NEW QUESTION 1
You created an encrypted tablespace:
1Z0-060 dumps exhibit
You then closed the encryption wallet because you were advised that this is secure.
Later in the day, you attempt to create the EMPLOYEES table in the SECURESPACE
tablespace with the SALT option on the EMPLOYEE column.
Which is true about the result?

  • A. It creates the table successfully but does not encrypt any inserted data in the EMPNAME column because the wallet must be opened to encrypt columns with SALT.
  • B. It generates an error when creating the table because the wallet is close
  • C. It creates the table successfully, and encrypts any inserted data in the EMPNAME column because the wallet needs to be open only for tablespace creation.

NEW QUESTION 2
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?

  • A. Examine the Active Session History (ASH) reports for the time period of the ETL or batch reporting runs.
  • B. Enable SQL tracing for the queries in the ETL and batch reporting queries and gather diagnostic data from the trace file.
  • C. Enable real-time SQL monitoring for ETL jobs and gather diagnostic data from the V$SQL_MONITOR view.
  • D. Enable real-time database operation monitoring using the DBMS_SQL_MONITOR.BEGIN_OPERATION function, and then use the DBMS_SQL_MONITOR.REPORT_SQL_MONITOR function to view the required information.
