Can we afford saying "Oracle 8i is > not supported in XA mode"? I don't know... saying it isn't supported might be better than all the problems people are having. Do you think it is ok to get a new Connection from the XAConnection whenever associateConnection is called? If we can do this, it wouldn't be too hard to change. I'm still mystified as to how Oracle can tell how many Connection handles we are using and how it can decide to object. thanks david jencks > > > I think there may still be issues in what xa flags we send in the > start/end > > calls, but I haven't had time to make a complete analysis. > > > > Thanks! > > > > david jencks > > > > On 2002.09.27 11:05:57 -0400 Igor Fedorenko wrote: > > > >>Thank you, David. > >> > >>JBossTX still has problems with oracle (see for example #614116 I've > >>been working on recently) and I was thinking if it worth fixing or we > >>can switch to Tyrex.
