Symptoms

NOTE: In the examples below, user details / company name / address / email / telephone number represent a fictitious sample. Any similarity to actual persons, living or dead, is purely coincidental and not intended in any manner.

In Oracle Data Integrator (ODI), interface/mappings are not executing in multi-thread connections, even though Degree of Parallelism (DOP) is set on the target data server.

The interface/mapping knowledge modules are set, for example, to "LKM SQL Multi-Connect" and "IKM SQL to SQL Control Append."

The issue can be reproduced with the following steps:

  1. Define Data Server with Degree Of Parallelism configured in Topology manager.
  2. Create an interface/mapping with Target Data Store from the Topology Connection defined in the above step.
  3. Set LKM to "LKM SQL Multi-Connect" and IKM to "IKM SQL to SQL Control Append"
  4. Execute the interface/mapping and you will observe that session log displays DOP=1 even when DOP is configured as 10 in Target Data Server
