Connection file parameters
A connection file allows you to configure a set of connection parameters. The following table lists the connection parameters that can be set for each connection type.

Note: The combined length of the Client ID, Default password, and other connection file parameters listed in the table above must not exceed 30,000 non-Unicode characters when connecting to an AppServer.
Parameter values are fixed when the beginSession procedure is called. When the beginSession procedure is called, the following process takes place for each parameter to determine its value:
1. If the parameter value was set by a call to the corresponding set<parameter>routine, the values set in the call is used. If the same set<parameter>routine is called more than once, the last setting is used.
2. If the parameter value was not set by a set<parameter>routine, and a parameter file is specified, and the parameter is set in the connection file, then the value in the connection file is used.
3. If the parameter is not set by a set<parameter>routine, and it is not set in a specified connection file, then the default value is used.
The following figure depicts the process for determining the parameter value for each parameter during execution of the beginSession procedure .

All connection parameters must be set prior to calling beginSession.
