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

    TechMahi.com
      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.

          Hi,

          Make sure that you performed all pre-requisite steps successfully. Specially parameters related to kernel.

          May i know which version of oracle you are installing?

            Thanks for reply.
            I have taken care about parameters carefully one by one as per installation doc. But, I might have missed one or two prerequisite RPMs. I would again go through one by one and post the result here. Meantime, if anyone gone through similar situation and got resolved, please help me.
            Version: Oracle 10g Release 2 (10.2) for Linux x86-64. Chosen Basic Installation.
            Thank you.

              Hi;

              Please check first installation guide which is avaliable at:
              http://download.oracle.com/docs/cd/B19306_01/relnotes.102/b15666/toc.htm

              What is your linux version? Check Linux Certification part at upper link, than check *3 Preinstallation Requirements part*, be sure you have all related rpm and also kernel settings and retest issue

              Regard

                Also see MOS doc "Requirements For Installing Oracle10gR2 On RHEL 5/OEL 5 (x86_64) [ID 421308.1]" if you use RHE[SL]5 or OEL

                  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

                    If you installed the database successfully without any error then it won't be any problem. It won't create any impact on your database performance.

                    Also, upgrade your database into latest patch set 10.2.0.5.0 Check the below metalink note when you will get the access.

                      As already outlined, both installations are phased out. Enterprise Linux 5.5 is already too far ahead for the Oracle 10gR2 installer, which was designed for RHEL 3/4.

                      You will need to perform the usual preinstallation steps as outlined in the standard installation guide, but run the installer using:

                      <pre>
                      $ ./runInstaller -ignoreSysPrereqs
                      </pre>

                      If you have access to "My Oracle Support", review article ID 421308.1 "Requirements For Installing Oracle10gR2 On RHEL 5/OEL 5 (x86_64)".
