		<description><![CDATA[客户端报 “ORA-27101: shared memory realm does not exist SVR4 Error: 2: No such file or directory”。 查了半天，竟然是因为服务器上这次起Oracle用的路径和上次不一样。虽然是link到同一目录的，但由于和 lisnter 里配置的不一致，所以导致连不上。重新改过 ORACLE_HOME 之后解决。 顺便记一下启动Oracle的方法： cd $ORACLE_HOME/bin ./sqlplus &#8216;/ as sysdba&#8217; SQL&#62;startup SQL&#62;quit ./lsnrctl start]]></description>
