I was planning to do the very first deployment from development to production in a new customer environment. Using the transfer out – feature of TM1 Performance Modeler it should have been straightforward but right after the transferring started I encountered an nasty error message:

Transfer has failed due to the following error(s):

ERROR

The transfer failed.
java.lang.OutOfMemoryError

OutOfMemoryError

What a nice way to start production deployment. Server had gigabytes of free memory but somehow insufficient amount of it was available to Performance Modeler. Google to rescue and I found the following IBM Support page: http://www-01.ibm.com/support/docview.wss?uid=swg21600719

I found out that there’s a yet another XML configuration file called ModelingMDT.ini that should be adjusted. It’s located in the following directory:

C\Users\<USERNAME>\AppData\Roaming\IBM\Cognos Performance Modeler\bins\bin_10.1.XXXX.X

I just increased the value -Xmx512M in to -Xmx1024M and voila’: transfer out succeeded this time. Our model is pretty small at the moment but still it doesn’t fit in the default 512MB while transferring the objects. I think it’s a pretty small value for a default one. What do you think?
