Omiting tnsnames.ora
This is another type of Oracle connection string that doesn't rely on you to have a DSN for the connection. You create a connection string based on the format used in the tnsnames.ora file without the need to actually have one of these files on the client pc.

Using Connection Pooling
The connection pooling service will create a new pool if it can't find any existing pool that exactly match the new connections connection string properties. If there is a matching pool a connection will be recycled from that pool.

Utilizing the Password Expiration functionality
First open a connection with a connection string. When the connection is opened, an error is raised because the password have expired. Catch the error and execute the OpenWithNewPassword command supplying the new password.

2.配置net configure的服务名
3.数据库名是你配置的服务名
在ORACLE_HOME目录，如c:\Oracle\Ora92
点击鼠标右键->属性->安全，
对ASP.NET 帐户赋予允许读、执行权限，并在“高级”中保证该目录的子目录、文件都继承这些属性，确定。再次启动项目就可以正常运行了。不知是否还有别的方法？
