I had a 9.0.1 on a win2003 server recently and today I tried to install
10.1.0 on that machine.

Somehow deinstallation of 9.0.1 which was oin that machine before
did not work smoothly. I tried to remove registry entries but
could not remove all for some reason.

During installation of 10g I was told that an instance (ORCL) was already
there and I should use another name. Anyway, to make it short, the 10g
installation failed. I have an empty pfile directory in admin\orcl\pfile
and would like to start over the 10g installation without
having to reinstall the whole OS.

Any clues how to totally get rid of any traces of Orcale and get a clean
environment to start a fresh installation?

Can't speak to the versions you have, but with 8i on Windows 2000, we have
found it much faster to rebuild the server (OS, etc.) from scratch than to
try to eliminate all traces of 8i.

Try these instructions, they are for Windows NT but should work on Windows
2000 & 2003...
Removing Components on Windows NT
To remove all Oracle components from a computer on Windows NT:


----------------------------------------------------------------------------
WARNING:
These instructions remove all Oracle components, services, and registry
entries from your computer. In addition, any database files under
ORACLE_BASE\ORADATA\DB_NAME are also removed. Exercise extreme care when
removing registry entries. Removing incorrect entries can break your system.


----------------------------------------------------------------------------


Ensure you are logged in as a user with Administrator privileges.

Stop all Oracle services (if any are running):

Choose Start > Settings > Control Panel > Services.

If any Oracle services (their names begin with Oracle) exist and have the
status Started, select the service and click Stop.

Click Close to exit the Services window.

Start the registry at the MS-DOS command prompt:

C:\> REGEDT32

Go to HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE.

Delete the ORACLE key.

Delete any Oracle key under HKEY_LOCAL_MACHINE\SOFTWARE\ODBC.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es and remove all
keys under here that begin with ORACLE.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es
\EventLog\Application, and remove all keys under here that begin with
ORACLE.

Close the registry.

Go to Start > Control Panel > System > Environment tab.

Click on the system variable path and modify the Path variable.

If JRE was installed by Oracle, remove the %ORACLE_HOME%\BIN path and the
JRE path. For example, you may see a path similar to this one:

C:\ORACLE\ORA81\BIN;G:\PROGRAM FILES\ORACLE\JRE\1.1.7\BIN

Exit the Control Panel.

Go to SYSTEM_DRIVE:\WINNT\PROFILES\ALL USERS\START MENU\PROGRAMS.

Delete the following icons:

Oracle - HOME_NAME

Oracle Installation Products

where HOME_NAME is the previous Oracle home name.

Delete SYSTEM_DRIVE:\Program Files\Oracle.

Delete all ORACLE_BASE directories on your hard drive.

Reboot your computer.

Try the following steps:
a.. Shutdown and drop the database using SQL * plus
$sqlplus /nolog
SQL>connect / as sysdba
SQL>shutdown immediate
SQL>exit

a.. remove following directories/files:
app/oracle_admin/$ORACLE_SID
oradata/$ORACLE_SID
$ORACLE_HOME/dbs/init$ORACLE_SID.ora
$ORACLE_HOME/dbs/lk$ORACLE_SID
$ORACLE_HOME/dbs/orapw$ORACLE_SIDGood Luck!Jim Cheng

Bzzt! That shuts down the db, but doesn't DROP it.

Bzzt! That only removes some specific db related files, not Oracle
itself. And it removes them from a Unix system, not the Window system
the OP asked about. And it assumes whatever files were placed in a
directory 'app/oracle_admin ...' which is certainly not a given but
simply local standard.

There is a lengthy paper on MetaLink about how to wipe Oracle from a
Windows system (running de-install from the Oracle Universal Installer
doesn't even begin to get the job done). As others have pointed out,
it boils down to
1 - stop all Ora* services
2 - delete the registry key HKLM\software\oracle
3 - delete the Oracle registry keys from HKLM\software\odbc
4 - delete the Oracle registry keys from HKLM\Current Control
Set\services
5 - delete all Oracle directories from your hard drive. You may need
to stop the service Distributed Transaction Coordinator to release
locks on one of the dlls -- I belive it's CORE32.dll or something
similar.
6 - remove oracle references from you PATH.

This may still leave some obscure references deep in the guts of the
registry, but I've never found that to be a problem, and I have
followed the above procedure dozens of times.

1. fdisk
2. clean install of w2k3 svr

had to do this last night when I botched an upgrade of the w2k HAL
from uni to multi processor. A bearded old guy appeared and said "you
have chosen poorly" and screams arose in the server room.

THAT is how you know that your backups work - when the entire storage
configuration was lost and the partitions on the RAID vols are no
longer there.

after that it was smooth sailing for the rest of the 8.1.7 to 9.2
upgrade.

Thanks for all the tips.
At present I have another woe:

I followed the instructions suggested but when I want to reinstall
(8.1.7 in this case on XP) I have one deinstallation pending (8.1.7
which I chose before on my fruitless attempt to deinstall using
the "de"installer) and the other products are not getting installed since the
installer "thinks" they are already installed.

5 years of working with Oracle, mainly on Solaris and Linux, I've had
numerous issues with deinstalling orasw.
