Cluster Controller Functions

The cluster controller server performs the following functions:

• Services new ODBC requests.

  When a new ODBC request comes into either the primary or secondary cluster controller server, the following events occur:

  • One of the cluster controller servers responds with a Siebel Analytics Server name and port number.
  • The ODBC client uses this returned Siebel Analytics Server name and port number to connect to the Siebel Analytics Server directly.
  • The ODBC request goes through the Siebel Analytics Server CLIENT_SERVER_PORT (9703 in Figure 2).
  • The session assignment goes to the primary cluster controller's CLIENT_CONTROLLER_PORT (9706 in Figure 2).
• Monitors the health of the Siebel Analytics Server nodes that participate in this cluster.
  • Each Siebel Analytics Server node loads the repository, so the server knows which database to get data from.
  • Siebel Analytics Server nodes use a heartbeat mechanism over TCP/IP.
  • The Siebel Analytics Server nodes include a Server Manager.
  • The Server Manager starts, stops, and restarts the Siebel Analytics Server for the cluster controller server.
