Distributed Transaction on Linked Server between sql server and mysql

Question

I have a table say Table1 on SQL Server 2014 and MySQL both.

Table1
ID INT,Code VARCHAR(100)

I created a linked server M

Answer 1

As on SQL 2014, you could have configured the linked server not to enlist in a distributed transaction. Although you could try adding "Enlist=false" in the @provstr argument to sp_addlinkedserver

Answer 2

Theoretically this should work.

I would suggest different steps to sort this out:

1. Have you checked you MySql storage engine yet? It looks only InnoDB storage engine support distribute transaction per MySql document: https://dev.mysql.com/doc/refman/5.7/en/xa.html

2. See if you can switch to use MySQL Connectors setup connection to connect to MySql in SQL Server instead of OLEDB provider, which state by MySql document above that support distribute transaction.

3. If still not working, it might be the MSDTC service itself has some problem, see if you can isolate that like get a SQL Server instance running on the MySql server box(if you are using Windows MySql), or try install Windows MySql on the Sql Server box to get distribute transaction working between two MySql. Which would be able to point you to the actual problem.

EDIT:

Unfortunately it looks that you proved this not working, I've a closer look at the MySql document and sorry it looks that I wasn't reading it thoroughly, it says:

Currently, among the MySQL Connectors, MySQL Connector/J 5.0.0 and higher supports XA directly

And by some other Googling I found this: https://bugs.mysql.com/bug.php?id=37283, people report this bug many years ago and they marked this as a won't fix.

Some one suggested something here: https://social.msdn.microsoft.com/Forums/en-US/fc07937d-8b42-43da-8c75-3a4966ab95f9/xa-msdtc?forum=windowstransactionsprogramming, which is to implement your own XA-Compliant Resource Managers to be used by your application (https://msdn.microsoft.com/en-us/library/ms684317.aspx)
