Linux cache
Hi,
We are working on OEL5.7 (Oracle Linux) OS. We have a server with 64GB RAM. When we issue free -m command which shows the used, available and cached space. Most of the space is shown in cached section, where as we are not really doing much activity on the server.
It's like cached is somewhere around 23GB, how can we see what is in it which is cached and how do we clear it?
Thanks and Regards!
