Where is the DB_CONFIG file of Berkeley database located in Unix?

i'm new to Berkeley db, i have installed the version "db-4.8.30.NC.tar.gz" but now i would like to find the configuration information by using the configuration file.

I've read in the documentations that this file is named DB_CONFIG and it exists in the database home directory.

In my system, i have uzipped the tar file under /usr/db-4.8.30.NC but i still haven't found the DB_CONFIG file.

Well, i'm trying to find where the DB_CONFIG file is located in Unix, but i can't find it.

May you please help me?

Thanks, in advance

You (or a system administrator) writes the DB_CONFIG file by hand to modify any of the DB_ENV environment variables that can be over-ridden at runtime.

The DB_CONFIG file is stored in the db_home directory; the docs/programmer_reference/env_naming.html file has full details, but you can either pass an explicit db_home parameter in the DB_ENV->open() call or rely on the DB_HOME environment variable to locate the DB_CONFIG file, if any exists. The environment variable approach might be nice if the system administrator would reasonably want to move the storage around as they wish; the specific path name approach might be nice if you don't want to bother your system administrators with details of managing your storage.
