Looping/Reading file contents not working

Hi,

I am doing something basic, but I am missing something. Im trying to read the contents of a file and taking those values and connecting to a database. However, it only connect to one (or reads in) value and then exists.

Here is what it looks like:

listname.txt
Code:
db1
db2
db3

Script:
Code:
dbcontent=/usr/home/listname.txt
echo "Enter userid" 
read USERID
echo "Enter passwd:"
stty -echo
read -s PASSWD
stty echo

while read dbname;
do
#Connect to SQLPlus
sqlplus -S  test/test123@$dbname << EOF
select ora_database_name from dual;
prompt my name is $USERID and my password is $PASSWD;
exit;
EOF
done < $dbcontent

It doesn't read all the lines (loop through) just exits after one run.
I am also trying to have it connect to each database (in the list).

echo(1B)					     SunOS/BSD Compatibility Package Commands						  echo(1B)

NAME
echo - echo arguments to standard output SYNOPSIS
/usr/ucb/echo [-n] [argument] DESCRIPTION
echo writes its arguments, separated by BLANKs and terminated by a NEWLINE, to the standard output. echo is useful for producing diagnostics in command files and for sending known data into a pipe, and for displaying the contents of envi- ronment variables. For example, you can use echo to determine how many subdirectories below the root directory (/) is your current directory, as follows: o echo your current-working-directory's full pathname o pipe the output through tr to translate the path's embedded slash-characters into space-characters o pipe that output through wc -w for a count of the names in your path. example% /usr/bin/echo "echo $PWD | tr '/' ' ' | wc -w" See tr(1) and wc(1) for their functionality. The shells csh(1), ksh(1), and sh(1), each have an echo built-in command, which, by default, will have precedence, and will be invoked if the user calls echo without a full pathname. /usr/ucb/echo and csh's echo() have an -n option, but do not understand back-slashed escape characters. sh's echo(), ksh's echo(), and /usr/bin/echo, on the other hand, understand the black-slashed escape characters, and ksh's echo() also understands a as the audible bell character; however, these commands do not have an -n option. OPTIONS
-n Do not add the NEWLINE to the output. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWscpu | +-----------------------------+-----------------------------+ SEE ALSO

The -n option is a transition aid for BSD applications, and may not be supported in future releases. SunOS 5.10 3 Aug 1994 echo(1B)
