Which three statements are true about Oracle 12 RAC Database software installations?
A.
It is possible to install RAC database software on a one node cluster.
B.
It is possible to install multiple RAC database 12c software homes on the same cluster.
C.
The RAC database 12c software home and Grid infrastructure homes must be owned by separate OS users.
D.
The Cluster Verification Utility (CLUVFY) must be used to check the cluster before installing the RAC database software.
E.
The Cluster Verification Utility (CLUVFY) must be used to check the cluster after installing the RAC database software.
F.
The RAC database 12c software home and Grid Infrastructure homes must be owned by the same OS user.
Explanation:
A: An Oracle home is the directory in which you install Oracle Database binaries, and from which Oracle Database runs. Use Oracle Appliance Manager (through
oakcli commands) to create and manage multiple Oracle homes and databases on Oracle Database Appliance.
Oracle Database Appliance supports multiple Oracle Homes including different versions for Oracle Database 11g Release 2, 11gR2 and Oracle Database Release
12c Release 1.
D: You can use Cluster Verification Utility (CVU) to assist you with system checks in preparation for starting an upgrade.
F: The same user that owned the earlier release Oracle Grid Infrastructure software must perform the Oracle Grid Infrastructure 12c Release 1 (12.1) upgrade.
Before Oracle Database 11g, either all Oracle software installations were owned by the Oracle user, typically oracle, or Oracle Database software was owned by
oracle, and Oracle Clusterware software was owned by a separate user, typically crs.

Hello
Correct answers should be A,B and D.
F is incorrect, there is no need for DB and Grid home directories to have the same owner.
Then what about C.. grid and oracle two different OS users?
B – Why different 12c software on same cluster? Different version looks OK.
You can have multiple Oracle homes for Oracle Databases on your cluster. However, the Oracle RAC database software in these homes must be from a version that is equal to or before the version of Oracle Clusterware that is installed; you cannot have a version of Oracle Database running on Oracle Clusterware that was released after the version of Oracle Clusterware that you are running.
For example:
If your servers are running Oracle Grid Infrastructure 12c Release 1 (12.1), then you can have an Oracle Database 12c Release 1 (12.1) single-instance database running on one node, and separate Oracle RAC 11g Release 1 or 2, or Oracle RAC 12c Release 1 (12.1) databases also running on the cluster.
You cannot have Oracle Grid Infrastructure 11g Release 2 installed on your cluster, and install Oracle RAC 12c Release 1 (12.1).
