Same Event Handler For All The Tasks In The Package
Feb 12, 2007
Hi,
We want to develop an error handling process that will log the errors into multiple destinations (eventlog, text files or sql database) depending upon a variable set in the package. Also we want that this errror handling process should be initiated by all the tasks in the package on error.
Is this possible? Can the same event handler be called from multiple tasks in the package? Also in the event handler can we call another package which actually does the error handling. This way we have only one place to change our error handling process in case required.
Thanks in advance for your help.

Hi all,
I have a package on which i've applied a package level OnError event handler. The OnError event handler includes a Script Task (that builds up a string of errorCode, errorDescription, MachineName etc...) and a WebService Task that calls a webservice to send an email including the built up string from the script task in the body of the email. This has worked fine in one package where i've applied it but for some reason in a second package the existence of an OnError package level event handler seems to be completed ignored. I'm causing various package object to fail but the OnError handler never fires. I know the obvious answer is find what's different between the two packages but i can't see that any is different (in relation to package level OnError event handling).
Has anyone else come across this? Any suggestions?
Thanks
M.

My project currently has task which have their own individual event handlers that get called onError (setup event messages). I also have a package level event handler that performs a generic task (sending events to the windows eventviewer) In the package level event handler there is a script task that decides on a boolean variable whether to "Success" or "Failure" to different task. When I fail one task of the main control flow, the task level event handler runs, then the package level event handler runs, and then it also runs again for some unknown reason. The second time it runs it picks up the value of a variable set in the variables window. However, I change this value at runtime to the value from a database. I can't understand why it would run the second time, and if it did run why it would have the value from the variables window and not the value that is set in memory. It's like the event handler runs with the value from memory and then runs and picks the values back out of the variables window, replacing the db values and re-runs.
Maybe the package itself is failing all together and then re-runing the package level event handler?
Any help would be greatly appreciated.

I have created an event that contains a Data flow tasks with OLE DB source & Excel Destination.
This event is executed/triggered based on an execute SQL task failure in the control flow Sequence container.
However, when I execute the Data Flow task of the Event Handler, it runs successfully but fails when I execute the whole package.
I get the below error message:
[OLE DB Source [21]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "TK463DW" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
I have tried setting the property 'DelayValidation' to 'True' on all the Control Flow and Data Flow tasks on the package and on the Event Handler, but still I could not fix this.Not sure What I am missing.

Hi, I am trying to Log my activities when OnError event handler fires
I have defined few tasks in OnError event handler section so when there is a failer on the main package my OnError task runs ( which it work fine)
now I am trying to add Dts.LOG from inside OnError evend handler task, and it seems like SSIS doens't give that function.
I can use dts.log outside on the main package but not inside OnError section! any ideas
Thanks

HI, I'm implementing a custom error loggin using SSIS event handler, I succesfully catch the error and now I trying to retreave the value of this variables: System::ErrorCode and System::ErrorDescription.
The problem is that only the System::ErrorDescription retreave a value, the variable System::ErrorCode cames empty.
Is that correct?
Thanks.

Is the Onerror Event Handler from the tabbed window in the IDE the same as the red arrow paths that can be used in the control flows and Data Flows?
If yes, what and where is the best practice to use?
If not, can you elaborate?
Thanks,

I'm trying to log the information spit out by SSIS but only the rowcount part, e.g. "component xyz wrote 1000 rows", im currently using a execute sql task but that will log all information, any simple efficient way i can filter out that rows written line and log that into a sql server table?
thanks

I am current using Event Handlers in an SSIS package, but when adding a new EventHandler type eg. OnPreExecute, to an executable within the package, I am unable to see this new EventHandler defined in the hierarchical listing on the left hand combo box (named Executables).
Can't seem to find a Refresh option anywhere. I've only been able to see these newly created EventHandlers in the hierarchical listing by closing and re-opening the package.
Is this a 'feature' or am I missing a Refresh option somewhere.
Thanks.

