ORA-27101: shared memory realm does not exist 问题解决办法

我今天开机发现Oracle的service、listener两个服务都正常启动但是sqlplus登陆提示:

ERROR:

ORA-01034: ORACLE not available

ORA-27101: shared memory realm does notexist

网上查找解决这个问题的办法,大部分是说

sqlplus/nolog

connect / as sysdba

startup force

或者sqlnet.ora中SQLNET.AUTHENTICATION_SERVICES= (NTS)注释掉等等,这些方法在我机器上试验过一概不管你用。于是努力的想昨天究竟干了哪些“坏事”,

想起我虽然没有改机器名或IP,但是作了一个操作是:使用Oracle Net  Configuration新建了一个本地网络服务名配置的连接,本来是要尝试连接测试机服务器的,,但是没配置成功,于是我很渴望这个错误和这个有关,就把这个新配置的连接通过Oracle Net  Configuration工具删除,然后重启oracle的两个服务,sqlplus终于能连上数据库了。谢天谢地。

我想出现shared memory realm does notexist的原因会有很多种,写出来给大家参考。
