Introduction

Any number of Agents can be clustered for high availability and scalability.Agent clustering is used to execute jobs with a JS7 Controller.

• Use of Standalone Agents:

  Explanation:

  • Agent ID: A unique identifier of the Agent. Uniqueness is applied for all Agents registered with the same Controller. This identifier cannot be changed later on.Use
  • Agent Name: The name of Agent Clusters:
  • available to commercial license holders,
  for details see JS7 - Management of Standalone Agents.an Agent is used for example when assigning the Agent to jobs. Similarly to the Agent ID the Agent Name has to be unique but can be changed later on.

  Enable/Disable Standalone Agent 

  Agents can be disabled and enabled. They are enabled by default.

  • When an Agent is disabled then it is no longer considered for job execution.
    • At the point in time of disabling the Agent will continue to complete any tasks running for jobs.
    • No new tasks are added to a disabled Agent.
    • Any newly added orders will wait for the Agent to become available and enabled. 
  • When a disabled Agent is enabled then it is automatically considered for next job executions.
    • For example, after a restart, with the Agent being enabled then orders will automatically continue in the workflow.

  Disabling of Agents can be used for example to manage maintenance windows on server nodes.

  • Users can apply the Search & Replace function for Agent assignments in a workflow that is available from the JS7 - Workflow Editor.
  • Users can apply the JS7 - Inventory Search function to replace Agent assignments across workflows.
  • Modified workflows have to be deployed to a Controller to make changes effective.
