从 SQL 服务器存储过程插入 DB2 数据库成功，但使用实体框架包装相同的过程失败

Question

I need to be able to insert rows into a set of tables in a DB2 database from a Microsoft SQL Server database. I created stored procedures that can insert rows into the DB2 database using a linked server, referencing the target tables by their 4 part names. These procedures work and I am able to insert records by calling them in SQL Server Management Studio.

The schemas are different between the two databases, so I am using a C# program and Entity Framework wrap these stored procedures to help me perform the mapping. When running my program an exception is thrown with the message

The operation could not be performed because OLE DB provider "IBMDASQL" for linked server "LinkedServer" was unable to begin a distributed transaction

Running a SQL trace and replaying the commands created by Entity Framework in SQL Server Management Studio creates the desired records in DB2.

What am I missing here to get these stored procedure calls working from Entity Framework?

Answer 1

My problem was solved by setting a configuration property in my database context.

db.Configuration.EnsureTransactionsForFunctionsAndCommands = false;
