解决连接Oracle报ORA-01034和ORA-27101的错误

我本机安装的数据库版本是Oracle 11G R2,今天连接数据库时,报如下错误:

ORA-01034 - Oracle not available

ORA-27101 - shared memory realm does not exist

经过总结,,使用如下方法解决比较好:

1、首先看一下 ORACLE_BASE\ORACLE_HOME\DATABASE 下面的 ORADIM.LOG 文件
C:\app\Administrator\product\11.2.0\dbhome_1\database:

看日志才发现原来报的下面的错误!!

ORA-00119: invalid specification for system parameter LOCAL_LISTENER

ORA-00132: syntax error or unresolved network name 'LISTENER_ORCL'

2、进过查找该错误,发现是tnsnames.ora文件中少了如下语句的原因

LISTENER_ORCL =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

添加后,重启数据库实例服务:

再次使用SQLPLUS、TOAD连接,好了,哈哈!
