如何找到已安装的Oracle版本？

Question

I have inherited an installation of Oracle 11G on CentOS. I know the version by running:

SELECT * FROM v$version;

Result: Oracle Database 11g Release 11.2.0.2.0 - 64bit Production

However, I am trying to find the edition of Oracle installed for licensing purposes. Everyone keeps telling me it is a 'Lite' version...
The Oracle documentation tells me there are 5 editions:

From everything I have read when googling this, people say that if the results from select * from v$version does not say Enterprise , then it is Standard . I do not believe that I can go by that as there are 5 editions and two of them are separate types of Standard Edition. I need to know the exact edition installed.

Does anyone have any idea who I can determine what exact edition is installed?

Thanks!

Answer 1

Running this on 11g Enterprise

select * from v$version where banner like 'Oracle%';

shows

If it doesn't say Enterprise or XE then it is Standard
