Ive seen this come up a few times, someone has webcenter installed, but isnt sure *exactly* which version of webcenter 11g they have installed..

Well its quite easy...

1. Connect to sqplus as SYSDBA to the WebCenter database
2. Run the following query to get the WebCenter schema:
   

   select username from all_users where username like '%WEBCENTER%';
   

   Take note of the WebCenter username so you can use in next query.

3. Run the following query to get the WebCenter version:
Replace: - With the username from previous query.


select version
from .WC_REPOSITORY_VERSION;

Also worth noting this is all documented in support note Note 1053606.1 available at metalink
