dead.letter in my RMAN backuppiece

[TX-DBA]

#####Background
1) CRONJOB runs 2 RMAN shell scripts at 3AM

backup_begin.sh- export and rman backups
report_begin.sh- list rman reports


My report_begin.sh script, which was messed up, was sending/writing
the dead.letter info to the RMAN backupset peices, thats correct! It
was over-writting them and giving a new file timestamp which was newer
than the directory time stamp?? I was shocked when I did a cat command
on a old RMAN backup piece and saw my dead.letter email. The
non-cronjob RMAN files (82,83) I ran manually are not effected.

It also corrupted some data files too.

Errors in file /u01/app/oracle/admin/NEPTUNE/bdump/neptune_smon_21 214.trc:
ORA-01565: error in identifying file
'/u02/oradata/NEPTUNE/undotbs01.dbf'
ORA-27046: file size is not a multiple of logical block size
Additional information: 1


Hense a restore/recovery on 2 day old backups.

I fixed the email portion of the script and its working and things are
fine, but how could this happen?

Guess:
1) Both RMAN scripts are run at the same time?
2) I found a secret email feature.
3) Some global variable in both shells got mixed up.
