Remove Workflow Instance From Queue

Question

Hi Experts,
We encounter a problem in UCM workflow. Somehow the content of some workflow instances is no longer exists in the system (Don't know why), but the workflow instances are still active. This cause the cps portlet fails to render the approval portlet.
We have tried login as the workflow instance owner in UCM Admin page (http://host:16200/cs), and go to My Content Server > My Workflow Assignments, remove the offending workflow instance manually.
However we don't know how much workflow instances are affected, we would like to remove all offending workflow instances by a single administrative account i.e. "weblogic", but we found that we are not able to do this as the Content Items In Workflow "workflow_name" does not include the offending workflow.
Is there any SQL update to the data in the OCS schema to batch remove the workflow instances?

Hi Jiri,
Thanks for the suggestions, below are some more information on the issue.
if you can afford that, the easiest way how to get rid of running workflow instances is to disable an re-enable the criteria workflow(s) that contain it. Be aware that you will lose all workflow statuses of the disabled workflows.We can't afford that as it is a production system
Workflows, however, store workflow statuses on filesystem, so I'm not sure if database operations will be enough.I think so, we tried login as workflow owner, there is a function to "Remove workflow from queue" for specified workflow instance under All Active Workflows --> My Workflow Assignments. However after the removal of the workflow instances, we can't find any data modification in the OCS schema, related tables include WORKFLOWDOCUMENTS, WORKFLOWDOCATTRIBUTES, DOCUMENTS, DOCMETA, REVISIONS and REVCLASSES
by doing so, the admin should see the items - not in My Workflow Assignment, though. You will need to click the name of the wokflow and then, you should see all the items in the particular workflowYes, the admin i.e. "weblogic" can view all active workflow instances WITH content associated with it, but offending workflow instances (i.e. the one WITHOUT content somehow) do not show up.
We believe, if no things go wrong, that all active workflow instances can be found by running the following sql statement "select * from WORKFLOWDOCUMENTS;". However, in our case, workflow instances without content can be found using the same sql, but do not show up in UCM web UI login as "weblogic".
Last, but not least, you should analyse how come an item in a workflow could be deleted.We encountered this during high load (Generated by Stress Test Tool), without login UCM web UI as admin role to delete content.
the admin deleted the item in Repository Manager whilst it routed in a workflow.We tried using admin role to delete content in Repository Manager, it popup error when we tried to delete content which are in active workflow. We had to either Approve or Reject it before we can delete it (which I think the workflow maybe not in active state anymore, i don't know..)
See if any other suggestion I can get. Thanks for the input.
Thanks,
Ziho
