Description of problem:
Oracle 10g database is certified to run on RHEL4 with no changes.
Unfortunately, my system can not use settings that work fine under RHEL3. Namely, I was able to use hugepages.
Under RHEL4 'cat /proc/meminfo' shows no usage of hugepages after Oracle instance starts. At same time a lot of swapping take place.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. start kernel with hugepages=500 parameter
2. start Oracle 10g
Actual Results: /proc/meminfo shows no usage of hugepages
Expected Results: some hugepages should be allocated by Oracle instance
Regarding to numerous postings about SLES9 kernel 2.6 works fine for Oracle inside hugepages
I've filed this problem with Oracle as TAR# 4405454.992

Sorry guys it seems that 'Refresh' button repopulated my bug.
Oracle forwarded me to Metalink document 262004.1 (Title: Configuring RHEL 3
and Oracle 9iR2 with Hugetlb and Remap_file_pages). It works for Oracle 10g
under RHEL 4.
This bug could be closed.
Closing as per comment #5.
