Depending on the license you purchase and the type of environment you install, you may deploy multiple Unwired Servers in a cluster.
If you have installed multiple servers as part of a clustered architecture, you must register these servers first. Only servers that are installed on the same host as Sybase Control Center are registered automatically. Once registered, remote servers also appear in the server list.
Servers are listed according to their cluster mode (that is, primary or secondary servers). Sybase Control Center automatically identifies the primary server and lists it first, followed by secondary servers.
