SSIS : ErrorCode OnInformation EventHandler

Feb 18, 2008


Within my SSIS packages I use a logging logic quite similar as the one described by Jamie Thomson here :

But I still have a small "problem". When my package end with success the ErrorCode returned at the OnInformation event handler level is :




Committing distributed transaction started by this container.

Instead of :




Package "__" finished successfully.

Another example.

When there's an integrity constraint violation, I've got the following ErrorCode returned :




Thread "__" has exited with error code __.

Instead of :




The data value violates integrity constraints.

Anyone has a clue ?

Thanks a lot by advance.

SSIS OnError Calling Package Level Event Handler Twice..little Help Here!

Oct 6, 2006

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.

Bug? OnTaskFailed Vs. OnError

Nov 5, 2007

Hi everyone,

I have a package setup like this:

PackageA -> ContainerA -> ContainerB -> ExecutePackageTaskA (calls PackageB)
PackageB -> ScriptTaskA

If an error occurs in ScriptTaskA from PackageB, the OnError event handler in PackageA fires once and catches the event from ScriptTaskA; that is, the output of the SourceName system variable is "ScriptTaskA" from PackageB. So far so expected.

Now, the same error is handled differently by PackageA's OnTaskFailed handler. The OnTaskFailed handler fires twice - once for ScriptTaskA and once for ExecutePackageTaskA; that is, two outputs are returned - one for "ScriptTaskA" and the second one for "ExecutePackageTaskA". That's strange to me.

Why does the OnError handler only fire once and the OnTaskFailed twice? Is there a setting that does this?

Thanks in advance,

Logging Using OnError Event

Aug 30, 2006


We are generating log file in our SSIS package by enabling the built-in feature of SSIS tool. We are generating log for the "OnError" event. This also recorded the error/failed task messages in the text file "log.txt". That error information is too complex with more unwanted information like below

----------------OnError,,,pkgExtract,,,8/30/2006 11:50:04 AM,8/30/2006 11:50:04 AM,-1071636471,0x,An OLE DB error has occurred. Error code: 0x80040E21.
An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80040E21 Description: "Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done.".

OnError,,,pkgExtract,,,8/30/2006 11:50:04 AM,8/30/2006 11:50:04 AM,-1071607780,0x,There was an error with input column "create_user_id" (116) on input "OLE DB Destination Input" (103). The column status returned was: "The value violated the integrity constraints for the column.".

OnError,,,pkgExtract,,,8/30/2006 11:50:04 AM,8/30/2006 11:50:04 AM,-1071607767,0x,The "input "OLE DB Destination Input" (103)" failed because error code 0xC020907D occurred, and the error row disposition on "input "OLE DB Destination Input" (103)" specifies failure on error. An error occurred on the specified object of the specified component.

This is infact not in a better readable format. We also don't want to do our error logging in database.

Is there any way of defining our error log and create error error log with customization of our messages . Can we do it using OnError event handler.

Please help us with some good solution to avoid giving this confused error log messages.

OnError Event Handeling

Apr 17, 2007


I am having a few problems getting the opomum configuring the OnError event hendler for my new package. What im trying to do is log the Error event and sound out an email (which i am achiving) where i am encountering a problem is trying to determin the severity of the error.

What i would like to achive is to send an email and log the error (as i currently do) but if the error has the power to stop the package from executing i would like to fire an additional script to move the loading files to a failed location.

My initial thoughs were to put an expression the on the procdural constraint in he error handeler but i cant find which System variable to apply the logic to.

Anyone any suggestions?

The IDtsEvents.OnError method has a boolean return type whereas most of the other methods on that class are voids.

Why does OnError return a boolean?
What is the effect of returning true?
What is the effect of returning false?

OnError Script Error

Nov 2, 2006

I am using following script to combine all the System:ErrorDescription on OnError




Dts.VariableDispenser.LockOneForWrite("Errordesc", vars)


errNumber = CType(vars("ErrorCode").Value, Integer)

errDescription = vars("ErrorDescription").Value.ToString()

errSource = vars("SourceName").Value.ToString()

errdesc = vars("Errordesc").Value.ToString()

vars("Errordesc").Value = errdesc + errNumber.ToString() + vbNewLine + vbNewLine + _

errDescription(+vbNewLine + vbNewLine + _


Please note that "Errordesc" is the variable which I declared on script as readandwrite variable.

But on execution of this script I get error

Error: A deadlock was detected while trying to lock variables "User::Errordesc" for read/write access. A lock cannot be acquired after 16 attempts. The locks timed out.

any sugestion...

Please note that without ErrorDesc, the script runs successfully

Question About OnError Event

May 20, 2008

Hi guys,

I have a package name "Package1" and I have a few data-flow tasks in it.
whenever anything fails in the "Package1", I want to send out the failed email to alert myself.
So first step, I went to EventHandler tab, and select Executable as "Package1" and Event Handler as "OnError".
and then I added SendMailTask. I manually ran SendMailTask, failed email send to me okay.
But when I run package from Microsoft visual Studio (IDE), the package failed but it doesn't send out failed email.

