Since I cannot obtain the original request to reply on I'm adding my thoughts here.

For that amount of transactions (60'000) I recommend to consider the use of a C/S TP monitor for reasons such as performance, scalability and  availability. Your applications would move to an N-tier architecture.

Developer/2000 can be easily integrated on behalf of interfaces to such a C/S TPM which are available at least for NCR's TOP END (see http://www.ncr.com/product/topend for further informations or simply contact me). In such a configuration Developer/2000 executes the Frontend and Business logics as far as useful, logical servers on the middle tier include the (rest of the) Business logic and the database accesses, and of course the third layer would be the oracle itself. You could still directly access oracle if appropriate (mixed 2- and N-tier). You also could integrate your existing MVS applications and data if needed. Integration of Internet/Intranet and other frontends, other DBMS's or other platforms would be easier as well.

Good luck
