Enabling or Modifying Agent Schedules (Data-Agent-Queue)

Understanding how to enable or modify Agent Schedules (Data-Agent-Queue) is critical to managing your Pega deployment effectively. This article explains the different approaches that you can take to enable or modify Agent Schedules in Pega 7.3 and Pega 7.3.1.

Consider reading the author's back story on this article and its companion articles, PDN Article collection on Agents.

Prerequisites

Before you read this article, you should have fundamental knowledge of the Pega 7 Platform, especially the following Pega 7 concepts, tasks, and reference information:

  • How to develop rules for an application
  • Pega Agent concepts and terms and related topics
  • What Agents are available in Pega 7.3.1 and earlier releases and how to upgrade to Pega 7.3.1
  • How to create and schedule Agents in Pega 7.3 and Pega 7.3.1 on multiple nodes of a cluster (two or more Web Application Servers)
  • How to create, modify, and schedule Pega 7 Agent Queues
  • Information in the following PDN Articles:

Three approaches

To enable or modify Agent Schedules for your Pega 7 application, choose one of the following approaches:

Create Rule-Agent-Queue instances

  1. Create a new Rule-Agent-Queue (RAQ) in an application ruleset version.

The Master Agent wakes up at 10-minute intervals, detects a new RAQ, and creates the Data-Agent-Queue (DAQ), the Agent Schedule instance.

  1. You can now modify the DAQ without unlocking the ruleset so that you can change any of the following settings:
    • Pattern
    • Interval
    • Access Group
  2. For your updates to take effect, you must stop the Agents on the Agents landing page or in System Management Application and then restart them.

Update and migrate Rule-Agent-Queue instances

  1. Update Rule-Agent-Queue (RAQ) instances to include a new agent, a change in the agent or other attributes such as the following attributes:
    • Associated Node Type
    • Category
    • Mode
    • Activity
    • Parameters
  2. Change the Advanced settings:
    • Auto queue management
    • Running on one node
    • Delaying next startup time
    • Delaying the next runtime in the development (non-production) environment

The updated RAQ instances are then exported from the source environment and imported into the target environment. The Master Agent wakes up (10-minute interval), detects a change to the RAQ and updates or replaces the Data-Agent-Queue (DAQ), which is the Agent Schedule instance.

Any existing agent belonging to the ruleset is then updated (with the changes), removed (if removed from the RAQ), or skipped (no changes) with no user action required.

The Pega system then updates the System Management Application (SMA) > Agent Management > the Agents landing page with the changes introduced automatically.

Delete Data-Agent-Queue instances

  1. Delete the Data-Agent-Queue when there is an update to the Rule-Agent-Queue instances and you are not migrating the RAQ or the Ruleset Name and Version.
    Updates to the RAQ can include the following changes:
    • Include a new agent
    • Make a change to an agent
    • Other attributes (any combination of the first two updates)
  2. This requires a deletion of the corresponding Data-Agent-Queue (Agent Schedule) instances from the changed environment for the application ruleset associated with the agent.

The Master Agent wakes up (on a 10-minute interval), detects a change, and creates new Data-Agent-Queue (Agent Schedule) instances.
