This is part two of this series on Revit Journal files. Last time, in Part 1, I showed where the build information is stored in the file. In this part, We will look at the hardware information that is stored in the file.
A little ways down from the Build number in a journal file is all sorts of information about your computer. This includes the version of Windows you are using, service pack installed, processor information, video controller (card) information, and information regarding each printer you have setup on the machine.
Each section has valuable information that helps product support understand your problems a little bit better. One of the most valuable items in under the Operating System Information heading.
While this section provides us your operating system name (under Caption) and Service Pack (Under CSDVersion), the one that interests product support the most is MaxProcessMemorySize. This is the journal file's way of capturing the amount of memory that is available for Revit to use. On a 64 bit machine, this number can be extremely high, on my 32 bit machine this is 2 GB. You can bump this number up on a 32 bit machine by using the 3GB Switch.
Support needs this information to help to understand if there is a possibility that you are having memory related problems. This is one of the first places we look.
Next time, I will talk about how a journal file helps to show us memory usage within a session of Revit.
