- A. Restore the disk group with the exact configuration as the backed-up disk group, using the same disk group name, same set of disks, failure group configurations, and data on the disk group.
- B. Restore the disk group with the exact configuration as the backed-up disk group, using the same disk group name, same set of disks, and failure group configurations.
- C. Restore the disk group with changed disk group specification, failure group specification, disk group name, and other disk attributes.
- D. Restore metadata in an existing disk group by passing the existing disk group name as an input parameter.
Answer : B,C,D
Explanation:
Purpose -
The md_restore command restores disk groups from a metadata backup file.
Syntax and Description -
md_restore backup_file [--silent]
[--full|--nodg|--newdg -o 'old_diskgroup:new_diskgroup [,...]']
[-S sql_script_file] [-G 'diskgroup [,diskgroup...]']
backup_file
Reads the metadata information from backup_file.
--silent
Ignore errors. Typically, if md_restore encounters an error, it stops. Specifying this flag ignores any errors.
--full
Specifies to create a disk group and restore metadata.
--nodg
Specifies to restore metadata only.
--newdg -o old_diskgroup:new_diskgroup]
Specifies to create a disk group with a different name when restoring metadata. The -o option is required with
--newdg.
-S sql_script_file
Write SQL commands to the specified SQL script file instead of executing the commands.
-G diskgroup
Select the disk groups to be restored. If no disk groups are defined, then all disk groups are restored.
View the Exhibit and examine the disk groups created at the time of migrating the database storage to Automatic Storage Management (ASM).
Why does the FRA disk group initially have more free space even though both DATA and
FRA disk groups are provided with the same size?
- A. Because the FRA disk group will not support dynamic rebalancing
- B. Because the FRA disk group is not configured to support mirroring
- C. Because disks in the FRA disk group are not formatted at this stage
- D. Because the FRA disk group will support only a single size of allocation unit
Answer : B
You are managing an Oracle Database 11g instance and an Oracle Database 10g instance on the same machine. Both instances use the ASM instance as storage. Which statement regarding the ASM disk group compatibility attributes are true in this scenario? (Choose all that apply.)
- A. The database-compatibility version settings for each instance must be greater than or equal to the RDBMS compatibility of all ASM disk groups used by that database instances.
- B. RDBMS compatibility and the database version determines whether a database instance can mount the ASM disk group.
- C. The RDBMS compatibility settings for a disk group control the format of data structures for ASM metadata on the disk.
- D. ASM compatibility controls which features for the ASM will be enabled.
Answer : A,B,D
