Thanks Jonathan but while I do have a potentially larger PGA we seem to be using about as much as before. I am now pretty convinced that 11.1.0.7 is just "not dividing" the ( bytes processed from v$pgastat ) by 1024*1024 for the AWR report but 11.2.0.3 has this calculation fixed and is calculating MB correctly. My last 11.1 system is migrated but I was getting numbers in there that were huge. Can some other people do some double checking please? Thanks John -- //www.freelists.org/webpage/oracle-l
