ODI 12c Agent Load Balancing: " Read timed out" Error Received and Causes the Scenario to be Re-executed Unexpectedly (Doc ID 2488817.1)

Last updated on APRIL 19, 2021

Oracle Data Integrator - Version and later
Information in this document applies to any platform.


When Oracle Data Integrator (ODI) 12c Agent Load Balancing is configured, and a linked Agent (which is executing a Scenario) is accidentally suspended...

... this causes:

   == and ==

This results in the same Scenario to be unexpectedly executed twice.

For replicating the behavior:
  1. Consider four standalone Agents on a same server, and configure the ODI Agent Load Balancing:

         agent1 -- Primary Agent
         agent2 -- linked Agent
         agent3 -- linked Agent
         agent4 -- linked Agent
  2. Execute a Scenario using "startcmd.cmd OdiStartScen" command against the Primary Agent "agent1".
  3. The Scenario will be balanced to linked Agent "agent2", and executed by "agent2".
  4. Suspend the linked Agent "agent2", and observe the " Read timed out" message in the "odiagent.log" of Primary Agent "agent1".
  5. Resume the linked Agent "agent2", and observe that the Scenario execution completes without any error.
  6. Also observe that the same Scenario is re-executed unexpectedly by another of the linked Agents ("agent3" or "agent4" in this example).
