oracle rename MISSINGnnnn files
Hi, I am learning on how to refresh databases by copying the production datafiles to the test server. After we move the read write files to the test server, alter the control file and open up the database, we need to rename the missing files. The missing files will be having the name "Missingnnnn". I want to know how do we know which missing file is related to which datafile so that I can rename it correctly.
