Oracle Database 12cR1 Installation on RHEL 6

Oracle Installation  of 12cR1 method’s are clearly indicated below. Each and every step is crucial to perform a error free setup. The following Installation is performed on a RHEL 6 64 Bit OS. The software Binaries vary from 32 and 64 Bit, be sure to download the correct software binaries.The files shown below are those for 64 Bit Linux OS on RHEL 6. Download only the first two files for installing Database Software.

linuxamd64_12c_database_1of2.zip
linuxamd64_12c_database_2of2.zip

Let’s get started with the Installation, there are two major parts of any Oracle Database Installation.

1. Operating System Settings
2. Oracle Database Installation

Let’s start with each one of them,

1. Operating System Settings

All settings indicated here are to be performed after RHEL 6 64 Bit OS Installations

• Ensure hostname and IP are set up properly, you will need to do the check same after Linux 64 Bit Installation.

[root@rhel1 ~]# more /etc/hosts
127.0.0.1 localhost
192.168.1.10 rhel1
192.168.1.11 rhel2
[root@rhel1 ~]# ifconfig -a | grep 192
 inet addr:192.168.1.12 Bcast:192.168.1.255 Mask:255.255.255.0
[root@rhel1 ~]# more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rhel1
GATEWAY=192.168.1.1

• Disable Firewall Settings : Firewall Settings can cause network issues while communicating with Applications.

[root@rhel1 ~]# service iptables save
[root@rhel1 ~]# service iptables stop
[root@rhel1 ~]# chkconfig iptables off
[root@rhel1 ~]# service network restart

Kernel Settings : Kernel Settings are of utmost importance to configure system wide configurable memory and allowable Port Ranges

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

• Ensure the /etc/sysctl.conf settings are setup fine, the following command should not throw any error’s

[root@rhel1 ~]# sysctl -p
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

• Create Users,Groups & Folder Structures

[root@rhel1 ~]# groupadd -g 54321 oinstall
[root@rhel1 ~]# groupadd -g 54322 dba
[root@rhel1 ~]# groupadd -g 54323 oper
[root@rhel1 ~]# useradd -u 54321 -g oinstall -G dba,oper oracle
[root@rhel1 ~]# passwd oracle
[root@rhel1 ~]# mkdir -p /u01/app/oracle/product/11.2.0/db_1
[root@rhel1 ~]# mkdir -p /u01/softwares
[root@rhel1 ~]# chown -R oracle:oinstall /u01
[root@rhel1 ~]# chmod -R 775 /u01

• Add the following Entries to /etc/security/limits.conf

more /etc/security/limits.conf
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft stack 10240
oracle hard stack 32768

• Change Settings in /etc/security/limits.d/90-nproc.conf and /etc/selinux/config as shown below

/etc/security/limits.d/90-nproc.conf

# Comment the following Line
* soft nproc 1024

# Include the following Line
* - nproc 16384

/etc/selinux/config
SELINUX=permissive

• Transfer the Oracle Database Media files linuxamd64_12c_database_1of2.zip and  linuxamd64_12c_database_1of2.zip to /u01/softwares

Mount the RHEL 6 64 bit CD or you can mount the ISO image

[root@rhel1 ~]# mkdir -p /media/rhel6iso
[root@rhel1 ~]# mount -o loop /u01/softwares/rhel_6.2_x86_64_disc_1.iso /media/rhel6iso
[root@rhel1 ~]# df -h
The df -h output shows you that the ISO media for RHEL6 64bit ISO has been mounter

The df -h output shows you that the ISO media for RHEL6 64bit ISO has been mounted

• Transfer ( using sftp, ftp in bin mode,scp,filezilla, etc.. ) Oracle Database Media files p10404530_112030_Linux-x86-64_1of7.zip and p10404530_112030_Linux-x86-64_2of7.zip to /u01/softwares. Mount the RHEL 6 64 bit CD or you can mount the ISO image

[root@rhel1 ~]# mkdir -p /media/rhel6iso
[root@rhel1 ~]# mount -o loop /u01/softwares/rhel_6.2_x86_64_disc_1.iso /media/rhel6iso
[root@rhel1 ~]# df -h
----------The df -h output shows you that the ISO media for RHEL6 64bit ISO has been mounter

2. Oracle Database Installation

• Login as Oracle User and set the Environment Variables in  /home/oracle/.bash_profile

-- Add the following Entries to .bash_profile
# Oracle Settings
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=ol6-121.localdomain
export ORACLE_UNQNAME=cdb12c
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1
export ORACLE_SID=cdb12c
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

to
CV_ASSUME_DISTID=OEL6
More information see metalink [ID 1304727.1]

•  Create Database using dbca, use the GUI to set up all parameters for Database Creation, the Listener should be running at this time otherwise use netca to create the Listener.

oracle@rhel1 ]# cd /u01/softwares/database
[oracle@rhel1 database]# ./runInstaller
--
-- Complete the Installation and run the root scripts at the end
--
[root@rhel1 ~]# /u01/app/oraInventory/orainstRoot.sh
[root@rhel1 ~]# /u01/app/oracle/product/11.2.0/db_1/root.sh

• In case you are directlly working on the server Set “xhost +” as root user and start working from oracle user.
• In case you are working from a Ubuntu client, login to oracle as “ssh -X oracle@192.168.1.10“
• In case you are connecting to oracle user from a Windows PC to the Serve through putty, install Xmanager Software and export DISPLAY=<IP_of _your_PC>:0.0 and start XManager in the Start Tray

• Start Installation of Oracle with software only option ( You will need to run a couple of scripts as root user at the End of the Installation )

That brings to the End of Oracle Software Installation & Database Creation.
