Role of the Installer in Cluster ConfigurationLocate this document in the navigation structure

ESP uses a database-based cluster configuration, rather than a file-based cluster configuration. This database hosts configuration information for the cluster and is known as the cluster database. Several necessary components for the database-based configuration are installed during installation.

Cluster Database
  • When the ESP server is installed, the installer creates the cluster database.
  • The installer also deploys an initial cluster configuration consisting of a single node.
Passwords
  • The installer prompts you for the cluster database user name and password. The credentials you define here need not belong to an actual user, but are required for administrative-level access to this database.
  • The installer prompts you for the cluster password – this is also used as the password for the SYS_STREAMING user, which is used for logging into ESP Cockpit immediately after installing ESP .
File and Script Updates
  • The installer updates settings in the cluster bootstrap file (cluster.cfg).
  • The installer updates the script used to start the cluster database .
  • The installer updates the script used to start the initial node.