Error code:
[174]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "xxx" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.

Maybe I misunderstand OnError eventhandler, or I set up it wrong.

OnError And OnTaskFailed Can Not Fire Event

Apr 15, 2008

I have a package which have two sequence container, first container is used to transfer data to a staging area and second sequence container is used to transfer to destination from that staging area. And I also apply transaction required to second sequence container.
There are several execute sql tasks and several data flow tasks inside two sequence container.
first sequence container( 1.execution sql task-> flow ->3.execution sql task) ->
second sequence container(4.execution sql task-> 5.execution sql task-> flow-> flow -> 8.execution sql task-> flow...)

I create ExecutionLog table which is used to log status for this package on our sql server. First this status field is null, then during this package run , it change to 'in process', and after this package finished, it change to 'success' or 'failure' depending this package can run successfully or not.
This package can be run only if status is 'success' ,'failure' or null. So I need to change this status field during package execution.
For updating package to failure, I need to add event handler to change that status using execute sql task.

First time I perform to execute sql task on onError event handler tab (this event handler is applyed on package level ) .
And for testing envent handler I use old schema version to make sure I get failure for '8 execution sql task'.
But package seems to get stuck at '8 execution sql task' inside second sequence container( always yellow when I run from ssis) and never fire envent handler. '8 execution sql task' is used to update related table.

Second time I remove onError envent handler and change to use on onTaskFailed event handler tab (this event handler is applyed on package level ) .
But everything is the same as using onError event handler except I got error output but still can not fire event.
Why '8.execution sql task' can not fire onError or onTaskFailed?
For this case what kind of event handler I need to use, what kind of level I need to apply for this event handler.

Get The Err?r Message In OnError Event Hanlder

Aug 10, 2006


I want insert data into table from csv file, so I put a data flow task on control flow tab,

a flat source and a ole db dest on data flow tab. They work well.

Then to get the error log I put a script task on event handler tab, in this script task I want to

output the error description to a txt file while the data flow task fails for any reasons

such as constraint failure etc.

In this script task I think I can get the error description by using property Err.Description,

but Err.Description is empty while data flow task fails.

How can I get the error description in the script task on event handler tab.

Nov 2, 2006

I used onError event to send email in case ssis pckage fails

but it send multiple email with errordescription. for ex below are the errordescription of four diferent emails i received.

Thread "WorkThread0" has exited with error code 0xC0047039.
An error occurred with the following error message: "The connection "{01AF859A-CF97-4F6C-9C78-1AA4B1C9C27B}" is not found. This error is thrown by Connections collection when the specific connection element is not found.".
Thread "SourceThread0" has exited with error code 0xC0047038.
The PrimeOutput method on component "Flat File Source - Read from source file" (1) returned error code 0xC0202092. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.

Can anyone suggest if we can combine all this error description and send this as one email.

Locked Excel File Due To OnError

Sep 2, 2007

I have a package the looks for any Excel files in a folder, moves the data to a SQL table, then archives the file to one of two archive folders--a success folder or an error folder. I have an OnError handler on the Data Flow that sets a flag that lets the archive process know where to move the file.

This works when the processing is successful. It also works when the error in the Data Flow occurs right off the bat, i.e., in the Source. When the error occurs later on, say in the Destination, it doesn't work correctly. In this case, the OnError sets the flag, but when the archive process tries to move the Excel file, it can't because it's locked. I assume this is because OnError interrupted the Data Flow before the Excel file could be closed properly.

Any ideas on how I can avoid this problem? Can I manually get the Data Flow to close the Excel connection somehow?

OnError Alert User Though Interface??

May 22, 2006

I have a SSIS package which takes excel spreadsheets (exported from MS Project) and imports them into tables in my database. I have each step of my control flow set up with "On Success" so it only continues if the previous step was successful.

My next step is to create a page and/or web part so that I can have my user click a button to launch this SSIS and import this data. I have seen articles on how this could be done via code - so I assume it can be done. But what I cannot find is how alert the user if an error has occured in the execution of the SSIS.

How can you alert a user that a package you executed though in the front end errored?

Could I build something in to the OnError handler that returns the error and have that error returned to the front end App??

Any insight/examples for this would be much appreciated.

System:ErrorDescription Vs. OnError Error Details

Nov 12, 2007

Hi all,

I have a Script Task in an OnError EventHandler, the Script Task is used to send an Email to notify about the Execution Error. I'm currently using the System:ErrorDescription variable in my Script Task to provide details about the error but I have noticed that the Error Description written in the Windows Event Log when using OnError Logging is much more detailed than the content of the System:ErrorDescription variable. How can I use the same Error Description in my Script Task ?

I'll appreciate any help.

Rerun Data Flow Task OnError

Oct 3, 2007

I'm very new to using SSIS. I have a large number of SQL databases (archived .mdf/.ldf files) with data that needs to be imported into one giant database. My problem is that half of the databases are missing a column that was introduced in a newer version of the database schema and when my package executes my data flow task it errors out. I basically get a message stating that it cannot prepare any statements because the SQL command that I am using is trying to select column data from a column that doesn't exist.

