registry entry for WebSphere ESB by
issuing the following DLTLICPGM command at the i5/OS CL command prompt.
DLTLICPGM LICPGM(5724I82)
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.
