Step by Step RMAN configuration for full hot backup daily

Question

Dear experts,
i am new to oracle RMAN , i have gone through couple of RMAN guides for configuration ,
i have oracle e-business suite (R12.1.1) and database is ( 11.1.0.7) on red hat enterprise linux 5.3 . All of this is 64 bit.
i have a database about 175 gb which is as usual growing day by day as data entry is taking place.
Untill now we have a cold backup strategy in the midnight 3 am a script down the database and make abc.tar.gz file of 25 gb approx. . This process takes about 100 minutes. But now due to new sales system we want our database up 24/7 .
So we want to configure RMAN hot backup.
I want to take backup on disk.
daily full hot backup.
backupsets
currently database is in no-archivelog
plz help me to proceed with this .

Dear all,
i am using this script for my full hot backup ,
run
allocate channel c1 device type disk format '/opt/R12Backups/rman/%U';
allocate channel c2 device type disk format '/opt/R12Backups/rman/%U';
crosscheck backup;
BACKUP DATABASE FORMAT '/opt/R12Backups/rman/proddb_%u_%p_%c';
sql 'alter system switch logfile';
BACKUP ARCHIVELOG ALL DELETE INPUT FORMAT '/opt/R12Backups/rman/archlog%U';
DELETE NOPROMPT OBSOLETE REDUNDANCY =1 device type disk;
DELETE NOPROMPT EXPIRED BACKUPSET OF DATABASE device type disk ;
BACKUP AS COPY CURRENT CONTROLFILE FORMAT '/opt/R12Backups/rman/copy_of_cf_%U';
BACKUP SPFILE FORMAT '/opt/R12Backups/rman/spfile_%U';
release channel c1;
release channel c2;
1.please tell me that it is covering all aspects of a backup . Can i do complete recovery with this backup in case of disaster?
Define "all aspects".
2. i only get database and controlfile backup at my location. There is no backup of archivelogs , What happened with
that ?Without seeing the output that rman generated from running the above block, and without seeing all of the persistent rman settings, it is impossible to diagnose anything. I will say that your script looks overly complex.
Just to give you a point of comparison, here's my setup. First the persistent rman settings. Take note of anything that is NOT marked as "default";
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 7 DAYS;
CONFIGURE BACKUP OPTIMIZATION ON;
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default
CONFIGURE CONTROLFILE AUTOBACKUP ON;
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '%F'; # default
CONFIGURE DEVICE TYPE DISK BACKUP TYPE TO COMPRESSED BACKUPSET PARALLELISM 1;
CONFIGURE DATAFILE BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE 'SBT_TAPE' TO 3;
CONFIGURE ARCHIVELOG BACKUP COPIES FOR DEVICE TYPE DISK TO 1; # default
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 '/ora00/app/oracle/product/10.2.0/db_1/dbs/snapcf_vlnxora1.f'; # defaultAnd here is my basic "full backup" script
[oracle@vmlnx01 bin]$ cat rman_full.scr
connect target /
show all;
run {
  backup incremental level 0 database tag='bkup_vlnxora1_full';
  backup archivelog all not backed up 2 times tag='bkup_vlnxora1_arch';
  delete noprompt archivelog all backed up 2 times to device type disk;
list backup summary;
report obsolete;
quit