Dear all,
Previously I've posted about precedence error that didn't work and now it works, thanks to John Welch for his support. But when I tried to use event handler, it won't work. When error occured it didn't redirect to the OnError event handler. And then I built another package but with Data Flow task only, put a simple Script task inside OnError event handler and strange..it worked fine. There is no differences between my first Data Flow task and the last Data Flow task, totally the same process. I've captured both execution result. This is the first failure Data Flow task and the last success Data Flow Task (failure and success herein means that OnError work or not)
And then I did some testing in my last package contains a success Data Flow task. I put a new Data Flow task by copy from the previous one, execute it and OnError won't work again. Then I delete it, execute the previous one and OnError worked fine. I really don't understand why by adding a new Data Flow Task then OnError event handler won't work ?
Any help would be appreciate. Thanks in advance.
Best regards,
Hery

SSIS Checkpoint and restart event handling.
I am using checkpoints in my SSIS packages which determines the step at which the package failed the last time and restart at that step.
But i need some other task also to kickoff only during restart? There is not an OnRestart handler as OnError in SSIS.
How can i do this ?

I have a task configured on the post execute event handler of a package expecting this task to be executed only once after the completion of all the other tasks in the package. But I found the task configured on the post execute event of the package getting executed as many times as the number of tasks in the package + 1 . Is there any workaround for this problem?

hi!
I am using a simple Data Flow within a Squence Controller and have added a Event Handler for OnPostExecute which contains a simple insert to a table, but this is not working. My package gets successfully execute but data is not getting inserted in the table used in Event Handler. I have also tried OnError, OnPackageFailer etc... but no results. Please guide.

Hi
I'm still fairly new to some of SSIS's enhanced funtionalities, one of them being Event handlers. I have tried creating a simple package, that simply contains a SQL Execute task that basically creates a simple table. Now i have then added a OnPostExecute even handler as a test which basically runs a script task that simply shows a msgbox. I have gone to execute the package, however after the completion of the SQL Execute task, nothing happens, the even handler doesnt get fired for some reason, i switch to the even handler page and the script task has not been executed. It is like this for every event handler i have tried, even the OnError event. Could this be a problem with my installation of SSIS or have i done something wrong?
Any help would be greatly appreciated as i have done SSIS training and to create an event handler was never this hard!
Regards

Hi,
I have an SSIS package that populates a field with "DEFAULT" at the start of execution and i have an Execute SQL task in PostExecute EventHandler that executes a stored proc to update the said field to "SUCCESS".
I already created a blank script task to connect to the Execute SQL task and placed in the precedence constraint editor: @[System :: PackageName] == @[System :: SourceName] so that it would execute only when the package completes execution.
My problem is that there are times (probably about 1 out of 50) that the "DEFAULT" value does not get updated. I dont know why this is happening because I expect that this should always be updated since the stored proc is in PostExecute (i suppose successful or even failed execution always does what is in the PostExecute event handler). I don't know why this is happening and it is so hard to replicate.
What do you think?
Thanks!

Not receiving any errors. The update runs perfectly on all fields, except for the added parameter during the sub. I need to change the hidden field's value after parsing out several fields in the form and generating a logfile entry of sorts. This needs to happen after all the form fields are updated, but before the update is executed.
aspx: (relevant parts only...)<asp:SqlDataSource ID="TicketDetails" runat="server" ConnectionString="<%$ ConnectionStrings:myConnectionString %>"UpdateCommand="UPDATE Tickets SET TicketSuspense = @TicketSuspense, TicketPriority = @TicketPriority, TicketLastUpdated = CURRENT_TIMESTAMP, TicketStatus = 'Assigned', TicketTechnicianNotes = @TicketTechnicianNotes WHERE (TicketID = @TicketID)"><UpdateParameters><asp:Parameter Name="TicketPriority" Type="String" /><asp:Parameter Name="TicketSuspense" Type="DateTime" /><asp:Parameter Name="TicketID" Type="Int32" /></UpdateParameters></asp:SqlDataSource>
codebehind: (once again, the relevant parts only)Protected Sub TicketDetails_Updating(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.SqlDataSourceCommandEventArgs) Handles TicketDetails.UpdatingTicketTechnicianNotesHiddenField.Value = "some text..." & TicketTechnicianNotesHiddenField.ValueTicketDetails.UpdateParameters.Add(New Parameter("TicketTechnicianNotes", TypeCode.String, TicketTechnicianNotesHiddenField.Value))End Sub

