しかし、2.6.18-53.1.14.0.1.el5 と 2.6.18-53.1.13.0.1.el5 は違うし、kernel-2.6.18-53.1.13.0.1.el5と kernel-2.6.18-53.1.6.0.1.el5 も違う。ただし、kernel-2.6.18-53.1.6.0.1.el5 と 2.6.18-53.1.14.0.1.el5 と kernel-2.6.18-53.1.19.0.1.el5 との間で Oracle's ELのみの変更に違いはない。このため、kernel-2.6.18-53.1.19.0.1.el5への変更は、2.6.18-53.1.14.el5 と 2.6.18-53.1.14.0.1.el5の差分と、kernel-2.6.18-53.1.6.el5とkernel-2.6.18-53.1.6.0.1.el5の差分と同じし、kernel-2.6.18-53.el5 への Bug Fixes added by Oracleと同じ。ただし、2.6.18-53.1.13.0.1.el5 での Bug Fixes added by Oracleの一部は、2.6.18-53.1.14.el5 に含まれた。
このことを書いてなかったので、メモ。
RHEL5.1 Updated kernel package kernel-2.6.18-53.1.13.el5 Oracle's EL kernel-2.6.18-53.1.13.0.1.el5 - tmpfile::memoで
Oracle's ELのみの変更はkernel-2.6.18-53.1.6.0.1.el5に比べると増えてない。

428612 – RHEL 5.1 regression in hugepages due to pagetable sharing patchより
Opened by John Sobecki on 2008-01-14 01:45 EST [reply]
Description of problem:
We (Oracle) have had several customers upgrade to RHEL5.1 or Oracle EL 5.1
and report that hugepages on x86_64 are not properly freed after the database
SGA/instance is shutdown.
Version-Release number of selected component (if applicable):
2.6.18-53.el5
How reproducible:
100% everytime but you need an SGA > 4GB.
Steps to Reproduce:
1. Create an SGA > 4Gb and have hugepages allocated for it
2. Shutdown DB and all allocated hugepages will not be freed
3. Despite ipcs -a showing clean and ps -ef showing no orcl processes,
some of the SGA pages remain allocated
Actual results:
As above.
Expected results:
All allocated hugepages should be released upon DB shutdown.
Additional info:
Oracle had build a kernel without patch:
linux-2.6-mm-shared-page-table-for-hugetlb-page.patch
This was added per changelog entry:
- [mm] shared page table for hugetlb page (Larry Woodman ) [222753]
Without this patch, hugepages are properly released on DB shutdown.ということ。
