Hello everybody.

I am kind of confused with the output of *"crosscheck archive log all"* and not able to understand clearly. Can somebody please help me understand the output of following two commands.

LIST ARCHIVELOG ALL;
CROSSCHECK ARCHIVELOG ALL;

Is it that "LIST ARCHIVELOG ALL" displays the list of archivelogs that have been backed up by RMAN? and "CROSSCHECK ARCHIVELOG ALL" cross checks those backups taken are available in backup set on disk location or not?

But if this "LIST ARCHIVELOG ALL" displays the list of archivelogs that have been backed up by RMAN then "LIST BACKUP SUMMARY" should show "A" for archivelog in LV column but it doesn't show "A"

Any help would be greatly appreciated..

Thanks
