Introduction

In a JS7 - Agent Cluster jobs in workflows are assigned a Subagent Cluster that includes a Selection and Scheduling Mode of Subagents: 

• Subagent Clusters present a logical view of the way a given number of Subagents co-operate for job execution. 
  • Any number of Subagent Clusters can be configured using the same Subagents.
• The Selection makes use of one or more Subagents.
  • Subagents are used for job execution according to their ordering in the Selection.
  • A Subagent can be a member in one or more Subagent Clusters.
  • The configuration of Subagent Clusters is performed using the JOC Cockpit and is forwarded to the Controller and to the Director Agent.
• The Scheduling Mode is one of:
  • active-passive: execute jobs with the first Subagent and switch to the next Subagent only if the first Subagent becomes unavailable (fixed-priority clustering).
  • active-active: execute each next job on the next Subagent (round-robin clustering).
  • metrics-based: execute each next job on the Subagent that best matches metrics such as number of parallel tasks, CPU and memory consumption.
