Agents in Pega

 Agents

Standard Agents and Auto Queue Management 

Standard Agent is the legacy version of the Queue Processor in Pega 8.In Pega 8 if we want to call it in a case step we need to call a utility shape and pass the required parameters AgentRuleSet and AgentName.

How the Standard Agent work

1. Once the item is queued, this particular item will be pushed to PR_SYS_QUEUES table, where the entire WO data will be copied.
2. Then once the Agent wakes up it refers the PR_SYS_QUEUES table and picks each item one by one and executes.
3. Once the Queue item is successfully executed the item will be removed from the table.(Agent activity will be executed to the number of times equal to the number of items in the table)
4. Once the Agent finishes executing all the queue items it will go to sleep.

Once the queue item is moved to PR_SYS_QUEUES table it will the table will hold property value called pyItemStatus where its value will be Scheduled

if the agent activity fails while executing an item in the list that item will be updated in the table with the status of Broken-Process

This entire process is managed by PRPC there for its called Auto Queue Management.
