Interfaces/Mappings are Not Executing in Multiple Threads when Degree of Parallelism is Configured on Target Data Server
(Doc ID 2367083.1)
Last updated on OCTOBER 04, 2022
Applies to:
Oracle Data Integrator - Version 11.1.1.7.0 and laterInformation in this document applies to any platform.
Symptoms
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:
- Define Data Server with Degree Of Parallelism configured in Topology manager.
- Create an interface/mapping with Target Data Store from the Topology Connection defined in the above step.
- Set LKM to "LKM SQL Multi-Connect" and IKM to "IKM SQL to SQL Control Append"
- 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
