Looking through some tuning documentation about sysctl values as related to Oracle and other DB tuning bits, I noticed that the following don't exist anymore, and was curious where or if they were moved. /proc/sys/kernel/inode-max /proc/sys/vm/freepages In coincidence with this info, I was curious if anyone has tweaked the following and if it makes any difference, with regard to performance: /proc/fs/pagebuf /proc/sys/vm/pagebuf /proc/sys/vm/pagebuf/max_dio_pages /proc/sys/vm/page-cluster /proc/sys/vm/pagetable_cache -- Austin Gonyou Coremetrics, Inc.