I figured that I could set the OLEDB Source inside of my Data Flow to have a Data Access Mode = SQL command from variable. The variable bound to the component is called "MySelectQuery" and is initially set to my "new format" query. From there I could create an event handler for the OnError event of the Data Flow Task, switch value of "MySelectQuery" to equal the "old format" query and rerun the Data Flow Task.

I'm not sure how to accomplish restarting my Data Flow Task after changing "MySelectQuery" in the OnError event. I just tried setting up the package to use CheckPoints but it doesn't seem to be working right for me. When I restart the package it starts over even though there is a checkpoint file that seems to have captured the state after the failure.

Any ideas?

How To Abort Package Execution Programmatically OnError

Aug 8, 2006

Context: I have a web page that uplaods a file that is then imported to the database via an SSIS package.

Problem: If and when the package encounters an error, I want to surface that error to the user via the web page.

Approach: I derived my own class from the DefaultEvents class and then overrode the OnError event handler to catch any errors raised during package execution. I then pass my class to the package Execute method.

Results: The OnError is triggered, but I don't know how to abort package execution nor how to pass the error context to the user. I tried raising a custom exception in the OnError handler, but it failed to propogate to the calling code (ie the code that executes the package).

Another approach would be to write to a database table and then do a query from my web page after the package is done executing (alternatively, I could generate a log file). Seems like a lot of work though. All I want is to pass the error context back to my calling code so I can tell the user what happened.

Thanks in advance for your help.

OnError Event Firing Multiple Times

Oct 22, 2007

I have an SSIS package that contains a For Each Loop Container. I have three Data Flow tasks within the container. I have an OnError event handler associated with the encapsulating container. When one of the Data Flow tasks within the For Each Loop Container fails, the OnError for the Loop Container gets called 5 times. The OnError handler is just a script task that sends a notification email. I am not explicitly Dts.taskresult = failure, nor am I calling FireError.

OnError Event Handler And Custom Logging

Apr 18, 2008

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?

In Debug OnError Sends Email But Does Not Finish

Is there something I havn't set up correctly?

Package Level OnError Event Handler Not Firing (as If Not There)

Mar 26, 2008

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?

Will OnError Event Fire If I Use Try/Catch In Script Task?

Feb 4, 2008


We have a package that runs on 3 servers, all based in different countries and time zones. Each package does logging to a common SQL Server based in New York. (We log to the same server to make monitoring of the package run results easier.) We expect that our overseas servers will occassionally fail to make a database connection and have coded a Try/Catch block in our Script task to ignore errors that occur when attempting the SQL Server logging.

The problem is that the OnError event handler defined at the package level is being called whenever a server fails to make a database connection. The Catch block appears to not be called at all. I've included below the short method that does the SQL Server logging. The "Dts.Log" line logs to a SQL Server and usually works. However, when it fails, the "WriteEventLogEntry" method is supposed to be called to write an error to the server's event log. (I haven't included the "WriteEventLogEntry" code but it works fine when called elsewhere in the package to do our non-error event logging.)

Public Sub WriteSqlServerLogEntry(ByVal logMessage As String, ByVal dataCode As Integer, ByVal dataBytes() As Byte, ByVal rowsInserted As Integer)


Dts.Log(logMessage, dataCode, dataBytes)

Catch ex As Exception

WriteEventLogEntry("An exception was thrown while attempting to log the following message to the SQL Server provider: " + logMessage, EventLogEntryType.Error, rowsInserted)

End Try

End Sub

Shouldn't a Catch block prevent the OnError event from being raised? How can I change my package to ignore all errors that occur when attempting SQL Server logging?

Integration Services :: OnError Event Handler Not Firing

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.

Integration Services :: Executing Child SSIS Package In Parent SSIS

I want to achieve the following in (SSIS/SSDT for SQL 2012) - 

I have a generic SSIS package which simply sends out email notifications using SMTP email task (this package is within its own project, and has project level input parameters).

I need to be able to call this package in the Event handler section of every package (numbering in about less than 60) that we have. These packages are within their own respective projects.

I thought I could use the "execute package task", but it turns out , using this, I cannot call a package that is part of some other project. I also cannot call a package that is stored in the CATALOG. Is there any way I can do this ?

When I call the child package , I should be able to send in parameters like - error information and package name of the Parent package.

SSIS Called From Agent Job Not Calling New Child SSIS Package Addition

Oct 29, 2007

I have an SSIS package (TransAgentMaster) that I recently modified to include a call to a child package via the file system. The child package creates a text file. When I run the package in dev studio then the child package/text file is produced.

I then imported the TransAgentMaster as a stored packagesfilesystem package into SQL SSIS and executed the package. The child package produced the text file.

I then ran the SQL Server Agent to see if the child package would work and it did not generate the text file. Thus after updating a SSIS package importing the package into SSIS the job that calls the package will not call the child package. Please not that the TransAgentMaster package calls 7 children packages just not my new one.

Any thoughts why the agent will not run the child newly crated childe package?
