Question
My UOW failed with the following error:
(9) Operation failed with failure category [Internal Error]
(10) [Caused by: Failed to get driver to determine driver type and support level (OperationFailedException)]
(11) [Caused by: Failed to instantiate driver CST-ab2d2376-d9c3-bb36-7255-90cd4b9c991c (DriverException)]
What could be the problem?
Answer
You want to check the worker.log for more information regarding the error.
If you find log messages similar to the following:

Then, that means at the worker server that executed the UOW (in the example, the worker server was IBMTEST2) does not contain the metadata files needed by the driver.
To resolve that, you need to sync the drivers directory (at least for those missing directories reported in the worker.log) across all the worker servers:
Once the task is completed, you could run the UOW again.
