Oracle Database 12c Release 1 (12.1) Installation On Oracle Linux 7 (OL7)
Oracle Linux 7 is a production release, but the Oracle Database is only supported on it from Oracle Database 12c (184.108.40.206) onward. This installation should not be used for a real system when using database versions prior to 220.127.116.11.
This article describes the installation of Oracle Database 12c Release 1 (12.1) 64-bit on Oracle Linux 7 (OL7) 64-bit. The article is based on a server installation with a minimum of 2G swap and secure Linux set to permissive. An example of this type of Linux installation can be seen here.

Download the Oracle software from OTN or MOS depending on your support status.
- OTN: Oracle Database 12c Release 1 (126.96.36.199) Software (64-bit).
- edelivery: Oracle Database 12c Release 1 (188.8.131.52) Software (64-bit)
Unzip the files.
unzip linuxamd64_12102_database_1of2.zip unzip linuxamd64_12102_database_2of2.zip
You should now have a single directory called "database" containing installation files.
The "/etc/hosts" file must contain a fully qualified name for the server.
<IP-address> <fully-qualified-machine-name> <machine-name>
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 192.168.0.215 ol7.localdomain ol7
Set the correct hostname in the "/etc/hostname" file.
Oracle Installation Prerequisites
Perform either the Automatic Setup or the Manual Setup to complete the basic prerequisites. The Additional Setup is required for all installations.
If you plan to use the "oracle-rdbms-server-12cR1-preinstall" package to perform all your prerequisite setup, issue the following command.
# yum install oracle-rdbms-server-12cR1-preinstall -y
Earlier versions of Oracle Linux required manual setup of the Yum repository by following the instructions at http://public-yum.oracle.com.
It is probably worth doing a full update as well, but this is not strictly speaking necessary.
# yum update -y
It's worth running the all the YUM commands listed in the manual setup section. Depending on the OS package groups you have selected, some additional packages might also be needed.
If you have not used the "oracle-rdbms-server-12cR1-preinstall" package to perform all prerequisites, you will need to manually perform the following setup tasks.
Add or amend the following lines in the "/etc/sysctl.conf" file.
fs.file-max = 6815744 kernel.sem = 250 32000 100 128 kernel.shmmni = 4096 kernel.shmall = 1073741824 kernel.shmmax = 4398046511104 net.core.rmem_default = 262144 net.core.rmem_max = 4194304 net.core.wmem_default = 262144 net.core.wmem_max = 1048576 fs.aio-max-nr = 1048576 net.ipv4.ip_local_port_range = 9000 65500
Run the following command to change the current kernel parameters.
Add the following lines to the "/etc/security/limits.conf" file.
oracle soft nofile 1024 oracle hard nofile 65536 oracle soft nproc 2047 oracle hard nproc 16384 oracle soft stack 10240 oracle hard stack 32768
The following packages are listed as required, including the 32-bit version of some of the packages. Many of the packages should be installed already.
yum install binutils -y yum install compat-libstdc++-33 -y yum install compat-libstdc++-33.i686 -y yum install gcc -y yum install gcc-c++ -y yum install glibc -y yum install glibc.i686 -y yum install glibc-devel -y yum install glibc-devel.i686 -y yum install ksh -y yum install libgcc -y yum install libgcc.i686 -y yum install libstdc++ -y yum install libstdc++.i686 -y yum install libstdc++-devel -y yum install libstdc++-devel.i686 -y yum install libaio -y yum install libaio.i686 -y yum install libaio-devel -y yum install libaio-devel.i686 -y yum install libXext -y yum install libXext.i686 -y yum install libXtst -y yum install libXtst.i686 -y yum install libX11 -y yum install libX11.i686 -y yum install libXau -y yum install libXau.i686 -y yum install libxcb -y yum install libxcb.i686 -y yum install libXi -y yum install libXi.i686 -y yum install make -y yum install sysstat -y yum install unixODBC -y yum install unixODBC-devel -y yum install zlib-devel -y yum install zlib-devel.i686 -y
Create the new groups and users.
groupadd -g 54321 oinstall groupadd -g 54322 dba groupadd -g 54323 oper #groupadd -g 54324 backupdba #groupadd -g 54325 dgdba #groupadd -g 54326 kmdba #groupadd -g 54327 asmdba #groupadd -g 54328 asmoper #groupadd -g 54329 asmadmin useradd -u 54321 -g oinstall -G dba,oper oracle
Uncomment the extra groups you require.
The following steps must be performed, whether you did the manual or automatic setup.
Set the password for the "oracle" user.
Set secure Linux to permissive by editing the "/etc/selinux/config" file, making sure the SELINUX flag is set as follows.
Once the change is complete, restart the server or run the following command.
# setenforce Permissive
# systemctl stop firewalld # systemctl disable firewalld
Create the directories in which the Oracle software will be installed.
mkdir -p /u01/app/oracle/product/184.108.40.206/db_1 chown -R oracle:oinstall /u01 chmod -R 775 /u01
Putting mount points directly under root is typically a bad idea. It's done here for simplicity, but for a real installation "/" should be reserved for the OS.
Unless you are working from the console, or using SSH tunnelling, login as root and issue the following command.
Add the following lines at the end of the "/home/oracle/.bash_profile" file.
# Oracle Settings export TMP=/tmp export TMPDIR=$TMP export ORACLE_HOSTNAME=ol7.localdomain export ORACLE_UNQNAME=cdb1 export ORACLE_BASE=/u01/app/oracle export ORACLE_HOME=$ORACLE_BASE/product/220.127.116.11/db_1 export ORACLE_SID=cdb1 export PATH=/usr/sbin:$PATH export PATH=$ORACLE_HOME/bin:$PATH export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib
Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.
DISPLAY=<machine-name>:0.0; export DISPLAY
Start the Oracle Universal Installer (OUI) by issuing the following command in the database directory.
Proceed with the installation of your choice.
If you are doing an installation for an Enterprise Manager repository, remember to do an advanced installation and pick the ALT32UTF8 character set.
Check out the notes below for how to deal with potential errors that may arise during the installation.

Edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.
Only follow these notes if you are attempting the install using 18.104.22.168, there are a number of things that will need to be fixed along the way. These are not necessary for a 22.214.171.124 installation, as it completes cleanly.
The following steps need to be considered during the installation.
When clicking "Next" on the "Download Software Updates" screen you will get the following message. Click the "Yes" button.
"[INS-13001] Environment does not meet minimum requirements. Are you sure you want to continue?
During the linking phase, you will see the following error.
Error in invoking target 'links proc gen_pcscfg procob' of makefile '/u01/app/oracle/product/126.96.36.199/db_1/precomp/lib/ins_precomp.mk'. See '/u01/app/oraInventory/logs/installActions2014-04-26_08-07-04PM.log' for details.
To fix it, do the following:
rm -rf $ORACLE_HOME/lib/stubs/* cp $ORACLE_HOME/rdbms/lib/env_rdbms.mk $ORACLE_HOME/rdbms/lib/env_rdbms.mk.orig
Perform the following modifications to the "$ORACLE_HOME/rdbms/lib/env_rdbms.mk" file.

Click the "Retry" button.
Later, you might see the following error.
Error in invoking target 'install' of makefile '/u01/app/oracle/product/188.8.131.52/db_1/ctx/lib/ins_ctx.mk'. See '/u01/app/oraInventory/logs/installActions2014-04-26_08-07-04PM.log' for details.
To fix it, do the following:
rm -rf $ORACLE_HOME/lib/stubs/* cp $ORACLE_HOME/ctx/lib/env_ctx.mk $ORACLE_HOME/ctx/lib/env_ctx.mk.orig
Perform the following modifications to the "$ORACLE_HOME/ctx/lib/env_ctx.mk" file.
# Line 154 # FROM: LINK=$(LDCCOM) # TO : LINK=$(LDCCOM) --Wl,--no-as-needed
Click the "Retry" button.
Due to the issues during the linking phase, it probably makes sense to do a relink once the installation is complete.
dbshut $ORACLE_HOME cd $ORACLE_HOME/bin ./relink all # Following line should return no errors. grep -i err $ORACLE_HOME/install/relink.log dbstart $ORACLE_HOME
During the linking phase, you may see the following error.
Error in invoking target 'irman ioracle' of makefile '/u01/app/oracle/product/184.108.40.206/db_1/rdbms/lib/ins_rdbms.mk'
To fix it, run the following command as the "oracle" user, then click the "Retry" button.
cp $ORACLE_HOME/javavm/jdk/jdk6/lib/libjavavm12.a $ORACLE_HOME/lib/
During the database creation as part of the installation, or after when using the DBCA, you may get the following error.
Error while executing "/u01/app/oracle/product/220.127.116.11/db_1/rdbms/admin/dbmssml.sql". Refer to "/u01/app/oracle/cfgtoollogs/dbca/orcl/dbmssml0.log" for more details. Error in Process: /u01/app/oracle/product/18.104.22.168/db_1/perl/bin/perl
To fix it, follow the instructions to rebuild Perl as described towards the end of this post by Laurent Leturgez. You will have to redo the database creation.
