You are upgrading from an earlier version of Oracle Clusterware to Oracle Clusterware12cR1 and
want to store the OCR in an Oracle ASM disk group.
What are the correct steps required to accomplish this task?
A.
Set the ASM Compatibility attribute to 10.2.0.1 or later. Verify you are running the correct version
of Oracle Clusterware 12cR1 by issuing $crsctl query crsactiveversion Using srvctl create a disk group
appropriately sized for the OCR you are migrating to ASM. As root, issue #ocrcheck –add +DG_OCR
As root, issue # ocrcheck –delete old_ocr_location
B.
Set the ASM Compatibility attribute to 10.2.0.2 or later. Verify you are running the correct version
of Oracle Clusterware 12cR1 by issuing $crsctl query crsactiveversion Using acmca configure and
start Oracle ASM on all cluster nodes. Using asmca create a disk group appropriately sized for the
OCR you are migrating to ASM. As root, issue #ocrcheck –add +DG_OCR As root, issue # ocrcheck –
delete old_ocr_location
C.
Set the ASM Compatibility attribute to 10.2.0.2 or later. Verify you are running the correct version
of Oracle Clusterware 12cR1 by issuing $crsctl query crsactiveversion Using crsctl, configure and start
Oracle ASM on all cluster nodes. Using crsctl create a disk group appropriately sized for the OCR you
are migrating to ASM. As grid infrastructure owner, issue # ocrconfig –add +DG_OCR As grid
infrastructure owner, issue # ocrconfig –delete old_ocr_location
D.
Set the ASM Compatibility attribute to 10.2.0.2 or later.
Verify you are running the correct version of Oracle Clusterware 12cR1 by issuing $crsctl query
crsactiveversion Using acmca configure and start Oracle ASM on all cluster nodes. Using asmca
create a disk group appropriately sized for the OCR you are migrating to ASM. As root, issue
#ocrdump –add +DG_OCR As root, issue # ocrdump –delete old_ocr_location
Correct answer is B.

Migrating Oracle Cluster Registry to Oracle Automatic Storage Management
1.Ensure the upgrade to Oracle Clusterware 12c is complete. Run the following command to verify the current running version:
$ crsctl query crs activeversion
2.Use the Oracle ASM Configuration Assistant (ASMCA) to configure and start Oracle ASM on all nodes in the cluster.
3.Use ASMCA to create an Oracle ASM disk group that is at least the same size of the existing OCR and has at least normal redundancy.
4.To add OCR to an Oracle ASM disk group, ensure that the Oracle Clusterware stack is running and run the following command as root:
# ocrconfig -add +new_disk_group
5.To remove storage configurations no longer in use, run the following command as root:
# ocrconfig -delete old_storage_location
Or, all options are incorrect…

Note:
If you upgrade from a previous version of Oracle Clusterware to Oracle Clusterware 12c and you want to store OCR in an Oracle ASM disk group, then you must set the ASM Compatibility compatibility attribute to 11.2.0.2, or later.
B….. but compatible attribute cannot be 10.2
All incorrect I’m afraid.
Command for the last two steps should be ocrconfig, which only appears in C!
Yes, it should be oraconfig, but started with root (not GI owner).
If you upgrade from a previous version of Oracle Clusterware to Oracle Clusterware 12c and you want to store OCR in an Oracle ASM disk group, then you must set the ASM Compatibility compatibility attribute to 11.2.0.2, or later.
C is correct
B… is incorrect because the utility #ocrcheck –add +DG_OCR is not possible, the correct option is # ocrconfig -add +new_disk_group
