MDIS Performance

Hi all

we are having some issues with the MDIS performance. Can anyone tell me what the optimal ini setting should be? We are processing 1 idoc every 10-12 seconds, but need to process 1 idoc every 2-3 seconds.

So far we have set MDIS parameters "Interval = 2" and "Chunk Size" = 50,000"

We are running MDM5.5 SP04,on SQL Server, Windows Platform. MDIS and MDS, MDSS are running on seperate boxes -with8G RAM.

All help appreciated.

    Hey ccr,

    the poor import performance can have several reasons. What kind of structure is your import source file? Are there several iDocs in one XML file - like many MATMAS iDocs per file for material import? Try to do this to increase performance.

    Also: what do you import from the iDocs? If you want to import data from different segments and you access these data using virtual extendedd lookup tables in MDS import mapping, try not to. We made the experience that it is much faster to import each segment on its own, keeping the import mapping as simple (flat) as possible. No lookups. This pushed our performance by factor 40!

    Also: try to find out what's the bottleneck: is there enough memory? How abou the machine's CPU? If the system's resources are used by close to 100%, getting a bigger machine might be a solution.

    What does your system landscape look like? DB server, MDM and ImportServer on the same machine is not an ideal scenario...

    Hope this helps 😊

    Good luck and best regards,

    • UPgrading to SP05 should bring an additional advantage. Import Loads perform much better there with new features like File aggregation.

      In addition you should make sure (I guess that's already the case) , that MDS and MDIS are in the same subnet.

    one question: do you send IDOCs one by one to MDIS or as a bundle of IDOCs?

    if you send one by one there is a nice way to send

    then in a package described by Stefan Grube:


    this way you can save MDIS performance lost on importing many small files

    and import one bigger instead

    to test this you only need to create XML port in WE21 and access to SAP folders

    (to get the generated XML file) so pretty easy to evaluate if this will help you or not
