Oracle Database 12c Release Installation On Oracle Linux 7

Download Software

Download the Oracle software from OTN or MOS depending on your support status.

OTN: Oracle Database 12c Release 1 (12.1.0.2) Software (64-bit).
edelivery: Oracle Database 12c Release 1 (12.1.0.2) Software (64-bit)

This article has been updated for the 12.1.0.2 release, but the installation is essentially unchanged since 12.1.0.1. Any variations specific for 12.1.0.1 will be noted.

Depending on your version of VirtualBox and Oracle Linux, there may be some slight variation in how the screen shots look.
Unpack Files

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.

Hosts File

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       localhost.localdomain  localhost
192.168.0.210   ol7-121.localdomain    ol7-121

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.

Automatic Setup

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

It is probably worth doing a full update as well, but this is not strictly speaking necessary.

# yum update

Manual Setup

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.

/sbin/sysctl -p

Add the following lines to the “/etc/security/limits.conf” file.

oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 16384
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768

Install the following packages if they are not already present.

# From Public Yum or ULN
yum install binutils -y
yum install compat-libcap1 -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 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 libXi -y
yum install libXi.i686 -y
yum install make -y
yum install sysstat -y
yum install unixODBC -y
yum install unixODBC-devel -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.

Additional Setup

The following steps must be performed, whether you did the manual or automatic setup.

Set the password for the “oracle” user.

passwd oracle

Amend the “/etc/security/limits.d/90-nproc.conf” file as described below. See MOS Note [ID 1487773.1]

# Change this
* soft nproc 1024

# To this
* - nproc 16384

Set secure Linux to permissive by editing the “/etc/selinux/config” file, making sure the SELINUX flag is set as follows.

SELINUX=permissive

Once the change is complete, restart the server or run the following command.

# setenforce Permissive

If you have the Linux firewall enabled, you will need to disable or configure it, as shown here or here. To disable it, do the following.

# service iptables stop
# chkconfig iptables off

Create the directories in which the Oracle software will be installed.

mkdir -p /u01/app/oracle/product/12.1.0.2/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.

xhost +<machine-name>

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=ol6-121.localdomain
export ORACLE_UNQNAME=cdb1
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0.2/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

Installation

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.

./runInstaller

Post Installation

Edit the “/etc/oratab” file setting the restart flag for each instance to ‘Y’.

cdb1:/u01/app/oracle/product/12.1.0.2/db_1:Y

If Database Express 12c is not working, check the XMLDB HTTP port. If it is 0, set it to the port you want to use.

SQL> SELECT dbms_xdb_config.gethttpsport FROM dual;
GETHTTPSPORT
------------
5500

SQL> EXEC dbms_xdb_config.sethttpsport(5500);

PL/SQL procedure successfully completed.

Common Errors

  • “error code 35” : The machine name in the “/etc/hosts” file is not correct. It needs an entry for the loopback adapter (localhost) and the machine name. If you are using DNS for name resolution, you still need the loopback adapter reference in this file.
  • “error code 37” : The DNS not working properly. You may also get this error is the “/etc/hosts” file is not configured correctly.
  • “sqlplus: error while loading shared libraries: libclntsh.so.12.1” : The prerequisites have not been met. Work through them again. Specifically, make sure the “gcc” package has been installed.
  • Listener fails to start – Typically this is due to incorrect name resolution. Make sure the “/etc/hosts” and/or DNS is configured correctly.
  • Linking errors – Almost always due to missing prerequisites. Review the setup sections.

That is all. Any doubts I am available.

    My blog һas a lot of unique content І’ve either created myseⅼf or
    outѕourced but it seems a lot of it is popping
    it up aⅼl ⲟver the internet without
    my agreement. Do you know any methοⅾs to heⅼp prоtect
    against content from being ripped off? I’d definiteⅼy appreciate it.

    Your content is excellent but with images and
    videos, this blog could undeniably be one of the greatest
    in its niche. Superb blog!

  8. Hi, guys!
    Here there is a script that checks all prerequisites packages for an Oracle database and generates yum command for missing ones.
    It supports different versions of RedHat releases and Oracle database versions
    http://dbpilot.net/2018/01/31/installing-oracle-prerequisite-packages-for-oracle-database/

    The script: http://dbpilot.net/wp-content/uploads/2018/02/dbs_prepkgs.zip [ if link is broken then the script can be downloaded directly from the post]
    Issue dos2unix command on the script before you use the script.

    The dbs_prepkgs.sh is analog of oracle-rdbms-server-11gR2-preinstall.x86_64 and oracle-rdbms-server-12cR1-preinstall.x86_64 packages.

  9. I believe that іs оne of tһe most impоrtant info for me.
    Аnd i am happy studying your article. Howevеr want to remark ⲟn sߋmе normal tһings, The site
    style is ideal, the articles iѕ in poіnt of fact great : D.
