From reading other posts on this matter about UV/UD scaling, I expect that as far as the PRDBMS and hardware, the sky is the limit. And with Claus Derlien's comment about 30000 users at France Telecom, the sky is pretty high up there.
But I wonder about the applications. I know that the LIS that I was supporting until recently used a single place to get a transaction number. Now when you have 100 users, locking/reading/writing that single record was not a big deal. But if you had 1000 users? I think that you would start having problems.
So I suspect that the scaling problems are not at the UV/UD and hardware layers but within the applications. Control Record locking. The transaction Number generation that I referred to earlier. Things like that.
I believe that as the user counts got bigger, the application would have to be checked on to see where it would need to be modified to match the greater number of users than was imagined when the application was written.

At what point in the life of application software would it be so large that you could not (or would not want to) support it with your existing UniData or UniVerse database?
Is there a point where you would be better served by DB2 or Oracle, for example due to the scale you are working with?
I hear people talk about moving way from U2 in order to do ODBC and use standard industry tools (and most find that the grass is not greener for those purposes), but I don't hear about switching because of running into scaling issues. However, we sometimes think of PICK as addressing small-to-mid size businesses and RDBMS folks sometimes think of their products as scaling the best.
So, what's the cut-off for U2? Thanks. --dawn
