Oracle的OracleBulkCopy不支持事务处理

在进行OracleBulkCopy批量数据导入的过程中使用事务后抛出了异常，

没使用事务时可以正确批量导入，

ORA-12154：无法解析指定的连接字符串，

但是TNS配置肯定是没有错的，

难道是ConnectionString不是这样写了，执行事务时发生了变化，

还有：

//暂时发现oracle的bulkCopy不支持事务处理

using (OracleBulkCopy bulkCopy = new OracleBulkCopy(conn,OracleBulkCopyOptions.UseInternalTransaction))

如果不支持事务，这个OracleBulkCopyOptions.UseInternalTransaction怎么解释。
