不知道什么原因：之前刚刚是好的 后来登陆pl/sql 本地数据库时，服务都已启动了 提示：ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist 我还在网上查了下，已经确定不是ORACLE_SID和ORACLE_HOME 的问题了，检查过没改变，并且昨天还用的好好的，今天突然就出了这个问题，不可能是修改了ORACLE_SID和ORACLE_HOME。
不过我也试了下： 1. cmd 命令下： set ORACLE_SID=orcl;之后在重新启动服务 还是不行；
2. (1). 在运行中输入cmd，输入sqlplus /nolog,回车， 这时出现了SQL>；
(2).输入connect / as sysdba;回车；提示：
ORACLE 例程已经启动。
