Developer Suite连接数据库的问题，劳驾高手指点！
电脑里面同时装了OraHome92和DevSuiteHome2，前者的sql*plus能访问，后者的则不行。输入scott/tiger登陆后者时，我输入了"主机字符串"号以后，报错：
ORA-12154: TNS:无法解析指定的连接标识符
******在网上找了很长时间都找不到合适的对策，其中有人建议：
1.打开OC4J listner, 然后在dos命令中输入'lsnrctl start listener'，报错如下：
Copyright (c) 1991, 2002, Oracle Corporation. All rights reserved.
启动tnslsnr：请稍候...
Service OracleOraHome92TNSListener already running.
TNS-12560: TNS: 协议适配器错误
TNS-00530: 协议适配器错误
32-bit Windows Error: 1056: Unknown error

2.国外网站上人家的建议
ORA-12154: TNS:could not resolve the connect identifier specified
Cause: A connection to a database or other service was requested using a connect identifier, and the connect identifier specified could not be resolved into a connect descriptor using one of the naming methods configured. For example, if the type of connect identifier used was a net service name then the net service name could not be found in a naming method repository, or the repository could not be located or reached.
Action: - If you are using local naming (TNSNAMES.ORA file):
- Make sure that "TNSNAMES" is listed as one
oracle连接啥这么复杂啊.
oracle 10g
用ps/sql dev怎么也连不上.
用sqlplus可以登陆.net manager之前测试连接了成功的.现在搞得也连接不了.
listener.ora:
SID_LIST_LISTENER =
(SID_LIST =
......
兄弟 图挂了。
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value ......
