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 the IORM vault plan. 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.
