Run the following command to confirm the memory size on a Linux server:

To verify the amount of memory and swap space, run the following command:
$ free -t
To verify the amount of space in the
/tmp

$ df -h /tmp
To display the amount of free disk space, execute this command:

To verify the OS version, enter this command:
$ cat /proc/version

Again, database server requirements vary quite a bit by OS and database version. You can download the specific
installation manual from the Documentation page of the Oracle web site (
www.oracle.com/documentation
).

Note
The OUI displays any deficiencies in Os software and hardware. running the installer is covered in step 6.
Step 3. Obtain the Oracle Installation Software
Usually, the easiest way to obtain the Oracle software is to download it from the Oracle web site. Navigate to the
software download page (
www.oracle.com/technology/software
), and download the Oracle database version that is
appropriate for the type of OS and hardware on which you want to install it (Linux, Solaris, Windows, and so on).
Step 4. Unzip the Files
Before you unzip the files, I recommend that you create a standard directory where you can place the Oracle
installation media. You should do this for a couple of reasons:
•
When you come back to a box a week, month, or year later, you'll want to be able to easily find
the installation media.
•
Standard directory structures help you organize and understand quickly what has or hasn't
been installed on the box.
