DBA_HIST_RSRC_PLAN

DBA_HIST_RSRC_PLAN displays historical information about resource plans.

This view contains snapshots of V$RSRC_PLAN_HISTORY.

Column Datatype NULL Description
SNAP_ID NUMBER NOT NULL Unique snapshot ID
DBID NUMBER NOT NULL Database ID for the snapshot
INSTANCE_NUMBER NUMBER NOT NULL Instance number for the snapshot
SEQUENCE# NUMBER NOT NULL A sequential counter that uniquely describes a row. When the instance is restarted, this value is reset to zero.
START_TIME DATE NOT NULL Time that the resource plan was enabled
END_TIME DATE   Time that the resource plan was disabled; NULL if the row contains the current resource plan information
PLAN_ID NUMBER NOT NULL Resource plan ID; NULL if the Resource Manager was disabled
PLAN_NAME VARCHAR2(128) NOT NULL Resource plan name; NULL if the Resource Manager was disabled
CPU_MANAGED VARCHAR2(4) NOT NULL Indicates whether the resource plan has parameters that specify a policy for how the Resource Manager should schedule sessions to manage CPU usage (ON) or whether Resource Manager is not managing CPU usage (OFF)
PARALLEL_EXECUTION_MANAGED VARCHAR2(4)  

State of parallel statement queuing:

  • OFF - Parallel statement queuing is disabled

  • STARTUP - Parallel statement queuing is enabled. This is a temporary state that can occur when an Oracle RAC database is undergoing configuration changes

  • FIFO - Parallel statement queuing is enabled. All parallel statements are managed in a single Oracle RAC FIFO queue

  • FULL - Parallel statement queuing is enabled. All parallel statements are managed in per-consumer group queues according to the current resource plan. This state is used when a resource plan that contains resource allocation directives (MGMT_P*) is enabled.

INSTANCE_CAGING VARCHAR2(4)   Indicates whether instance caging is enabled (ON) or disabled (OFF). Instance caging is enabled if the CPU_COUNT initialization parameter is explicitly modified to a value other than 0 and Resource Manager is enabled.
CON_DBID NUMBER   The database ID of the PDB for the sampled session
CON_ID NUMBER  

The ID of the container that CON_DBID identifies. Possible values include:

  • 0: This value is used for rows containing data that pertain to the entire CDB. This value is also used for rows in non-CDBs.

  • 1: This value is used for rows containing data that pertain to only the root

  • n: Where n is the applicable container ID for the rows containing data
