HI Experts,

We take RMAN backups daily night at around 10 PM EST as per below mentioned script .

NLS_DATE_FORMAT='dd-mon-yyyy hh24:mi:ss';export NLS_DATE_FORMAT
ORACLE_SID=cfp106;export ORACLE_SID
ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/db_1;export ORACLE_HOME

LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH;export LD_LIBRARY_PATH
rman target / log=/util/dba/cfp106/reports/cfp106_rman_hot_backup_`date +%Y%m%d%H%M%S`.log <<EOF
set echo on;
RUN {

}
exit
EOF

In morning at around 04 AM EST , we push the backups to tape using below mentioned script .

NLS_DATE_FORMAT='dd-mon-yyyy hh24:mi:ss';export NLS_DATE_FORMAT
ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/db_1;export ORACLE_HOME
ORACLE_SID=cfp106;export ORACLE_SID
PATH=$ORACLE_HOME/bin:$PATH;export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH;export LD_LIBRARY_PATH
rman target / log=/util/dba/cfp106/reports/cfp106_rman_backups_totape_`date +%Y%m%d%H%M%S`.log <<EOF
set echo on;
run {
CONFIGURE CHANNEL DEVICE TYPE sbt PARMS 'ENV=(TDPO_OPTFILE=/opt/tivoli/tsm/client/oracle/bin64/tdpo_CFP106_ORA.opt)';
CONFIGURE DEVICE TYPE sbt PARALLELISM 1;
BACKUP DEVICE TYPE sbt BACKUPSET ALL NOT BACKED UP SINCE TIME 'SYSDATE-35/24';
}
.

Issue here is Inspite of running DELETE NOPROMPT OBSOLETE RECOVERY WINDOW OF 10 DAYS DEVICE TYPE DISK , disk backup pieces are not getting removed . Rman just deletes the control files and does not remove the backup piece saying no obsolete backups found .

On disc i can see older backups .

What is the CONTROLFILE_RECORD_KEEP_TIME parameter set to?

And, by the way, next time you past code please enclose it within [code] tags as described here How to use [code] tags and make your code easier to read

Why do you have this:

CONFIGURE RETENTION POLICY TO RECOVERY WINDOW OF 60 DAYS;

Then do this

DELETE NOPROMPT OBSOLETE RECOVERY WINDOW OF 10 DAYS DEVICE TYPE DISK;

Offhand, I'm not seeing why those files haven't been deleted. Your case doesn't match what usually leads to the question of why "older" backups are still hanging around.

As an aside, I'd get rid of the hard-coding of all those environment variables. Instead of

ORACLE_SID=cfp106;export ORACLE_SID
ORACLE_HOME=/u01/app/oracle/product/11.2.0.4/db_1;export ORACLE_HOME
PATH=$ORACLE_HOME/bin:$PATH;export PATH
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH;export LD_LIBRARY_PATH

I do this

export ORACLE_SID=cfp106
ORAENV_ASK=NO
source oraenv

oraenv will take care of setting ORACLE_HOME, etc to the proper values. Setting ORAENV_ASK=NO before calling oraenv will cause it to use the current value of ORACLE_SID instead of prompting for it. By coding your scripts this way, you eliminate having to come back and change all those hard-coded values when you upgrade. One of my fundamental rules for writing code, any code, any language is "do not hard-code values that are possibly subject to change."

What does this mean? I asked about the CONTROLFILE_RECORD_KEEP_TIME, is that what you are describing? Because if you have not set it, you will get exactly the effect you describe: old backups not being deleted.

This is wrong. If you want to keep backups for sixty days, use KEEP UNTIL SYSDATE+60. And of course increase your CONTROLFILE_RECORD_KEEP_TIME accordingly.
