delete VERY old archivelog

Jun 7, 2017 9:41PM

I just start to taking care of a database that has been around for a long time ( 10.2.0.4).

I just found out that there are lots of old archivelog inside ASM DISKGROUP. From 2009 all the way to 2015.

ASMCMD> ls

2009_06_02/

2009_06_03/

2009_06_04/

2009_06_05/

until...

2015_01_13/

2015_01_14/

2015_01_15/

2015_01_16/

2015_01_17/

and there is none until very recently. this is of course due to backup + archivelog delete input.

2017_05_16/

2017_05_17/

2017_05_18/

2017_05_19/

2017_05_20/

when i list all archivelog via RMAN, this is what I get.
