Method Detail

restart

void restart(java.lang.String workflowInstanceId)
      throws java.lang.Exception

Trigger restart a workflow instance that is in the error state. If workflow id is unknown or the workflow is not in broken state, nothing happens.

Parameters:

workflowInstanceId - workflow instance id as string

Throws:

java.lang.Exception - When some database operations fail, i.e. connection lost, transaction problems, ..

restartFiltered

void restartFiltered(WorkflowInstanceFilter filter)
              throws java.lang.Exception

Trigger restart all workflow instances that are in error state.

Parameters:

filter - the WorkflowInstanceFilter

Throws:

java.lang.Exception - When some database operations fail, i.e. connection lost, transaction problems, ..

restartAll

void restartAll()
         throws java.lang.Exception

Throws:

java.lang.Exception

deleteBroken

void deleteBroken(java.lang.String workflowInstanceId)
           throws java.lang.Exception

Entirely deletes the provided worklow instance if it is in the error state. If it currently holds a lock, the lock is released.

Parameters:

workflowInstanceId - workflow instance id as string

Throws:

java.lang.Exception - when the delete operation fails

deleteWaiting

void deleteWaiting(java.lang.String workflowInstanceId)
            throws java.lang.Exception

Throws:

java.lang.Exception

deleteFiltered

void deleteFiltered(WorkflowInstanceFilter filter)
             throws java.lang.Exception

Throws:

java.lang.Exception

getDBStorage

DBStorageMXBean getDBStorage()

getEngineClusterId

java.lang.String getEngineClusterId()

Gets EngineClusterId to make it possible grouping engines into engine cluster. Engines in one engine cluster should use same Database, in other case grouping will show incorrect data in copper monitoring

Returns:

the engineClusterId
