Description Boris Mironov 2005-05-31 09:35:00 EDT

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)

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):
kernel-2.6.9-5.0.5.ELsmp

How reproducible:
Always

Steps to Reproduce:
1. start kernel with hugepages=500 parameter
2. start Oracle 10g
3. 
  

Actual Results:  /proc/meminfo shows no usage of hugepages

Expected Results:  some hugepages should be allocated by Oracle instance

Additional info:

Regarding to numerous postings about SLES9 kernel 2.6 works fine for Oracle inside hugepages

Comment 5 Boris Mironov 2005-06-05 21:27:16 EDT

Hello,

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.

Thanks,
Boris
