Starting and stopping nodes

The SPARKL nodes you have created can be stopped and started from terminal. To be able to log into the SPARKL® Developer Console, the nodes should be running.

Note: If experiencing issues, see section Troubleshooting or ask us questions in the chat window at the bottom-right corner of the web help.

Starting the nodes

About this task

The first time you execute the sse start command from a directory, it creates a node in that directory and starts the node. On each future execution, this command starts the node if it is not running.

Procedure

  1. Open a CLI.
  2. Navigate to the nodes' directory.
  3. Enter the following command to start the node: 
    sse start
  4. To validate that the node is up and running, execute either:
    • From the node's folder, sse ping
    • From any folder, sse list

Results

If the node is up and running, the terminal:
  • Returns a 'pong' message if you execute sse ping
  • Lists the node's directory if you execute sse list

Stopping the nodes

Procedure

  1. Open a CLI.
  2. Navigate to the nodes' directory.
  3. Enter the following command to stop the node: 
    sse stop
  4. To validate that the node is stopped, execute either:
    • From the node's folder, sse ping
    • From any folder, sse list

Results

If the node is stopped, the terminal:
  • Returns a 'not responding' message if you execute sse ping
  • Does not list the node's directory if you execute sse list
