What’s New in SSIS for SQL Server 2012 – Slide Deck

The slide deck for the What’s New in SQL Server Integration Services in SQL Server 2012 presentation is now available (embedded below). Typically when I present the new functionality in SQL 2012, I stick to demos… but I put together this deck to show off most of the new features in slide form.



SSIS Quick Tip: Required Parameters

SQL Server 2012 introduces the new Parameter model. Setting a parameter’s Required property to True means that a value must be supplied at runtime by the caller of the package (dtexec, SSMS, SQL Agent, the Execute Package Task, etc). This means that although the parameter has a default value at design time, it will never be used once the project is deployed.


I have a package which loads a single flat file into a destination table. I’ve defined an InputFile parameter for the path of the file I want to load, and use it to set the ConnectionString of my Flat File Connection Manager. For my package to validate, I need to give it a default value (which points to a sample data file I can use for testing).


Setting Required to True for this parameter ensures that I won’t accidentally use it after deploying it to my test and production environments, as the package won’t run until I specify a new value.


This will hopefully prevent some of the painful-yet-amusing-because-they-didn’t-happen-to-me type stories I’ve heard over the years, like:

  • Having your ETL processes running for a week before you realize that you forgot to update a connection string, and have been updating the test data warehouse with real customer data
  • Loading sample data files that developers use for testing into your production data warehouse, causing such products as “YOUR MOM” and “I HATE THIS JOB” to show up on the company wide weekly sales report

Setting a Default Logging Level in the SSIS Catalog

One of the powerful features of the SSIS Catalog is that it can automatically capture logs for packages run on the server. The logging level is set to Basic by default, and can be changed when the package is run on the Advanced tab of the run UI (as shown below. This can also be done when scheduling the package through SQL Agent).

Logging level on Execute Package UI

You can set a server wide default logging level on the Catalog properties page.

  • Connect to the SQL Server instance using SSMS
  • Expand the Integration Services Catalogs node
  • Right click on the SSISDB node, select Properties
  • Change the Server-wide Default Logging Level setting (in the Operations Log category)

Catalog Properties

See What Events are Included in the SSIS Catalog Log Levels for more information.

What Events are Included in the SSIS Catalog Log Levels

Logging Levels

Packages run through the SSIS Catalog can automatically have their logs captured in SQL Server 2012. The SSIS Catalog provides four different log levels – None, Basic, Performance, Verbose. The default log level is Basic.

The table below shows which SSIS events are captured in the [catalog].[operation_messages] view in the four logging levels.


Level Events Notes
None None Captures enough information to say whether the package succeeded or failed, and does not log any messages to the [operation_messages] view.
Basic OnPreValidateOnPostValidate






Captures similar information to what is displayed on the console by the default when a package is run with dtexec.
Performance OnWarningOnError This log level is required to track the performance information for the run (how long it took to run each task / component, etc) but does not log all of the events captured by the Basic log level.
Verbose All events The Verbose log level captures all log events (including performance and diagnostic events). This logging level can introduce some overhead on performance – see details blow.

Note that additional information is captured and stored in other tables / views in the SSIS Catalog. For an overview of the Views related to package execution, see Jamie Thomson’s blog post – SSIS Logging in Denali.

When to Use Each Logging Level


While the None logging level provides slightly better performance than Basic, I don’t expect that it will be used too often in production environments. This logging level does not capture error and status messages, which makes diagnosing problems difficult. However, if you have Packages Never Fail ™, this logging level might be for you! (Hey, you can always re-run the package with a higher level if something goes wrong…)


This is the recommended logging level for every day use. It captures important events (like errors and warnings), as well as enough progress information to display what the currently active task is, and how long each task has taken (internally this information is stored in the [catalog].[executable_statistics] view).


The Performance log level should be used when you are doing benchmarking and performance tuning for your packages. While it actually logs less messages to the [catalog].[operation_messages] view than Basic, it captures a lot more events internally to analyze the performance of the data flow components. As a result, there is a bit more overhead during execution – packages run with Basic will actually run a little faster than Performance (in this case Performance means “give me all of the performance details”, not “run my packages as fast as you can”).


The Verbose logging level captures a lot of events (especially when using OLE DB connections, as they generate many DIAGNOSTIC events). Verbose should only be used when trying to debug or diagnose package failures.

Custom Log Events

The only log level that captures custom log events (i.e. special events that are raised with custom / 3rd party SSIS extensions or scripts) is Verbose. Due to the overhead that the Verbose level introduces, I recommend creating your own custom reports if you need to capture these custom events.

Upcoming Book – SSIS Design Patterns

Over the past few months I’ve been working on a book for SQL Server 2012 entitled – SSIS Design Patterns. I’m co-authoring the book with a fantastic bunch of SQL Server MVPs – Tim Mitchell, Jessica Moss, Michelle Ufford, and Andy Leonard. Details are now available on the Apress website and Amazon.

SSIS Design Patterns

SSIS Design Patterns is a book of recipes for SQL Server Integration Services (SSIS). Design patterns in the book show how to solve common problems encountered when developing data integration solutions. Because you do not have to build the code from scratch each time, using design patterns improves your efficiency as an SSIS developer. In SSIS Design Patterns, we take you through several of these snippets in detail, providing the technical details of the resolution.
SSIS Design Patterns does not focus on the problems to be solved; instead, the book delves into why particular problems should be solved in certain ways. You’ll learn more about SSIS as a result, and you’ll learn by practical example. Where appropriate, SSIS Design Patterns provides examples of alternative patterns and discusses when and where they should be used. Highlights of the book include sections on ETL Instrumentation, SSIS Frameworks, and Dependency Services.

  • Takes you through solutions to several common data integration challenges
  • Demonstrates new features in SQL Server 2012 Integration Services
  • Teaches SSIS using practical examples
What you’ll learn
  • Load data from flat file formats
  • Explore patterns for executing SSIS packages
  • Discover a pattern for loading XML data
  • Migrate SSIS packages through your application lifecycle without editing connections
  • Take advantage of SSIS 2012 Dependency Services
  • Build an SSIS Framework to support your application needs
Who this book is for

SSIS Design Patterns is for the data integration developer who is ready to take their SQL Server Integration Services (SSIS) skills to a more efficient level. It’s for the developer interested in locating a previously-tested solution quickly. SSIS Design Patterns is a great book for ETL (extract, transform, and load) specialists and those seeking practical uses for new features in SQL Server 2012 Integration Services. It’s an excellent choice for business intelligence and data warehouse developers.
