Enabling End-User performance monitoring using the Oracle application stack and Grid Control, depends on a script called oracle_smp_chronos.js however the the copy we've got will only work with MSIE (its hard-wired to the Microsoft browser event model). I had a look around forums.oracle.com to see if anyone had a solution - and I couldn't find anyone with the same problem. I couldn't - so I thought great, they've fixed it! But I can't find the fix.
But what's even more interesting is that Oracle no longer seem to be using their own tools for monitoring - a 'view source' on most of the oracle.com pages shows they are now using Omniture's SiteCatalyst.
