CheckPoints And On Completion
Jun 14, 2007
I have a package that has 4 Script Tasks that are placed sequentially.
I have Task1--> Task2-->Task3-->Task4
The arrows between them are OnCompletion Arrows as opposed to the Standard OnSuccess arrows.Even if Task2 failed, it would still execute 3 and 4
the catch is that i want it such that when i run the first time and task 2 fails, then all the tasks except task2 should run which is fine, but when i rerun it. I want it such that it realises that task 2 had failed earlier, so it runs just task2.... if both 2 and 4 had failed then it should just run 2 and 4
i tired to implement it with check points, but the problemn is that if it fails at task2 it stops at task2 and does not continue to execute tasks 3 &4... when u rerun it starts at 2 but like i said i would like 3 & 4 to have completed the previous run...
Any suggestions would be helpful
Thanks for any help in advance..

I want to use a checkpoint in an SSIS package and would require some help.
I have a scenario like this
Task A ------ Task B-----------Task C
------- Task B1
Task A has a precedence constraint which determines if either Task B or Task B1 runs. Task B is run if the condition is met and Task B1 if the condition is not met.
I would like Task B1 to be a script task that is used to fail Task A so that when the package is restarted it will start from task A based on the checkpoint.
Is there any way to do this ?

I have a package that uses ssis checkpoints. It works well. However, when I try to setup transactions for some task, the chekpoints aren't used.
I read BOL and It states:
"If a package is configured to use checkpoints, Integration Services captures the restart point in the checkpoint file. The type of container that fails and the implementation of features such as transactions affect the restart point that is recorded in the checkpoint file."
But, how checkpoints are affected by transactions? what relation exists between this two components?

hi people, i have crashed on a this problem. I have a sequence container and on this container I have set "FailPackageOnFailure=true". Now in this container there are 2 tasks. The first one is preceeding the second one. Now both this task have set "FailParentOnFailure=true". Both task are the same and their purpose is to drop table A.
1) I run the package and it fails, because there is no table to drop.
2) I create the table manualy and run package again.
3) I see, that the first task is beeing just SIMPLE OMMITED and the second task runs
In general, everytime any task in a sequence container invokes failure, next time is beeing ommited regardelss of its status. How can this be fixed ? Thanks

I am building a set of packages to load different things, some of which have relationships with the others. Therefore I want them loaded in a certain order. I have built a main package that executes the set of packages to control the flow of the packages.
Now, I want to implement checkpoints. Ultimately, I only want to deal with the main package that controls everything. So I figure the main package needs checkpoints enabled. When packages are nested and checkpoints are on at the top level package, will the nested package(s) start at the control flow point of failure or will it run the entire nested package? Should checkpoints be implemented within the nested packages as well? Should checkpoints only be implemented within the nested packages? Again, remember that I only want to launch
estart the main package.
Thanks. Any insight would be appreciated.

Hello everyone, I had been studying the relationship between SSIS Checkpoints and SSIS Transactions.
What I want to do is to create a package with different task, where each one task creates a new transaction, and the same time each task be a checkpoint, it€™s in order to restarts the package from the failure task not from the beginning.
The Transaction-Checkpoint solution contains two packages*:
CkeckpointsAndTransactions1.dtsx and CkeckpointsAndTransactions2.dtsx
Package CkeckpointsAndTransactions1 contains four tasks, task three always fail. The package is configured to use checkpoints and each individual task creates a checkpoint. Additionally, each task creates a new transaction. The package has the TransactionOption setting to NoSupported.
In the CkeckpointsAndTransactions1 package there is something wrong, when the third task fails and I restart the package, the package starts from the beginning, this is wrong!!, the package should restart from the failure task.
In order to the package works like is expected it€™s necessary to add a new task between second and third task. It is also necessary that this new task hasn€™t transaction support. This is shown in the CkeckpointsAndTransactions2 package, in this package after package failure, I restart the package and the package restarts from the failure task, like is expected, but the additional task should not be necessary!!
Does anyone what is wrong in my packages?? How can I to create a package with different task, where each task creates a new transaction, and the same time each task be a checkpoint?
*Please download the BIDS solution from hernan93.files-upload.com (Transaction-Checkpoint.zip file)

