Tim,
I plan to beat on this over the next few days. However, here are two
small changes which I've found to be necessary when working with a DB2
backend database. Since making these mods all ugly messages are a thing
of the past.
In my opinion, it's time to throw in the towel and report the true
'Active' status back to the proxy client with every call. I'm getting
hammered at work, but will attempt to code this up "Real Soon Now" <g>.
