D -- TRANSACTION PROCESSING MONITOR (TPM) LICENSE SOFTWARE, MAINTENANCE, TRAINING, AND TECHNICAL SUPPORT SERVICES SOL 102590-97-A-0121 DUE 090897 POC Cindy Miller, (202) 268-5238 E-MAIL: Cindy Miller, cmille14@email.usps.gov. This is an addendum to previously issued CBD Submission No. 104555 dated 08/01/97. An internal pre-qualification was conducted by the U. S. Postal Service. Only two pre-qualified suppliers have received the solicitation. Detailed below is an explanation of the Postal Service's pre-qualification process. In essence, the qualification criteria were strictly based on Postal Service requirements. The Postal Service has a heterogeneous computing environment which includes multiple IBM or IBM plug compatible mainframes running CICS and IDMS applications, hundreds of UNIX servers with Oracle RDBMS applications, about 90 Digital Equipment VAX systems, and hundreds of Novel Netware servers. This environment will soon include up to 10,000 Microsoft NT severs and over 100,000 client workstations connected together through a TCP/IP network. The Postal Service intends to integrate this system and provide access to almost every host system from every workstation. The Postal Service has investigated numerous products and options and has concluded that a robust distributed transaction processing monitor (DTPM) is required to provide the needed connectivity and required functionality. This required functionality includes but is not limited to support for two-phase/multi-phase commits, decision support applications, message brokering, load balancing, as well as basic flat transaction functionality. Products that provide only a partial solution such as message-oriented middleware (MOM) can not be considered; rather a single integrated product suite is required. After careful review of the leading TPM marketplace suppliers and the Postal Service business requirements only two suppliers were found which could meet all the Postal Service technical and business objectives. These products and their companies are Tuxedo from BEA Systems, Inc. and Top End from NCR. The Postal Service will only accept proposal from pre-qualified suppliers. (0227)
