Execute A Task Even Though A Checkpoint File Says It Has Already Been Executed
Dec 16, 2005
I have the following scenario:
-I have a package that uses checkpoints
-The first task in that package (an Exec SQL Task) retrieves a timestamp value from an external source
-That timestamp value is used in data-flows to pull data that has been changed since then
-At the end of the package the value in the db is updated
Now...if something fails then on the next execution the checkpoint file will kick in. But this means that the first task (which retrieves the timestamp) will not execute and therefore all the data-flows will be pulling the wrong data.
The only way I can think of getting around this problem is to specify that a task should execute regardless of the presence of a checkpoint file. Unfortunately it seems this cannot be done.
Another option might be to put an OnPreExecute task on the package that gets the timestamp value.
Anyone got any advice about how I should progress? Short of a suggestion from elsewhere I'm going to go with the tactic of using the OnPreExecute to retrieve the timestamp.
Thanks in advance.

I have a situation where I need to make sure a task executes regardless of whether the package starts from a checkpoint or not. Is this possible?
Here's the scenario:
I have a package with 3 tasks {TaskA, TaskB, TaskC} that execute serially using OnSuccess precedence constraints.
The package is setup to use checkpoints so that if a task fails the package will restart from that failed task
TaskA is insignificant here.
TaskB fetches some data and puts it in a raw file
TaskC inserts that raw file data into a table.
Problem is that the insertion violates an integrity constraint in the database - so it fails. The problem is easily fixed but it needs to be fixed in TaskB because that is where the data is sourced.
So, I need to be able to execute TaskB again, even though it was TaskC that failed. Currently the package restarts from TaskC which reuses the raw file (which has the bad data in it) so the package continues to fail even though the cause of the problem has been fixed.
How do I configure the package in order to execute TaskB again? Is it even possible?
Regards

I'm having a hard time to getting back an xml data back from a stored procedure executed by an Execute SQL task.
I'm passing in an XML data as a parameter and getting back resulting XML data as a parameter. The Execute SQL task is using ADO connection to do this job. The two parameters(in/out) are type of "string" and mapped as string.
When I execute the task, I get the following error message.
[Execute SQL Task] Error: Executing the query "dbo.PromissorPLEDataUpload" failed with the following error: "The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 2 ("@LogXML"): Data type 0xE7 has an invalid data length or metadata length.". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
I also tried mapping the parameter as XML type, but that didn't work either.
If anyone knows what's going on or how to fix this problem please let me know. All I want to do is save returning XML data in the parameter to a local package variable.
Thanks

In the Control flow tab, I have an Execute SQL Task that outputs full Result set into a variable of an object type. Now how can I write the contents of the Full Result Set into a text file using Script Task. I also want to format the following way while I output into a file:
Column Name 1 : Column Value
Column Name 2: Column Value and so on
I tried writing the contents of the Object Variable into a file, but the file had an output of single word: System.__ComObject.
Code for Writing the Full Result Set into a Text File
Dim RSsqloutput as String = Dts.Variables("objVariable").Value.ToString
Dim strVal as String = "File completed on " & Now() & vbCrLf & "------------------------------------------------------" & vbCrLf
oLogFile.WriteAllText("C:MyFile.txt", strValue)
oLogFile.WriteAllText("C:MyFile.txt", rsSQLOutput)
I went through this link that explains how to write XML Result Set into a File, But this doesn't help as it writes in XML format.
Would you please give me a hint of code how I can go upon.

hi,
i have designed DTS packages, I have a script component that picks up the 'Path' of a file stored.
The Path is a column in database and that obtained from OLEDB source.
now i need to zip the files in the path given above and than store it in some location. How do I do that?

I have a remote batch file on machine B that I need to execute using 'Execute process task' control from a package on machine A. The batch file uses pgp software and encrypts a file sitting on machine B itself. The reason why my batch file is sitting on machine B, is because the PGP software is on machine B.
If I execute the batch file by itself from machine B, the script runs fine. I refer the same batch file as a UNC path from my package on machine A. But that does not work since the 'Working directory' is still machine A. I can not set machine B's folder as the working dir because it does not accept UNC path. So I say, ok , let me map a path to that UNC location and map it as drive 'Z:'. Certainly if I do so, I will be running the process on machine A and the batch file will look for the pgp software on machine A, and hence fail.
I have tried third party remote batch execution tools (PSEXEC) but have not had success, not because of SSIS limitations, but simply because the PGP executable when run through the PSEXEC tool, does not identify the location of the public keys on machine B and hence gives an encrytion failure.
How do I get the remote batch file to execute such that it executes with its own env? Is there a better remote execution tool I can try or are there any other features of SSIS I can use to get around this issue? I need the results of the batch file and hence do not want to make it an asyncronous process.
Thanks
Sumeet

SELECT from openrowset(BULKÂ 'SERVERNAMEsomepathsomefile.csv'... fails while SELECT from openrowset(BULK 'c:somepathsomefile.csv' ... works.
I am running the task as a specific sql server user. If I run the same query in management studio using execute as login='batchuser', it also works for any path.
How can I make this work without an extra step moving the data to the local server? Because that would cause extra administration.

