DBPLUS Data Replicator is software for data replication from Oracle databases to Oracle, Microsoft SQL Server and PostgreSQL. It aims to give real-time access to copies of production data with zero impact on the availability and performance of the systems which are the source of the data. According to the vendor Data Replicator can read over 80GB of changes contained in log files per hour. Information about changes made on the source database is read from transaction logs via the LogMiner tool available in Oracle databases. The only effect that the Replicator has on the source base is in the low load that results from the LogMiner tool. The DBPLUS Data Replicator software is able to read up to 2.5TB of daytime changes contained in log files. Information about changes made on the source database is read from transaction logs via the LogMiner tool available in Oracle databases.
