Userid Passwd from a plsql code to shell script

I submit a job using dbms_scheduler which invokes a shell script that connects to database.
I pass the userid and password to shell script as arguments via the job.
But when I do ps - ef ... I can see the username and password being displayed on screen...

I have two questions:
1. What should I do to avoid the display of password by executing ps -ef .
2. As I am already connected to the database, can I directly send the user id and password to shell without specifying it manually.. i.e. Currently I send the user id and password hardcoded in my job arguments... If the password changes in future, I need to change my code too.. Is there a way where I do not have to send the hard coded user id and password from plsql.

I usually have a config file stored somewhere securely on the server with username/password/database combinations to be used for scripts. I can have a common function to extract it in your profile script and every other script can retrieve them as needed - nothing shows up on the command lines.

Of course if you dont/cant secure the file properly, there's not much point.

You mean to say that there is no way we can find out the password of the current connected session by querying any dictionary view..

No, definitely not. You can get a hashed version of it (http://www.lifeaftercoffee.com/2005/08/23/oracle-password-hacks/), but that is not enough to re-connect with.
