Oracle Database Pre-Built

12.1.0.2 Database on

VirtualBox

Step by step screenshots showing the installation of Virtual box and configuring

pre-built Oracle Database 12.1.0.2 (including in-memory option). A quick way to

get started on Oracle Database 12c. This is a very easy setup, though many do

not know how easy it is to get started and playing with Oracle Database 12c on

Linux platform using VirtualBox. Hopefully these screens will convince you to

download and setup, and start playing with Database 12c and its various

options. There are not many complicated steps to get this done, the screens are

pretty much self-explanatory!

First download and Install VirtualBox. Always download the latest and greatest

version.

Then download the pre-built Oracle Database 12c (12.1.0.2) Virtual Host Image

file, and import to VirtualBox.

By default the VM is configured to use only 1GB RAM. This is very low. If your

computer has memory, 4G or more for the VM would be really beneficial.

Will show screens on Starting the Virtual Host and using the database as well.

Good Luck learning Oracle Database 12c!

Change location of Disk Image if required. Adjust memory as well, or you can

adjust later.

Click Import.

Once import completes, the Machine appears on VirtualBox.

The disks are also visible

On the right side, details of the machine is displayed.

Let us increase the memory of the machine, if your laptop/desktop has enough

free memory. Make any other adjustments as you find suitable. All defaults work

just fine.

Click settings.

If you want any OS folder to be visible on the VM machine, add it to the Shared

Folder. For example, if you have downloaded software or you want to copy files

to the VM, it is easy to create shared folder.

Here is an example screen from Optimizer class:

The database is started automatically.

[oracle@localhost Desktop]$ env |grep ORACLE

ORACLE_SID=cdb1

ORACLE_HOME=/home/oracle/app/oracle/product/12.1.0/dbhome_1

[oracle@localhost Desktop]$ ps -ef |grep pmon

oracle 1634 1 0 22:05 ? 00:00:00 ora_pmon_cdb1

The shared folder added is also visible and mounted as /media/sf_Oracle12c.

Thus files on your local machine folder are visible in the VM.

Contents of readme.txt file is displayed when you login…

The database name running is “cdb1”. The TWO_TASK variable is set to “orcl”.

So, your “sqlplus / sysdba” fails. Unset the TWO_TASK variable to login as sysdba.
