Note:
1. Automatic statistics gathering is enabled by default when a database is created, or when a database is upgraded from an earlier database release. You can verify that the job exists by viewing the DBA_SCHEDULER_JOBS view:
SELECT * FROM DBA_SCHEDULER_JOBS WHERE JOB_NAME = 'GATHER_STATS_JOB';
2. The STATE column from DBA_SCHEDULER_JOBS provides information on the status of a particular job. It can be queried as follows:
SELECT job_name, state
FROM dba_scheduler_jobs
WHERE job_name='GATHER_STATS_JOB';
There are four types of jobs that are not running:
· FAILED
· BROKEN
· DISABLED
· COMPLETED
Note that if a job has recently completed successfully, but is scheduled to run again, the job state is set to 'SCHEDULED'. A job is marked as 'COMPLETED' if 'end_date' or 'max_runs' (in dba_scheduler_jobs) is reached.
