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.
`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
