Database Software

Hi All,

We have oracle database 11gr2 RAC @primary and 11gr2 standalone @DR site with oracle dataguard configured between them.

Archive log disk on both sites were 99% full hence I decided to clear few old archive logs from both the sites. For which I followed below steps;

#crosscheck archivelog all;
# delete archivelog untill time 'SYSDATE-10';
#delete expired archivelog all;


I guess this command should have deleted all archive logs prior to 10 days and all expired archive logs. But It did not!! ...... when I login to asm and browse the archive disk group archivelog directory I still see archive logs as old as 8 months :(.. also it did not clear considerable disk space ...

Also during the cross check I noticed that rman crosscheck starts from date just 30 days ago till today.. It is not cross chcking logs which are 30 days old or more..

I wanted to know why rman did not clear old archive logs?? and how can I clear them safely from both primary and physical standby database.

Thanks..
