To really impress potential buyers of Dynamics AX, it is important that we are capable to show that AX 2012 responds fast. We normally use the Contoso hyper-v demo environment, and our laptops have limited resources. Starting a demo on a cold system, we often see that forms takes some time to operate in optimal performance. If you already have opened a form, it is much faster the second time you open it.

So how can we give the users a view of a fast system without manually opening all the forms prior to the demo?

We can warm them up J. I use the following job-script to open and close all the forms I’m planning to use. I just traverse through the AOT, and open the form, and then I close them again.

static void WarmupRF(Args _args)
{
    //This code is for "warming" up all RF* forms and code I have in the VAR-layer
    UtilElements e;
    TreeNode treeNode;
    FormRun formRun;
    Args args = new Args();

    while select e
        where e.utilLevel  == UtilEntryLevel::var    //<-- spesify layer here
        &&    e.recordType == UtilElementType::Form  //<-- and only forms
        &&    e.name like "RF*"                      //<-- I only want the forms that starts with the prefix RF*
        {
            try
            {
                treeNode = xUtilElements::getNodeInTree(xUtilElements::parentElement(e));
                args.name(treeNode.AOTname());
                formRun = ClassFactory.formRunClass(args);
                formRun.init();
                //formRun.run();   //<-- No need to run the form, but sometimes it can load the data
                formRun.close();
            }
            catch
            {
                Infolog.clear();
                continue;
            }
        }
}

The code must be modified to suit what you want to “warm-up”, but you get the idea.

This will make you demo go much more smooth, and you truly show the potential and performance of a warm Dynamics AX system.

Happy DAX’ing
