SSIS commit and Rollback

SSIS Commit Rollback

In SSIS each and every component will commit its transaction after it got executed. But if we have a scenario where the commit should take place only after a set of component execution in ETL and for this we have an option in the Connection Object – > Properties -> Set RetainSameConnection as True.

This will ensure to commit only if all the components went success belongs to the same connection object.

You can give explicit commit statement like

  1. Begin Transaction
  2. Commit Transaction
  3. Rollback Transaction -> This you can write under the ONERROR event

What is the transaction support feature in SSIS and how to configure it?

transaction support feature SSIS
If a package fails in the middle then SSIS used this functionality to start the execution from the place where it failed. Also the transactions gets roll-backed aswell if needed.
Supported – Parent object has initiated a transaction and child package will participate in it this transaction
Required – This will create and start a new transaction
NotSupported – This will not support the transaction
We need to enable MS DTC (Microsoft Distributed Transaction Coordinator) Windows Service for transaction support
