How to Drop A Scheduled Job In Oracle?

7 minutes read

To drop a scheduled job in Oracle, you can use the DBMS_SCHEDULER package or the Oracle Enterprise Manager.


If using the DBMS_SCHEDULER package, you can use the DROP_JOB procedure to remove a specific scheduled job from the database. You will need to specify the job name and optionally the job owner if the job belongs to a different user.


Alternatively, you can use the Oracle Enterprise Manager to drop a scheduled job through the GUI interface. You can navigate to the Jobs page, locate the scheduled job you want to drop, and then delete it from the list of jobs.


Make sure to confirm that you want to drop the scheduled job, as this action cannot be undone and will permanently remove the job from the database.

What is the impact of dropping a scheduled job in Oracle on the database?

Dropping a scheduled job in Oracle can have various impacts on the database:

  1. Loss of functionality: The job that was scheduled to run at specific intervals will no longer be executed, which may result in a loss of functionality or data processing in the database.
  2. Performance improvement: Dropping unnecessary or inefficient scheduled jobs can improve the overall performance of the database by reducing unnecessary overhead and resource utilization.
  3. Resource optimization: By removing unnecessary scheduled jobs, the database resources such as CPU, memory, and I/O can be optimized and allocated more efficiently to other critical tasks.
  4. Data integrity: If the scheduled job was responsible for maintaining data integrity or performing critical database operations, dropping it may lead to data inconsistencies or errors in the database.
  5. Maintenance simplification: Removing unnecessary scheduled jobs can simplify the database maintenance process by reducing the number of tasks that need to be monitored and managed.


Overall, dropping a scheduled job in Oracle database should be done carefully after considering its importance and impact on the overall database operations.
