8.191 V$RSRC_PLAN

V$RSRC_PLAN displays the names of all currently active resource plans.

Column Datatype Description

ID

NUMBER

Resource plan ID (a unique number, consistent across database shutdowns and startups). This is also the data dictionary object ID.

NAME

VARCHAR2(32)

Name of the resource plan

IS_TOP_PLAN

VARCHAR2(5)

Indicates whether the resource plan is the current top plan (TRUE) or whether the resource plan is a subplan of the current top plan (FALSE)

CPU_MANAGED

VARCHAR2(3)

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)

INSTANCE_CAGING

VARCHAR2(3)

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.

PARALLEL_SERVERS_ACTIVE

NUMBER

Total number of active parallel servers on the instance

PARALLEL_SERVERS_TOTAL

NUMBER

The value of PARALLEL_SERVERS_TARGET for the instance. Parallel statements are queued if the total number of active parallel servers exceeds this value.

PARALLEL_EXECUTION_MANAGED

VARCHAR2(32)

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.

  • DISABLED - Parallel statement queuing is disabled. This state can occur when memory is unavailable for use by parallel statement queuing in the System Global Area (SGA). Restart the Oracle instance to re-enable parallel statement queuing.

For an Oracle RAC database, only the instance running as master Database Resource Manager (DBRM) shows the correct state of parallel statement queuing. All other instances default to the value FULL. A single instance database always shows the correct value for this field.

CON_ID

NUMBER

The ID of the container to which the data pertains. 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

DIRECTIVE_TYPE

VARCHAR2(32)

The type of directive used by this PDB:

  • DEFAULT_DIRECTIVE: The default plan directive

  • PDB: A PDB directive

  • PROFILE: A profile directive

SHARES

NUMBER

Resource allocation for this PDB, expressed in shares

UTILIZATION_LIMIT

NUMBER

Maximum percentage of the container's resources allowed for this PDB

PARALLEL_SERVER_LIMIT

NUMBER

Maximum percentage of the parallel target the PDB can use before queuing subsequent parallel queries

MEMORY_MIN

NUMBER

Minimum memory guaranteed for this PDB, expressed in a percentage

MEMORY_LIMIT

NUMBER

Maximum memory allowed for this PDB, expressed in a percentage

PROFILE

VARCHAR2(32)

The value of the DB_PERFORMANCE_PROFILE initialization parameter for this PDB

The resource plan with CON_ID=ROOT is the CDB resource plan.
