Introduction
Users have a number of options to organize their Subagent Clusters.for organizing their scheduling clusters.
- Agent Cluster: The operational layer of a Director Agent and a number of Subagents acting as an Agent Cluster.
- Subagent Clusters: The functional layer that groups a number of Subagents to different Subagent Clusters
This includes to use of a smaller number of operational Agent Clusters with a higher number of Subagent Clusters and vice versa.
For information on how to set up Agent Clusters and Subagent Clusters see see JS7 - Management of Agent Clusters
Capabilities
Subagent Clusters include the following capabilities.
Implicit Subagent Cluster per Subagent
When adding a Subagent JOC Cockpit can be instructed to add a cluster that holds the single Subagent.
offer a number of capabilities:
- A Subagent can be a member of any number of Subagent Clusters.
- A Subagent Cluster can include a single Subagent and it can include any number of Subagents.
- A Subagent Cluster defines fixed-priority or round-robin scheduling mode to switch between Subagents
- This allows to assign an individual Subagent to a job should the job be executed with this Subagent only.
- The name of the Subagent Cluster corresponds to the Subagent ID.
Unlimited Subagents per Cluster
Any number of Subagents can be added to a cluster.
- Adding more Subagents to a round-robin cluster allows unlimited horizonal scaling.
- Some might consider it paranoid to add a larger number of Subagents to a fixed-priority cluster, however, users are free to create a chain of Subagents that can replace each other.

One Cluster per Subagent
When adding a Subagent, the JOC Cockpit can be instructed to add a Subagent Cluster which holds the single Subagent.
- This allows a job to assigned to an individual Subagent if the job is to be executed only with this Subagent.
- The name of the Subagent Cluster corresponds to the Subagent ID.

Scheduling Modes
Subagents can be added for both fixed-priority and round-robin scheduling modes:
- fixed-priority: execute jobs with the first Subagent and switch to the next Subagent only if the first Subagent becomes unavailable (active-passive cluster).
- round-robin: execute each the next job on the next next Subagent (active-active cluster).
The JS7 allows to use mixed scheduling modes within the same cluster.

Strategies
Director Agent as Subagent Cluster Member
Users can add the a Director Agent to their Subagent Clusters:
- The Primary and Secondary Director Agents each include a Subagent that can be used to execute jobs.
- The Director Subagent can be added to any Subagent Clusters.
- Users can decide not to use the Director Agent for job execution but for orchestration of Subagents only in order to . This will guarantee the highest level of robustness.
Agent Clusters and Subagent Clusters
Users can apply different strategies to manage operational Agent Clusters and functional Subagent Clusters.
- A single or a few Agent Clusters can be used that with each holds holding a larger number of Subagent Clusters.
- Each Subagent Cluster selects a number of Subagents.
- The same Subagents can occur in any number of Subagent Clusters.
- The same Subagents cannot occur in more than one Agent Cluster.
- This scenario can be applied for load sharing between server nodes that act for a number of clustered applications.
- A larger number of Agent Clusters can be used that hold a single or a small number of Subagent Clusters.
- Agent Clusters are autonomous and are not related to each other.
- Each Agent Cluster is assigned an individual Director Agent that is optionally clustered.
- This scenario is preferably applied in a situation when communication between a Director Agent and Subagents should be limited to a few servers, for example for use of , when Agent Clusters are used in separate network zones.
