Automatic Data Definition Language (DDL) replication for HP NonStop SQL/MP databases will be available later this year through a new complimentary product, called NonStop SQL DDL Replicator (NonStop SDR), now under development. NonStop SDR software is targeted for availability in late summer 2008.
NonStop SDR is a new facility for capturing, replicating, and implementing NonStop SQL/MP DDL operations not currently replicated by NonStop Remote Database Facility (NonStop RDF) or other 3rd party replication software. It works with NonStop RDF to ensure that data and DDL replication is performed in sequence, to guarantee logical consistency.
At first release, NonStop SDR will target all Integrity NonStop and NonStop S-series server platforms using NonStop SQL/MP. The product requires no changes to application programs and causes no significant effect on performance, on the operation of primary system applications, or on transmission of database updates to the backup system. In addition, NonStop SDR provides low latency in keeping the backup database in sync with the primary database, thus ensuring rapid and precise takeover operations when needed.
Customers interested in the beta version of NonStop SDR for SQL/MP using NonStop RDF are encouraged to contact their local HP account team. This news is published on NonStop Computing websites. February 2008. |
