What kind of jobs are running in the system?
See the running transactions using this statement:
SELECT C.CONNECTION_ID, PS.STATEMENT_STRING FROM M_CONNECTIONS C JOIN M_PREPARED_STATEMENTS PS ON C.CONNECTION_ID = PS.CONNECTION_ID AND C.CURRENT_STATEMENT_ID = PS.STATEMENT_ID WHERE C.CONNECTION_STATUS = 'RUNNING' AND C.CONNECTION_TYPE = 'Remote'
To cancel session:
ALTER SYSTEM CANCEL SESSION <ConnectionID>
