How to recover the Oracle 7 system password under HP-Unix

Asked by: mnasman

Hello,

  I got a new job, with oracle 7 under old hp-unix system, they have an old application developed with oracle forms (3 i think) and based on oracle 7, the system running since around 12 years,and I  talked with guy who admin the server and the application, and I got few users/password from him for the Root password, and an user to backup the database(not an oracle user), and the oracle user for the application

now the problem that admin(who should be), don't know the oracle system password, he's only export the data from the application user, and run/shutdown the server. and BELEIVE IT OR NOT, No one there know the password of oracle system user, or any dba user :-o.

  So, if I have the root password, can I get the oracle system password?, or change it

Regards,
Mohammed

Can you:

   su - oracle

then, connect:

   svrmgrl> connect internal

If you can get in this way, you should be able to change any user:

   svrmgrl> alter user system identified by password;

Oracle 7.x stuff is archived way back in my brain, so maybe rusty...

And if that doesn't work... have you tried the "default" system password:  manager

 

by: markgeerPosted on 2007-08-29 at 11:54:23ID: 19794209

The suggestions from joebednarz look good to me.  One other default password to try in Oracle7 is the SYS password, which was: "change_on_install".

 

by: vishal68Posted on 2007-08-29 at 23:54:12ID: 19797947

depending on oracle 7 version, svrmgrl may not work. in that case use
sqldba lmode=y instead of svrmgrl.

rest will be as joebednarz has suggested

I recommend that you preserve the the existing encrypted password, should you discover the password is hardcoded in decade-old batch scripts. With the existing string one can alter the account back as ALTER USER xx IDENTIFIED BY VALUES "string".
15:09:57 SYS @WSMISD > select username, password from dba_users where username = 'SYSTEM';

USERNAME                       PASSWORD
------------------------------ ------------------------------
SYSTEM                         4CC149XXXXA32A8A <not my real string, of course>

On the other hand, your SYS and SYSTEM accounts are likely to be identified externally,  The bin folder will have a utility named orapwd, documented in many sites such as: http://www.orafaq.com/search/orapwd
