The user's account should have been set up correctly to access the Oracle RDBMS system. This includes environment variables such as ORACLE_HOME and ORACLE_SID. See your Oracle documentation for more details.
In addition to the variables required for Oracle, you will need to do the following:
Ensure that your execution path contains the name of the directory where you placed your newly linked Acu4GL runtime executable.
If you are not using the automatic login procedure, you will need to set the ORA-LOGIN and ORA-PASSWD variables, either in your environment or in the ACUCOBOL-GT runtime configuration file. For security reasons, it is best to set the password variable from your COBOL program by asking the user to enter a password and then executing:
SET ENVIRONMENT ORA-PASSWD TO user-entry
You may want to make and use a personalized copy of the configuration file to avoid impacting other users. The compiler User's Guide describes how to use the A_CONFIG environment variable, or the -c runtime option, to identify a personal configuration file.
If you will be accessing files that you do not personally own and that do not have public synonyms, you will need to set the configuration variable USER-PATH.
For detailed information on ORA-LOGIN, ORA-PASSWD and USER-PATH, see section C.3 "Configuration File Variables" in this appendix.
