Infrastructure Software

Hi all,

We are having RHEL 5.8 server.It is the db tier of our test oracle application R12.1.3 .
For the past 20 days it always using the full RAM memory.Before 2 weeks the server has 4 GB ram and we thought that we may have insufficient memory.So we increased the RAM size by 6 GB.Now the total RAM memory is 10G. But again the server started to use the full RAM memory..

output of free -m

total used free shared buffers cached
Mem: 9991 9935 56 0 27 8323
-/+ buffers/cache: 1584 8407
Swap: 7967 106 7861


and the output of the top command is (Result sorted by memory usage)
