Hi Walt,

That looks all fine. However, you can do these changes from within in the IDV
itself.

To increase the amount of memory available to the IDV:
https://www.unidata.ucar.edu/software/idv/docs/userguide/misc/PerformanceTuning.html

The -d64 option look suspicious to me though I don't think it can hurt.

When downloading the IDV, make sure you get the right version (32 versus 64 
bit).

Best,

Unidata IDV Support

> FYI...
> 
> Kept getting heap error on starting IDV with a Win7 64bit OS. It would
> only start with -Xmx 1200m. Anything more caused heap error.
> 
> After loading Java 8 64 bit v112, I though that would solve problem. But,
> I had to add the -d64 flgt. That didn't work either until I found this

> 
> java -d64-Xmx2048m
> 
> When I tried what seemed obvious:
> 
> java -d64 Xmx2048m
> 
> That is... with an extra space, I got a heap error message.
> 
> Just edit the runIDV.bat to include the --d64 like this:

> java -d64-Xmx2048m ...

> Hope this solves others more frustration that necessary over the holiday
