The parameter STANDBY_ARCHIVE_DEST that you need to have on the init.ora file of the standby database (required in a managed mode) needs to be a valid path. (duh!)
(Wait, heres the real resolution...)
don't be confused by the convention of the value in that parameter (STANDBY_ARCHIVE_DEST) with those used in LOC_ARCHIVE_DEST_n. I'm refering to the prefix of "location=". The STANDBY_ARCHIVE_DEST parameter doesn't require the prefix and will not work if the prefix ("location=") is used.

This thread from 2 years ago seemd to have gone unresolved. If thw owner eventually found the answer on their own....IT WOULD BE REALLY NICE IF THEY COULD COME BACK TO THEIR ORIGINAL THREAD AND CLOSE IT OFF WITH A RESOLUTION.
I found all these threads related to issue...ALL OF THEM WITHOUT ANY RESOLUTION TO IT. I'm almost positive more 75% of those thread were eventually resolved the owner.
Well, I had the same problem this week and none of these threads helped me at all.
AND PLEASE, IF YOU FIND THE SOLUTION TO OWN THREAD, DO SHARE IT BY REPLYING TO YOUR OWN THREAD.
