SET_NLS对Oracle ODP.net进行故障转移

问题描述

我尝试使用ODP.NET从c#程序中执行以下语句:

I try to execute the follwing statement from a c# program with ODP.NET:

string sql = "BEGIN dbms_session.set_nls('NLS_NUMERIC_CHARACTERS','''.,'''); END;";
        using (OracleConnection connection = new OracleConnection("Data Source=db;User Id=a;Password=b"))
        {
            connection.Open();
            using (OracleCommand command = new OracleCommand(sql, connection))
            {
                command.ExecuteNonQuery();
            }
            connection.Close();
        }

我检索了以下错误消息:

I retrieve the follwing error message:

ORA-02074:无法在分布式事务中设置NLS

我在代码中不使用任何交易. OracleConnection是隐式分布式事务吗?如果我在连接字符串中添加 enlist = false ，它将起作用.但是我不知道为什么.

I don't use any transaction in my code. Is the OracleConnection an implicit distributed transaction? If I add enlist=false to the connection string it works. But I don't know why.

推荐答案

我在我的环境中不需要分布式事务，因此我只是通过在连接字符串后附加enlist=false来解决此问题.希望它对某人有用.

I don't need distributed transactions in my environment, so I just solved this by appending enlist=false to my connection string. Hope it may be useful to someone.
