Memory parameter.

Hello everybody,

I installed the ECC 5.0 with windows 2003 (64-bit) + SQL server 2005 with 32 GB memory.

Database size is 350 GB ( migrate from 32-bit to 64-bit).

Now, I want to configure the memory parameter for performance view.

Please suggest me memory parameter and how to calculate their values?

which parameter will effect on performance?

Also suggest PHYS_MEMSIZE value...

Thanks

Ganesh

    Hi Ganesh,

    This is really a big and subjective topic, you need to understand the concept and read a lot. Try to browse help.sap.com and sap notes as well.

    For e.g. consider these links and their subtree pages -

    https://help.sap.com/saphelp_nw04s/helpdata/en/d1/80b716dc8111d2ac8f0000e83539c3/content.htm

    https://help.sap.com/saphelp_nw04s/helpdata/en/02/96268c538111d1891b0000e8322f96/content.htm

    PHYS_MEMSIZE is the total RAM assigned to a particular SAP system. Whenever if you need to add some more RAM to particular SAP SID then PHYS_MEMSIZE is the parameter you need to update. Just by adding more RAM to the physical host will not reflect into SAP if we don't update this parameter.

    Thanks

    Hi ganesh

    PHYS_MEMSIZE parameter values are in MB if you give more then you physical memory it will throw the error message. Better you can check the SAP note 88416 ZERO Memory Administration its very important to set the values in windows base servers

    Regards
