Well, the C program may not work.
Check this out:
Code:
$ cat test.c
#include <stdio.h> 
main(){ system(" sleep 1234 "); } 

$ gcc -o test1 test.c
$ ./test1 &
[1] 7718
$ ps -ef
< snipped for brevity >
me      7718  7241  0 00:19 pts/1    00:00:00 ./test1
me      7719  7718  0 00:19 pts/1    00:00:00 sleep 1234
me      7720  7241  0 00:20 pts/1    00:00:00 ps -ef
$

Will this aplication prompt you for a password if you don't supply one on the command line (like sqlplus)?
In that case, you might be able to use a shell script:
Code:
#!/bin/sh
/path/to/CONCSUB <<EoF
USERNAME/PASSWORD@DB
command
another command
EoF

This may or may not work though. Either way, though, make sure you lock down permissions on the file so one one but you can read it. The commands passwords will be left in pleain text in the script and also in the compiled C program.

       --watch
	   Continuously process password requests.

       --wall
	   Forward password requests to wall(1) instead of querying the user on the calling TTY.

       --plymouth
	   Ask question with plymouth(8) instead of querying the user on the calling TTY.

       --console
	   Ask question on /dev/console instead of querying the user on the calling TTY.

       -h, --help
