Did you copy all the indexes too?
And did you take care of your statistics?
I have copied all my tables from Production database to Test database and now my Test Database seems very slow ?
An idea ?
Wrong forum - this forum is ONLY for questions about sql developer.
Please read the FAQ about how to post a tuning request and the info you need to provide
That info includes:
1. the actual query that is 'slow'
2. the DDL for the tables and indexes involved
3. row counts for the tables and query predicates
4. the execution plan
5. info on any statistics - how and when they were collected
And then repost in the sql and pl/sql forum