I am new to this, but have scoured the web and not found an answer to my question...
I have an execute process task that runs a simple batch file. When this batch file completes with an ERRORLEVEL greater than 0, I would like the task to fail. I thought this simply meant setting the "FailTaskIfReturnCodeIsNotSuccessValue" property to true, and setting the SuccessValue to 0. However, this does not appear to work.
Even with a simple batch file forcing the errorcode to 1 as follows, the task still completes "successfully".
SET ERRORLEVEL = 1
Any ideas? Thanks!

I'm trying to use "findstr.exe" to extract some lines of interest from a data file, which I will later load to a table. I'd like to issue this form of a command:
findstr.exe "^SEARCHSTRING" "srcfile" > "dstfile"
I build the arguments using expressions, and both the search string and source file get correctly set. However, the ">" seems to be ignored--I can see the lines spitting out to the temporary window when I run under VS.
QUESTION: how do you redirect the output of a command run under an Execute Process Task?

There are two options to specify the subpackage location (SQL Server or file location). I'd like to know how I can specify a variable name that points to the file location so I avoid hard coding the file location which could change during production installation.

OK. I give up and need help. Hopefully it's something minor ...
I have a dataflow which returns email addresses to a recordset.
I pass this recordset into a ForEachLoop configuring the enumerator as (Foreach ADO Enumerator). I also map the email address as a variable with index 0.
I then have a Execute SQL task which receives this email address as a varchar variable (parameter 0) which I then use in my SQL command to limit the rows returned. I have commented out the where clause and returned all rows regardless of email address to try to troubleshoot this problem. In either event, I then use a resultset to store the query result of type object and result name 0.
I then pass this resultset into a script variable to start parsing the sql rows returned as type object. ( I assume this is the correct way to do this from other prior posts ...).
The script appears to throw an exception at the following line. I assume it's because I'm either not passing in the values properly or the query doesn't return anything. However, I am certain the query works as it executes just fine at the command prompt.
Try
ds = CType(Dts.Variables("VP_EMAIL_RESULTS_RS").Value, DataSet)
My intent is to email the query results to each email address with the following type of data by passing the parsed data from the script to a send mail task. Email works fine and sends out messages but the content is empty. I pass the parsed data as string values to the messagesource and define the messagesourcetype as a variable in the mail task.
part number leadtime
x 5
y 9
....
Does anyone have any idea what I might be doing wrong?
thanks
John

I've all procedures running over EXECUTE permission. They're running properly without the SELECT or DRY permissions on involved tables.
But some procedures of above cited, in a particular tables or particular the procedure don't runs properly with out enabling SELECT permission on involved tables.
The EXECUTE permision runs overs other permissions on tables if the're not implicit denied, it's the best segurity practice. Then what is happen?? why need extra SELECT permision on some tables ?. The usser, and function role are ok.
You troube the same, some help please :)

I have a package with settings SaveCheckpoints=True and CheckpointUsage = Never. After the package failed I fixed the cause of failure by setting a database column to allow nulls. Then I went to our web app that we built to monitor package execution and clicked on the button to restart the package. The web app loads the package and then sets the CheckpointUsage property of the package object to 'Always'. Then it executes the package in a new thread. The package then produced this error:
Checkpoint file "E:Package1Checkpoint" failed to open due to error 0x80070005 "Access is denied.".
Since there was only one remaining task to run in the package I ran it manually.
Now here is the really interesting part. I then needed to run the same package but with different parameters. When I attempted to run it with the saved checkpoint settings (CheckpointUsage=Never, SaveCheckpoints=True) I got this error:
"An existing checkpoint file is found with contents that do not appear to be for this package, so the file cannot be overwritten to start saving new checkpoints. Remove the existing checkpoint file and try again. This error occurs when a checkpoint file exists, the package is set to not use a checkpoint file, but to save checkpoints. The existing checkpoint file will not be overwritten. "
So I then attempted to rename the checkpoint file so it would not interfere, however, it would not let me, saying that the file was in use.
So what I had to do was add a configuration entry which set SaveCheckpoints to False. Then I was able to run the package.
Any ideas?

