At first sight your code looks correct (save for some minor things which shouldn't matter here), so try to isolate the problem. What does

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

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

do? Does it still go only once through the loop, then probably something with the input file is wrong (unprintable characters or the like). Is the problem gone, then something with the sqlplus-command is responsible. Either way you know more then than you know now.

I hope this helps.

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)
