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/oracle
- ORACLE_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

I am getting the following error. Any advice on how to correct this?
Error in invoking target ‘install’ of makefile ‘/ora01/app/oracle/product/11.2.0/db_1/ctx/lib/ins_ctx.mk’. See ‘/ora01/app/oraInventory/logs/installActions2014-11-17_05-52-26AM.log’ for details.
I didn’t encounter this issue. It’s hard to say.Please verify you have installed all necessary libraries.
It happens on machines with new glibc. Static liniking fixed problem for me:
in ctx/lib/ins_ctx.mk
ctxhx: $(CTXHXOBJ)
-static $(LINK_CTXHX) $(CTXHXOBJ) $(INSO_LINK) /usr/lib64/stdc.a
Tak czy siak, fajna strona Lesio 😉
Are you sure you had this issue for version 11.2.0.4 not 11.2.0.1 ?
Tomasz
I tried 11.2.0.1 – 0.3. Don’t have metalink acces 🙂
But simpler solution would be:
yum install glibc.i686
For the sake of “ultra correctness”, should be
net.core.wmem_max = 1048576
instead of
net.core.wmem_max = 1048586
I suppose you meant 1M, but giving more memory to send buffers certainly won’t hurt 😉
Issues faced with oracle 11.2.0.4 on RHEL 7
===================================
Hi Guys,
Since you people had done the Installation on OL7/RHEL 7.
Can you please tell me did u faced any issues or any changes after or during the installation. Did you people find any performance issues/bugs.
We have an new build project, So just want to know can i recommended the 11.2.0.4 on RHEL 7(because in future i may need to upgrade db to 12C).
Regards,
Preethi
Amazing Tutorial … I had the same error in ins_ctx.mk using the 11.2.0.4, but the solution of krzysiek works perfectly.
Thank you all for the sharing the valuable information.
Best regards,
thank you you made me save lots of time ! with the agent issue
I have this problem
Checking monitor: must be configured to display at least 256 colors
>>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set. Failed <<<<
On user oracle i put export DISPLAY=my_ip:0.0
but i still have this problem.
Is there any extra package i need to install.
This is a basic RedHat install with only the packages u said i have to install.
execute as root xhost+
or install yum install xorg-x11-utils, I usually did installation via ssh -Y.
please help!!!!!
whenever i try to run the installer and click on next, the message does not show up correctly the screen fails to load up.
there is just a small line like thing and i cannot do anything further. my installation is just halted.
how do i get the gui to show up
I didn’t have this situation it’s very weird.
Kind Regards
Tomasz
Hi, I faced the same problem where my installer ‘hangs’ with the appearance of a small line.
I tried to install the db four times and was stuck by the same problem at the “Install product ” step. The 5th time, out of frustration I pressed “Enter” on my keyboard and was surprised to see the installation proceed.
Then I figured out what the line is.
Actually, it is a display problem. That small line is a minimized dialog box. Move your mouse directly on top of the line and the mouse pointer will change to a window resize icon. You can then resize the dialog box and proceed accordingly. I realized this after clicking the “Details” button on the “Install product” window, which popped up the small line again and as I moved my mouse over, the mouse pointer change and I resized the window.
Clicking enter upon appearance of the small line (minimized dialog box) will execute the default action which in most of the cases is “Continue”. That is why after hitting “Enter” out of frustration the first time, my installation proceeded.
I’m using OL 7.2 with KDE install.
Thank You Very Much… for this article it helps a lot.

Furquan
Friends !! I have another problem, I have tried to install OEL 7.2 using VMware 11 several times but when progress reaches at 68 % while linking TEXT BINARIES the installer window fades-out ( it looks like inactive) & still remain in the same state for several hours. What is this? No error message appears, No warning, nothing like this. I have tried the installation for more than 8 times but the same problem.
To fix popup “…” bug durring installation please use KDE instead of default Gnome.
yum groupinstall “KDE Desktop”
Installation works fine but after system restart database and services are down and can’t be started up (IDLE INSTANCE).
ERROR:ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Looks like some var issues but I double checked everything. Any ideas?
Thank you very much, the article is perfect ! I had troubles at first with the newly installed database but it was because I was using the 11.2.0.1
I am having the following Error:
“Error in invoking target ‘install’ of makefile ‘/ora11g/app/oracle/product/12.1.0/db_1/ctx/lib/ins_ctx.mk’. See ‘/ora11g/app/oraInventory/logs/installActions2018-02-14_10-38-24PM.log’ for details.”
How to Fix this issue. Please let me know.
thank you very much