Hi there,
I am trying here to get a situation going which includes both transactions and checkpoints to make sure that when something goes wrong I don't get a) data corruption (hence the transactions and b) I don't have to completely restart my 2hr run (hence the checkpoints). However I ran into something of which i cannot see whether it is intended behaviour or simply a bug.
Here's the deal:
I have a SSIS-package in which I enable checkpoints (CheckpointUsage: IfExists and SaveCheckpoints: True).
I have 2 Dataflows which follow eachother (the first dataflow prepares data for the second dataflow to edit).
Because I want to make sure that my data is secure I put a separate transaction on both the dataflows.
And here my problem arises. If I run my package now and the second dataflow breaks then my checkpoint sends me back to the first dataflow and my initial insert is executed again, which isn't meant to happen (I enabled checkpoints to prevent rerunning items). Somehow my checkpoint does not register the fact that the first dataflow has already been executed and it will execute that one again upon rerun.
However: if I put a random task between the 2 transacted dataflows (for example an empty script-task) it will work as intended. Just as long as this inserted item doesnt have a transaction; because if it does then the problem comes back
Now if I execute the package then my checkpoint shows that the first dataflow has already been executed and thus it will not execute this one again and it starts at the second dataflow upon re-execution.
I can work around it (with the empty script-task) but still I am wondering as to why this is happening. I am very interested to hear whether this is really a bug or if it is intended behaviour (and if it is then why is it intended?)

Hi,
I am using check point in my packages , but i am not able to run my packages where it exactly got failed. The scenario is i am 100 rows at source system and i was loaded 95 records into target and due to the some data formatting issues i got failed at the 96th record. Later i am trying to re-execute the package, Surprisingly my package start run from the 1 st record(nothing but the start point of dataflow task).
How can i achive to run from where it excatly got failed(96th record) ?? is it possible using check points else is there any work-around approach ??please respond this post , it is very helpfull for me..
TQ

I have a package that has a container containing multiple DF Tasks.
The container is set to be Transacted, such that should any of the DF tasks fail the data inserted in any of the previous tasks rolls back.
This works as expected.
However, this container is part of a larger package and so I wanted to have a checkpoint on it, so that should any of the tasks within it fail, the package could be restarted from this container.
However, I would expect the functionality to be that on failure, the checkpoint would cause the whole container to be started again (because the container is transacted all DF task info would be rolled back) so we would expect it to start at task 1 again.
This is not the functionality I see. The package restarts from the failed task within the container every time.
According to the book Prof SSIS, it should start again from the first task and as explained this makes sense on a Transacted container as you would want this to happen.
A previous forum message encountered the same issue it appears:
See SSIS Checkpoints 04 Dec 2006.
This is an extract from it:
"I only experimented a little but my experience was that when I have a transacted container with multiple tasks that are checkpointed, SSIS would try to restart from the task that failed rather than from the first task in the container. The transaction was being rolled back correctly though.
In short, I felt that check points were not aware of transactions.
So, I ended up with this setting and it works for me:
Container is checkpointed and trasacted.
Tasks within the container are not checkpointed.
'FailParentOnFailure' property set to True on the tasks.
That way, if a task failed, it would fail the container and a checkpoint would be created at that level. Transaction would be rolled back as usual."
While this makes sense to me it is not the same properties that the SSIS book has that work.
Additionally, this didn't work for me either !!
I have tried every combination of FailPackageOnProperty and FailParentOnProperty that makes sense but every time the package restarts from the failed container within the task.
The transaction is rolled back correctly every time, but it seems the checkpoint that is created is not used correctly when dealing with transactions within containers.

