Continually Leading
Shadowbase is Gravic's third-generation "real-time" replication solution for the NonStop (Tandem) platform. From the introduction of TMF-Auditor in 1984, Shadowbase has continued to lead the industry in providing low-latency replication solutions for the mission critical NonStop community. The key to the success of Shadowbase is its flexibility - its 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 not only provides extremely low-latency replication between homogeneous databases and systems, the Shadowbase solutions 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.
Shadowbase captures changes to NonStop SQL/MP and Enscribe databases from the TMF (NonStop TM/MP) audit trail files through HP supported audit read routines. These 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.
