This task describes how to uninstall the product on an HP-UX 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 /opt/WebSphere/AppServer directory.
The default directory for IBM HTTP Server is /opt/IBMHttpServer.
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.
You can use a ps -e | grep #AMQ_COMMAND#' command structure to specify the command for amq to find each amq pid.
If you do intend to remove embedded messaging feature packages, use HP-UX System Administration Manager (SAM) to remove packages for the instance that you intend to delete. Then search for the packages to verify their removal.
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.
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.What to do next
After uninstalling the product, see Installing WebSphere Application Server products to begin planning your next installation.
