1. Hardware Requirements

The first thing we need to verify the hardware requirements for an Oracle 18c Release 3

— Check Physical RAM.
# grep MemTotal /proc/meminfo
We need at least 8192 MB of physical RAM. <----

— Check Swap Space.
# grep SwapTotal /proc/meminfo/*
RAM up to 1024MB then swap = 2 times the size of RAM
RAM between 2049MB and 8192MB then swap = equal to the size of RAM
RAM more than 8192MB then swap size = 0.75 times the size of RAM

We need at least 8192 MB of swap <----


-– Check space available in /tmp
# df -h /tmp/*
You need to have at least 2048 MB of space in the /tmp directory. <---

-– Check space for Oracle Software and pre-configured database.
# df -h

Space requirement for Oracle 18c Software:
Enterprise Edition 14G  <----

—- To determine whether the system architecture can run the software, enter the following command:

# grep "model name" /proc/cpuinfo

This command displays the processor type. Verify that the processor architecture matches the Oracle software release that you want to install. If you do not see the expected output, then you cannot install the software on this system.


2. Verify OS version

[oracle@rac1 product]$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.8 (Santiago)
[oracle@rac1 product]$


3. Unzip 18c Binaries

NOTE: You can't edit oracle home location while installation using OUI. It will pickup automatically ORACLE HOME location, where you have unzipped database binaries. Hence directly unzip in ORACLE HOME location and then start ./runInstaller

After unzip, it will NOT keep all files in single directory.

[oracle@rac1 ]cd /u02/app/oracle/product/18c
[oracle@rac1 18c]$ ls -ltr
total 4457672
-rw-r--r--. 1 oracle dba 4564649047 Jul 25 20:26 LINUX.X64_180000_db_home.zip
[oracle@rac1 18c]$

[oracle@rac1 18c]$ unzip LINUX.X64_180000_db_home.zip

[oracle@rac1 18c]$ ls -ltr

4. Set the DISPLAY Environment

Log into the oracle user. If you are using X emulation then set the DISPLAY environmental variable.

export DISPLAY=192.168.2.3:0.0;


5. Invoke ./runInstaller

Start the Oracle Universal Installer (OUI) by issuing the following command.

[oracle@rac1 ~]$ cd /u02/app/oracle/product/18c/
[oracle@rac1 18c]$ ./runInstaller         <-----
Launching Oracle Database Setup Wizard...

















6. Verify

[oracle@rac1 bin]$ export ORACLE_HOME=/u02/app/oracle/product/18c
[oracle@rac1 bin]$ ./sqlplus