Is it possible to create an event handler in a VB.net application to run whenever a Stored Procedure is run.
My application has a scheduled task which is created and scheduled by users of the application, whenever this scheduled task is run I would like it to contact the application to kick off a sequence of tasks. I would appreciate if anybody could point me in the right direction.

Hi,
One of my plan is to develop a custom task compoent to log the errors into the destination provided as paramter to the component. Now how can I restrict the use of this component in the event handler tab only. can something like this be done?
Also extending this a little further, is the below thing possible?
The custom component should expose custom properties which should allow the user to add the destinations for logging the errors. It will be a predefined list (window event log, text file, sql table etc) and the user will be allowed to check what all he/she wants. Then if the user has selected sql table then ask for the oledb connection and the table name, if text file is selected the ask for the path of the file.
Apology if I am asking too many questions around the same thing (error handling). There may be a better way to acheive what I am trying to acheive but then I have no idea about it. Your guidance will be of great help.
Again, Thanks a lot for helping this extra curious guy who wants to try and develope generalized compoenents if possible.
Regards,

I'm trying to implement a custom log table. To keep the discussion simple, let's say I only have 1 column in this table and all I want to write in it are
"Start" when the package starts
"Error" when it encounters an error
"Finish" when the package finishes. Even if there was an error, I still want to enter "Finish'.
My Control Flow has 3 task objects, 2 Execute SQL Tasks, and 1 Data Flow Task in between them.
The first Execute SQL Task does an insert statement for the Start and the second Execute SQL Task does an insert for the Finish.
To capture any package errors, I also have an Execute SQL Task (to insert "Error") in the Event Handler for OnError. I see that when I cause an error in my package it can raise multiple OnError events, which will envoke my Execute SQL Task multiple times. (This is good because it will allow me to write a line per error event with the error description.)
The problem I have is, how do I write the "Finish" log when I have an error? If I put the insert for the finish in the same Execute SQL Task with the errors, then it will write a "Finish" for every error. But I can't put it anywhere else because if I put it anywhere else, the package never makes it there because it stops at the OnError Event Handler.
Or is there a way for me to tell the package to do the 2nd Execute SQL Task all the time?
Lastly, is there a better way to do this kind of custom logging?

Has anyone used Checkpoint files in conjunction with the OnError Event Handler ? I'm having a problem getting the OnError event to fire when the SSIS package reruns with the Checkpoint file.
The first run of the package (without a checkpoint file) works fine. The error occurs, the OnError event handler is called, the package stops and the checkpoint file is created.
When the package is restarted is goes to the correct spot (where the error occured) using the checkpoint file, then it throws an error within the For Loop container and does not call the OnError event handler. The OnError event handler is setup on the For Loop container. The ForLoop performs three loops. Each one of these loops creates an error. Not one of these errors within the three loops will trigger the OnError event handler...
Any help would be appreciated.
thanks

Hello,
Upon completion of a package the OnPostExecute event is fired whether the package was successful or not. As expected.
Then, I setup the package to use CheckPoints. I create a Script Task and set the Dts.TaskResult to fail. When the package runs and fails the OnPostExecute event for the package does not fire! If I remove the CheckPoints from the package, the OnPostExecute event fires.
What's even stranger is that if I set the Script Task to succeed, and then rerun the package, the OnPostExecute event still doesn't fire!
Has anyone else noticed this? It seems to me that the OnPostExecute event should fire whenever the package completes as it does when CheckPoints are not used. Why would it not fire when using CheckPoints?
Thank you,
Langston

I have created an OnError Event Handler to catch an error in the Execute SQL Task in the Control Flow. On error I am simply inserting a few parameters in a DB table using Execute SQL Task. I followed the instructions in: [URL]....
Now when I run this error hanlder task manually it runs fine but when I purposely fail the SQL Task it never fires the error handler. I am not sure why. I checked the DisableEventHandler property and it is set to False.

