Which four statements are true concerning the upgrading of Oracle Grid Infrastructure 12c?

A. The ORACLE_HOME environment variable must be set to the Grid Infrastructure home directory in the installation owner's environment.

B. The upgrade must be done in-place.

C. The upgrade must be done out of place.

D. Upgrade validation may be done using the Oracle Universal Installer which in turn invokes the built-in cluster verification utility.

E. The cluster verification utility cluvfy.sh can verify that the cluster is ready for an upgrade.

F. The ORACLE_SID environment variable must be set to the SID of the ASM instance in the installation owner's environment.

G. The cluster verification utility cluvfy.sh can generate fixup scripts to run on all nodes of the cluster.

Correct Answer: A,C,E,G

Explanation/Reference:
Explanation:
A: Use the following command to start the installer, where the path you provide for the flag ORACLE_HOME is the location of the home directory from the earlier Oracle Clusterware installation For example:
$ cd /u01/app/12.1.0/grid/oui/bin
$ ./runInstaller -nowait -waitforcompletion -ignoreSysPrereqs -updateNodeList -silent CRS=true ORACLE_HOME=/u01/app/crs
C: Oracle Clusterware and Oracle ASM upgrades are always out-of-place upgrades. You cannot perform an in-place upgrade of Oracle Clusterware and Oracle ASM to existing homes.
E, G: Run the CVU manual script cluvfy.sh script to perform system checks and generate fixup scripts Incorrect Answers:
A, F: For the installation owner running the installation, if you have environment variables set for the existing installation, then unset the environment variables $ORACLE_HOME and $ORACLE_SID, as these environment variables are used during upgrade. For example:
$ unset ORACLE_BASE
$ unset ORACLE_HOME
$ unset ORACLE_SID
D: You can run upgrade validations in one of two ways:
Run OUI, and allow the CVU validation built into OUI to perform system checks and generate fixup

scripts
Run the CVU manual script cluvfy.sh script to perform system checks and generate fixup scripts.
