Managing Exadata Databases

When you launch an Exadata DB system, an initial database is created in that system. You can create additional databases in that DB system at any time by using the Console or the Oracle Cloud Infrastructure API.

When you add a database to an Exadata DB system, the database versions you can select from depend on the current patch level of that DB system. You might have to patch your DB system to add later database versions. For information about patching the DB system, see Patching an Exadata DB System.


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 databases, and perform other management tasks on a database by using command line utilities. For information and instructions on how to use these utilities, see Managing Exadata Databases 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.


See Known Issues for information about using the Oracle Cloud Infrastructure Console, API, or CLI to manage Exadata DB systems if your system was provisioned before June 15, 2018.

Using the Console

To create a new database in an existing Exadata DB system
To terminate a database

Using the API

For information about using the API and signing requests, see REST APIs and Security Credentials. For information about SDKs, see Software Development Kits and Command Line Interface.

Use these API operations to manage databases.

For the complete list of APIs for the Database service, see Database Service API.

Changing the Database Passwords

The password that you specify in the Database Admin Password field when you create a new Exadata DB system or database is set as the password for the SYS, SYSTEM, TDE wallet, and PDB Admin credentials. Use the following procedures if you need to change passwords for an existing database.

Note that if you are enabling Data Guard for a database, the SYS password and the TDE wallet password of the primary and standby databases must all be the same.
