Database Software

Hello all ,

I try out different recovery scenarios on DR environment (without harm). Its just a test activity to equip myself.

I met some issues (archive logs are more and it consumes more disk space)

At least 10 times i opened database with resetlogs option. (Several times incarnation changed)

now i am trying to delete all archive logs , but database could not identified expired archive logs

through rman how can i delete all expired archivelogs ?

list expired archivelog all;
delete expired archivelog all;
crosscheck archivelog all;                 

db : 11g on linux
