any changes for linux 6.2+ in configuring huge pages ( vs AnonHugePages )
I do not understand what if anything changes in planning huge page configuration for an 11.2 database going to be running in OL 6.2 ( and above ).
Normally one decides ( or should decide ) how much memory is going to be used for SGA and configures a huge page setting in /etc/sysctl.conf ...
There is now some other feature in 6 and above linux to support AnonHugePages so that applications running in the server ( and I guess operating system services etc ) can get huge pages without configuring them. For example if you now start up an 11.2.0.3.2 database running on 6.2 redhat compatible kernel and do not have "regular" huge pages configured looks like all the SGA eventually ends up in AnonHugePages territory. ( Works similarly if running uek2 kernel apparently also ).
If you have "regular" huge page configured in your system though as expected 11.2 starts up and uses those huge pages and leaves the AnonHugePages memory alone.
Is there relevant planning documentation available somewhere I have missed in doing preliminary research?
Any hints/tips/tricks or painful things to avoid already discovered in this area?
Thanks in advance!
