This task describes how to uninstall the product on an AIX platform.
Before you begin
Use the following procedure to remove all remnants of a WebSphere Application Server product. This produces a clean system that allows you to reinstall the product. Before you begin, verify that you are removing only the product instance that you intend to remove and not coexisting products, or products that you might have migrated and do not intend to delete. It is important to know the installation root directory for the product instance that you are removing.
Why and when to perform this task
Use this procedure to uninstall WebSphere Application Server products. Uninstall the products in the following sequence when you are uninstalling more than one product:
One of the ways that this procedure completely uninstalls the product is by completely deleting the installation root directory for the product. References to the directory are abbreviated install_root in some of the steps. The default install_root for WebSphere Application Server is the /usr/WebSphere/AppServer directory.
Default installation
roots for the Enterprise product are:
Steps for this task
If there are Java processes running that are not related to WebSphere Application Server products, and it is not possible to stop them, stop all WebSphere Application Server product-related processes. Use the following command to determine all processes that are running:
ps -ef | grep javaStop all WebSphere Application Server-related processes with the kill -9 java_pid_1 java_pid_2...java_pid_n command.
Do not remove IBM WebSphere MQ packages if you have installed IBM WebSphere MQ as a separate product.
Do not remove embedded messaging packages if you intend to leave the embedded messaging feature installed on the machine.
If you do intend to remove WebSphere MQ or embedded messaging packages, include them in the commands you are running to remove packages. For example, type these commands to search for, and remove related packages:
You can also run the following command from root to remove the embedded messaging feature from your system:
installp -u wemps mqjava mqmReply y[es] to all prompts.
However, do not remove any mqm or mqjava packages if you have installed IBM WebSphere MQ separately or if you have other WebSphere Application Server products that use the embedded messaging feature.
The examples below show typical package names that might appear on a system with the base WebSphere Application Server product.
If no packages appear when using these commands, skip the next step.
Do not remove IBM WebSphere MQ packages if you have installed IBM WebSphere MQ as a separate product, or if you have installed the embedded messaging feature and other product instances are using the feature.
Do not remove IBM WEMPS packages unless you are certain that there is no embedded messaging data to preserve.
If you installed IBM WebSphere MQ as a separate product on this host to use as the messaging provider, and if you do not want to continue using WebSphere MQ, you can uninstall the product as described in the WebSphere MQ information.
Do not delete or rename the vpd.properties file because the InstallShield for MultiPlatforms (ISMP) program uses it for other products that it installs. If the vpd.properties file has no other entries, you can delete the file.
Results
When you finish, the product is completely uninstalled. You are now ready to reinstall. Reinstalling successfully into the same directory is the final indicator of success in removing the original product.Example
