hi,
so now another thing to consider.

Is your database running in archive log mode?

from an sql prompt logged in as sysdba, type the command

archive log list;

this will tell you whether you are running in archive log mode or not.
This is important because you can only use RMAN to do an offline backup if archiving is NOT enabled.

an offline backup
RMAN> run {
shutdown immediate;
startup mount;
backup database;
alter database open;
}


Online backups can be more complicated dependent on your company policy of Business Continuity and Business Recovery, but simply you could write a command such as this

RMAN> run {
backup database include current controlfile;
backup (archivelog all delete input);
}



regards

Alan

As far as I know, the statement above is NOT correct.
RMAN can be used for both hot & cold backups; and with cold backups can be used regardless of archive mode or not.
