Which technique should you use to minimize down time while plugging this non-CDB into the CDB? A. Transportable database B. Transportable tablespace C. Data Pump full export/import D. The DBMS_PDB package E. RMAN Correct Answer: B Section: (none) Explanation Explanation/Reference: Explanation: * Overview, example: - Log into ncdb12c as sys - Get the database in a consistent state by shutting it down cleanly. - Open the database in read only mode - Run DBMS_PDB.DESCRIBE to create an XML file describing the database. - Shut down ncdb12c - Connect to target CDB (CDB2) - Check whether non-cdb (NCDB12c) can be plugged into CDB(CDB2) - Plug-in Non-CDB (NCDB12c) as PDB(NCDB12c) into target CDB(CDB2). - Access the PDB and run the noncdb_to_pdb.sql script. - Open the new PDB in read/write mode. * You can easily plug an Oracle Database 12c non-CDB into a CDB. Just create a PDB manifest file for the non-CDB, and then use the manifest file to create a cloned PDB in the CDB. * Note that to plug in a non-CDB database into a CDB, the non-CDB database needs to be of version 12c as well. So existing 11g databases will need to be upgraded to 12c before they can be part of a 12c CDB. QUESTION 55 Your database supports an online transaction processing (OLTP) application. The application is undergoing some major schema changes, such as addition of new indexes and materialized views. You want to check the impact of these changes on workload performance. What should you use to achieve this? A. Database replay B. SQL Tuning Advisor C. SQL Access Advisor D. SQL Performance Analyzer E. Automatic Workload Repository compare reports Correct Answer: D Section: (none) Explanation Explanation/Reference: Explanation: You can use the SQL Performance Analyzer to analyze the SQL performance impact of any type of system change. Examples of common system changes include: • Database upgrades • Configuration changes to the operating system, hardware, or database • Database initialization parameter changes • Schema changes, such as adding new indexes or materialized views • Gathering optimizer statistics • SQL tuning actions, such as creating SQL profiles

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
