Starting a Node or Cluster

Start a cluster by starting its nodes. This step is optional for post installation.

Prerequisites

Add nodes to your cluster and configure them.

Task

If you are performing a basic installation for evaluation, or if you have not yet configured your clusters, you can skip this post-installation task. This information pertains to users ready to start clusters in their production environment. This may consist solely of the single-node cluster provided out of the box, but will most likely involve multiple clusters on different machines. For information on configuring clusters, see the Configuration and Administration Guide.

A cluster must be running before you can deploy projects to it. To start a cluster, start manager nodes first, then controller-only nodes. Follow these steps for each node in the cluster, where <node-name> represents the name of a node in the cluster.

Note: The directory from which a node is started becomes the working directory for the node. The node looks for the cluster.log.properties file in the working directory. SAP recommends that you start each node from a separate working directory.

To start a node, execute:

cd %ESP_HOME%\cluster\nodes\<node-name>
%ESP_HOME%\bin\esp_server.exe --cluster-node <node-name>.xml

(Optional) Use the cluster administration tool to start and manage projects. Execute a command of this form to enter the tool’s interactive mode:
esp_cluster_admin --uri=esp[s]://<host>:<port> --username=<user> [--password=<pass>]
Provide the cluster URI and your credentials to complete the command and begin working with cluster administration commands. Use the URI protocol esps when the cluster is SSL-enabled. For clusters that are not SSL-enabled, use the protocol esp.

Note: If you omit the password parameter when you call the esp_cluster_admin tool, Event Stream Processor prompts you for the password and hides it as you type, which improves security.
