cannot connetct to broken URL
I have a problem running a process on RapidMiner Server , that gives me error message:
'There was an error during the processing of the request: Ooops.. something went wrong when executing the process. Please contact your administrator. Cause: Uncategorized exception occurred during JMS processing; nested exception is javax.jms.JMSException: Could not connect to broker URL: tcp://DESKTOP-. Reason: java.net.ConnectException: Connection refused: connect'
and in executions i see this message
And the solution that i found is:
"This error message displayed on the Process Executions page, only disappears when the
ra_ent_jobsubmissionfailure table is empty. It is highly recommended that the
ra_ent_jobsubmissionfailure table should be emptied, as soon as you have identified the cause of process execution failure and corrected it."
But there isn't such table in my database.
How can i fix it?
Thank you in advance.
