How can I check the version of a Liferay instance?

Question

I have several instances of Liferay Portal (bundled with Apache Tomcat 5.5.x/6.x) and I need to know how to check the version of those Liferay instances

Answer 1

If you can get the database, which is one:

select * from Release_;

there is a column called buildNumber, it can have a value like 6005 or 5203

The other way, with the apache tomcat startup, you will see in the catalina.out log file: Starting Liferay Portal Community Edition 6.0.5 CE (Bunyan / Build 6005 / August 16, 2010)
