Note: If your RDBMS is based on Oracle, run the showDataSource wastools command before uninstalling the master domain manager and take note of the net service name used for your database.

1. Shut down all HCL Workload Automation operations and processes

On a system prompt, go to the HCL Workload Automation installation path.
Set the environment by running the twa_env.cmd command.
Stop the dynamic agent by running the ShutDownLwa command.
Stop netman, conman and their child processes by running the conman “shut;wait” command.

As an alternative, you can also stop all processes by shutting down the related HCL Workload Automation and IBM WebSphere Application Server services from the services panel.

2. Delete the HCL Workload Automation profile on WebSphere Application Server

Go to the bin subdirectory under the installation path, for example C:\Program Files\IBM\WebSphere\AppServer\bin, and run the command:
```
manageprofiles.bat –delete –profileName your_profile_name
```
Check the name of the profile used by your HCL Workload Automation instance by running these steps:
1. Go to the C:\WINDOWS\TWA directory. This directory contains several files, one for each HCL Workload Automation instance that is installed.
2. Look for the file whose properties include the path of the profile to delete. The profile_name property contains the name of the profile to delete.
Verify in the log file that the profile was deleted successfully.
Delete manually the TWSProfile from the WebSphere Application Server directory under the installation path.

When you finished, check that the following services are no longer listed in the active services for the TWS_user:

Workload Scheduler
Netman
Token service

Look for the properties file that applies to the HCL Workload Automation instance to remove.
Delete that properties file and the file with the same filename and extension .ext.
Delete the C:\Windows\teb directory.

```
If you see an entry named your_db_name associated to the HCL Workload Automation instance, run the command:
```
drop db your_db_name
```
If you see an entry named your_db_name_DB associated to the HCL Workload Automation instance, run the command:

If the master domain manager was installed on the DB2 client, run steps 1 and 5 also on the system where the master domain manager is installed.
