Hello Everyone,
My company is considering using some TP monitor system for
transaction
processing. In particular we are interested in Tuxedo, Encina, etc..
I wonder if some one with working experience can kindly provide with
me some advice/lessons on this issue. Below is a list of questions that I put together, without much in-depth knowledge of either products:
RDBMS backend? Can I do 50, 100/sec inserts and updates to two or three
databases at the same time?
5. What about the future of the products? CORBA? Is Orcle/Sybase/Micrsoft
doing anything in this area?
6. Are the APIs object-oriented or rather low-level buffer/offset counting
stuff? How can I incorporate that into an distributed OO app framework?
7. How long does it take to have a proof of concept and the decision
making procedure?
Again, thanks very much for your help. Your suggestions and advice
are
highly, highly appreciated.

The API is pretty pathetic in a multithreaded environment like NT or
OS/2. You must provide
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,
