You want to set up your RAC-enabled Database software so that you have the ability to perform
rolling software upgrades. Which configuration option must you use?
A.
At least five voting disks in the cluster
B.
At least five copies of the OCR
C.
Use a local home for files for software that will be upgraded
D.
With RAC, you can perform only rolling database and not-software upgrades.
Explanation:
Change directory to the Oracle Clusterware home. As root, run the preupdate.sh
script on the local node, and on all other nodes in the subset that you intend to upgrade. Use the
following command syntax, where clusterware_home is the path to the existing Oracle
Clusterware home, and installation_owner is the Oracle Clusterware installation owner:
/preupdate.sh -crshome clusterware_home -crsuser installation_owner
Incorrect:
Not D: Both rolling database and rolling clusterware upgrades are possible.
