The failover scenario consists of updating parameters in a master database. Once the requirements for the failover scenario are satisfied, the failover scenario is executed. After execution, the acting master instance will change.


The following parameters need to be updated:

1. Navigate to **Administration** > **System Config Management**.
2. Set the following parameters and Save:

| **Parameter name**                                  | **Value**      | **Definition**                                                                                                     |
| --------------------------------------------------- | -------------- | ------------------------------------------------------------------------------------------------------------------ |
| **netright.job.master.instance.name**               | Instance name  | Master instance parameter for the controller region. It must be the same as the one defined in netright.properties |
| **netright.job.master.instance.name.$region\_name** | Instance name  | Master instance parameter for the controlled region. It must be the same as the one defined in netright.properties |
