Oracle 10g Release 2 (10.2) for Linux x86-64

Question

Hi All,
During installation - Oracle Database Configuration Assistance, I have got below error and thus I stuck. As per Metalink note 293988.1, this will be resolved if I do [root@localhos]# echo 1 > /proc/sys/vm/disable_cap_mlock . But problem is when I do this because I dont have /proc/sys/vm/disable_cap_mlock file in my system, it giving ¨bash: /proc/sys/vm/disable_cap_mlock: No such file or directory¨ error. So I am unable to get rid of this error. I also set SELinux Default and Current mode as permissible and rebooted it.
No use, Its giving same error.
ORA-27125: Unable to create shared memory segment.

Trust me I verified installtion guide and release notes atleast 20 times. I never had luck witht any thing. I was wondering how come edelivery.oracle.com packages (both Linux 64 bit Linux with upgrade to Unbreakable and Oracle 10g db version) is not workign for me. Finally below trick to the installed file could make my installation work(Ref link http://www.oracle-base.com/articles/10g/OracleDB10gInstallationOnFedora2.php) . In this I am setting DISABLE_HUGETLBFS to value 1. My only doubt is, does this have any impact on performance? Can some one relay on such tweeking for prod installtions? Ofcourse I am yet to go for commercial. At present I dont have ULN or metalink authorised access.
cd $ORACLE_HOME/bin
mv oracle oracle.bin
cat >oracle <<"EOF"
#!/bin/bash
export DISABLE_HUGETLBFS=1
exec $ORACLE_HOME/bin/oracle.bin $@
EOF
chmod +x oracle
