DSG RealSync database real-time replication software

A new generation of real-time heterogeneous heat disaster recovery-Oracle Database

IT systems have been running for a long time. On the one hand, their functions are getting greater and greater, and enterprise operations depend strictly on the normal operation of IT systems. On the other hand, as IT systems are becoming more and more complex, the data volume is growing, and the business types are becoming more and more diversified, IT personnel must face the following problems every day:

How to provide backup for the production system to achieve continuous operation of the disaster recovery system after the primary system fails!

How to make full use of the investment of the disaster recovery system to make the disaster recovery system play a greater role!

How can we implement disaster tolerance in a long-distance and low-bandwidth environment!

How to synchronize data between different hardware platforms!

 

DSG RealSync copies all data in the production database or some tables in real time to the target system through transaction replication. IT personnel can enhance the reliability of the new enterprise IT system through the target system. Because the target system created through real-time replication can be achieved;

 

Provide business continuity support. When the production database cannot work, you can take over the business on the target system in a timely manner.

This service provides support for service delivery, such as deploying services such as data query, statistical reports, and real-time data extraction from data warehouses to the target system, this greatly improves the efficiency of the information system on the master production end and the capability and efficiency of querying external information data.

 

The target database on the replication end is OPEN, and the data is real-time and supports real-time database access.

 

The disaster recovery database maintained by RealSync is always in the open state during the data replication process, and customers can achieve double benefits through the opened Oracle database; the open Oracle database provides data query, report, ETL extraction, and other functions to achieve business sharing.

 

Reliable Disaster Tolerance switchover

The Oracle database is enabled to ensure that the database can take over the business during service switching, so as to avoid the risk that the database may fail to start.

 

Avoid physical error Replication

DSG RealSync is a copy based on transaction commands. Therefore, operations that generate Bad blocks or files that are damaged will not be reproduced in the target system.

 

Supports long-distance replication and lower network bandwidth requirements and operation costs

RealSync transfers transaction data over the TCP/IP network, with no distance limit. Open technical platform to reduce network link purchase costs. At the same time, the transaction volume transmitted by RealSync over the network is only 1/3 of the Oracle Redo Log volume, further reducing the network bandwidth demand.

 

Supports replication between different hardware platforms

RealSync is a logic-level data replication technology. Therefore, for the production system and target system, its hardware platform can belong to different manufacturers, different models, or different operating systems, it provides users with flexible hardware platform selection space during system construction.

 

On-demand replication to meet business needs and reduce storage and network costs

According to the business logic, in many cases, only the required data table information is copied, which can reduce the cost of storage and network bandwidth.

 

Provides the first full synchronization and single-table repair functions without service interruption.

RealSync also provides support for the initial data loading function of the target system to smoothly load existing data on the Master System to the target database without interrupting the service. Other similar solutions require third-party solutions.

 

Low latency for production systems

DSG's real-time data replication technology does not need to use any database engine to obtain change data. Instead, it uses the database's own information to obtain and transmit the change information from the source system to the target system, this will not affect the performance of the production system.
