    Hot backups are taken on the tablespace level.

    At SQL plus or Server manager prompt: issue the command:

    ALTER TABLESPACE ts_name start backup;

    Now assuming you are not using RMAN, use the OS utilities to copy all the datafiles belonging to that particular tablespace. Once you do that issue the command:

    ALTER TABLESPACE ts_name END backup;

    The Command is

    Alter Tablespace <TABLESPACE NAME> Begin backup;

    Alter Tablespace <TABLESPACE NAME> End Backup;

    As mentioned above , hot backup is taken tablespace by tablespace:

    steps:

    1. take a list of tablespaces and corresponding datafiles you want to take backup.

    2. Issue the command ALTER TABLESPACE tablespace name BEGIN BACKUP;

    3. Copy all the datafiles corresponding to this tablespace to the backup drive.

    4. Issue the command ALTER TABLESPACE tablespace name END BACKUP;

    Repeat the above for all the tablespaces. It's advisable to take backup at the time of low db activity..
