Re: Uninstall

cd $ORACLE_BINARY_DIRECTORY

rm -rf *

There is also a removeal utility that comes with the universal installer utility from oracle

runInstaller

Its X GUI and point and click. No batch version.

Re: Uninstall

Well, if you want to use your database (data) in future, you need to export and back it up. If you are all done with those step, you can safely remove your $ORACLE_HOME files and your configuration files manually. There is no "uninstall" program as such in Oracle.

Re: Uninstall

Hi Mike,

the easiest thing of course would be to shutdown oracle and make a full backup of oracle including files. The other depends on, whether you ever want to run oracle or at least the current version on this machine again. If not, the rm of SEP would be the best. As far as I remember the runInstaller leaves the inventory files behind. Have a look for oracle files with
find / -user oracle -print
to see, where oracle has spreaded its files.
Oracle also leaves a few files in /usr/local and /etc

have fun being here,

Re: Uninstall

Hi Mike,

what are you looking for?
runInstaller is in $oh/bin or it was not installed. You then can start an installation and when in the main menu uninstall products.

Re: Uninstall

Hi,

In fact you use the Oracle Universal Installer for both installing and de-installing oracle software.

The installer has a process that keeps an inventory of what products have been installed.

So it is important that you remove your oracle products using this tools so as to keep your repository up-to-date.
See metalink note: 74182.1

The following is a brief outline of the procedure:

1- Verify dependencies
2- Stop the instance
3- De-install using OUI
4- Remove configuration information from OID
5- Remove Oracle Home
6- Update shared files
7- Cleanup OUI files (Optional)

see note: 218277.1 for more details.

regards

Re: Uninstall

Thanks, again I was just going to say that the runinstaller in $ORACLE_HOME isn't there, and the $ORACLE_BINARY_DIRECTORY wasn't set. So, I will check Metalink.

Re: Uninstall

Hi Mike,

the directory is $ORACLE_HOME/bin. I think $ORACLE_BINARY_DIRECTORY was meant by that.

greetings,

Re: Uninstall

Thanks again everyone,

I'm new at this DBA stuff, now I'm on the right page with the runInstaller.
