Question setuid

I have a C wrapper programme which basically execute a shell script. The shell script has 700 as permission and oracle is owner of the shell script.
The C execuatble has 4711 permission so that means that it has setuid bit set and group and others can execute the C executable.
The reason why I am doing is, I don't want to give read access to my shell script to others and group and owner will have rw access to the script file.

When I execute my C execuatble as different user, it works great but I want some enhancement. When my script is being executed, it is executed as oracle user so every line in the script is executed as oracle user but there are certain things which I want to run as the real user not the effective user. e.g. my shell script calls sqlplus , so when sqlplus is being run , it is run under oracle user but what I want is , it should run under the name of real user.
Is there any easy way to do this ?

Thanks
Sanjay

script(1)						      General Commands Manual							 script(1)

NAME
script - Makes a transcript of terminal session SYNOPSIS
script [-a] [file] The script command makes a transcript of everything printed on your terminal. OPTIONS
Appends the transcript to file rather than writing it to file. OPERANDS
The name of an output file that will contain the transcript of the session. If this parameter is omitted, the file typescript is written. DESCRIPTION
The transcript is written to file, or appended to file if the -a option is given. If no file name is given, the transcript is saved in the file typescript. The script ends when the forked shell exits. This program is useful when you are using a CRT and want a hard-copy record of the dialog (for example, a technical writer might create an example of a working session this way). If you specify the -a option and the file does not exist, it is created. If you do not specify the -a option and the file exists, it is replaced. RESTRICTIONS
The script command requires a streams based terminal. In single user mode, streams may not be enabled. Under these circumstances, script will exit with no action. If you are the superuser and need to run this command in single user mode, use the following special instruc- tions. Enabling Streams If it is necessary to enable a streams environment in the single user mode, enter the command /sbin/init.d/streams. This command is avail- able to the superuser only. SEE ALSO
Commands: autopush(8), cat(1), echo(1), strsetup(8), tee(1) System Administration script(1)
