Creates a new Data Guard association. A Data Guard association represents the replication relationship between the specified database and a peer database. For more information, see Using Oracle Data Guard.

All Oracle Cloud Infrastructure resources, including Data Guard associations, get an Oracle-assigned, unique ID called an Oracle Cloud Identifier (OCID). When you create a resource, you can find its OCID in the response. You can also retrieve a resource's OCID by using a List API operation on that resource type, or by viewing the resource in the Console. For more information, see Resource Identifiers.

Optional Parameters

--database-software-image-id [text]

The database software image OCID

--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id --> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our "using CLI with advanced JSON options" link:

--peer-db-home-id [text]

The OCID of the DB Home to create the standby database on.
