- Someone called me to task, via email, on my response to the question
- about Tuxedo and OnLine, where I stated that TP/XA was required for
- 2 phase commit. Let me clarify that OnLine 5.0 has 2PC for homogeneous
- OnLine transactions, i.e. if you are using a regular front end (DBaccess,
- ESQL, 4GL, etc) you can do a 2PC in an OnLIne/I-Star environment.
-
- When you start using Tuxedo, regardless of what client product you use
- (4GL does have a library that supports Tuxedo calls: 4GL TP Toolkit),
- you then need to add TP/XA in order to get 2PC *via Tuxedo*. OnLine,
- by iteself (i.e. w/o TP/XA) will not support a *Tuxedo* global (i.e.
- distributed) transaction.
- You *CAN* use Tuxedo and OnLine w/o TP/XA if your transaction does not
- need to be a Tuxedo global transaction across multiple RMs.
-
- This should either clarify the situation, or hopelessly confuse it!
