Doesn't RMAN require Archivelog to be ON ?

No, or only if hot backups are to be done.

Does your database need to be up 24x7?

No It does not need to be up 24x7. A downtime of 12 hours 1 time a month and 4 hours daily is allowed. Its data warehouse.

Frequently, RMAN is the best utility and it is the part of Oracle production. You can configure RMAN with catalog (seperate DB or nocatalog - DB'scontrol_file).

Example with nocatalog
C:\>rman

Recovery Manager: Release 10.2.0.1.0 - Production on Sun May 11 17:53:40 2008

Copyright (c) 1982, 2005, Oracle.  All rights reserved.

RMAN> connect target sys/pwd@meta

connected to target database: META (DBID=1237424567)

RMAN> show all;

using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 1; # default
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP OFF; # default
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK PARALLELISM 1 BACKUP TYPE TO BACKUPSET; # default
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT   'c:\temp\Backup%d_DB_%u_%s_%p';
CONFIGURE MAXSETSIZE TO UNLIMITED; # default
CONFIGURE ENCRYPTION FOR DATABASE OFF; # default
CONFIGURE ENCRYPTION ALGORITHM 'AES128'; # default
CONFIGURE ARCHIVELOG DELETION POLICY TO NONE; # default
CONFIGURE SNAPSHOT CONTROLFILE NAME TO 'C:\ORACLE\PRODUCT\10.2.0\NEO\DATABASE\SN
CFMETA.ORA'; # default

RMAN>


Example with backup Level0
RMAN> shutdown immediate

database closed
database dismounted
Oracle instance shut down

RMAN> startup mount

connected to target database (not started)
Oracle instance started
database mounted
