RMAN> BACKUP VALIDATE CHECK LOGICAL DATABASE ARCHIVELOG ALL; D: You can use the VALIDATE keyword of the BACKUP command to do the following: Check datafiles for physical and logical corruption Confirm that all database files exist and are in the correct locations. Note: You can use the VALIDATE option of the BACKUP command to verify that database files exist and are in the correct locations (D), and have no physical or logical corruptions that would prevent RMAN from creating backups of them. When performing a BACKUP...VALIDATE, RMAN reads the files to be backed up in their entirety, as it would during a real backup. It does not, however, actually produce any backup sets or image copies (Not A, not E). QUESTION 73 Which three statements are true concerning the multitenant architecture? (Choose three.) A. Each pluggable database (PDB) has its own set of background processes. B. A PDB can have a private temp tablespace. C. PDBs can share the sysaux tablespace. D. Log switches occur only at the multitenant container database (CDB) level. E. Different PDBs can have different default block sizes. F. PDBs share a common system tablespace. G. Instance recovery is always performed at the CDB level. Correct Answer: BDG Section: (none) Explanation Explanation/Reference: Explanation: B: * A PDB would have its SYSTEM, SYSAUX, TEMP tablespaces. It can also contains other user created tablespaces in it. * There is one default temporary tablespace for the entire CDB. However, you can create additional temporary tablespaces in individual PDBs. D: * There is a single redo log and a single control file for an entire CDB * A log switch is the point at which the database stops writing to one redo log file and begins writing to another. Normally, a log switch occurs when the current redo log file is completely filled and writing must continue to the next redo log file. G: instance recovery The automatic application of redo log records to uncommitted data blocks when an database instance is restarted after a failure.

Incorrect: Not A: * There is one set of background processes shared by the root and all PDBs. * High consolidation density. The many pluggable databases in a single container database share its memory and background processes, letting you operate many more pluggable databases on a particular platform than you can single databases that use the old architecture. Not C: There is a separate SYSAUX tablespace for the root and for each PDB. Not F: There is a separate SYSTEM tablespace for the root and for each PDB. QUESTION 74 You notice that the elapsed time for an important database scheduler Job is unacceptably long. The job belongs to a scheduler job class and window. Which two actions would reduce the job's elapsed time? (Choose two.) A. Increasing the priority of the job class to which the job belongs B. Increasing the job's relative priority within the Job class to which it belongs C. Increasing the resource allocation for the consumer group mapped to the scheduler job's job class within the plan mapped to the scheduler window D.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    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.
