1.2.19 Resource Management

Resource management governs how various storage resources are consumed. Exascale resource management works in conjunction with existing Exadata I/O Resource Management (IORM) and Oracle Database Resource Manager (DBRM) capabilities.

Exascale resource management is implemented in a hierarchical manner:

• Firstly, inter-vault resource management governs how resources are allocated to different vaults using Exadata IORM.

• The resulting resource allocation for each vault is further divided among the different databases and block volumes using intra-vault resource management with Exascale resource profiles.

• Finally, the resulting resource allocation for each database is divided among PDBs and consumer groups using intra-database resource management with DBRM definitions.

The following topics describe each of these areas in greater detail.
