SAP HANA consumes all space and make system slow.

Dear Experts,

I have sap hana details as below.

i started the database just 30 minute ago and then i took this scree-shot.

and its os free-g is as below. and os is suse.

But after 10 to 12 hours of the restart free space would be only 1 GB. this is what i realized and mh hana system will start behaving slowly and my s4 application users will face slowness issue.. So what could i do to solve this problem. I have googled a lot but still not geeting any clue. How can i keep my os memory free atleast 10 gb.

I am using hana 1.0 sp11 will be upgrading it soon as well.

Please suggest.

    Hi Prashant,

    I detect two different objectives that are not necessarily related:

    • end-user performance
    • keeping os memory free atleast 10 gb.

    What is most important?

    As a Google search typically returns the haystack (with some adds) and not the needle, you might find more interesting information about SAP HANA memory usage in the SAP Support knowledge base (KBA articles) and documentation.

    This will help you understand how SAP HANA manages memory.

    Should you face a performance issue, best to investigate what may cause this (there is a guide on that too). OS memory statistics are just a measures.
