- 2. Oracle Database 11g Architecture Before we talk about Multitenant Architecture we must know about Non-Multitenant Architecture
- 3. Oracle Database Multitenant Architecture A multitenant database provides the capability for the oracle database to function as a container database (CDB) A container database provides the ability for the oracle database to include from zero, one , or many unique and isolated database environment called pluggable databases (PDBs) Each environment can have its own set of schemas , schema object, users and so on To the application once connected to a given PDB the PDB looks just like a non- CDB
- 4. Container and Pluggable Databases A container is logical collection of data or metadata within the multitenant architecture A multitenant container database or CDB include zero, one, or many customer created pluggable databases A pluggable databases or PDB is a portable collection of schema, schema objects, and non-schema object that appears to an Oracle Net Client Application as a non- CDB Multitenant Architecture allows many PDBs inside of a single CDB The maximum number PDBs that you are allowed to create in CDB depends on licensing policy (the maximum number is 4098 or 5254)
