To configure the client environment for Database Connectors, you usually use an ACUFH configuration file.
The minimum settings required would be the ORA_LOGIN, ORA_PASSWD, and A_ORA_DATABASE variables; refer to ACUFH Configuration File Variables for additional variables you can include. If you are accessing files that you do not personally own and that do not have public synonyms, you may also need to set USER_PATH.
You use the A_CONFIG environment variable to identify the ACUFH configuration file, which allows you to create your own personalized copy of the file, to avoid impacting other users.
If you are concerned about including passwords in a configuration file, you can set these details in your COBOL program or environment. The following syntax is an example of how you can set a variable within your code:
SET ENVIRONMENT ORA_PASSWD TO user-entry
