Oracle Cloud Infrastructure Documentation

Creating Oracle Database Homes on Exadata DB Systems

You can add Oracle Database Homes (referred to as "Database Homes" in Oracle Cloud Infrastructure) to an existing Exadata DB system by using the Oracle Cloud Infrastructure Console, the API, or the CLI.

A Database Home is a directory location on the Exadata database compute nodes that contains Oracle Database software binary files.

When you create an Exadata DB system, an initial Database Home is created in that system and an initial database is created in that Database Home. After you provision the system, you can create additional Database Homes in the DB system, and add databases to any of the Database Homes.


Avoid entering confidential information when assigning descriptions, tags, or friendly names to your cloud resources through the Oracle Cloud Infrastructure Console, API, or CLI.

You can also add and remove Database Homes, and perform other management tasks on a Database Home by using the dbaascli utility. For information and instructions, see Managing Oracle Database Homes Manually.

Required IAM Policy

To use Oracle Cloud Infrastructure, you must be given the required type of access in a policy  written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. If you try to perform an action and get a message that you don’t have permission or are unauthorized, confirm with your administrator the type of access you've been granted and which compartment  you should work in.

For administrators: The policy in Let database admins manage DB systems lets the specified group do everything with databases and related Database resources.

If you're new to policies, see Getting Started with Policies and Common Policies. If you want to dig deeper into writing policies for databases, see Details for the Database Service.
