Is this a new database? It's possible that the "root.sh" script wasn't run... You may want to check the permissions on ${ORACLE_HOME}/bin/oracle to see if it is setuid (it should be). Also, I'd do a "ps -ef|grep ora_" to see if the processes are indeed running as the "oracle" user. -- James ---------------------------------------------------------------------- James J.
