How do you do this for an export cron job ?
Thanks

The 'hide.c' program can be implemented and compiled to prevent parameters from appearing to ps. I believe it still works properly on most flavors of unix.
For the "Perl for Oracle DBA's" book we wrote one utililty that I had wanted for some time, a password database.
For jobs that I plan to run regularly from cron, I use the password daemon pwd.pl and retrieve the passwords across the network ( encrypted with MD5 ).
If the job is a Perl script ( fairly likely around here ) the password can't appear to PS, as no password is ever used on the command line.
It's handy for command line stuff as well, as I only need rights to access the password database via the password daemon. I don't have to know the database passwords to login to the account.
e.g. sqlplus system/$(pwc.pl -instance dv01 -username jkstill)@dv01
This is the single most useful utility we put in that book IMO.

on UNIX you could use a secret hidden file with appropriate permissions where each line has the format ORACLE_SID:USER:password
then use awk to parse the file for the line with the correct $ORACLE_SID and $USER, and set an environment variable to the password string. Then your scripts could use that variable with sqlplus instead of the hardcoded password.
in ksh it could look something like this: export password=\ `awk -F: '$1 == "sid" && $2 == "dbimpl" {print $3}' mySecretHiddenFile`
be warned that if you call sqlplus like this in your scripts: sqlplus dbimpl/${password} @SQLscript.sql someone could still see the Oracle password with a sneaky ps command while your script is running.
a very similar approach could be taken with perl if awk isn't your cup of tea.

I have been tasked to write a script to run SQL. I don't want a password field to be shown in the script. Does someone have run into this and have a better idea? For example, I have following line in my script.
Sqlplus dbimpl/password @SQLscript.sql
Also, from command line we go through following steps to shutdown database, how do I code these steps in the script?
$svrmgrl SVRMGRL>connect internal SVRMGRL>shutdown
Thanks in advance, David
