Instlling Oracle on top of itself [message #611437]

Situation:
We have lost all the passwords to all of our Oracle accounts (including sys and system). Can we install the same version of Oracle on top of the existing installation to reset the ID's and passwords of the accounts without destroying the data that's currently there? I've already created a thread about trying to reset the passwords of the sys or system account as well as looking for some kind of back door to gain access. I've had no success with the suggestions posted by forum members (I do appreciate the effort/suggestions). I do have an RMAN backup, but that won't help me without the password for the sys and system accounts. I don't have a tape backup. Will installing Oracle on top of itself delete all of the instance information? Is there a recovery option within the installation to reset the passwords? What options do I have?

I was also thinking about installing another instance along side the existing instance and transferring the data. Is this possible? I know in SQL you can export the db and basically take it to another server with the same version on it and import the db. Would this be my final solution or is there a way of getting around the sys and system accounts?

Just connect "/ as sysdba" and change SYS and SYSTEM passwords.

I've already tried this with my OS account as well as a sys and system local OS account. On all three accounts I get "Insufficient Privileges" error.

Just to verify:

C:documents and settings\<userid>\> sqlplus / as sysdba

All id's are in the ora_db group and all are local admins.

I'm assuming you are referring to the person that installed the software?

There is a huge difference between

sqlplus / as sysdba

and

sqlplus "/ as sysdba"

of course.

Copy and paste the exact result of the following:

set ORACLE_SID=[Your SID]
sqlplus "/ as sysdba"

I'm unable to copy and paste due to security reasons, but here's what I get:

C:\documents and settings\<mydomainid>\ splplus "/as sysdba"
enter password: <I enter my domain password>

ORA-01031: insufficient privileges

FYI -- I'm a domain admin as well as a member of the ora_db group.

I tried that as well -- same ORA-01031 error.

This is a local account by the name of sys and the account is a local admin and part of the ora_db group.

What is true? Both can't.
No one can help you with false information.
I give up.
Good luck.

Please re-read the post -- one is a domain id and the other is a local account. I've tried both.

For me, too.

IF you are doing it with the User that has installed Oracle, and who is in the local ORA_DBA group that was created when Oracle was installed, then it will work.

Is there a local ORA_DBA group on the machine?
Do the Oracle files belong to a member of that group?
Have you tried all that with that member of that group?

Resolution: switched the sql_authentication_services= backt to (NTS) from (NONE) in sqlnet.ora
added multiple admin groups to the Oracle Administrators Assistant for Windows snap-in
restarted listener and db service and we were able to login "/as sysdab"

thanks for the help
