On current releases one should just chown the $ORACLE_HOME/bin/oratclsh to oracle (or whoever the install userid is); on Linux and Solaris that will also remove the suid bit. When I pressed them as to whether or not they would release patches and information to users who already have 8.0.5 installed they said they had no mechanism to do that. In other words, YOYO. (They could learn something about patch releases and access from their good buddies at Sun). So if you've installed Oracle's Intelligent Agent or aren't sure if it's installed then check your oratclsh and fix that bit. The only systems I've had experience on are 8.0.5 for Solaris and Linux but I'd check any 8.x release on any platform if it were mine. John Ritchie Systems Software Analyst Oregon University System
