ACUFH Configuration File Variables for DB2

Restriction: This topic applies only when a Database Connectors license has been installed via the Micro Focus License Management System.

Before running Database Connectors, you must set the A_CONFIG environment variable to the name of the ACUFH configuration file. You may want to make and use a personalized copy of the ACUFH configuration file to avoid impacting other users. Set the A_CONFIG environment variable to identify your own personal copy. For example:


SET A_CONFIG=directory-name\my-file-name


export A_CONFIG

ensures the specified configuration file is used when interfacing with your database.

This section lists the ACUFH configuration file variables that are specific to DB2. For ACUFH configuration file variables that are generally applicable to any RDBMS with which Database Connectors communicates, see ACUFH Configuration Variables in the Run Time Configuration section.
