Sadly, BEA also makes WebLogic, of which I was told today by a support engineer (after inquiring after some debugging): "We know it[WebLogic] has the capacity for logging, but we haven't found the directive to enable it yet." - anonymous to protect the victims. This from a group that's been working with WebLogic for 2-3 years. Gah! There are signs that a design is needlessly complex. This is one of them.

I had to play with Oracle's C network API to write some parts of a driver, and I think that there is a suprising amount of info that DBs make available, but aren't used very often.

You'd know more about RosettaNet than I. Received on Wed Mar 28 2001 - 16:18:48 CST
