Home -> Community -> Mailing Lists -> Oracle-L -> RE: Removing Older version of Oracle on NT Machine
Hi All,
I'll add some points about NT backup to this list of steps...
>>>>>
1.a. Backup all drives, sample command could be
ntbackup backup c:\ d:\ /B /V /L " D:\FULLBACKUP.LOG" /D "FULL SYSTEM BACKUP" /B would backup registry.
1.b. Create one repair disk by typing command rdisk at command prompt. This should always be created as part of complete backup. But you need to create/update them only when there is any changes in system configuration/ softwares.
1.c. Optionally you can take export backup of Registry. Type regedit on
command prompt and select Registry->Export Registry file.
>>>>>>>
Of course Above steps I would execute as first step......
Next while removing services I had faced problems recently using ORADIM(xx).
The command should be
ORADIM80 -DELETE -SRVC <service_name>
or
ORADIM80 -DELETE -SID <sid_name>
The executable name for Oracle 8i is ORADIM. So while deleting services through ORADIM80, it was not getting deleted.
Alternatively, you can delete it from Registry, as follows...
2. Goto HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and remove all keys under here that begin with ORACLE.
Now some final clarification about Deleting registry entries of Oracle...
3.a. Start the registry at the MS-DOS command prompt: C:\> REGEDIT
3.b. Go to HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE and delete this ORACLE key.
3.c. Go to HKEY_LOCAL_MACHINE\SOFTWARE\ODBC and expand all subkeys and remove all keys under here which are related with the "Oracle ODBC Driver"
3.d. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services and remove all keys under here that begin with ORACLE.
3.e. Go to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\...
\Application and remove all keys under here that begin with ORACLE.
3.f. Close the registry.
4. Environment Cleanup can be done by right clicking "My Computer" icon on your desktop. Then Choose Properties->Environment. Here you can delete/set PATH variable and other variables(e.g. ORACLE_SID,ORACLE_HOME etc.) Just note that these variables are derived from this location if not found in Registry and take precedence over Registry entries( Similar to Unix :-).
I hope we have compiled the complete steps, anything still left... Feel free to add ;-)
Cheers,
Rajesh
