How do you modify Kernel Parameters to meet the minimum requirements for Oracle RAC?
A.
Pre-Oracle RAC 11g Release 2 manually changing the kernel Parameters is required to meet
Oracle RAC minimum requirements.
B.
With Oracle Grid Infrastructure / Oracle RAC 11g Release 2 fixup-scripts (CVU generated) can
be used to set the appropriate kernel Parameters.
C.
The Oracle Enterprise Manager can be used to modify kernel Parameters before the
Installation of the Oracle RAC stack.
D.
You do not need to change any Kernel Parameters for an Oracle RAC installation.
Explanation:
With Oracle Clusterware 11g release 2, Oracle Universal Installer (OUI) detects
when the minimum requirements for an installation are not met, and creates shell scripts, called
fixup scripts, to finish incomplete system configuration steps. If OUI detects an incomplete task,
then it generates fixup scripts (runfixup.sh). You can run the fixup script after you click the Fix and
Check Again Button.
You also can have CVU generate fixup scripts before installation.
