  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:

1. What is the development time-to-product/market? How long is the training process for developers?
2. What is the cost/staffing requirements in administration?
3. How complicated or error-proness of either of the APIs? Tricks and traps?
4. Is there any performance problem with the two-phase commit with a

     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,
