[Version 5.0.2 and later]Creating backup clusters

Why and when to perform this task

You configure a backup cluster to handle requests if the primary cluster fails.

To configure a backup cluster, you must specify a name and an endpoint. The endpoint is called a "domain bootstrap address" and consists of a bootstrap host and port. The bootstrap host is the host that contains the deployment manager in which the backup cluster is configured. The bootstrap port is this same deployment manager's bootstrap port.

The primary cluster and the backup cluster must reside in separate cells. The backup cluster bootstrap host and port determine which cell contains the backup cluster.

Steps for this task

  1. Determine the bootstrap host and port of the backup cluster.
    1. Connect the administrative console to the deployment manager that contains the backup cluster.
    2. Click System Administration > Deployment Manager > End Points > BOOTSTRAP_ADDRESS to go to the BOOTSTRAP_ADDRESS endpoint page. The host and port for the BOOTSTRAP_ADDRESS instance is the host and port that the backup cluster will use.
    3. Connect the administrative console to the deployment manager that contains the primary cluster.
  2. Click Servers > Clusters > Backup Cluster to go to the Backup Cluster page.
  3. Ensure that the name of the backup cluster is the same as the containing server cluster.
  4. Click Domain Bootstrap Address and, on the Domain Bootstrap Address page, specify the backup cluster's deployment manager bootstrap host and port in the Host and Port fields. Then, click OK. The bootstrap host and port combined define a bootstrap address for the deployment manager.
    Note that, on the Domain Bootstrap Address page, you use the Configuration tab to statically define the backup cluster; the static value is consumed each time the deployment manager starts. You use the Runtime tab to define the backup cluster during run time only; when the deployment manager stops, the run-time backup cluster information is discarded.
  5. Click OK.
  6. Click Save on the administrative console taskbar and save your administrative configuration.
