Configures the database environment's intermediate directory permissions.

The syntax of this parameter in the DB_CONFIG file is a single line with the string set_intermediate_dir_mode, one or more whitespace characters, and the directory permissions.

Directory permissions are interpreted as a string of nine characters, using the character set r (read), w (write), x (execute or search), and - (none). The first character is the read permissions for the directory owner (set to either r or -). The second character is the write permissions for the directory owner (set to either w or -). The third character is the execute permissions for the directory owner (set to either x or -).

Similarly, the second set of three characters are the read, write and execute/search permissions for the directory group, and the third set of three characters are the read, write and execute/search permissions for all others. For example, the string rwx------ would configure read, write and execute/search access for the owner only. The string rwxrwx--- would configure read, write and execute/search access for both the owner and the group. The string rwxr----- would configure read, write and execute/search access for the directory owner and read-only access for the directory group.
