You plan to install the Oracle Database 12c software. You want to use Oracle Automatic Storage Management
(ASM) for storage and Oracle Restart for managing components. Oracle Grid Infrastructure for a Standalone
Server is already installed on the server.
Which three statements must be true for successful installation of the Oracle Database 12c software?
A.
The OSBACKUPDBA, OSDGDBA, and OSKMDBA OS groups must be created.
B.
An operating system OSDBA group must be created for users with the SYSDBA system privilege.
C.
The Oracle Database 12c software owner and the Oracle Grid Infrastructure owner must belong to the
same Oracle Inventory Group.
D.
The Oracle Database 12c installation must have a separate Oracle inventory directory.
E.
An operating system OSOPER group be created for users with the SYSOPER system privilege.
confirmed.
B – You must create a OSDBA group the first time you install Oracle Database software on the system. This group identifies operating system user accounts that have database administrative privileges (the SYSDBA privilege).
C – Each Oracle software owner must be a member of the same central inventory oraInventory group, and they must have this group as their primary group, so that all Oracle software installation owners share the same OINSTALL system privileges. Oracle recommends that you do not have more than one central inventory for Oracle installations. If an Oracle software owner has a different central inventory group, then you may corrupt the central inventory.
E – You can choose to create a OSOPER group if you want a separate group of operating system users to have a limited set of database administrative privileges for starting up and shutting down the database (the SYSOPER privilege).
