Hi,

If the database name is not same, you can edit the text version of control file produced in the user_dump_dest directory when you backup the control file to trace. You have to edit the path if the path in your production and test server is not same.

YOu have to copy the datafiles and log files to the test_server. After that run your text version of control files that you just edited.

If the database does not open, just open it with reset logs option.

Thanks
Babu
