About Creating Oracle Database Homes on an Exadata Cloud Infrastructure System

You can add Oracle Database homes (referred to as Database Homes in Oracle Cloud Infrastructure) to an existing VM cluster by using the Oracle Cloud Infrastructure Console, the API, or the CLI.

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

Note:

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.

To create a new Database Home in an existing Exadata Cloud Infrastructure instance

To create an Oracle Database home in an existing VM cluster with the Console, be prepared to provide values for the fields required.

1. Open the navigation menu. Click Oracle Database, then click Oracle Exadata Database Service on Dedicated Infrastructure
2. Choose your Compartment.
3. Navigate to the cloud VM cluster or DB system you want to create the new Database Home on:

   • Cloud VM clusters (new resource model): Under Oracle Exadata Database Service on Dedicated Infrastructure, click Exadata VM Clusters. In the list of VM clusters, find the VM cluster you want to access and click its highlighted name to view the details page for the cluster.

   • DB systems: Under Bare Metal, VM, and Exadata, click DB Systems. In the list of DB systems, find the Exadata DB system you want to access, and then click its name to display details about it.

4. Under Resources, click Database Homes.
   A list of Database Homes is displayed.
5. Click Create Database Home.
6. In the Create Database Home dialog, enter the following:
   • Database Home display name: The display name for the Database Home. Avoid entering confidential information.

     Database image: Determines what Oracle Database version is used for the database. You can have databases with different minor versions the same database home. The major versions must remain the same. By default, the latest Oracle-published database software image is selected.

     Click Change Database Image to use an older Oracle-published image or a custom database software image that you have created in advance, then select an Image Type:

     • Oracle Provided Database Software Images: These images contain generally available versions of Oracle Database software.

     • Custom Database Software Images: These images are created by your organization and contain customized configurations of software updates and patches. Use the Select a compartment and Select a Database version selectors to limit the list of custom database software images to a specific compartment or Oracle Database software major release version.

       Note:

       For the Oracle Database major version releases available in Oracle Cloud Infrastructure, images are provided for the current version plus the three most recent older versions (N through N - 3). For example, if an instance is using Oracle Database 19c, and the latest version of 19c offered is 19.8.0.0.0, images available for provisioning are for versions 19.8.0.0.0, 19.7.0.0, 19.6.0.0 and 19.5.0.0.

       Note:

       The custom database software image must be based on an Oracle Database release that meets the following criteria:

       • The release is currently supported by Oracle Cloud Infrastructure.
       • The release is supported by the hardware model on which you are creating the Database Home.

     After choosing a software image, click Select to return to the Create Database dialog.

   • Click Show Advanced Options to specify advanced options for the Database Home.

     • Tags: If you have permissions to create a resource, then you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace. For more information about tagging, see Resource Tags. If you are not sure whether to apply tags, skip this option (you can apply tags later) or ask your administrator.
7. Click Create.

When the Database Home creation is complete, the status changes from Provisioning to Available.
