KNIME Batch mode - failure (use of database connection)

Hello KNIME community,

I am trying to implement a batch to launch my workflow without having to open it.
I use database connector, then I do some simple manipulations on these data.
The workflow works when I launch it manually.

But when I launch the batch mode, only “warns” appear on the consoleLog, appart from an error :
Dataspec generated by configure does not match spec after execution

Details :
Here is the line in my batch doc : knime -nosplash -consoleLog -reset -application org.knime.product.KNIME_BATCH_APPLICATION -workflowDir=“workflow directory

Any pieace of help would be awesome :slight_smile:

Thank you and have a nice day !


hmmm. I have done the same thing and haven’t encountered anything similar. Your batch call seems fine. Does it start executing workflow at all?
