Hello Tushar,

Where are you seeing your Physical Memory ? if you are referring to ST06 or OS Level Free command they show the same vale under "Free" , it doesnt mean that you have memory crunch .

In Linux Operating system system will not release memory immediately this is stored under "Cached".

You can see the same below.

You should start worrying only if your cached is decreasing and users are going to Memory Dumps .

Then you should re-evaluate your resources and based on user Load you should consider upgrading your Hardware.

Dear Tushar,

Hope you are doing good.

For this particular reason, SAP has developed the Quick Sizer (which is a Web-based tool).

This is available free of cost for customers from:

http://service.sap.com/quicksizer

and

http://service.sap.com/sizing

You will be able to identify whether more hardware/ server nodes etc. are needed and resize the server accordingly. With the Quick Sizer you can translate business requirements into technical requirements.

Simply fill in the online questionnaire, an up-to-date survey that is based on business-oriented figures. The results you obtain can help you select an economically balanced system that matches your

company's business goals.

Hope this helps.
