Implementation of Sybase data replication and thermal switching

The Sybase replication server (Sybase Replication server) is designed to meet the needs of an increasingly evolving Enterprise Client/server computer environment. Since the replication server has been widely used, it has become the foundation of enterprise-wide client/server application model.

How Replication Servers work

The diagram of the Sybase Replication Server product operation is as follows:

Data replication in StandBy mode

In general, replication node data changes following the master node. Can you switch to a replication node if there is an error in the primary node? Can Sybase replication servers be similar to dual-machine hot standby mode?

In the Sybase replication server environment, we can install each node as follows:

Under the condition of stable operation of the system, the master node Sybase and the replication node Sybase data 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 "switches" through the intermediate node to control the problem of the transaction, and the replication node is the main node. In other words, this is similarly equivalent to the dual-machine hot standby system, improve system availability.