Hi,
We are currently facing an issue in ensuring restartability of an SSIS package. The scenario is explained below.
Context:
The SSIS Package has two Data Flow tasks. The Data Flow task named DFT1 is the predecessor for DFT2 and chained with OnSuccess precedence constraint.
OnPreExecute and OnPostExecute event handlers have been implemented for DFT1. Each task in both event handlers as well as DFT1 and DFT2 have FailPackageOnFailure set to True.
Scenario1: Task in OnPreExecute of DFT1 fails.
DFT1 is attempted and succeeded.
OnPostExecute of DFT1 was not attempted.
DFT2 was not attempted.
Checkpoint file was created; however, no entries were made.
When restarted, execution started from first step in Control flow.
Scenario2: Task in OnPostExecute of DFT1 fails.
DFT1 and its OnPreExecute Event were executed.
DFT2 was not attempted.
Checkpoint file was created and entries were made. Entries had DTS:result as 0 for OnPreExecute and DFT1 tasks.
When restarted, DFT2 was executed. OnPostExecute event, which failed during previous execution, was not attempted.
Each task in the package, whether it is in Control flow or as part of an event handler is crucial for seamless execution. But apparently, as explained above, there is no reliability on the event handlers in case of failures. Has anyone encountered similar scenario? Is this behavior as per design of the runtime engine?
Thanks, in advance,
Regards,
Rajesh

Hi,
I have a master package with a sequence container with around 10 execute package tasks (for child packages), all in parallel. Checkpoints has been enabled in the master package. For the execute package tasks FailParentOnFailure is set to true and for the sequence container FailPackageOnFailure is set to true.
The problem i am facing is as follows. One of the parallel tasks fails and at the time of failure some of the parallel tasks (say set S1) are completed succesfully and few are still in execution (say set S2) which eventually complete successfully. The container fails after all the tasks complete execution and fails the package. When the package is restarted the task which failed is not executed, but the tasks in set S2 are executed.
If FailPackageOnFailure is set to true and whatever be the FailParentOnFailure value for the execute package task, in case of restart the failed package is executed but the tasks in set S2 are also executed.
Please let me know if there is any setting that only the failed task executes on restart.
Thanks in advance

Hi,
I have a FTP task in my control flow that download files from a FTP server. This ftp task is inside a foreach container that loops over a ADO recordset for the file name. The files that the ftp task pulls are huge. If the FTP task fails then I want the FTP task to restart and only download those files that have not been downloaded. Is this possible?
What possible configurations do I have to make to the foreach container and the filetask?
Thanks a lot in advance for your help and time.

Hi All,I have a DTS package that runs calling a few stored procedures and anactiveX module. The package does some data cleanup and load. It takesan hour to complete. I have emails sent at the beginning and end ofthe package execution along with error notifications if any of thestep fails.The issue is that, the DTS runs successfully. I ran the package fromthe server and it completes. If I schedule it, it has been running forover a few months without any issues. One fine day hell broke looseand it started to give an attitude!!When the job is invoked automatically on the scheduled time, it runsthe package. Does what its supposed to do including sending out thefinal email. but is not finishing the job. The job says its stillexecuting but the final step has completed. I have tried logging thepackage, and it says completed the last step.. But the JOB Log hasn'twritten anything to the log file.. (Job Log is where I am logging thestep where I am calling the DTS).Has anyone have any idea what this issue is? I am at a dead end andhave no clue why this is happening. I am thinking of changing thewhole process but before that I want to try posting this.Any ideas, suggestions will be much appreciated. Please feel free tolet me know if there is any additional information you need in orderto troubleshoot this issue.Thanks in advance..Aravin.

I have three sequence containers setup to run in parallel. I have a final step that parses the log file and displays results, and I want to this to occur when all three containers have completed, success or failure. I therefore have a constraint from each container that feeds into my final step, and all three constraint types are set to "completion".
When I run the package and one of the tasks within a container fails (and fails its parent, but not the package) the final step is not executed.
If I take off all the constraints except one, the final step is executed as expected.
I am using checkpointing if that has any impact. Disabling it makes no difference.
Any thoughts/alternatives I might try?
thanks

I'm not entirely sure this is the place for it but I need to implement an automatic text completion function.
I'd like to know if there is something, such as a built-in function, that could help me.
The best idea I have is to create some sort of node tree and work with that but there has to be a better way.
I need to do it in C# or in MS SQL. Any kind of help is much appreciated!

Is there a way (during the Control Flow) to force a package to complete successfully when a specific condition is met?
Here is what I'm trying to do:
A package will be scheduled to execute once a day
The first thing it does is downloads Excel files from an FTP site.
If there are no files to download, I don't want the package to fail, I simply want the package to stop (preventing the subsequent Data Flow tasks from executing), returning a successful completion.
The reason, I need a successful completion is because I plan to have MOM monitor the Windows event logs, notifying us of any errors that this package logs.

