How to deinstall Oracle Database software

Today i need to clean one Exadata from 12.1 software.
It is the rare operation, so i decided to record it.

The documentation says about runInstaller and deinstall .
And i decided to try runInstaller at first.

But no matter how i tried the runInstaller it always want response file or X Server:

[oracle@edbadm01 dbhome_1]$ ./oui/bin/runInstaller -deinstall -home /u01/app/oracle/product/12.1.0.2/dbhome_1
Starting Oracle Universal Installer...

Checking swap space: must be greater than 500 MB.   Actual 24575 MB    Passed
Checking monitor: must be configured to display at least 256 colors
    >>> Could not execute auto check for display colors using command /usr/bin/xdpyinfo. Check if the DISPLAY variable is set.    Failed <<<<

Some requirement checks failed. You must fulfill these requirements before

continuing with the installation,

Continue? (y/n) [n] y


>>> Ignoring required pre-requisite failures. Continuing...

DISPLAY not set. Please set the DISPLAY and try again.
Depending on the Unix Shell, you can use one of the following commands as examples to set the DISPLAY environment variable:
- For csh:              % setenv DISPLAY 192.168.1.128:0.0
- For sh, ksh and bash:     $ DISPLAY=192.168.1.128:0.0; export DISPLAY
Use the following command to see what shell is being used:
    echo $SHELL
Use the following command to view the current DISPLAY environment variable setting:
    echo $DISPLAY
- Make sure that client users are authorized to connect to the X Server.
To enable client users to access the X Server, open an xterm, dtterm or xconsole as the user that started the session and type the following command:
% xhost +
To test that the DISPLAY environment variable is set correctly, run a X11 based program that comes with the native operating system such as 'xclock':
    % <full path to xclock.. see below>
If you are not able to run xclock successfully, please refer to your PC-X Server or OS vendor for further assistance.
Typical path for xclock: /usr/X11R6/bin/xclock

This way i realized the runInstaller is not my way.

The another tool is deinstall.
Look, how it works:

[oracle@edbadm01 oracle]$ cd $OH/deinstall

[oracle@edbadm01 deinstall]$


Overall:
- it works in text terminal and don't use X Server
- it don't require parameter file
- it is simple: you should go to $OH/deinstall and run ./deinstall command 
- in the RAC environment it remove software from all RAC nodes !

I think it great tool !

[INS-35354] The system on which you are attempting to install Oracle RAC is not part of valid cluster

As docummentation says

Oracle Clusterware 12c supports Oracle Database 12c and Oracle Database 11g release 2 (11.2.0.3 and later)

But if you will try to install relatively old DB software (11.2.0.3 my case) on the 12.2 Grid then you will get "[INS-35354] The system on which you are attempting to install Oracle RAC is not part of valid cluster":








The reason is simple: new 12.2 oracle inventory hasn't NODE_NAME lines !
For example new 12.2 central inventory:



And central inventory with NODE_NAME limes:



What you should to do ?
SOLUTION:  Add NODE_NAME to the inventory manually 



$ /u01/app/12.2.0.1/grid/oui/bin/runInstaller -silent -ignoresysprereqs -updatenodelist ORACLE_HOME=/u01/app/12.2.0.1/grid "CLUSTER_NODES={ed03dbadm01,ed03dbadm02}" CRS=true
