Configuring Backup Server Using sybcluster

You can configure Backup Server with sybcluster.

1. Start sybcluster.
   For example, to start sybcluster and specify Sybase Control Center agents on the nodes "blade1," "blade2," and "blade3," enter:

   sybcluster -U uafadmin -P -F "blade1:1234,blade2:2345,blade3:3456"

   Note: Sybase Control Center agents must be running on all nodes in the cluster to verify that the selected ports are available.
2. Connect to the cluster. For example, to connect to "mycluster," enter:

   connect to mycluster

3. If the cluster is not running, start it. Enter:

   start cluster

4. To create one or multiple Backup Servers for the cluster, enter:

   create backupserver

5. sybcluster prompts you:
   

   Do you want to create multiple Backup Servers? 

   1. If you answer Y, sybcluster prompts for:
      • A routing policy for the multiple Backup Servers. The choices are:

        • 1 – dedicated
        • 2 – round robin
      • Each Backup Server name. The default value is "cluster_name_BS." For example, "mycluster_BS."
      • The path to each Backup Server log file.
      • The listening port for each Backup Server.
   2. If you answer N, sybcluster prompts you to configure Backup Server on the hosts, one by one.
      • The Backup Server name. The default value is "cluster_name_BS." For example, "mycluster_BS."
      • The backup server listening port for each node in the cluster.

      Sybase recommends that you configure Backup Server on all nodes so that the Backup Server can be started on any node. In some cases where Backup Server is not configured on all nodes, Adaptive Server cannot start Backup Server when Backup Server is not running. This happens when the dump command is initiated on a node that does not have Backup Server configured.

      You can add or remove Backup Server from nodes at a later stage.
