Oracle EE slower than Oracle XE

edited Apr 3, 2013 7:21AM in Database Tuning (MOSC) 6 commentsAnswered
Dear community,
I would like some advice on which parameter to check on my enterprise db to understand why it is slower than XE db.

I have a query:
       SELECT DT.TREE_ID PARENT_ID,
              DT.NAME PARENT_NAME,
              DT.UNIVERSE AS UNIVERSE,
              DT.TYPE AS TYPE,
              CONNECT_BY_ROOT dt.TREE_ID,
              CONNECT_BY_ROOT dt.name,
              LEVEL - 1 DISTANCE
         FROM TREES DT
   START WITH DT.TYPE = 'FIELD'
   CONNECT BY NOCYCLE DT.TREE_ID = PRIOR DT.PARENT_ID
   
As I have 2 possible values in TYPE (FILED or NODE), I wanted to test a bitmap index (which is not possible on XE). So I created everything on a dev EE db to see if a bitmap index would be good.

Howdy, Stranger!
