About File Handler Configuration

Instead of the COBOL file handler picking up its configuration from a fixed location for all regions on any given machine, Enterprise Server for .NET allows COBOL file handler configuration to be defined on a per-region basis via the region start-up file. The benefits for doing this are:
  1. If Enterprise Server for .NET is scaled out across multiple machines, it eliminates the possibility of the COBOL file handler being configured differently on each machine if the same extfh.cfg file is not used. This ensures consistent application behavior from machine to machine.
  2. It is very likely that different Enterprise Server for .NET regions will require different COBOL file handler configuration according to the applications that are being run.
