The "sushc" executable can either be set up such that either any user can be the "target" user, or only one user can be. For the former then it needs to be owned by "root", otherwise by the specified user.
Creating the "sushc" executeable involves:
cc sushc.c -Wall -osushc
chmod ug+s sushc
chown root:root sushc
chown oracle:dba sushc
cp sushc /usr/bin
cp sushc /home/oracle/bin
