Administering Clusters

Clustering provides scale-out support in Event Stream Processor, allowing you to add more nodes to a cluster as needed. Clustering lets users run multiple projects simultaneously, provides high availability and failover, and lets you apply centralized security and support for managing cluster connections.

• Clustering Architecture
  Event Stream Processor clusters are designed for simplicity and minimal need for interaction from administrators once started.
• Multiple Project Support
  Clustering lets users run multiple projects simultaneously using local and remote clusters.
• High Availability
  In Event Stream Processor, server clusters promote failure recovery and data redundancy. Event Stream Processor provides an added level of high availability at the project level called Active-Active mode.
• Project Deployment Options
  Project deployment options determine how your project is deployed in a cluster and how it functions at runtime. These parameters, including project options, active-active instances, failover intervals, and project deployment type options, are set in the CCR file manually or within Studio.
• Cluster Persistence and Caching
  Cluster persistence and caching are configured in the cluster configuration file.
• Centralized Security
  Security options for Event Stream Processor are configured locally through the cluster.
• Starting a Cluster
  Start a cluster so Studio users can deploy projects to it.
• Configuring Clusters
  Configure clusters to enhance performance by dividing processing work among a number of servers.
• Sample Project Configuration File
  Use this example project configuration CCR file to build and modify your XML-based project configuration file.
