Grid Control auto-refresh customizations

Hey all,

Using GC 10.2.0.3.0, has anyone customized the webpages? Specifically, I'm looking to reduce the refresh time on the "Top Activity" from 15 seconds to 30 and 60 for use over VPN. DB Control 10gR1 had 30 or 60 seconds (I forget), which worked well for me, but not in GC 10gR2.

I've scanned the files in the OMS, but not being much of a Java-type, and having managed a custom UltraSearch implementation before, I'm leery about changing any files. Also, I've been unable to find exactly where this value would be located, unless it's buried in a binary somewhere.

Anyone?

TIA!
Rich
