Auxiliary Servers

You can configure the auxiliary servers such as Backup Server and XP Server with the sybcluster utility.

See Using Backup Server in a Clustered Environment in the Cluster Users Guide.

Backup Servers in a shared-disk cluster environment are available across all nodes of the cluster as a single Backup Server, or to operate on only one instance in the cluster. You can configure the Backup Server on any node of the cluster, and you can provide additional hosts and port numbers on which Backup Server can start if its current node goes down.

Execute the dump and load commands from any node in the cluster. Once issued, the local instance services the dump and load commands and routes them to the cluster’s Backup Server. The instances attempt to connect to Backup Server using the order specified in the interfaces file. If Backup Server is not running on any of the nodes in the cluster, the instance on which you issued the dump or load command starts Backup Server, if Backup Server is configured to run on this node in the interfaces file. If multiple Backup Servers are configured, the Backup Server is assigned based on whether the configuration is in dedicated or round-robin mode.

You can install and start Backup Server using sybcluster, which prompts you for required information.

The Backup Server binary ($SYBASE/$SYBASE_ASE/bin/backupserver) is installed when you install the Cluster Edition.

• Configuring Backup Server Using sybcluster
  You can configure Backup Server with sybcluster.
• Installing Job Scheduler
  All instances in the cluster share a single Job Scheduler. Set up Job Scheduler so that, in the event the instance on which it is running fails, Job Scheduler can fail over to another node.
• Configuring XP Server Using sybcluster
  Configure an XP Server for each instance in the cluster using the sybcluster create xpserver command, which performs the configuration steps automatically.
