You can use ShellGuard (www.fstha.com):

$ uname -a
SunOS ess038 5.8 Generic_117350-02 sun4u sparc SUNW,Ultra-60 $ cat script.sh
#!/usr/bin/ksh
sqlplus -S << !
test/test
set pages 0 feed off
select sysdate from dual;
!
$ fstsg script.sh
ShellGuard 0.2
Foundation Software Tools
http://www.fstha.com
Using: /usr/local/bin/gcc
Compiling /app/oracle/scripts/fstsg.0.2/script.sh.x $ ./script.sh.x
11-OCT-06
$ strings script.sh.x | grep test
$

Be aware that on some systems the *shell code* or some part of it is visible via the ps command while the script is running ... (not sure if that was the case for shc or Shell Guard).
