Question 103/170
You upgraded from a previous Oracle database version to Oracle Database version to Oracle Database 12c. Your database supports a mixed workload. During the day, lots of insert, update, and delete operations are performed. At night, Extract, Transform, Load (ETL) and batch reporting jobs are run. The ETL jobs perform certain database operations using two or more concurrent sessions.
After the upgrade, you notice that the performance of ETL jobs has degraded. To ascertain the cause of performance degradation, you want to collect basic statistics such as the level of parallelism, total database time, and the number of I/O requests for the ETL jobs.
How do you accomplish this?

Correct Answer: D
* Monitoring database operations
Real-Time Database Operations Monitoring enables you to monitor long running database tasks such as batch jobs, scheduler jobs, and Extraction, Transformation, and Loading (ETL) jobs as a composite business operation. This feature tracks the progress of SQL and PL/SQL queries associated with the business operation being monitored. As a DBA or developer, you can define business operations for monitoring by explicitly specifying the start and end of the operation or implicitly with tags that identify the operation.
