The problem am having with memory allocations is,ii have 32gb RAM and 16GB assigned to SGA using AMM,but OEM12c complains the memory utilization is 95%.Top command doesn't show any processes that takes full memory.Is there any command which gives os level process which consumes memory taking processes.
free memory is 130M out of 7985M, but only 504M is used by running processes. There is 7480M available on demand.
