Oracle Dynamic Performance Views


Oracle dynamic performance views (v$) are built on the virtual tables ($x). The views (v$) are much more useful than the virtual tables ($x). To get a listing of all them use the following query:

select
    NAME
from 
    V$FIXED_TABLE
where 
    TYPE = 'VIEW';

Some of the most useful views include:

  • v$database Details about the nature and state of the database
  • v$transaction What transactions are currently uncommitted
  • v$session What users have logged on
  • v$controlfile Names and locations of all control files
  • v$logfile Names and locations of all online redo logs
  • v$datafile Names and locations of all data files
  • v$instance Details about the nature and state of the instance
  • v$sqltext What queries are users issuing
  • v$process What background and server processes are running

Global dynamic performance views have the prefix gv$. They are viewing across all instances when using a real application cluster (RAC) configuration.
