Oracle XE Restore

Question

Hi,
I've a running XE on machine A. OS is Linux. I use achive log and RMAN to backup XE - to start the backup process I use the command '/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/config/scripts/backup.sh' in a cron job.
Now I want to restore the complete XE on Machine B with the command '/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/config/scripts/restore.sh'. On machine B is the same OS as on machine A and XE ist installed. My questions is, which directories from machine A do I have to copy to machine B in order to use the restore.sh script to get the same as on machine A?
Regards,
MS

Sounds like you're almost there, if the database was shut down when that backup was taken.
Easiest method to restore would probably be a controlfile (re)create- get a create controlfile script ready, move the "old" controlfile(s) out of the way, run sqlplus and connect as sysdba, startup nomount, run the create controlfile script, and alter database open should be good to go after adding a new tempfile.
If you don't have a sample controlfile trace to work from, startup that "new" installed instance and (in sqlplus) connect as system (or sys as sysdba) and do a sqlplus `alter database backup controlfile to trace;`
The cloning steps at [http://www.dba-oracle.com/oracle_tips_db_copy.htm] are pretty close except you won't need to make the change to "set database" unless you want to change the db_name (and have also made that change in the initialization file).
If you've added tablespaces those datafiles will also have to be added into the create controlfile script, and you'll probably have to specify the database character set in the create controlfile ... ; statement as well.
