故障分析:

从错误现象上来看,应该是监听的问题,其报错大概意思是监听程序无法识别当前描述符中的连接服务。那么既然是这样的话,我们通过手工指定描述符中的连接服务,我想故障应该就可以排除了,那么手工指定描述符中的连接服务也就是我们所说的静态监听注册方式,默认采用的是动态监听注册方式。

故障解决:

1、编辑$ORACLE_HOME/network/admin/listener.ora,在文件添加内容,使其成如下样式即可,(红色部分为新添加的内容;保存后执行lsnrctl stop/start重启监听即可

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /DBSOFT/product/11.2.0/db_1/)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = wwl)

(ORACLE_HOME =/DBSOFT/product/11.2.0/db_1/)

(SID_NAME = wwl)

)

)

2、再次通过监听连接数据库测试,能够正常登录数据库,故障排除。

3、从ORACLE 10G开始,不再有8080端口,这样将不会与tomcat的默认端口产生冲突,,从而导致修改端口的尴尬现象。
