Don't you find it weird how software get more and more human-like? These days even talking trash to one another.. <sigh>

12630, 00000, "Native service operation not supported" // *Cause: An operation requested by a user is not supported by the native

My guess is that you have the thin JDBC drivers wired for some option that Net8 on the back-end can not support. Or, this option is hardwired (but then this should have been in readme's hopefully).

I did a google on http://www.google.com/search?q=oracle+jdbc+broken-connection+function

It turned up quite a few pages. Hmm.. seems like this option that fails is akin to an IP OOB at OraNet level to deal with a CTRL-BREAK from the client. You may make more sense out of that google set than I..
