AWR/ADDM Reports are not available all of sudden..
We have noticed that AWR/ADDM reports not available all of sudden in one of the instances of 4 node RAC Instance and I do not have clue as what caused it. As far as I know, we have not made any changes to the database.
Would you please let me know as how to figure out this problem.
Thank you for your help in advance.
