Muniraju said...For RHEL 6 to make it work, I added below lines to "/etc/rc.local" file and rebooted the server.
if test -f /sys/kernel/mm/redhat_transparent_hugepage/enabled; then
echo never > /sys/kernel/mm/redhat_transparent_hugepage/enabled
if test -f /sys/kernel/mm/redhat_transparent_hugepage/defrag; then
echo never > /sys/kernel/mm/redhat_transparent_hugepage/defrag
That is in the article, but it is not the preferred method, as specified in the MOS note.
Eugene said...There is a bug on UEK 3 with hugepages=1g
The base bug for this issue is being tracked in 12609936.
Specifically, speaking with Oracle Database development, they responded as follows:
"We do not want to use 1G pages. This will not benefit the database, since the number of tlb entries are tiny.
I've put a comment to that effect at the start of that section. Thanks for the heads-up.

DO NOT ask technical questions here, that's what my forum is for!
