In this issue, the editor will bring you about how to copy and hot switch data in Sybase. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

How the replication server works

The schematic diagram of the SYBASE replication server product operation is as follows:

Data replication in StandBy mode

In general, the replication node data changes with the primary node. If there is an error in the primary node, can I switch to the replication node? can the SYBASE replication server be similar to the dual hot standby mode?

In the SYBASE replication server environment, we can install the nodes as follows:

Under the condition of stable operation of the system, the master node Sybase and the replication node Sybase are synchronized, and the user will connect the master node through the intermediate node. When there is a problem with the primary node, the system controls the transaction problem through the "switching" of the intermediate node, and the replication node will be the primary node. In other words, it is similarly equivalent to a dual-computer hot standby system, which improves the availability of the system.

This is how to copy and hot switch data in Sybase shared by Xiaobian. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
