|
| 6. | If a database is in ARCHIVELOG mode, which of the following statements are true before the Log Writer (LGWR) can reuse a filled online redo log file? |

| 7. | A company was consolidated into one office building, so the very large EMPLOYEES table no longer required the BUILDING_LOCATION column. The DBA decided to drop the column using the syntax below: ALTER TABLE hr.employees DROP COLUMN building_location CASCADE CONSTRAINTS; Dropping this column turned out to be very time consuming and required a large amount of undo space. What should the DBA do to minimize the problem regarding time and undo space consumption? |
| a. | | Mark the column as UNUSED and remove the column at a later time when less activity is on the system |
| b. | | Drop all indexes and constraints associated with the column prior to dropping the column |
| c. | | Mark the column INVALID prior to beginning the drop to bypass undo and remove the column using the DROP UNUSED COLUMNS command |
| d. | | Add a checkpoint to the DROP UNUSED COLUMNS command to minimize undo space
|

|
|
|
|
| 8. | The STARTUP MOUNT command was issued. What happens when the instance is started and the database is mounted? |
| a. | | The SGA is allocated |
| b. | | The background process is started |
| c. | | The existence of the datafile is verified |
| d. | | The existence of the online redo log file is verified
|
|
|
|
|
|
|
| 9. | Intermittent hardware problems are being experienced with the disk drive on which the control file is located. It is decided to multiplex the control file. While the database is open, the following steps were performed: 1. A copy of the control file was made using an operating system command. 2. A new file name was added to the list of files for the CONTROL FILES parameter in the text initialization parameter file, using an editor. 3. The instance was shut down. 4. The STARTUP command was issued to restart the instance, mount, and open the database. The instance starts, but the database mount fails. Why? |
| a. | | The control file was copied before shutting down the instance |
| b. | | An operating system command was used to copy the control file |
| c. | | The Oracle server does not know the name of the new control file |
| d. | | A new control file name was added to the CONTROL_FILES parameter before shutting down the instance
