java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist

what's the matter?

Start with the OracleEventProducer startup log and its Monitoring Query, especially the BMS_REPORT.sy$txlog and BMS_REPORT.sy$TESTPERSON references. Check the configured schema, table or view names, and database permissions; done means the producer starts without ORA-00942 and can read events. No source file or test is named in the issue.
