Install Oracle 11G Release 2 (11.2) on Oracle Linux 7 (OEL7)

Posted on May 3, 2014

This article presents how to install Oracle 11G on Oracle Enterprise Linux 7 (OEL7).

Read following article how to install Oracle Enterprise Linux 7: Install Oracle Linux 7 (OEL7) (for comfort set 2G memory for your virtual machine before proceeding with Oracle software installation).

Installation software is available on OTN version 11.2.0.1 or metalink 11.2.0.4. In this installation I’m presenting installation for 11.2.0.4 but for previous version 11.2.0.X it shouldn’t be different.

Oracle software which I verified

release 11.2.0.4

OS configuration and preparation

OS configuration is executed as root. To login as root just execute following command in terminal.

su - root

Add groups

--required groups /usr/sbin/groupadd -g 501 oinstall /usr/sbin/groupadd -g 502 dba /usr/sbin/groupadd -g 503 oper

Add user Oracle

/usr/sbin/useradd -u 502 -g oinstall -G dba,oper oracle

Change password for user

passwd oracle

Add kernel parameters to /etc/sysctl.conf

kernel.shmmni = 4096 kernel.shmmax = 4398046511104 kernel.shmall = 1073741824 kernel.sem = 250 32000 100 128 fs.aio-max-nr = 1048576 fs.file-max = 6815744 net.ipv4.ip_local_port_range = 9000 65500 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048586

Apply kernel parameters

/sbin/sysctl -p

Add following lines to set shell limits for user oracle in file /etc/security/limits.conf

oracle soft nproc 131072 oracle hard nproc 131072 oracle soft nofile 131072 oracle hard nofile 131072 oracle soft core unlimited oracle hard core unlimited oracle soft memlock 50000000 oracle hard memlock 50000000

The “/etc/hosts” file must contain a fully qualified name for the server.

<IP-address> <fully-qualified-machine-name> <machine-name>

For example.

127.0.0.1 oel7 oel7.dbaora.com localhost localhost.localdomain

Modify .bash_profile for user oracle in his home directory

# Oracle Settings export TMP=/tmp export ORACLE_HOSTNAME=oel7.dbaora.com export ORACLE_UNQNAME=ORA11G export ORACLE_BASE=/ora01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1 export ORACLE_SID=ORA11G PATH=/usr/sbin:$PATH:$ORACLE_HOME/bin export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib; export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib; alias cdob='cd $ORACLE_BASE' alias cdoh='cd $ORACLE_HOME' alias tns='cd $ORACLE_HOME/network/admin' alias envo='env | grep ORACLE' umask 022

Check which packages are installed and which are missing

rpm -q --qf '%{NAME}-%{VERSION}-%{RELEASE}(%{ARCH})\n' binutils \ elfutils-libelf \ elfutils-libelf-devel \ gcc \ gcc-c++ \ glibc \ glibc-common \ glibc-devel \ glibc-headers \ ksh \ libaio \ libaio-devel \ libgcc \ libstdc++ \ libstdc++-devel \ make \ sysstat \ unixODBC \ unixODBC-devel

In my case it returns following

binutils-2.23.52.0.1-12.el7(x86_64) elfutils-libelf-0.157-2.el7(x86_64) package elfutils-libelf-devel is not installed gcc-4.8.2-3.el7(x86_64) gcc-c++-4.8.2-3.el7(x86_64) glibc-2.17-36.el7(x86_64) glibc-common-2.17-36.el7(x86_64) glibc-devel-2.17-36.el7(x86_64) glibc-headers-2.17-36.el7(x86_64) package ksh is not installed libaio-0.3.109-9.el7(x86_64) package libaio-devel is not installed libgcc-4.8.2-3.el7(x86_64) libstdc++-4.8.2-3.el7(x86_64) libstdc++-devel-4.8.2-3.el7(x86_64) make-3.82-19.el7(x86_64) sysstat-10.1.5-1.el7(x86_64) package unixODBC is not installed package unixODBC-devel is not installed

There are two options to install missing packages

You need to install missing from dvd. Just mount it and install missing packages using rpm -Uvh command from directory <mount dvd>/Packages.

NOTE – I’m using x86_64 version of packages

rpm -Uvh elfutils-libelf-devel*.x86_64.rpm rpm -Uvh libaio-devel*.x86_64.rpm rpm -Uvh unixODBC*.x86_64.rpm rpm -Uvh ksh*.x86_64.rpm Run yum install command for missing packages --example howto install many packages yum install elfutils-libelf-devel \ ksh \ libaio-devel \ unixODBC*

Create directory structure for database software

ORACLE_BASE – /ora01/app/oracleORACLE_HOME – /ora01/app/oracle/product/11.2.0/db_1 mkdir -p /ora01/app/oracle/product/11.2.0/db_1 chown oracle:oinstall -R /ora01

Disable secure linux by editing the “/etc/selinux/config” file, making sure the SELINUX flag is set as follows. It requires REBOOT to be effective !!!

SELINUX=permissive

In Oracle Enterprise Linux 7 /tmp data is stored on tmpfs which consumes memory and is too small. To revert it back to storage just run following command and REBOOT machine to be effective.

systemctl mask tmp.mount

Install database software

Let’s start with database software installation as oracle user.

su - oracle --unzip software 11.2.0.4 unzip p13390677_112040_Linux-x86-64_1of7.zip unzip p13390677_112040_Linux-x86-64_2of7.zip --I defined 4 aliases in .bash_profile of user oracle to make --administration heaven :) [oracle@oel7 ~]$ alias envo cdob cdoh tns alias envo='env | grep ORACLE' alias cdob='cd $ORACLE_BASE' alias cdoh='cd $ORACLE_HOME' alias tns='cd $ORACLE_HOME/network/admin' --run alias command envo to display environment settings envo ORACLE_UNQNAME=ORA11G ORACLE_SID=ORA11G ORACLE_BASE=/ora01/app/oracle ORACLE_HOSTNAME=oel7.dbaora.com ORACLE_HOME=/ora01/app/oracle/product/11.2.0/db_1 --run alias command cdob and cdoh to check ORACLE_BASE, ORACLE_HOME [oracle@oel7 ~]$ cdob [oracle@oel7 oracle]$ pwd /ora01/app/oracle [oracle@oel7 db_1]$ cdoh [oracle@oel7 db_1]$ pwd /ora01/app/oracle/product/11.2.0/db_1 --run installation ./runInstall

14. I received following error during linking binaries

To fix this error edit $ORACLE_HOME/sysman/lib/ins_emagent.mk, search for the line

$(MK_EMAGENT_NMECTL)

and replace the line with

$(MK_EMAGENT_NMECTL) -lnnz11

then click “Retry” button

15. Database Configuration will start and create database for you.

16. You should see summary screen for your new database. Click “OK” button to continue with installation.

17. In the “middle” of installation you will be asked to run 2 scripts as user root. when scripts are executed just click “OK” button. Installation will proceed.

--execute scripts /ora01/app/oraInventory/orainstRoot.sh /ora01/app/oracle/product/11.2.0/db_1/root.sh

Post installation steps

Edit the “/etc/oratab” file to set restart flag for ORA11G to ‘Y’.

ORA11G:/u01/app/oracle/product/11.2.0/db_1:Y
