Migrating from Oracle Forms 6i to Oracle Forms 10g

 I am unable to execute a script from the Forms built in HOST command. An example is I built a script with the following:

viewteps.com:

/usr/bin/ls -l > dir.txt

The HOST COMMAND is:

HOST('/apps/teps/forms/viewteps.com');

I added FORM_SUCCESS with the following message when it fails:

message(to_char(dbms_error_code)||': '||dbms_error_text||','||to_char(message_code)||': '||message_text);

I receive the following error message when I execute the HOST COMMAND:

ORA-24309 already connected to a server 1017: Invalid username/password; logon denied I am wondering what files I should be looking at to see why I am receiving this message.
