Question Korn Script to connect and query oracle database

I've been sent the following script to finish. It's supposed to connect to an oracle database, query it, and send an email if the query result value is one or more. Currently it isn't connecting properly, just giving the following error:

ERROR: ORA-01017: invalid username/password; logon denied SP2-0306: Invalid option. Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER|SYSASM}] where <logon> ::= <username>[/<password>][@<connect_identifier>] [edition=value] | / SP2-0306: Invalid option. Usage: CONN[ECT] [logon] [AS {SYSDBA|SYSOPER|SYSASM}] where <logon> ::= <username>[/<password>][@<connect_identifier>] [edition=value] | / SP2-0157: unable to CONNECT to ORACLE after 3 attempts, exiting SQL*Plus

First impressions (without detailed look).
Quote:
$DSS_USER/$DSS_PWD
Neither of these variables are set anywhere in the script. This could cause your login error.

EOF`
Should be two lines:
Quote:
EOF

Just pass the SQL credentials as below,

Code:
SQL=$(sqlplus -s $DSS_USER/$DSS_PWD <<EOF | grep -v "completed" | grep -v "^$" > $logfile



Also end should be,

Code:
EOF)
