Oops! You are right, Bruce. Thanks.
Now, I think I know why:
2004-10-09 06:23 redo log file 1_1439.dbf closed and archived
2004-10-09 16:12 <---- here is the later 'sysdate-2'( say, SCN XYZ)
2004-10-10 only a few activities
2004-10-11 00:42 redo log file 1_1440.dbf closed and archived
2004-10-11 15:39 redo log file 1_1441.dbf closed and archived
2004-10-11 16:12 I told RMAN to backup archivelog until time 'sysdate-2' delete
input
RMAN did backup and delete upto SCN XYZ, which was in 1_1440.dbf.
That's why 1_1440.dbf was deleted, even it was closed in 2004-10-11,
same day I ran RMAN backup/delete archivelog.

Roger,
Try using MI as the minute format rather than MM (which is 2 digit month)
HTH,

'sysdate -2' is different from what I thought it was! Thanks, Brian.

I used select to_char(sysdate-2,'DD-MON-YY:HH.MM.SS') from dual; when
it was run to make sure it was the time range I expected.

Hi list,
It was "Mon Oct 11 16:12:07 CDT 2004" and I ran the following
RMAN> run {
2> backup
3> format '/oback/obckp/redo-logs/DV2_%s_%p.logs'
4> archivelog until time 'sysdate-2' delete input;
5> }
Since I specified "sysdate-2", I expected it only archive/delete up to "Oct
09 16:12:06".
Was I right? But the truth is it archived/deleted redo file "1_1440.dbf",
which was created
between "Mon Oct 11 00:12:40 2004" and "Mon Oct 11 00:42:39 2004". WHY?
My last three redo files was:
