Remove Oracle / Uninstall

I post this topics for people who want to learn how to remove Oracle For Window/Linux 


Windows :

Its easy common steps you have to follow :

  • Uninstall all Oracle components using the Oracle Universal Installer (OUI).
  • Run regedit.exe and delete the HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE key. This contains registry entires for all Oracle products.
  • Delete any references to Oracle services left behind in the following part of the registry (HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Services/Ora*). It should be pretty obvious which ones relate to Oracle.
  • Reboot your machine.
  • Delete the “C:\Oracle” directory, or whatever directory is your ORACLE_BASE.
  • Delete the “C:\Program Files\Oracle” directory.
  • Empty the contents of your “C:\temp” directory.
  • Empty your recycle bin.

Unix :

  • Uninstall all Oracle components using the Oracle Universal Installer (OUI).
  • Stop All Oracle Process .

lsnrctl stop
emctl stop dbconsole
emctl stop agent.

  • Delete the files and directories below the $ORACLE_HOME.
# cd $ORACLE_HOME
# rm -Rf *
  •  delete directories below the $ORACLE_BASE.

 # cd $ORACLE_BASE
# rm -Rf admin

  •  Delete the /etc/oratab file

Done .
