Upgrade Oracle DBA 11g to Oracle Database 12c — Question 48

Which three statements are true about a job chain?

Answer options

• A. It can contain a nested chain of jobs.
• B. It can be used to implement dependency-based scheduling.
• C. It cannot invoke the same program or nested chain in multiple steps in the chain.
• D. It cannot have more than one dependency.
• E. It can be executed using event-based or time-based schedules.

Correct answer: A, B, E

Explanation

Answers A, B, and E are correct because a job chain can indeed include nested chains, support dependency-based scheduling, and be executed through various scheduling methods. Options C and D are incorrect as they inaccurately describe the limitations of job chains; they can invoke the same program in multiple steps and can have more than one dependency.
