1-  it does level 0 backup of database  including the  control file , spfile every  week on saturdays

2- it does incremental level 1 backup everyday

3- it does archivelog backup everyday

for review

Why do you allocate different directories for the level 0 backup than for the level 1 backups? This is needless complexity.

YOu don't need separate run blocks for archivelogs and/or controlfile/spfile.  This is needless complexity

I accomplish everything you want with a single shell script.  Here's the core of it:

#!/bin/shORACLE_SID=$1inclvl=$2logfile=$3
ORAENV_ASK=NOsource oraenvrman target /  <<EOF >> $logfileset echo ondelete force noprompt obsolete;backup as compressed backupset incremental level $inclvl database tag ${ORACLE_SID}_db_bkup plus archivelog delete all input /tag ${ORACLE_SID}_arch_bkup;
list backup;
EOF
