SharePlex® is the most mature high-performance / high availability data replication solution in the industry. It has the characteristics of less network occupation, flexible, quasi-real-time replication, etc., can solve multiple usability issues of critical applications. In the past five years, the product technology has been successfully implemented by a large number of users around the world, and has become the most mature and leading high availability data replication solution for the company.
l ??????? Capture data changes through REDO LOG
User updates to data objects, once written in the Oracle log, can be quickly captured by Shareplex's capture mechanism, even if the transaction may have not been executed. Shareplex realizes the perfect unity of replication speed and data accuracy. It fully complies with the principle of reading, the target routine is the precise display of the source database. No other logical replication scheme can start data replication without waiting for transaction execution.
L ??????? network occupation
Shareplex does not capture data changes through the Oracle engine, but directly read and analyze Oracle logs, find out what you need to copy. Shareplex only copies data changes and reduces bandwidth occupation. By continuous low-load data stream, SharePlex can copy a large number of data to the target system, which reduces network bandwidth requirements.

SharePlex portfolio
SharePlex is the only replication scheme that can meet 24x7 strict high availability needs. SharePlex's transaction-level replication can be combined with the physical refresh of Hot Backup, and realizes the production system non-stop data synchronization. This is the patented technology in the SharePleX for Oracle standard. Environmental support
SharePLEX supports most Oracle versions on the multi-platform, and is currently unique to support RAC or OPS online Redo logs. SharePlex for RAC / OPS is both a cluster option for Shareplex for Oracle and a separate product for Oracle cluster technology. SharePLEX supports multiple data types, including BLOB, 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 record data change and update, the Shareplex capture process monitors Redo Log to capture the replication target. Variations, update information passes through the SHAREPLEX queue on the source system and target system, which is not affected by the database version, operating system, and hardware platform type. If the copy fails, SharePlex can delay the transaction to the queue, or can cooperate with the Archive log as necessary. After the update information is sent to the target system, immediately submit the process take over to generate the SQL statement, and complete the replication of the source system in the target system. • The biggest feature is that the host database of 2 is started, you can work simultaneously, ensuring the reliability of the backup disaster reduction database. Moreover, the amount of replicated data is small, and the network consumption is very low. Support heterogeneous hardware, software environment, compatible with universal version database.
