Multiple agents monitoring same queue and run in parallel

Hi all,

Please help me with the current requirement,

We are trying to implement a faster processing of pending records by increasing the number of agents.

We tried to create multiple agents but,we observed that the second agent will start only after the first has completed running so there was no considerable improvement in performance.

Is it possible to implement such that the first agent will pick the first 500 records (acquire lock) and the second agent will pick the next 500 and so on...

Please share your insight and suggestions to implement this scenario.

Thanks in Advance

Hi

Adjust the below system setting and see if that helps :

  • SLARefreshListEachIteration
  • SLAUnitsToProcess
  • SLAUnitsToRetrieve

Hi Mahindra

I would like to kmow the below pointers from you.

 

 

  •     Can you please let me know how you have configured multiple agents with screen shot and when you configured those(Before the queue items created or after)
  •     Which version of PRPC you are using ?
  •     What kind of agents you are trying to process.
  •     Please check the agent name in all the queue items and let us know(all queue items with the same agent name or two different agent names (pyAgentName is the table column))?
       
Please find my explanation for your requirement.
  •    With the current design of PRPC, it is possible to fix your problem with horizontal scaling environment(multi node environment).
  •    Till 7.2.2 instance we don't have any possibility to address this requirement with vertical scaling(Multiple agent with single node) . But I think from 7.2.2 onwards there is a possibility for vertical scaling as well.

Thanks & Regards

Saran Kolla

Hi Saran

 

Thanks for your reply

We are using 7.1.9 version , and we are trying to process advanced agents

We are trying to create a master agent and some child agents the master agent with queue the work items to child agents.

Reagarding multiple agents we are just naming the agent differently lik agent1,2,3,4 and the back end process is same for all.

7.2.2 i am not sure about vertical scaling in that verison.

Please do share your insights on this 

Thanks and Regards

Hello Mahindra,

I'm not sure I fully understand how you're trying to implement this. In theory, if you have a master agent that takes a work object and then does a queue-for-agent and based on a counter or similar does it to CustomAgent1, CustomAgent2 and so on that CustomAgent1 and CustomAgent2 shouldn't be running simultaneously. Of course the master agent has to feed the various child agents quick enough that they have work to do. Otherwise, you will see what appears to be one agent running at a time, and that's just because only one agent has work to do.

Can you add some screen shots of how you have these agents implemented so we can see where we might offer suggestions for improvement?

Thanks,
Mike

Thanks every one  for your suggestions we have implemented the above scenario with one master and 10 child agents, with master agent feeding child agents.

Thanks and Regard's
