DbNest provides operating system resource isolation and management, file system isolation, and secure computing for PDBs. The infrastructure is implemented as a Linux-specific package that provides hierarchical containers, called nests. A CDB resides within a single parent nest, while PDBs reside within the individual child nests created within the parent. The isolation and resource management properties of a nest are separate. A full nest includes both isolation and resource management. Alternatively, you can configure a partial nest that includes only resource management.
You can set the following values for this parameter:
-
NONE: Disables dbNest. This is the default value. -
CDB_RESOURCE_PDB_ALL: Enables a resource management-only nest for the CDB and a full nest for each PDB.
