Create Directory for Oracle Home

We would like to install the software in the directory /opt/oracle/product/12.1.0/db_2.

mkdir -p /opt/oracle/product/12.1.0/db_2
hosts File

If your /etc/hosts file does not contain the name of the host, add it

cat /etc/hosts
127.0.0.1   localhost localhost.localdomain
192.168.1.75  orcl
limits.conf

If there is an earlier version of Oracle database running, there will not be any changes to limits.conf. But for referrence, I've put the file below.

cat /etc/security/limits.conf
oracle               soft    nproc   2047
oracle               hard    nproc   16384
oracle               soft    nofile  4096
oracle               hard    nofile  65536
oracle               soft    stack   10240
#oracle              hard    stack   32768
Download the Oracle 12c R1 Database software

Download the software from Oracle Technology Network. The database software comes in two .zip files as below :

Extract the files

Unzip the files using unzip command.

$ unzip linuxamd64_12102_database_1of2.zip
$ unzip linuxamd64_12102_database_2of2.zip

As a result, a directory by name database will be created and has the following content.

$ cd database/

$ ls -l
