Continually Leading
The Shadowbase suite of software encompasses Gravic's third-generation real-time data replication solutions for the HP NonStop platform. From the introduction of TMF-Auditor in 1984, Shadowbase software continues to lead the industry in providing low-latency replication solutions for the mission critical NonStop community. The key to the success of Shadowbase deployments is its flexibility – the ability to provide continued value to our customers across a wide range of projects, solving a diverse set of business problems. Unlike many traditional disaster recovery replication products, Shadowbase software not only provides extremely low-latency replication between homogeneous databases and systems, Shadowbase software also provide incredible flexibility in selectivity, sophisticated data transformation and mapping, one-to-many or many-to-one configurations, replication between heterogeneous sources and targets, and true bi-directional replication between two or more live production systems and their databases.
A Shadowbase process called the Collector captures changes to NonStop SQL/MP and Enscribe databases from the TMF (NonStop TM/MP) audit trail files through HP supported audit read routines. The changes captured by the Shadowbase Collector process may be sent immediately via EXPAND or TCP/IP to a Consumer process on a target NonStop system for replication into a NonStop SQL/MP or Enscribe target database. Alternatively, these changes may be sent to Consumer process on the source system for replication over TCP/IP to a target Oracle, Microsoft SQL Server, or Sybase database on a UNIX or Windows system. On these systems the user has the option of directly updating the target or queuing changes and applying only committed transactions.
