1.26 AUTOTASK_MAX_ACTIVE_PDBS

AUTOTASK_MAX_ACTIVE_PDBS enables you to specify the maximum number of PDBs that can schedule automated maintenance tasks at the same time (during a maintenance window).

Property Description

Parameter type

Integer

Default value

2

Modifiable

ALTER SYSTEM

Modifiable in a PDB

No

Range of values

0 to the number of PDBs in the CDB

Basic

No

Oracle RAC

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.
