9.8.2 IORM Support for CDBs and PDBs

Oracle Database 12c Release 1 (12.1) supports a multitenant architecture. In a multitenant architecture, a container is a collection of schemas, objects, and related structures in a Oracle Multitenant container database (CDB) that appears logically to an application as a separate database. In a CDB, administrators can create multiple pluggable databases (PDBs) to run their workloads. In a CDB, there are multiple workloads within multiple PDBs competing for shared resources.

By using CDB plans and PDB plans, I/O Resource Management (IORM) provides the ability to manage I/O resource utilization among different PDBs as well as manage the workloads within each PDB.

Oracle Database 12c Release 1 (12.1) supports IORM prioritization to manage I/O resource utilization among different PDBs as well as manage the workloads within each PDB.
