             DEC RdbExpert Version 1.0 and VAX DBMS Support

             DEC RdbExpert Version 1.0 was announced to provide database
             tuning support for both VAX Rdb/VMS and VAX DBMS database
             management systems. The DEC RdbExpert product will only
             support the tuning of VAX Rdb/VMS databases. Support for VAX
             DBMS will not be provided in the DEC RdbExpert product. If
             you have purchased this software to tune VAX DBMS databases
             please contact your Digital sales representative.

             DEC RdbExpert Workload Effort

             DEC RdbExpert is an excellent tool to aid the database
             administrator in tuning VAX Rdb/VMS databases. The DECtrace
             for VMS product can collect transaction and request
             information for use by DEC RdbExpert while applications
             are running. Thus, DECtrace helps in the acquisition of the
             database transaction workload prior to providing this data to
             DEC RdbExpert.

             It is important to note that the quality of the workload will
             have a direct influence on the efficiency of your database
             design and resultant application performance. The quality
             includes the effort that is put into ensuring that it is an
             accurate reflection of the transactions which will execute
             within the target environment.

             To aid the DEC RdbExpert user in creating accurate workloads,
             the DEC RdbExpert for VMS User's Guide has been written to
             provide a detailed discussion of the subject. Following the
             guidelines contained in this material will lead to better
             performance and more accurate designs.
