SolutionFrom your post I understand that your production database is abc. And you have a development database called dfe and you wanted to refresh the dev data with prod data.
Then in that case the simple option for you will be to export the schema data from prod and then import into dev database. You need not worry about the datebase name change or datafile name / location change.
But if you still wanted to refresh dev data from prod by copying (to the dev location) the datafiles and archivelogs from a backup and reccovering then you will have to re-create the control file with the dev database name. In this case you will shutdown the dev database and delete the datafiles and then copy them from the backup.

Re: Restoration Problems
It depeneds on the type of backups you have. Do you have a full cold backup of your prod database or a hot backup.
If you are refreshing the dev with prod from a full cold backup then all you do restore the files from backup into your dev server and that will be a consistent recovery.
If you have hotbackup and then apply archivelogs to recover to a particular time then it will be recovery to that time.
I still feel export / import if best for you if you are looking at refreshing the data alone. Simple and best approach, but may take some time depending on the db size.

Re: Restoration Problems
Try using copy functioanlity or import/export functionality of Oracle DB. I feel, that will help you to do a refresh.

Re: Restoration Problems
if you take a hot backup of your production database, you can proceed as follows:
o restore the datafiles
o use the CREATE CONTROLFILE statement but use RESETLOGS
o use the RECOVER DATABASE USING BACKUP CONTROLFILE command
o when you've applied all of the archives -- alter database open resetlogs
(that'll create the new redo files for you)
and indeed you can modify the location of the datafiles in the "create controlfile" script.
hope this helps!
kind regards
