[IDV #OWL-239023]: Starting java - Heap error SOLVED

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
> trick (bug?):
> 
> 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 ...
> 
> or whatever heap size you need.

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