  • a. creating a child thread that has access to said second DBMS software, said child thread being used exclusively for generating object identifier numbers and for returning the same to said parent thread;

    b. creating a unique object identifier table, which is maintained by said child thread;

    c. in response to a request by said parent thread for a unique object identifier, said child thread generating n ones of said unique object identifiers and communicating values of said unique object identifiers to said parent thread; and
