Hello MDM Gurus,
Is there any parameter which decides the MDM memory as we have in other SAP instances.
In my landscape I have 128GB of physical memory on Windows 2003 server.
I have 9 repositories hosted on this and when I check the process, MDS.exe uses around 10% of the memory.
As normal SAP instances, can we define a memory setting for MDM

Hi Mahesh,
1. Which version of MDM that you are using?
2. Are you planning to dedicate the entire host to MDM system or is there going to be anyother system which will share this host?
refer to link sizing guide and http://help.sap.com/saphelp_mdm550/helpdata/en/42/fc006b8adf1a61e10000000a422035/content.htm
1. Parameter CPU Count will restrict the number of CPUs that you allocate for the MDM system.
Parameter Reserved Memory Megabytes (windows NT/2000) will reserve the minimum
memory required for allocation.
2. However, below parameters influence the memory consumption
Max Initial MB to Retain
Import slice min, max,
Number of Rows Per Fetch

Hi Mahesh,
You need to set your memory settings(or other hardware settings) as per the MDM sizing guide provided by SAP. you can search this guide on google easily for SAP MDM 7.1 ans do the memory settings as per Sizing Document. Please let me know if you have further doubts.

Hello Ankush,
Thanks for your reply.
But my doubt is, as in SAP ABAP and JAVA there are memory parameters which define the SAP instance.
I have a MDM system which is on 128GB RAM ,Windows 2003 OS.
As per sizing guide we can get the information about the size through SAPS and based on this we can define our server.
But for MDS.exe MDM process, is there any static memory assigned to this ?
Thanks & Regards,
Mahesh Babu
Hi Mahesh,
As per my knowledge, there won't be static memory allocation provision for this. Since an applications memory usage depends upon the various processes it handles, so memory allocation would be dynamic depending upon the number and complexity of operations to be done. Hope this helps.
Thanks and Regards,
