The RDMS$BIND_WORK_FILE logical name is used to redirect the
    location of temporary files that Oracle Rdb sometimes creates for
    use in matching operations. Oracle Rdb creates the file when the
    process running the query runs out of virtual memory, and deletes
    the file once the query is completed.

    You can define RDMS$BIND_WORK_FILE and specify a device name and
    directory. This enables the file to use resource identifiers for
    disk quota allocation.

    The following example shows how to assign the location of
    temporary files to a specific device and directory.

    $ DEFINE RDMS$BIND_WORK_FILE WORK$DISK:[RDB.WORK]
