2.3 AWR_ROOT_* Views

The AWR_ROOT views show the AWR data stored only on a CDB root. In general, the AWR_ROOT views are equivalent to the DBA_HIST views.

When the AWR_ROOT views are accessed from a CDB root, they show the AWR data specific to the CDB root.

When the AWR_ROOT views are accessed from a PDB, they show the AWR data specific to that PDB.
