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 MAY 05, 2020

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 the Slave 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 -- Master Agent
         agent2 -- Slave Agent
         agent3 -- Slave Agent
         agent4 -- Slave Agent
  2. Execute a Scenario using "startcmd.cmd OdiStartScen" command against the Master Agent "agent1".
  3. The Scenario will be balanced to Slave Agent "agent2", and executed by "agent2".
  4. Suspend the Slave Agent "agent2", and observe the " Read timed out" message in the "odiagent.log" of Master Agent "agent1".
  5. Resume the Slave 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 Slave Agents ("agent3" or "agent4" in this example).
