: 5. What about the future of the products? CORBA? Is

: 6. Are the APIs object-oriented or rather low-level buffer/offset

: 7. How long does it take to have a proof of concept and the decision

: The API is pretty pathetic in a multithreaded environment like NT or

: your own locks to their client API's. Non threaded support also means
: that you can only
: realistically create one transaction from the client at a time.You could
: create more but it involves some serious
: programming undertaking. As for the server stuff it completely non
: rentrant and worse not event linked with the
: threaded C runtime libraries. In a nutshell no threaded support
: whatsoever.
 

: As far as administration and other TP features it is very good. If the
: above is not high on your requirment list, then Tuxedo is a good choice.
: They are supposed to be integrating their stuff with OTS. We'll see.
 

: Take a look at Encina. It completely solves the above problems. It
: already has OTS support.
 

: Good luck,