Is there any differene between on-error event handler and precedence constrain failure? I have created a package and if a data flow task(flat file to DB) fails, the file has to be moved to archive folder. How I have accomplished this is Dataflow task->precedence constrain failed(red arrow)->execute process task to move the file to error folder and it worked,The same execute process task( to move the file to error folder) doesnot work when I move this to on-error event handler. Also, for the same file the on-error event is getting triggered multiple times.

Thanks in advance in reading this thread.
I have developed a big SSIS package to extract data from flat-files ( + 200 Dataflows ).
The situation is the following, inside de SSIS package, there are a lot of validations before extracting & loading the flat-files, i'm running this validations in paralell, so that when a file arrives, it enters the "validation process" and start extracting the file.
When i run the SSIS package from BIDS it works the way i have concepted it... but when i run the ssis in the server, the tables that are loaded through the process are only "available" when the SSIS PACKAGE ends, it is imperative that trough the process, when a table receives new data, it becomes ready, and don't just be available when the SSIS package finishes...
I have attached the an lousing .jpeg.
It is importart for the tables to be available, so the stored procedures(OUTSIDE SSIS PACKAGE) that are dependent of some tables, start working before the SSIS package Ends.
Thanks in Advance.

Hello,
I have done a search and have read some of the posts, but am left more confused than before. I am fairly new to SSIS. Here is my situation and what i am trying to accomplish.
I have a package that has a sequence container, in which there are multiple SQL tasks (about 20) running in parallel. I have checkpoints enabled, and FailPackageOnFailure enabled as well. If the package fails, when i re-run the package it will run the last task as well as all the other tasks. What I am looking to accomplish is when the package is re-run, have the SQL tasks that failed ran and not the previous successful tasks.
I think the best way would be via disabling tasks on successful completion of a task, where it writes the name of the SQL task to a temp table, but I am skeptical.
Can anyone point me in a direction to help me accomplish what I am looking for please.
Thanks in Advance.

This may sound a little anal-retentive, but I have a number of SSIS packages that, when I open them, the first thing I have to do is scroll to the left or up to get to where the tasks are displayed. Even if I move the tasks right or down, they still end up in that initial position. This happens even if I use auto arrange.
Is there a way for me to set the package so it has a consistent point or display at which it opens?

I have several sequence containers in one package that fire off execute package tasks. I would like each of the sequence containers to start at the same time when the job starts running. However when I set them up to do that, i get an error that the variable cannot be read because it is locked. I have the variables setup as readonly so not sure why they are being locked. When I run the package and have each sequence container fire off after the previous one ends it runs fine.
Any ideas on how to get around this?
Thanks!

I'm trying to do some custom SSIS logging using event handlers, similar to the ideas provided by Jamie Thomson in the past. My problem is that when I use System:ourceID as one of the items to be logged, I can't match up the SourceID to any of the GUIDs that are displayed in the property window for the various tasks in my package.
Where is this sourceID coming from and how can I track it down?
Thanks for any insight on this.

Hi there,
I'm trying to keep track of the ETL process inserting/updating a row in one table for each package that finish in my ETL process when executing. So far, I created a Script task that increments by one a variable (counter) and then open a connection to my database an insert/update my table. What I want to see is Step 1/30, Step 2/30 and so on. Right know I can display Step 1, Step 2 but how can I get the overall number of tasks within a package?
Thanks in advance for any help you can give me.
Sincerely,
Ricardo
