Hi I don't have 250 instances of the same module. I have 250 different modules with 1or 2 instances . In fact I have aout 30 different modules, but multiplexed on different configuration files, and each confiuration file pointing on a different database. Let's say I have  30 different modules running on  25 different databases. Miguel Arroz a écrit : Hi!

If you don't mind asking, why in the world do you want to run 333 instances on a single server? That seems like a tremendous waste of resources... in normal WO setups, each server runs just a few instances (a few being like 10 or so at max). You're wasting RAM like crazy, forcing the OS to handle a huge amount of concurrent processes and threads, wasting a huge load of file descriptors on sockets between the adaptor and the instances, and between the instances and the DB... I would say you would use your hardware much better if you cut the number of instances by a factor of 100 or more.
