Oracle Database 19c: Multitenant Architecture

Oracle introduced the multitenant architecture in version 12.1.0.2 as an available option, but after 19c, creating a multitenant database is the only option for a new database. Bob shows how to manage multitenant databases on the same server, how to create the CDB, create a PDB from the seed database, and clone a PDB to the same or another container. The multitenant architecture also has several new options when backing up and recovering databases and individual tables with the existing RMAN utility, so Bob explains new RMAN scenarios and details when to back up just the CDB root, the entire CDB, or individual PDBs. He covers how to create and manage a special type of PDB called an application PDB and shows how to leverage the versioning capabilities included with application containers.
