batch execution

KNIME Analytics Platform
1

I am attempting the learn how to use the batch execution of knime.  I started one batch job from the command line.  When I executed a second batch job with the same workflow I got the following error:

ERROR     main BatchExecutor     Workflow is locked by another KNIME instance

Does this mean that it is only possible to have a single execution of a given workflow running at a time?

Yes. But you export the workflow into a zip file and execute it from there (using -workflowFile). It will be extracted into a temporary directory and executed from there.
