Extending Shadowbase Reliability Across the Enterprise
For almost two decades, Gravic, Inc. has been building low latency, highly reliable database replication solutions for the demanding Tandem, Compaq, and now HP NonStop marketplaces. Scores of Fortune 500 companies worldwide trust their priceless data to Shadowbase for solutions that range from business continuity to low latency heterogeneous system integration.
Gravic, Inc., a world leader in providing Total Replication Solutions® has extended its family of replication solutions by providing replication from Oracle® and Microsoft® SQL Server source databases on most UNIX® platforms and Microsoft Windows®. All of the characteristics of reliability, availability, and scalability of the Shadowbase for NonStop solutions are carried into the Open Source solution as are the full-featured flexible capabilities like sophisticated data transformation and mapping and the GUI Shadowbase Enterprise Manager™ command, control, and monitoring module.
Replication is supported from Oracle and SQL Server source databases to Oracle, Sybase®, Microsoft SQL Server, DB2, and HP NonStop target databases.
The Shadowbase for Open Source replication solutions capture change data from Oracle and SQL Server source databases using highly efficient C external routines in the Shadowbase Open Collector process. These changes are propagated to a Shadowbase Database of Change ("DOC") that serves as a stable queue in the event the target is unavailable. Data from the DOC can be replicated to another system using a Transaction Forwarding Server ("TFS") or directly to a database on the same system using a Transaction Replay Server ("TRS"). On a target UNIX or Windows system, the user has the option of applying changes directly to the target database or queuing changes and only applying committed transactions to the target.
