ERROR: Missing value for field nextstart in table job_queue_tbl for JobWorker DBCleaner

Post by tuxmin »

Hello everyone,

I updated to 25.04 today, and since then I see
Jobqueue status: 1 errorneous jobs (DBCleaner)
in OST status page.
Looking deeper into catalina.out, I found repeating messages like
2025-09-26 11:14:05,622: ERROR [quartzScheduler_Worker-3] com.agnitas.service.JobQueueService - ERROR: Missing value for field nextstart in table job_queue_tbl for JobWorker DBCleaner

So I checked the DB, and indeed, there is no date set for the DBCleaner

Code: Select all

MariaDB [openemm]> select ID,description,nextstart from job_queue_tbl;

That sort of fixed it, the messages went away, however, shortly after the set date, it starts all over again

Code: Select all

Looking at the timestamp in the DB, it is NULL again.

Please show us the complete entry for description "DBCleaner" and tell us which exact version of OpenEMM you use.

Class DBCleanerJobWorker is not part of OpenEMM. Please execute

Code: Select all

DELETE FROM job_queue_result_tbl WHERE job_id = (SELECT id FROM job_queue_tbl WHERE description = 'DBCleaner');
DELETE FROM job_queue_tbl WHERE description = 'DBCleaner';
INSERT INTO agn_dbversioninfo_tbl (version_number, updating_user, update_timestamp) VALUES ('21.10.279', CURRENT_USER, CURRENT_TIMESTAMP);
in your MariaDB database to fix this. We will check our DB scripts to make sure this job is removed from OpenEMM.

I see.

The 1st command excutes
MariaDB [openemm]> DELETE FROM job_queue_result_tbl WHERE job_id = (SELECT id FROM job_queue_tbl WHERE description = 'DBCleaner');
Query OK, 0 rows affected (0.002 sec)

but the 2nd fails
MariaDB [openemm]> DELETE FROM job_queue_tbl WHERE description = 'DBCleaner';
ERROR 1451 (23000): Cannot delete or update a parent row: a foreign key constraint fails (`openemm`.`job_queue_parameter_tbl`, CONSTRAINT `job_queue_parameter_tbl_ibfk_1` FOREIGN KEY (`job_id`) REFERENCES `job_queue_tbl` (`id`))

Sorry, I'm not sure how to resolve this... my SQL skills are limited...

Try

Code: Select all

DELETE FROM job_queue_parameter_tbl WHERE job_id = (SELECT id FROM job_queue_tbl WHERE description = 'DBCleaner');
