SolMan 7.0 + IDES ERP 6.0 on 1 machine for 1-man-show with MaxDB?

Sorry - I know that what I've done is unusual and somewhat suspect, but anyway: I've successfully installed -just for personal interest- both (SolMan 7.0 plus IDES ERP 6.0 SR3) on 1 machine, which is a very small PC with Windows Server 2003 x64 and MaxDB. I can start SolMan OR I can start ERP. But every time the used memory climbs up to about 10 to 12 MB.

If I would start both in parallel (but I hav'nt done that yet because I had not the courage to find it out), real + virtual memory might not be sufficient (and the mainboard of the pc does not allow more than 4 MB of memory).

Has everyone ever tried to downsize the default parameters of sapinst to the lowest possible values for a 1-man-show? I wunder what the minimum values for all the parameters of such a SolMan + ERP on MaxDB configuration might be, that would perfectly work if there would be only 1 user?

Is there any help or interest in this? If I could not receive helpful answers, it might be possible to me to provide the results of my furthers studies. But I would really prefere to make use of other collegues' experiences first. Thank you for your answer.

    Hi there,

    first of all - you're talking about Gigabytes instead of Megabytes are you?

    Thought so... Anyhow, it doesn't matter how much RAM you can put into the machine, since Windows supports virtual memory, a.k.a. a pagefile.

    So basically it's not a question if the whole thing would run, but rather a performance question.

    The next thing is: you didn't try it. Why not? What bad thing should happen?

    Move on - try it out.

    MaxDB will start as well with a very small data cache.

    NetWeaver will start with only a few disp+work processes and perhaps you don't need a J2EE instance.

    Depending on what you want to do, you can save a lot resources.

    regards,

    Lars

    • Dear Heiner,

      as far as I can remember there was a kind of "trick" to have multiple pagefiles per partition by putting them into folders - I would have to google that right now, so that's your turn 😉

      Anyhow, you won't damage your installation by lowering the e.g. DATA_CACHE size of the MaxDB instances.

      The database will just have to perform more I/O then.

      Concerning multiple products in one MaxDB instance - that's possible via MCOD, but not like MSSQL Server does it right now.

      Anyhow, the overhead per instance is usually not an issue, if you configure them correctly.

      best regards,

      Lars