I have an SSIS solution with 8 packages in it. I have checkpoint turned on with the 'If Exists' option. Each of the 8 packages have 8 separate checkpoint files specified.
One out of two runs will fail with one of the below errors:
The checkpoint file \xxxxxxxx is locked by another process. This may occur if another instance of this package is currently executing.
Checkpoint file \xxxxxxxx failed to open due to error 0x80070020 "The process cannot access the file because it is being used by another proces
I have checked all the settings and everything looks fine, looks like the problem is when you have many Control Flow tasks in a package and if two of them are completed at the same time and they try to write to this file one of them is unable to write and it fails.
This is causing the entire job to fail even though the control flow was successful.
Anyone encounter this issue? Any assistance is appreciated.
Thanks!

I have the failed path of many tasks pointing to a single Script Task that logs a failed entry into my database. In this script task, I need to be able to determine the task that faliled as I need to write a unique error message depending on the task that failed.
In my VB script, how would I determine which task was the one that failed?
Thank You!!!

I have modified my workflow to take conditional branch. The workflow terminates after the branched tasks finish without continueing to the next task no matter how I set the flow out condition. I found I have this problem when a task take more than one input. Does SSIS has a seeting for limiting the inputs to be taken?
Thanks in advance for the help!

Hi,
I have a problem where my packahe isn't restarting from the point of failure and I'm tryig to understand why not.
The following line came from the checkpoint file:
<DTS:Container DTS:ContID="{36A685E1-049A-4E6C-9884-AADF8BE29577}" DTS:Result="0" DTS:PrecedenceMap="" />
Can anyone explain:
What DTS:Result & DTS:PrecedenceMap are used for?
What values can DTS:Result contain and what do they mean? [Today I have only seen "0".]
What values can DTS:PrecedenceMap contain and what do they mean? [Today I have only seen "Y" & "".]
Thanks

hi folks,
i have this error when trying to run the package in development mode.
and i can not decipher this non-intuitive message:
Error: 0xC001604D at <package name>: Checkpoint file "" failed during creation due to error 0x80070003 "The system cannot find the path specified.".
please note that i have no checkpoints on package anymore; i had two but i deleted them but this message still appears.
i have searched the web but no luck in finding an answer.
maybe someone would be able to point out my obvious mistake here.
many thanks,

Dear all:
I had got the below error when I execute a DELETE SQL query in SSIS Execute SQL Task :
Error: 0xC002F210 at DelAFKO, Execute SQL Task: Executing the query "DELETE FROM [CQMS_SAP].[dbo].[AFKO]" failed with the following error: "The transaction log for database 'CQMS_SAP' is full. To find out why space in the log cannot be reused, see the log_reuse_wait_desc column in sys.databases". Possible failure reasons: Problems with the query, "ResultSet" property not set correctly, parameters not set correctly, or connection not established correctly.
But my disk has large as more than 6 GB space, and I query the log_reuse_wait_desc column in sys.databases which return value as "NOTHING".
So this confused me, any one has any experience on this?
Many thanks,
Tomorrow

I'm looking for a way to refer to a package variable within any
Transact-SQL code included in either an Execute SQL or Execute T-SQL
task. If this can be done, I need to know the technique to use -
whether it's something similar to a parameter placeholder question
mark or something else.
FYI - I've been able to successfully execute Transact-SQL statements
within the Execute SQL task, so I don't think the Execute T-SQL task
is even necessary for this purpose.

I can set the propperty of the checkpoint file to a local drive, but not to a UNC path mapping, mapping to my host server. (loop back)
Example: "I:FILEFILE1$InputArchiveOntwikkel " is possible as checkpoint file property.
S11487O$InputArchiveOntwikkel is not possible, though this is the same folder on the local host.
For data source both unc path and drive mapping are allowed. Why this difference?

I'm using SSIS in Visual Studio 2012. My Execute SQL Task calls a Stored Procedure where I have a TRY-CATCH. Last week there was a problem and the CATCH was executed and logged an error to my error table, but for some reason the Execute SQL Task didn't fail. Is there a setting to make the Execute SQL Task fail when an SP encounters a failure?

I am using SQL 2005 SSIS. I am joining several large tables and then the move result into another table in the same database.
I would like know which method is faster:
Use Execute SQL Task to insert the result set to the target table
Use the Data Flow Task to insert the result set to the target table. (Use OLE DB source to execute SQL command and then use the SQL destination)
Could you tell me why then other is slower?
Thanks.

Hi everyone,
For first time I'm testing this task and surprisingly, when I try "Edit Package" option:
1)The DTS host failed to load or save the package properly
2)The selected package cannot be opened
3)Error HRESULT E_FAIL has been returned from a call to a COM component
But after these messages you can see all the tasks but they haven't name!!
It seem as if RCW mechanism has failed between managed and unmanaged coded-partially.
I don't dare to follow doing more stuff, I don't know if that package is well-loaded or not from there. ?¿
Any guidance or idea about this?
