If I use OnError event handler in my SSIS package, there are variables System::ErrorCode and System::ErrorDescription from which I can get the error information if any things fails while execution.
But I cant the find the same for OnTaskFailed event handler, i.e. How to get the ErrorCode and ErrorDescription from the OnTaskFailed event handler when any things fails while execution in case we want to only implement OnTaskFailed event handler for our package?
This might be helpful, it's a list of all system variables and when they are available.

I've just run into the same issue, and I've worked around it by :
Creating a #[ErrorCache] variable
In my case the task was being retried multiple times, so I needed an Expression task to reset the #[ErrorCache] variable at the beginning of each retry
Create an OnError event handler, which contains an Expression task purely to append the #[ErrorMessage] to the #[ErrorCache]
Create an OnTaskFailed event handler which then utilises the #[ErrorCache]
Go to the event handler of the task you want to monitor for errors and click on the link to create a new handler.Then create a task like Send Mail and create 2 variables: mail_header and mail_body.
IMPORTANT: Move the variables from the current scope to the OnError scope otherwise the values won't be available when processing the package.
Define the mail_subject variable as string and set the expression as: "Error " + #[System::TaskName] + " when executing " + #[System::PackageName] + " package."
Define the mail_body variable as string and set the expression as: REPLACENULL( #[System::ErrorDescription],"" ) + "\nNotify your system administrator."
On the task editor, create an expression assigning Subject to the #mail_subject variable. Define the MessageSourceType as a variable and set MessageSource to the #mail_body.
In the task that you put on the error event handler you can select parameters that are only available in an error handler such as system:Errordescription or system:Sourcename (which provideds the task that it failed on). We use these as input variables to a stored proc which inserts into an error table (and to send an email for a failed process) that stores other information beyond just the logging table. We also use the logging table to log our steps and in clude on error in that so general error information goes there.

I'm running a LoadRunner test , upon user failure at login /even at any other transaction it has to fail and execute log off portion of the script.
Note: I have put text check and with textcheck count if the transaction fails( using if condition I have handled it) it then ends transaction with fail status .I would need solution to perform log off also at the point where the if condition fails.
Can anyone share me with an example to execute log off when textcheck fails.
Depends upon your language choice.
Assuming you have the default language of C with your HTTP virtual user, then simply implement a logout function which contains your logout code. Call that function upon failure of your condition. A "return 1;" inside of that if/then conditional will also start a new iteration immediately. "return 0;" goes to a new iteration with respected pacing. "return -1;" kills the virtual user altogether.
I have an SSIS package with for each loop > sequence container. The sequence container is trying to read file from For each loop and process its data. The requirement was to not fail the entire package when any exception happened in processing a file but to continue processing the next file until all the files were processed from the for each loop. For this, I have set the Propagate variable for the sequence container to False. I have also added email step on On Error event of Sequence container. The package is running as expected and able to process all files even when any exception happened with any file. But I would like the status of my SSIS package to be failed finally since one of the files got failed. How can I achieve that ?
Did you try this options?
(SSIS version in russian on the left side but it's sequence container)
View -> Properties window -> Then click on your sequence container and it will show you ther properties of sequence container.
If i were you first of all i would try property "FailPackageOnFailture" - it should cover your question if i get it right.
P.S. Also you can see the whole properties of your project when you click on a free place in your project
UPDATED (after comments and more clear understanding task):
The idea is - set this param Maximum ErrorCount for SQ as max as you want - in this case it wont stop the package because 1 of the files was failed in SQ and next file will process, but it should stop package after SQ will finish his work because you don't change MaximumErrorCount for package.
Important - a value of zero sets the error count threshold to infinity and package or task never get's Failure
I am trying to send an alert if there is no records in destination table after copy activity is completed. right now I am try with lookup activity along with if activity but getting this below error
Operation on target Alert If no records in activity ts failed: The function 'int' was invoked with a parameter that is not valid. The value cannot be converted to the target type
You can do this more simple.
Add an variable to you pipeline, varError.
In your lookup, add a select count(*) from your_table
Add an activity "Set variable" where you set the variable to
#string(div(100, int(activity('IsRecordExist').output.firstrow.yourColumn)))
This will do an device by 0 if no values are copied, and cause the pipeline to fail.
You can then sett up a monitor for pipeline failed that sends you an alert.
I have a SQL job (4 steps job consist of SSIS packages) which runs on daily basis and extract data from various sources (source1, source2, source3) then it loads data to warehouse. Now my job fails due to 'Communication Link failure' with source1 at step 1.
Is there any way I can set up retry attempt SQL job based on this above error only.
For example, if I get error 'primary key violation' or some other data related issue then we should directly get notification that job failed but if we have error 'Communication Link failure' then step1 should do retry attempt.
Any suggestion would be appreciated.
Short answer: No, not with the SQL agent.
Longer answer: Maybe you can build up som logic where the package checks if the previous error was that specific error you're looking for, if then, execute again. Cumbersome but possible.
You can create an Event Handler for the OnError event with a Script Task which will check for this specific error and execute msdb.dbo.sp_start_job if this error occurred. Since I'm not sure the exact error code you're getting, this only checks the #[System::ErrorDescription] system variable for the specific text using the StringComparison.CurrentCultureIgnoreCase option to make this match case insensitive. However I would strongly recommend finding the exact error code and using the #[System::ErrorCode] variable to verify this instead. I'd also suggest only retrying the job a certain number of times or within a given time-frame to avoid excessive failures if this issue persists as well.
string errorMsg = Dts.Variables["System::ErrorDescription"].Value.ToString();
if (errorMsg.IndexOf("Communication Link failure", 0, StringComparison.CurrentCultureIgnoreCase) >= 0)
{
string connString = #"YourConnectionString;";
string startJobCmd = #"EXEC MSDB.DBO.SP_START_JOB N'NameOfJobToRetry;";
using (SqlConnection conn = new SqlConnection(connString))
{
SqlCommand sql = new SqlCommand(startJobCmd, conn);
conn.Open();
sql.ExecuteNonQuery();
}
}
I have a BPMN process with a sub-process within it. There are different flows leading to the sub-process. And I want to know, once inside the sub-process' execution, which flow has led to the current execution.
To this end I think variables could be handy. So I conducted a test in which I wrote a couple of scripts for flow's listener leading to the sup-process.
execution.setVariableLocal("V", "Expecting it to be local to the sub-process' execution");
But it turned out that execution points to the outer/parent process and thus the variable was set in parent scope.
So is there anyway to set an execution local variable from outside?
The simplest approach (basically use getVariable instead of getVariableLocal):
Add an execution listener to the take event of the sequence flows of interest
In the execution listener, perform
execution.setVariableLocal("flowTaken", execution.getCurrentTransitionId());
Access it in the sub process via
execution.getVariable("flowTaken");
If it has to be a local variable in the sub process:
Add an execution listener to the take event of the sequence flows of interest
In the execution listener, perform
execution.setVariableLocal("flowTaken", execution.getCurrentTransitionId());
In the BPMN 2.0 XML, define a variable input mapping for the subprocess:
<subProcess ...>
<extensionElements>
<camunda:inputOutput>
<camunda:inputParameter name="flowTakenAsSubprocessLocalVariable">${flowTaken}</camunda:inputParameter>
</camunda:inputOutput>
</extensionElements>
...
</subProcess>