Hello All,I have a stored procedure which will act like a main/controller scriptwhich will then invoke more stored procedures (~20). Basically, itlooks something like below:-- start scriptcreate procedure ...print 'process started'exec sp_1exec sp_2exec sp_3....print 'process ended'-- end scriptLooking at it, after running that procedure, immediately I would expectthe first PRINT statement to be printed but it won't. It seemedthat the print statements would only display the messages afterthe whole processing completed.What's the reason for this sort of behaviour. If so, then we wouldnot be able to print any progress reporting in our scripts.Please comment.Thanks in advance.

Hi,
I'm working on an application that involves various components two of which are an SSIS package and a C# windows service.
The SSIS package imports data from a number of structured flat files into database tables and then runs a number of stored procedures that rearrange/normalize the data and perform certain calculations the results of which are also stored in the database. The package will run at regular intervals as new data structured flat files become available.
The C# windows service is a caching server and the data it needs to cache is the results of the stored procedures run by the SSIS package. I'm therefore looking for a way to notify the C# app when the SSIS package has completed.
I've looked at Sql Servers Query Notification but, if i've understood correctly, that seems to depend on the client code issuing a SQL statement and attaching a sqldependency object that will check for changes to the resultset of the particular query which is not really what i'm after.
I've considered SSIS events but again i think for a C# app to monitor SSIS events the package needs to have been executed from within the C# app. If there's a way for the SSIS package, running completely independently of the C# process, to fire an event that the C# windows service can subscribe to then that would be ideal.
I don't know whether other options like Sql Server Notification Services or even something quite crude like writing a flag to a flat file that the C# service can read would be more ideal?
Thanks

Hello,I have several SQL Server jobs that execute procedures written to rundeletes and updates against tables in my data warehouse. Some jobsoccasionally get stuck with the status "Performing Completion Actions"and can only be reset by restarting SQL Server or rebooting theserver.I have seen one answer to this problem in a DTS package is to checkthe box specifying "Close Connection on Completion" for each task. Isthis the equivalent of setting "cursor_close_on_commit" to "on" inT-SQL?? If not, what is the equivalent in T-SQL??Thanks in advance!Cliff

How to calculate estimated completion time of a job and what is the variance/difference in time based on previous job history. Looking for tsql query which can accomplish this.For example)...Daily a job is taking 10 mins to complete. However, today due to some reason, the job is running over an hour and still running. It could be a blocking issue or some performance issue on the server due to which the job is still running.
In such cases, using a tsql query or a stored proc which monitor these jobs every 3 mins (Configurable value), so every 3 mins , query has to check, if they are any jobs which are taking more time than its usual completion time/avg completion time in that case shoot an email using dbmail functionality i.e. sp_Senddbmail .. From there, DBA can dig further using waits or sql trace etc...

Hi,
I have a simple web application which calls a stored procedure. The stored procedure operates as a transaction and runs for several minutes. I've created a partial class to set the SQLcommand timeout property to avoid any timeouts, which works fine. Unfortunately though, when the application is run in the production environment, it ends in an error after a certain amount of time (maybe a couple of minutes - not exactly sure), which seems to be the same each run. It doesn't appear to end the stored procedure though, which results in locking the tables. It runs fine in the development environment, and it doesn't appear as though any error information is provided when the application crashes.
I'm assuming that the ASP.NET application is timing out for some reason, but the stored procedure itself is fine. I can run it directly from SQL server without any dramas. In the Virtual Directory configuration within IIS, I have the script timeout period set to 1200 seconds. The Default Web-Site timeout property is set to 120 seconds, but I'm assuming that this is only for internet connection timeout, not database transaction timeouts.
Any information as to what may be causing this is appreciated.
Thanks

I have a job which is scheduled to run once daily. The job is enabled and the schedule is also enabled. After the job runs (successfully), the schedule has its 'Enabled' flag reset (i.e. the 'Enabled' checkbox in the schedule properties has become unchecked) and so is not rescheduled.
I have other jobs configured in a similar way, but they are run and then rescheduled in the normal way without any problems.
What could be going on?
