After reading through the referenced document, I have this question. How do I determine the predominant message size? What tools and techniques?  

I have a GIS application with a large number of blobs, so I think there are probably a fair number of large messages.

YES!!! [29-JAN-2009 10:55:52:757] nsopen: lcl[0]=0xf4ffefff, lcl[1]=0x102000, gbl[0]=0xfabf, gbl[1]=0x0, tdu=32767, sdu=8192

That placement in the tnsnames.ora is indeed the key. And now that you've shown me, I've found an example of it in the docs as well:

Thanks, Tim!!!
