Shareplex® is the industry's most sophisticated high-performance/high-availability data replication solution. With the features of less network occupancy, flexible configuration and quasi real time replication, it can solve many usability problems of key applications. In the past five years, the product technology has been successfully implemented by a large number of users around the world, becoming the most mature and leading high availability data replication solution for enterprise applications.
L??????? Capture data changes via redo log
The user's update to the data object, once written to the Oracle log, can be quickly captured by the Shareplex capture mechanism, even if the transaction may not have been executed. Shareplex realizes the perfect unification of replication speed and data accuracy. It fully complies with the principle of read consistency, and the target routines are the exact presentation of the source database. No other logical replication scenario can start data replication without waiting for the transaction to finish executing.
L??????? Less network footprint
Instead of capturing data changes through the Oracle engine, Shareplex directly reads and analyzes Oracle logs to find what needs to be replicated. Shareplex only replicates data changes, reducing bandwidth consumption. Through the continuous low load data stream, Shareplex can copy a large amount of data to the target system and reduce the network bandwidth demand.

Shareplex Combination Scheme
Shareplex is the only replication solution that can meet the stringent and highly available requirements on the 24x7. Shareplex transactional replication can be combined with physical refreshes of hot backup to achieve data synchronization for production systems without downtime, a patented technology in the Shareplex for Oracle standard configuration
L??????? Extensive heterogeneous environment support
Shareplex supports most Oracle versions on multiple platforms and is currently the only replication scheme that supports RAC or OPS online redo log. Shareplex for Rac/ops is both a Shareplex for Oracle cluster option and an independent product for Oracle cluster technology. Shareplex supports a variety of data types, including BLOBs, CLOB, long RAW, long, and user-defined types, and supports interoperability between different database versions. This means that users can copy data from Oracle 7.3.4 to RAC 9.2 on AIX, and vice versa
??? Oracle uses redo log to record data changes and updates, the Shareplex capture process monitors redo log to capture this change in replication targets, and updates are passed through the Shareplex queues on the source and target systems, and are not subject to database versions, Operating system and hardware platform type impact. If the replication fails, the Shareplex can either record the transaction to the queue for a delay or perform the necessary processing with archive log. After the update information is sent to the target system, it is immediately taken over by the process to generate the SQL statement to complete the replication of the source system in the target system.
? Its biggest feature is that the 2-side host database is started, can work at the same time, to ensure the reliability of the backup disaster-tolerant database. And the amount of replication data is small, and the network consumption is very low. Support heterogeneous hardware, software environment, incompatible version database.
