Add unlimited external SQL connections to your 4D Server-based application

The 4D SQL Expansion allows unlimited incoming SQL connections to your 4D Server application.


Without this expansion, each SQL connection would typically use up a concurrent Client connection (i.e. a 4D Client license). For intensive use, you can bypass this limit with the 4D SQL Expansion, which allows unlimited incoming connections, reserving your Client licenses for native 4D connections.


4D SQL Expansion license pricing is on a per-processor basis. One license allows the use of two CPUs.


For example, if your server has 4 processors, you must use 2 licenses, irrespective of the number of cores within each processor.



NOTE: The 4D SQL Expansion license can only be used with 4D Server applications.
