Switching a dynamic domain manager for a Z controller

As a normal behavior, the dynamic domain manager for a Z controller works by having both the server and processes up and running, while the backup dynamic domain manager for a Z controller works with the processes that are running and the system that is down. You might have to switch the dynamic domain manager for a Z controller to a backup workstation because, for example, the system running the current workstation goes down.

To switch the dynamic domain manager for a Z controller to the backup workstation, perform the following procedure:

Stop the server on the dynamic domain manager for a Z controller by issuing the following command:
On Windows
```
stopAppServer.bat
```
On UNIX
```
stopAppServer.sh
```
On the backup dynamic domain manager for a Z controller, run the following command:
On Windows
```
startZosDDM.bat -dbUsr db_user -dbPwd db_user_pwd
```
On UNIX
```
startZosDDM.sh -dbUsr db_user -dbPwd db_user_pwd
```
where:

dbUsr db_user

The user that has been granted access to the HCL Workload Automation for Z tables on the database server.

dbPwd db_user_pwd

The password for the user that has been granted access to the HCL Workload Automation for Z tables on the database server.
On the backup dynamic domain manager for a Z controller, start the server by running the following command:
On Windows
```
startAppServer.bat
```
On UNIX
```
startAppServer.sh
```
