without them, it is so much easier once you're familiar with these tools. 90 4 Robert Sheldon SQL Server Business Intelligence Development Studio (BIDS) provides several tools you can use to troubleshoot error handling in ssis 2008 the data flow of a SQL Server Integration Services (SSIS) package. The tools let you sample a subset of data, capture data flow row counts, view data as it passes through data paths, redirect data that generates errors, and monitor package execution. You can use these tools for any package that contains a data flow, regardless of the data's source or destination or what error handling in ssis code project transformations are being performed. The better you understand the debugging tools, the more efficiently you can troubleshoot your data flow. In this article, I demonstrate how each debugging tool works. To do so, I set up a test environment that includes a comma-separated text file, a table in a SQL Server database, and an SSIS package that retrieves data from the text file and inserts it into the table. The text file contains data from the Person.Person table in the AdventureWorks2008R2 database. To populate the file, I ran the following bcp command: 1 bcp "SELECT TOP 10000 BusinessEntityID, FirstName, LastName FROM AdventureWorks2008R2.Person.Person ORDER BY BusinessEntityID" queryout C:\DataFiles\PersonData.txt -c -t, -S localhost\SqlSrv2008R2 -T After I created the file, I manipulated the first row of data in the file by extending the LastName value in the first row to a string greater than 50 characters. As you'll see later in the article, I did this in order to introduce an error into the data flow so I can demonstrate how to handle such errors. Next I used the following Transact-SQL script to create the PersonName table in the AdentureWorks2008R2 database: 123456789101112 USE Advent

Gepubliceerd op 27 nov. 2013by Andy Brownhttp://www.wiseowl.co.uk - Learn how to debug packages in Integration Services. This tutorial first shows how to use the output window to solve run-time problems, then shows how to use data viewers to resolve data flow issues and breakpoints to monitor the progress of control flow tasks. If you'd rather learn from a human being, you might like to consider attending our two-day SSIS course - you can see the course outline at http://www.wiseowl.co.uk/courses/ssis....Wise Owl run lots of other training courses, in all things SQL Server, .NET and MS Office - visit our website at http://www.wiseowl.co.uk for more information.

take to rerun failed package from a point of failure.In other words you might not want successful tasks to run again if you restart the package.Checkpoints can be used to reduce the time http://microsoft-bi-certification.blogspot.com/2011/03/debugging-and-error-handling-in-ssis.html it will take to rerun a failed package.Here is what happened if you run a package that has checkpoints enabled.1.)Package checks to see if the checkpoint file existsIf the file does http://geekswithblogs.net/NibblesAndBits/archive/2012/04/13/ssis-debugging-tip-using-data-viewers.aspx not exists(ie it is deleted) the package begins at the first task.If the file exists the package reads the file and finds out where to start(including updating the values of variables and error handling connections at the time of the last failure).After you enable checkpoints in package, the final step is to set checkpoints at the various tasks within your package. To do this set the FailPackageOnFailure property at each task or container as True.If a series of task must be completed as a single unit in which either all the tasks are successful and committed or error handling in all error occurs and none of the tasks are committed place the task within a sequence container and then set transaction option property as RequiredTo ensure transactional consistency of the data that is affected by the SSIS package, you can make use of transaction settings on control flow executable.This will ensure that if the executable succeeds then the data is committed, if it should fail it will roll back the work performed by the executable to ensure data integrity.Isolation level defines the level of concurrent access on the task . The least concurrency is chaos and the max is Serializable2.)Identifying Package Status:MaximunErrorCount control flow property lets a package continue to run to completion even if there are errors that have occurred. The max number specifies the number of errors that can occur before the package will stop executing and report failure.Whenever a package is executed outside the debug environment the tab name execution results lists the error and warning description, execution times, final destination row counts and other execution information.3.)Configuring Execution Logging:Logging is used to understand what aspect of the package caused the package failure so tha
<< Controlling soft errors and false alarms in SSIS | Home | Adding a Control Flow to SSIS Event Handler >> SSIS Debugging Tip: Using Data Viewers Comments (3) | Share When you have an SSIS package error, it is often very helpful to see the data records that are causing the problem. After all, if your input has 50,000 records and 1 of them has corrupt data, it can be a chore. Your execution results will tell you which column contains the bad data, but not which record…..enter the Data Viewer. In this scenario I have created a truncation error. The input length of [lastname] is 50, but the output table has a length of 15. When it runs, at least one of the records causes the package to fail. Now what? We can tell from our execution results that there is a problem with [lastname], but we have no idea WHICH record? Let’s identify the row that is actually causing the problem. First, we grab the oft’ forgotten Row Count shape from our toolbar and connect it to the error output from our input query. Remember that in order to intercept errors with the error output, you must redirect them. The Row Count shape requires 1 integer variable. For our purposes, we will not reference the variable, but it is still required in order for the package to run. Typically we would use the variable to hold the number of rows in the table and refer back to it later in our process. We are simply using the Row Count as a “Dead End” for errors. I called my variable RowCounter. To create a variable, with no shapes selected, right-click on the background and choose Variable. Once we have setup the Row Count shape, we can right-click on the red line (error output) from the query, and select Data Viewers. In the popup, we click the add button and we will see this: There are other fancier options we can play with, but for now we just want to view the output in a grid. WE select Grid, then click OK on all of the po
