I know there were some posts about this a few years ago but I was wondering if anyone has any tricks to get Model Manager to run 64 bit or atleast with more memory. I have increased java memory (-Xmx) to the max of 1024m but I still get hangups when working with some large assemblies that we have. One assembly that I am working with now I can get to load if I set some sub-assemblies to load as partial however I cannot consistently get the top level assembly to save which I need to do when I create configs owned by the top level. The assembly has 150,000 child objects. Thank for your help.
