Creating and Starting the Cluster

You can configure and start the cluster server after successfully installing Adaptive Server.

1. Read Before Creating a Cluster.
2. Set the $SYBASE environment variable, and start the Sybase Control Center remote command and control agent on each node of the cluster.
3. Configure the cluster using Sybase Control Center, or the sybcluster utility. SAP recommends that you use either of these options to create and manage your shared-disk cluster; however, you can also manually configure and manage the cluster.

   If you have numerous clusters to set up, you can save your configuration parameters to a file, and use sybcluster to import them.

4. (Optional) Configure the auxiliary servers: XP Server, Backup Server, and Job Scheduler.

If the installation or start-up fails, see Cleaning Up After a Failed Installation.

• Differences Between Private and Shared Installations
  The installation process is different for private and shared installations.
• Cluster Edition Preinstallation Checklist
  Before you begin the installation process, identify your settings and determine how to set up your environment.
• Before Creating a Cluster
  After you install Sybase Control Center, you can create a cluster.
• Starting the Cluster When the Operating System Starts
  You can configure the host system to start the Adaptive Server cluster automatically; the operating system starts by running the Sybase Control Center agent on the host system and executing the sybcluster commands using a shell script.
• Cleaning Up After a Failed Cluster Installation
  If your cluster installation is unsuccessful, remove any residual files or operating system processes to prevent unexpected errors in subsequent installations.
• Auxiliary Servers
  You can configure the auxiliary servers such as Backup Server and XP Server with the sybcluster utility.
