Info
We have not shown Oracle installation here since its out of scope. The installation can be performed the same way as any on-premise installation. Please refer to the Oracle documentation installation guide based on the version you would like to install.

We will see in detail how to configure the standby database on ODA using Dbvisit standby v11.7.0.
For that first, we need to create an empty database using ODA with the same db_name and db_unique_name as that of primary. This will register your standby database in ODA. Once registered, delete standby database-related files. We will use Dbvisit Standby v11.7.0 to create the standby database in ODA.

2. Create a Database on ODA

Overview of the system information

Image Modified

Go to the Database tab and click on Create Database

Image Modified

Fill in the details here and click on Create. Please provide the DB Name as TESTDBV same as primary db_name. You can either create a new Oracle home or use an existing Home. Storage type can be ASM or ACFS. Here we have chosen ASM

Image Modified

Database TESTDBV complete.

Image Modified

Next step, Shut down the standby database and remove the database-related files. Here we are removing datafiles under ASM disk group +DATA and recovery files under +RECO
