Oracle Express Edition passwords?

If so:
from a command prompt:
sqlplus / as sysdba

That connects you as the SYS user.  From here you can change whatever users password you want.

For example SYSTEM:
SQL> password system

Firstly thanks for prompt response

yes it is currently \oracle\product\10.2.0\ version

This is a legacy install and I have no Oracle experience.

So to confirm from the command prompt
Type sqlplus / as sysdba

Type sysdba> password xxxxx

>>Type sqlplus / as sysdba


That should get you to a SQL> prompt

Then you type:
password some_user

You will be prompted for the new password.

Note: If applications connect with the user, they might have the user password stored outside of the database and changing the password can cause the apps to stop working.

You need to make sure you are logged into the machine with a user that is a member of the ORA_DBA group.

Do you have more than one Oracle product installed on this machine?

Sorry for delay in replying, no other Oracle products are installed

Hi I was eventually able to reset the system password here was the solution I found on here

Basically, You need to do 2 things. First, add your userid into the windows OS group called ora_dba. Second, go into the directory where Oracle is installed, into the network/admin directory and edit the sqlnet.ora file with notepad. Change (NONE) to (NTS) for the sqlnet_authentication and save the file.

 Then you can login to sqlplus “/as sysdba”
For some reason, the e1 local database installation decided to turn off OS authentication

Thanks for all your help :)

Yes.  I forgot that piece on Windows.  Oracle and Windows really do not get along real well.
