Re: Tuxedo?

Zeqing Xia wrote: 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.

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, Tarek Hammoud
