Oracle job can be executed automatically before, but not later?

Check the job process of oracle through ps-ef | grep ora_j, but no related job process is found.

[oracle@ncb1dg ~] $ps-ef | grep ora_j

Oracle 13527 24508 0 15:13 pts/4 00:00:00 grep ora_j

View the all_jobs view to view details such as the last execution time and the next execution time of job

Select log_user,priv_user,schema_user,last_date,next_date,broken,interval from all_jobs where broken='N'

It is found that there is no interruption in jobs, and there is no hang to check the relevant job through DBA_JOBS_RUNNING.

By checking that the job_queue_processes of the current database is also greater than 0, job still cannot be executed automatically.

It was later discovered that it was caused by changing the OS time zone. Solution:

1. Restart the database.

2. Modify the OS time zone, modify the system time, and re-execute job.
