Oracle Database Administration from Zero to Hero - Practice - Automating Tasks with the Scheduler

This video tutorial covers the use of the scheduler in Oracle databases. It explains how to create a scheduler job to prepare a dashboard report, recreate the job using program and schedule objects, and monitor running jobs and logs. The tutorial includes practical steps for creating a scheduler job, verifying privileges, and managing job execution. It also discusses the use of SQL Developer for monitoring and retrieving job logs, providing insights into job performance and execution details.

What is the primary purpose of using a scheduler in Oracle databases?

• To automate repetitive tasks

• To enhance database security

• To improve data storage

• To increase network speed

What is the first step in creating a scheduler job for a dashboard report?

• Creating a new database

• Backing up the database

• Deleting old scheduler jobs

• Granting privileges to the user

Why is it necessary to enable a newly created scheduler job?

• To allow it to run as scheduled

• To increase its priority

• To delete old logs

• To change its frequency

What is the purpose of using Schedule and Program objects in creating a scheduler job?

• To separate job logic from scheduling

• To enhance security features

• To increase job execution speed

• To reduce database size

How can you verify that a scheduler job has successfully populated the report table?

• By restarting the database

• By reviewing the error logs

• By checking the table data

• By running a backup

What tool is used to monitor running scheduler jobs and retrieve job logs?

• Oracle Forms

• Oracle Reports

• Oracle Data Guard

• SQL Developer

What is the significance of the logging level in scheduler jobs?

• It determines the amount of information logged

• It increases job execution speed

• It enhances security features

• It reduces database size

What happens if the 'USE current session' is set to true when running a job?

• The command line waits until the job is finished

• The job is canceled

• The job runs in the background

• The job runs twice

What format do the program column values take for running scheduler jobs?

• JN, where N is an integer

• PN, where N is a string

• SN, where N is a date

• TN, where N is a boolean

What is the final step after verifying the scheduler job execution?

• Creating a new job

• Increasing job frequency

• Backing up the database

• Running clean up steps
