The Berkeley DB library uses the following environment
variables:
-
DB_HOME
-
If the environment variable DB_HOME is set, it
is used as part of File naming. Note: For the
DB_HOME variable to take effect, either the
DB_USE_ENVIRON or DB_USE_ENVIRON_ROOT flags must
be specified to DB_ENV->open().
-
TMPDIR, TEMP, TMP, TempFolder
-
The TMPDIR, TEMP, TMP, and TempFolder
environment variables are all checked as locations in
which to create temporary files. See DB_ENV->set_tmp_dir()
for more information.
