In which situations will the ASM metadata backup help you recover the ASM disk
in a disk group?
(Choose all that apply.)
A. when one or more file directory paths are accidentally deleted from an ASM
disk group
B. when one of the disks in a disk group is accidentaly unplugged
C. when the data file on an ASM disk group gets corrupted
D. when one or more disks in an ASM disk group are lost
Answer: A,D
Explanation:
Oracle ASM metadata is the information that Oracle ASM uses to
control a disk group
and the metadata resides within the disk group. Oracle ASM metadata includes
the
following information:
■ The disks that belong to a disk group
■ The amount of space that is available in
a disk group
■ The filenames of the files in a disk
group
■ The location of disk group data file extents
■ A redo log that records information about
atomically changing metadata blocks
■ Oracle ADVM volume information
ASM metadata跟DATA不相关。
