Differences Between Managing Resources with dbaascli and the Database API

Learn how Oracle Cloud@Customer automatically synchronizes dbaascli utility parameters and Database Service API properties of Oracle Database instance and Oracle Database Home.

You can manage resources using host tooling such as dbaascli or dbaasapi, or tools based on the Database service API (including the Oracle Cloud Infrastructure Console, SDKs, and the API itself). For the management operations discussed in this topic, if you perform them using dbaascli or dbaasapi, then the updates are not visible in tools based on the Database Service API until the next synchronization operation, which happens every 10 minutes.

The following table lists operations that you perform using dbaascli or dbaasapi, and maps these operations to the related Database Service API parameters:

Operation	Host Tooling Parameters (dbaascli / dbaasapi)	Database Service API Parameters
Creating Database Home	name, DatabaseVersion, dbHomeLocation, createTime	displayName, dbVersion, dbHomeLocation, timeCreated
Updating Database Home	DatabaseVersion, dbHomeLocation	dbVersion, dbHomeLocation
Creating Database	dbName, dbUniqueName, pdbName, characterSet, NlsCharacterSet, dbClass, createTime	dbName, dbUniqueName, pdbName, characterSet, ncharacterSet, dbType, timeCreated
Updating Database	dbHomeId, dbUniqueName, dbClass	dbHomeId, dbUniqueName, dbType

If you terminate a Database Home using the dbaascli or dbaasapi, the status of the Database Home is displayed as Terminated in the Database Service REST API based tools. If you terminate a database, the status of the database is displayed as Failed.
