The Server Configuration File
Configuration settings for the Integration Server are stored in the server configuration file (server.cnf). This file resides in the Integration Server_directory \instances\instance_name\config directory and contains parameters that determine how the server operates.
Typically, you will use the Integration Server Administrator to set parameters in the server.cnf file, but there may be times when you need to edit the file directly with a text editor.
For a list of parameters in the server.cnf file and their default values, see Server Configuration Parameters.
