The same value should be used on all instances. |
This parameter only affects PDBs. The CDB$ROOT container (CDB root) for a CDB can always schedule and run maintenance tasks during a maintenance window.
The default value is 2. Therefore, by default, two PDBs and the CDB root can run tasks at the same time during a maintenance window.
This parameter can be set only in the CDB root, not in a PDB.
Note:
This initialization parameter is available starting with Oracle Database 12c Release 2 (12.2.0.1).
