Release 3.1: DB_ENV->open, DB_ENV->remove
In the Berkeley DB 3.1 release, the config argument to the DB_ENV->open, DB_ENV->remove methods has been removed, replaced by additional methods on the DB_ENV handle. If your application calls DB_ENV->open or DB_ENV->remove with a NULL config argument, find those functions and remove the config argument from the call. If your application has non-NULL config argument, the strings values in that argument are replaced with calls to DB_ENV methods as follows:
| Previous config string | Berkeley DB 3.1 version method |
|---|---|
| DB_DATA_DIR | DB_ENV->set_data_dir |
| DB_LOG_DIR | DB_ENV->set_lg_dir |
| DB_TMP_DIR | DB_ENV->set_tmp_dir |
