I’ve just done a quick check in 11.1.0.6.
The table is of duration “SYS$SESSION”, i.e. it’s “on commit preserve rows”.

This means the temporary extent your session has been assigned for the table will only be released when your session ends, or when you issue “truncate table …”.

The TO lock disappeared when I executed:

truncate table mdsys.SDO_GEOR_DDL__TABLE$$;

I know exactly what you’re talking about:

Installing it the default way no matter what gets installed just get it up and running – the [Next] button is your friend! And then you have a lot of things going on in the background which you won’t need.

But I have one question here: When gets the lock released? As drop table is a DDL statement there happens an implicit commit, right? So is Oracle Spatial taking care of the lock release?
