RE: [U2] UniObjects for .NET - Reference / Experience / Advice
Ray I have used UO.NET for WinForms development and found it to be fast and stable : just as its predecessor (UniObjects) has always been. I used UniObject (uvObjects) since it first came out for all kinds of heavy data applications - from 4GLs to reporting tools - and have never been disappointed in it. It just works - that's always good to say! And for transactional work it is quite simply the quickest route available. But UO was designed for permanent, stateful connections: previously I and other members of this list have written connection pools for stateless environments where needed, before IBM added their own connection pooling facility (and with it, the restriction not to use third party connection pools as part of the product licencing). The problem is that the UO native connection pooling required to run in a stateless and multithreaded environment such as a service or ASP.NET middleware is very new - connection pool licencing is a new feature in UniVerse 10.2 - and so I doubt you will find that anyone has had a chance to really prove that part of it yet.

Brian Leach stated connection pool licensing is a new feature in UniVerse 10.2 - and so I doubt you will find that anyone has had a chance to really prove that part of it yet. The connection pooling portion of UO.NET has be extremely tested for one U2 Channel Partner (what we used to call VARs) that has approximately 500 end user sites that are up to over 1,000 users at some locations. This particular Partner rewrote their whole front end using UO.NET and the Microsoft development environment for their front end. Back end and processing remains in UniBasic. The UniObjects layer is the same code for both the UO.NET and UOJ (UniObjects for Java). It is so blazing fast that some Partners have written new front end report writers with a GUI look and feel. Some Partners have written the middle layer with the intent of using multiple databases for updating - like updating a U2 Database in addition to writing to an SQL database for Reporting Cubes. Super highly scalable. Extremely fast. Steve Stephen M.

RE: [U2] UniObjects for .NET - Reference / Experience / Advice
Just a question. I'm wondering what the IBM UO.Net pooling provides over using MS Enterprise Services pooling with UO.Net? The MS pooling component is built into the Windows OS (Enterprise Services for .Net aka Component Services). The IBM option seems to be expensive as far as licencing goes especially in light that seemingly similar functionality is already available. Can anyone tell me or are there any whitepapers or manuals available on IBM U2 pooling that might describe any benefits it might have that would justify the extra cost?

Once you see Connection Pooling in action with UO.NET, you wouldn't want to go back! IBM has some examples applications you can download from their website in VB.NET and C#, using connection pooling. Unfortunately, there is a separate license and cost associated with it. But it is worth it, for those that need it. You only need to buy the licenses you require. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Stephen O'Neal Sent: Wednesday, 29 November 2006 1:42 AM To: u2-users@listserver.u2ug.org Subject: RE: [U2] UniObjects for .NET - Reference / Experience / Advice Brian Leach stated connection pool licensing is a new feature in UniVerse 10.2 - and so I doubt you will find that anyone has had a chance to really prove that part of it yet.

RE: [U2] UniObjects for .NET - Reference / Experience / Advice
Hi David, Are there any whitepapers or info about it. I'm assuming now that there is some U2 server-side componentry that might make it faster or have more functionality than pooling thru Ent Services. I'd be interested to compare. We are using Ent Services for our procurement web service and are finding performance is good and reliable. Haven't had to touch it in 2 years and it has handled everything thrown at it with aplomb (and it has been hammered) so I can't see a reason to change and pay for pooling right now. However, if there was significant functionality in the IBM product not in ES it could be worth investigating.
