List Installed Components

Oracle Database Tips by Donald BurlesonSeptember 26, 2015

Question: What queries can I issue to see the installed components and features of Oracle?

Answer: Oracle provides several views (dba_registry and v$option) that display the installed options within the database. These two queries will display the installed features of an Oracle database instance:

set pages 999

col c1 heading 'feature' format a45
col c2 heading 'times|used' format 999,999
col c3 heading 'first|used'
col c4 heading 'used|now'

select
   name c1,
   detected_usages c2,
   first_usage_date c3,
   currently_used c4
from
   dba_feature_usage_statistics
where
   first_usage_date is not null;

select
   comp_name,
   version
from
   dba_registry
where
   status = 'VALID';

select
   parameter
from
   v$option
where
   value = 'TRUE'
order by
   parameter;
