Installation of Oracle Database 12 c r1 on RHEL 6.1

This post shows Installation of Oracle database 12c r1 (12.1.0.1) on Red Hat Linux 6.1 64 bit OS .
For this installation I have installed RHEL 6.1 selecting all the packages available .

I will install Oracle RDBMS in  /orabin mount point under the path /orabin/app/oracle/product/12.0.1 . This path is nothing but the ORACLE HOME. For ORACLE BASE the path will be /orabin/app/oracle/product

We will create OINSTALL group which will install the software and DBA which can create the database .

Let us make the path in OS

[root@linux6 orabin]# mkdir -p /orabin/app/oracle/product/12.0.1
[root@linux6 orabin]# groupadd oinstall
[root@linux6 orabin]# groupadd dba
[root@linux6 orabin]# useradd -g oinstall -G dba -d /home/oracle -m oracle
[root@linux6 orabin]# passwd oracle
Changing password for user oracle.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: all authentication tokens updated successfully.

[root@linux6 orabin]# chown -R oracle:oinstall /orabin
[root@linux6 orabin]# chown -R oracle:dba /data1 /data2

Oracle RDBMS software has been kept in /opt hence set permission to /opt so that we can unzip the RDBMS binaries .

[root@linux6 orabin]# chmod -R 777 /opt

after you finish unzip of files you will get single directory as "database" .

Now we will set the bash profile for our installation.

[root@linux6 opt]# su - oracle
[oracle@linux6 ~]$ vi .bash_profile

export ORACLE_HOME=/orabin/app/oracle/product/12.0.1
export ORACLE_SID=orcl
export PATH=$PATH:$HOME/bin
export PATH=$ORACLE_HOME/bin:$PATH:.

After setting the bash profile we can start the installation of Oracle Database.

OUI is GUI based installar hence for Allowing normal user to invoke GUI, run following command as root user.

[root@linux1 ~]# xhost +

In following Snapshots installer did not give pre-requisite check window but my installation got succeeded .  

Now its time to invoke OUI i.e runInstallar

[oracle@linux1 database]$ ./runInstallar
