Note:
The value of this parameter in CDB$ROOT (the root of a CDB) has no effect in the root. Automated maintenance tasks are always run in the root, regardless of the setting of this parameter.
By default, the value of ENABLE_AUTOMATIC_MAINTENANCE_PDB
is true
in CDB$ROOT (the root container in the CDB) and in the individual PDBs in a CDB. This means that by default, automated maintenance tasks are run for the CDB root and all the PDBs in the CDB.
When you change the value of ENABLE_AUTOMATIC_MAINTENANCE_PDB
in the CDB root, the new value takes effect in the root and in all the PDBs in the CDB.
Therefore, if you change the value of ENABLE_AUTOMATIC_MAINTENANCE_PDB
in the CDB root to false
, the value of ENABLE_AUTOMATIC_MAINTENANCE_PDB
is also changed to false
in all of the PDBs in the CDB.
You can also change the value of ENABLE_AUTOMATIC_MAINTENANCE_PDB
in any of the individual PDBs in a CDB, and the value that is set for each individual PDB will be honored. This enables you to enable or disable automated maintenance tasks for individual PDBs.
