Defining the Password 
Select Expert mode to define the password for expert mode. Several of the steps necessary for this can usually only be performed by a user with root authorization (the UNIX administrator often has this authorization) and should be selected immediately after installation. SAPDBA will report when other users are authorized to perform this operation (platform-specific).
Creating the password
If you are setting the password for the first time, proceed as follows:
- In the Expert’s Password menu, select the function Set initial password for expert and enter the desired password twice in succession.
- SAPDBA stores the password in encoded form in directory
passwd
, file
passwd.dba
. If the directory (for example
/oracle/C11/passwd
) already exists, you will have to delete it first.
Changing the Password
To change the password, proceed as follows:
- Open a UNIX window parallel to the SAPDBA window. Log on as user
root
. Change to the ORACLE home directory (e.g.
/oracle/C11/
).
passwd
and assign file
passwd.dba
to owner
ora<sapsid>
(e.g.
orac11
).
- In the Expert’s Password menu, select the function Change password for expert. Enter the old password and then the new one twice in succession.
If you have forgotten the old password, delete directory
passwd
and create a new one as described above (you must be logged on as user
root
).
SAPDBA stores the password in encoded form in directory passwd, file passwd.dba. SAPDBA assigns the directory to user root.
On some operating system platforms, database user
ora<sapsid>
is not able to assign directories or files to user
root
. As a result, the password is not protected against unauthorized deletion. In such cases, SAPDBA issues a warning message with instructions for the administrator to change the owner and/or the access privileges.
