Show Log Of Each Task
You can usually find information about task execution, task status changes, and task failures in the task log. The job log reflects the results of local and remote jobs. The job log is used as the following two views of the data glossary:
*_SCHEDULER_JOB_LOG
*_SCHEDULER_JOB_RUN_DETAILS
Depending on the current log level, the scheduler can create entries in the job log whenever the last job is present and run it when it is created, deleted, activated, etc. Thus, since task a has a recurring schedule, the scheduler createst multiple entries in the procedure log, one for each instance of the task. Each journal contains entry information specific to a particular new run, such as the completion status of a job posting.
The following example shows the accounting log entries for a recurring function whose value is considered for the max_runs attribute:
SELECT job_name, job_class, operation, status FROM USER_SCHEDULER_JOB_LOG;JOB_NAME JOB_CLASS JOB STATUS----------- ------ -------------- - ---- ------TASK 1 CLASS 1 SUCCESSTASK 1 CLASS 1 SUCCESSTASK 1 CLASS 1 SUCCESSTASK 1 CLASS 1 SUCCESSASSIGNMENT 1 GRADE 1 COMPLETED
You can control how often information is logged to the task log by setting the logging_level attribute of the task or training session, if any. Table 29-11 shows the possible logging_level.

A log of the entries that a task will run is created only after the task succeeds, fails, or completes.
In the following example,The actual workbook entries for the entire job life cycle are shown. In this case, the logging level for the job class is typically LOGGING_FULL and the job is a solid, non-repeating job. However, after the first boost run, the job is released and executed again. It will then be stopped and removed.
