Restricting SSIS Transaction to a single connection manager

Question

I have a fairly complex ETL with two Connection Managers:

• InputDatabase
• OutputDatabase

InputDatabase is read-only, with IsolationLevel=ReadUncommited on the ETL. I'm currently using TransactionOption=Required on my container to enable rollback on failure.

Is there a way to only use transactions on OutputDatabase, since they are not necessary on InputDatabase? While the current implementation works, it requires setting up Distributed Transaction Coordinator on a server that should not need it, along with opening firewalls and ports.

Answer 1

This seems to be beyond the intent of the TransactionOption support.

To use transactions on a single data source:

1. Set the data source to RetainSameConnection=True
2. Add Execute SQL Tasks to BEGIN TRANSACTION, COMMIT TRANSACTION, and ROLLBACK TRANSACTION
