If the numbers are coming from the database, then the general technique is to increment the number first, then to read that number (in the same transaction). begin tran update number_fountain set num = num+1 select num from number_fountain commit Hope that helps Dan On Mon, 29 Oct 2018 at 18:25, Aída Betzabeth Dávila Sotelo < aida.dav...@vortech-it.com> wrote: > Hi! > > Is there something in apache isis that I could use or configure for > concurrency management? > > Currently I have a problem, I call a function that returns a consecutive > number, but if I call them at the same time twice, I get the same number as > a result. > > Can anyone tell me how to solve my problem? > > Thanks in Advance. > Aida Davila >
