Configuring Hugemem Kernel
The Red Hat Enterprise Linux 3 hugemem kernel is required to configure Oracle RDBMS to increase
the size of the buffer cache above the default 1.7 GB value. The Dell Installer automatically installs the
Red Hat Enterprise Linux 3 hugemem kernel. Change the default boot parameters in the bootloader
configuration file /etc/grub.conf to enable this option.
NOTE: It is recommended that the hugemem kernel be used only on systems having more than 16 GB of RAM.
This kernel has some overhead which may degrade the performance on systems with less memory.
