 Hi Guys,

Need your help...What is the command to backup an ONLINE Oracle
database?

In Ms SQL the command goes like... backup database to device eg disk=d:\temp>

other than ALTER command for Oracle... ALTER begin
>backup; copy the files ; ALTER end backup is there a single command I can use?

How big is the database? You can use export and import utilities for backup and restore.

You can just type exp on your command prompt and that will take you in the right direction.

Hope it helps.

Hi Naresh,
I would like to tell you that no matter how big your database is, tablespace is the unit of backup in case of online backup. You can either take the tablespace offline and then by copy command you copy all related datafiles, or you can bring the tablespace in backup mode while it is still online, copy all datafiles, then go for logswitch and then take the backup of archieved redo log files too.
For logical backup you use export utility.
I hope my suggestion would be of some use.
All the best......
