TIBCO iProcess® Engine 11.9.1

# Uninstalling iProcess Engine from a Windows Cluster

If you have installed iProcess Engine in a Windows cluster:

| 1. | Run the following command on each secondary machine in the cluster:

`SWDIR``\mscluster\mscluster -r`

Warning | Do not run this command on the machine where iProcess Engine is installed. If you do so, you will not be able to uninstall iProcess Engine from that machine.

This command removes the following iProcess Engine shared resources and services:

| — | `iProcess` `nodeName` `Process Sentinels` service

| — | `iProcess` `nodename` `Admin Console` service

| — | `NobleNet Portmapper for TCP` service

| — | `iProcess Events64` COM+ application

| — | `iProcess COM+ Bridge` COM+ application

where `nodename` is the node name of this iProcess Engine.

It also removes the port numbers used by the iProcess Engine watcher and worker process sentinels in the `%systemroot%\system32\drivers\etc\services` file.

| 2. | Remove the `Generic Service` resources for the `NobleNet Portmapper` and `Process Sentinels` services for this iProcess Engine using `Cluster Administrator`, see Configuring the Microsoft Windows Cluster for details.

See Microsoft documentation for more information about the `Cluster Administrator` tool.

| 3. | Remove the ODBC data source for this iProcess Engine from each secondary machine in the cluster if you are using a SQL Server database.

| 4. | Uninstall iProcess Engine itself. See Uninstalling iProcess Engine for details.
