V$LATCHNAME

V$LATCHNAME displays information about decoded latch names for the latches shown in V$LATCH. The rows of V$LATCHNAME have a one-to-one correspondence to the rows of V$LATCH.

Column Datatype Description
LATCH# NUMBER Latch number
NAME VARCHAR2(64) Latch name
DISPLAY_NAME VARCHAR2(64) A clearer and more descriptive name for the latch 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.
HASH NUMBER Latch hash
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
