(C2 audit requirement)By default this information is written to $ORACLE_HOME/rdbms/audit.Diagnosis:On UNIX:1) Ensure the directory $ORACLE_HOME/rdbms/audit or the directory specified by the init.ora exists, is writable by the oracle software owner and that the disk is not full. 2) Check $ORACLE_HOME/bin/oracle has permission of 6755. If not, then correct the permissions by executing this from the $ORACLE_HOME/bin directory: chmod 6755 oracle 执行完后，效果如下：启动数据库报错信息RROR:ORA-12545: Connect failed because target host or object does not existERROR:ORA-12541: TNS:no listenerERROR:ORA-12514: TNS:listener does not currently know of service requested in connectdescriptorlccxyx $ lsnrctlLSNRCTL for Linux: Version 10.2.0.1.0 - Production on 18-DEC-2010 07:01:51Copyright (c) 1991, 2005, Oracle.
