Learn to create Oracle Database Homes on Exadata Cloud@Customer.
About Creating Oracle Database Homes on an Exadata Cloud@Customer 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 compute nodes that contains Oracle Database software binary files.
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
Required IAM Policy for Creating Oracle Database Homes
Review the identity access management (IAM) policy for creating Oracle Database homes on Oracle Exadata Cloud@Customer Systems.
- An individual statement written in the policy language
- A collection of statements in a single, named "policy" document, which has an Oracle Cloud ID (OCID) assigned to it
- The overall body of policies your organization uses to control access to resources
A compartment is a collection of related resources that can be accessed only by certain groups that have been given permission by an administrator in your organization.
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 a software development kit (SDK), a command-line interface (CLI), or some other tool. If you try to perform an action, and receive a message that you don’t have permission, or are unauthorized, then 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, then see "Getting Started with Policies" and "Common Policies". If you want to dig deeper into writing policies for databases, then see "Details for the Database Service".
