I have been using Redhat AS 4 Upd 6. And An application working on the this server and database Oracle.
This server have 12 gb memory. But Application using very low memory but memory cache very big. I am attaching a screen shot as top command export. You can see ram usage.
What are you thinking? Why I see ram using very big?
Also, How can i clean chace memory size? Is this chache clean can be reason any problem on the Application or Oracle Database?
