I totally get it when standalone but for RAC? If i have a FRA of say 50g, and 2 node RAC, since that parm must be set to same for all instances, does it make sense to say set it to 20G? is that the limit per instance or at database level? I'm trying to figure out if the numbers added up per instance? So say I want to be alerted at 80%, would i set it to 40G or 20G? thanks, joe _______________________________________ Joe Testa, Oracle Certified Professional Senior Engineering & Administration Lead (Work) 614-677-1668 (Cell) 614-312-6715
