inconsistent backup by backing up data files while a database is closed, either: / Immediately after the crash of an Oracle instance (or, in an Oracle RAC configuration, all instances) / After shutting down the database using SHUTDOWN ABORT Inconsistent backups are only useful if the database is in ARCHIVELOG mode and all archived redo logs created since the backup are available. * Open the database with the RESETLOGS option after finishing recovery: SQL> ALTER DATABASE OPEN RESETLOGS; QUESTION 159 Which three are direct benefits of the multiprocess, multithreaded architecture of Oracle Database 12c when it is enabled? (Choose three.) A. Reduced logical I/O B. Reduced virtual memory utilization C. Improved parallel Execution performance D. Improved Serial Execution performance E. Reduced physical I/O F. Reduced CPU utilization Correct Answer: BCF Section: (none) Explanation Explanation/Reference: Explanation: * Multiprocess and Multithreaded Oracle Database Systems Multiprocess Oracle Database (also called multiuser Oracle Database) uses several processes to run different parts of the Oracle Database code and additional Oracle processes for the users—either one process for each connected user or one or more processes shared by multiple users. Most databases are multiuser because a primary advantage of a database is managing data needed by multiple users simultaneously. Each process in a database instance performs a specific job. By dividing the work of the database and applications into several processes, multiple users and applications can connect to an instance simultaneously while the system gives good performance. * In previous releases, Oracle processes did not run as threads on UNIX and Linux systems. Starting in Oracle Database 12c, the multithreaded Oracle Database model enables Oracle processes to execute as operating system threads in separate address spaces. QUESTION 160 In order to exploit some new storage tiers that have been provisioned by a storage administrator, the partitions of a large heap table must be moved to other tablespaces in your Oracle 12c database? Both local and global partitioned B-tree Indexes are defined on the table. A high volume of transactions access the table during the day and a medium volume of transactions access it at night and during weekends. Minimal disrupt ion to availability is required. Which three statements are true about this requirement? (Choose three.) A. The partitions can be moved online to new tablespaces.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    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.
