How to execute Jobs and Job Chains with Agents

Scope

• Jobs and Job Chains can be executed with Agents. 
• There are various ways how to assign Agents to jobs and job chains.

Assignement of Agents

• Jobs and job chains are linked to Agents by means of Process Classes.
• A process class is assigned an Agent.
• A job or job chain is assigned a process class.
• A job chain can be configured to use a specific process class for subsequent job nodes. This enables a more flexible configuration than assigning the process class to a specific job that would be used for all jobs chains.

Use Cases

A Job Chain is assigned a default Agent for all Job Nodes

Explanations

• The job chain is assigned a default Agent.
• All jobs are executed with the same Agent.

Example

• Download job_chain_default_agent.zip
  • Extract the archive to your live folder, a directory job_chain_default_agent will be created.
• Adjust the process class 01_ProcessClass_Default_Agent to point to your default Agent installation:
  • The process class is configured for an Agent on the localhost and port 4445.

A Job Chain is assigned a default Agent and one Job is assigned a second Agent

Explanations

• The job chain is assigned a default Agent.
• One job is executed with the second Agent.

Example

• Download job_chain_default_second_agent.zip
  • Extract the archive to your live folder, a directory job_chain_default_second_agent will be created.
• Adjust the process class 01_ProcessClass_Default_Agent to point to your default Agent installation:
  • The process class is configured for an Agent on the localhost and port 4445.
• Adjust the process class 01_ProcessClass_Second_Agent to point to your second Agent installation:
  • The process class is configured for an Agent on a host Andreas-MacBook-Pro.local and port 4445.

A Job Chain is assigned a default Agent and a different Agent for the File Order Source

Explanations

• The job chain is assigned
  • an Agent for File Watching with a file order source and file order sink.
    • The Agent watches for incoming files and will move or remove the file with the file order sink.
  • a default Agent for executing the jobs in the job chain.

Example

• Download job_chain_default_file_watching_agent.zip
  • Extract the archive to your live folder, a directory job_chain_default_file_watching_agent will be created.
• Adjust the process class 01_ProcessClass_Default_Agent to point to your default Agent installation:
  • The process class is configured for an Agent on a host Andreas-MacBook-Pro.local and port 4445.
• Adjust the process class 01_ProcessClass_FileWatching_Agent to point to your File Watching Agent installation:
  • The process class is configured for an Agent on localhost and port 4445.
• Adjust the folders that are used for file watching:
  • The folder that is watched for incoming files: /tmp/jobscheduler/file/incoming/agent_file_watching
  • The folder that files are moved to on success: /tmp/jobscheduler/file/success
  • The folder that files are moved to on error: /tmp/jobscheduler/file/error


Jobs in a Job Chain are assigned different Agents

Explanations

• The job chain is not assigned an Agent.
• The Agents are assigned directly to jobs.
  • Jobs are executed by the assigned Agent independently from their use with different job chains.
  • Each job is executed with a different Agent (Cross-Platform Scheduling).
