Manually Setting Up and Managing the Cluster

If you set up the cluster manually, you cannot use the Adaptive Server plug-in or sybcluster to manage your cluster until you create and deploy the Unified Agent. See the Enabling sybcluster and the Plug-in After a Manual Configuration topic.

• Before You Begin
  Learn what to do before manually setting up and configuring the cluster.
• Configuring the Cluster Manually
  Sybase strongly recommends that the total number of engines in all instances does not exceed the number of CPUs.
• Configuring the Cluster for Automatic Takeover
  Configure the cluster to automatically recover from an abrupt total cluster failure.
• Starting the Cluster
  Start the cluster by starting all the instances associated with the cluster on each node in the cluster.
• Postconfiguration Tasks
  Learn what you should do after you have manually configured the server.
• Shutting Down the Cluster or the Instance
  Shutting down the cluster shuts down all the instances associated with the cluster.
• Reconfiguring the Cluster
  You can reconfigure a cluster to add instances, change trace flags, and so on. Edit the cluster input file and then create a new run file for the instance you intend to start first and that includes the dataserver with the cluster-input option. This option tells Adaptive Server to write the new configuration information to the quorum device.
• Enabling sybcluster and the Plug-in After a Manual Configuration
  To use sybcluster or the Adaptive Server plug-in to manage the cluster after a manual configuration, start a Unified Agent on each node in the cluster, and then deploy the connection agent to each node.
