STATISTIC#

NUMBER

Statistic number

Note: Statistics numbers are not guaranteed to remain constant from one release to another. Therefore, you should rely on the statistics name rather than its number in your applications.

NAME

VARCHAR2(64)

Statistic name. Names that appear in this column remain stable across Oracle Database releases, and they can be relied on by customer scripts.

CLASS

NUMBER

A number representing one or more statistics classes. The following class numbers are additive:

• 1 - User

• 2 - Redo

• 4 - Enqueue

• 8 - Cache

• 16 - OS

• 32 - Real Application Clusters

• 64 - SQL

• 128 - Debug

STAT_ID

NUMBER

Identifier of the statistic

DISPLAY_NAME

VARCHAR2(64)

A clearer and more descriptive name for the statistic that appears in the NAME column. Names that appear in the DISPLAY_NAME column can change across Oracle Database releases, therefore customer scripts should not rely on names that appear in the DISPLAY_NAME column across releases.

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
