How To Uninstall Oracle Database 12c | Oracledbwr

oracle software deinstall

Starting with Oracle Database 12c Release 1 (12.1.0.2), the roothas.sh script replaces the roothas.pl script in the Oracle Grid Infrastructure home.

[oracle@Ram dbhome_1]$ cd deinstall/ [oracle@Ram deinstall]$ ls bootstrap_files.lst deinstall deinstall.xml readme.txt sshUserSetup.sh bootstrap.pl deinstall.pl jlib response utl

The most common method of running the deinstallation tool is to use the version installed in the Oracle home being removed.

The deinstallation tool determines the software configuration for the local Oracle home, and then provides default values at each prompt.

You can either accept the default value, or override it with a different value.

If the software in the Oracle_home is not running (for example, after an unsuccessful installation), then the deinstallation tool cannot determine the configuration, and you must provide all the configuration details either interactively or in a response file.

You must run the deinstallation tool from the same release to remove Oracle software. Do not run the deinstallation tool from a later release to remove Oracle software from an earlier release.

For example, do not run the deinstallation tool from the Oracle Database 12.2 installation media to remove Oracle software from an existing 11.2.0.4 Oracle home.
