ORA-02041: client database did not begin a transaction

.NET中访问Oracle数据库链接：ORA-02041: client database did not begin a transaction 问题的处理。

.NET中访问Oracle中带有DB_LINK时对象时，会抛出一下异常

ORA-02041: client database did not begin a transaction

 

解决方案：

1.

To resolve the issue with Oracle's ODP.NET, you'd specify "enlist=false" in your connect string. 

Microsoft's ODP.net has the same connection string attribute, but it does something different.  I think what you want to use with system.data.oracleclient is OmitOracleConnectionName.

To Resolve this problem, you only have to include "Omit Oracle Connection Name=True;" in your connection string, for example:

"User Id=MyUser;Password=MyPassword;Data Source=MyDB;Omit Oracle Connection Name=True;"
