Checkpoint File Used By Another Process
Dec 5, 2006
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!

Hello,
I am DB Developer (not admin), excuse me if this is a silly question.
I don't know much about CHECKPOINT background But I feel, this process is slowing down performance of my sps which runs slower than normal in some cases.
Especially when I see any of my process goes in the suspended mode and its wait type is SLEEP_BPOOL_FLUSH and CHECKPOINTs process is also suspended and its wait type is CHECKPOINT_QUEUE.
More important anything else is... this background process (which I always find its spid is 11) BLOCKS all other user processes when it goes into suspended mode and its wait type is SLEEP_BPOOL_FLUSH
I dont know my analysis is correct (claiming checkpoint as culprit), need experts advice and help
can someone give info on checkpoint and how this effect server performance

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 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

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

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.

Hello all,
I am running into an interesting scenario on my desktop. I'm running developer edition on Windows XP Professional (9.00.3042.00 SP2 Developer Edition). OS is autopatched via corporate policy and I saw some patches go in last week. This machine is also a hand-me-down so I don't have a clean install of the databases on the machine but I am local admin.
So, starting last week after a forced remote reboot (also a policy) I noticed a few of the databases didn't start back up. I chalked it up to the hard shutdown and went along my merry way. Friday however I know I shut my machine down nicely and this morning when I booted up, I was in the same state I was last Wenesday. 7 of the 18 databases on my machine came up with
FCB:pen: Operating system error 32(The process cannot access the file because it is being used by another process.) occurred while creating or opening file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf'. Diagnose and correct the operating system error, and retry the operation.
and it also logs
FCB:pen failed: Could not open file C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataTest.mdf for file number 1. OS error: 32(The process cannot access the file because it is being used by another process.).
I've caught references to the auto close feature being a possible culprit, no dice as the databases in question are set to False. Recovery mode varies on the databases from Simple to Full. If I cycle the SQL Server service, whatever transient issue it was having with those files is gone.
As much as I'd love to disable the virus scanner, network security would not be amused. The data and log files appear to have the same permissions as unaffected database files. Nothing's set to read only or archive as I've caught on other forums as possible gremlins. I have sufficient disk space and the databases are set for unrestricted growth.
Any thoughts on what I could look at? If it was everything coming up in RECOVERY_PENDING it's make more sense to me than a hit or miss type of thing I'm experiencing now.

Hi I am using VWD 2008, SQL Express 2005, Reporting Services, Win-XP, IIS5Basically let's say I have 2 pages:Page1: has a SQLDataSource control that populates a GridView from a table from a database file myDB.mdf (no code behind)Page2: has a reportviewer control that show a report with data from the same table from myDB.mdf from the reportserver, (no code behind)I have attached myDB.mdf to the SQL Server Express using the SQL Server Management Studio Express.If I first open Page2 to display the ReportViewer it works ok. or using the Report ManagerNow this is the problem:If after that I try to open Page1 then a get an error message:Cannot open user default database. Login failed.Login failed for user 'myServerASPNET'. Exception Details: System.Data.SqlClient.SqlException: Cannot open user default database. Login failed.Login failed for user 'myServerASPNET'.Then I have to restart the SQL Server to fix it,Now I can open Page1 ok, but if after this I try to open Page2 (ReportViewer) againThen I get this error:" An error has occurred during report processing. o Cannot create a connection to data source 'my_Datasource'. &And this error if open the report using the report manager:" An error has occurred during report processing. o Cannot create a connection to data source 'my_Datasource'. § Unable to open the physical file "C:InetpubwwwrootWebsiteApp_DatamyDB.mdf". Operating system error 32: "32(The process cannot access the file because it is being used by another process.)". &Now if i check the Management Studio Express again, you can see that myDB.mdf was detached. It seems to be there by it has no Tables or definitions, so I have to attach it again..Do you know how to fix this?Thanks in advance,Ed

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,
Nicolas

Hi,
I'm trying to upload the ASPNETDB.MDF file to a hosting server via FTP, and everytime when it was uploaded half way(40% or 50%)
I would get an error message saying:
"550 ASPNETDB.MDF: The process cannot access the file because it is being used by another process"
and then the upload failed.
I'm using SQL Express. Does anybody know what's the cause?
Thanks a lot

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 have a File System Task Copy file operation to copy a file in an SSIS package. The package when scheduled as a job fails with the following error:
The process cannot access the file 'C:ETLConsignmentAppleAppleRawFile.txt' because it is being used by another process.".
However when I right click on the package and execute it manually from the Integration Services it runs successfully without any problem. I am not certain on how to resolve this issue any inputs will be much appreciated.
Thanks,

Error: 0xC002F304 at Rename file 1, File System Task: An error occurred with the following error message: "The process cannot access the file because it is being used by another process.".
When running two File System Tasks after each other, with the same file, the file is still locked when running the second task. Resulting in an error: 0xC002F304 at Rename file 1, File System Task: An error occurred with the following error message: "The process cannot access the file because it is being used by another process.".
I found a workaround by addind a Execute Process Task before the second File System Task that pings to the localhost. This results in a 5 second delay, but there must be a better solution. Anyone?

I need to write a process to get file size in kb and record count in a file. I was planning on writing a c# console app that takes the file path and name as a param however should i use a CLR?
I cant put a script in the ssis when it's bringing the file down because it has been deemed that we only use ssis for file consumption.

Unable to open the physical mdf file or log file because it is being used by another process
I am trying to write a Windows Application using ASP.NET 2.0, C#2005 EXPRESS, and SQL 2005 EXPRESS.
I had followed the introductory video to create a connection to the Database using Windows Authentication, and use the wizard to create a dataset and checking all the tables in the database.
After that I dragged a table from the data source created from the above process. The Details Grid so created is able to perform update, delete and addition of records.
But when I went back to the database at my PC I wasn€™t able to connect to the database. And if I opened the database first and then load the windows application and perform some database operations and went back to the physical database I wasn€™t able to open the tables in the database.
The error message is that the physical database connection cannot open the .mdf file or log file because another process is using the database. I guess it refers to the Windows Application.
Is this normal? Will it have any implications after the application is deployed? I suppose that there isn€™t a scenario where a Windows application and a physical process will access the database at the same time.
Will appreciate some feedback and advice on this scenario and whether it is a problem.
Thanks and regards

I am wondering how easy is to check for file locks and have our SSIS Package to wait until file has been release by the process which is using it.
Also, same question when we're writing to a Flat File (or Flat File Destination).

I am using a File System Task to delete the contents of a directory however there may be cases where a process is still using one of the files. What I want to do in these instances is to wait for a period of time and then retry the deletion.
Does anyone know of an easy way to implement this?

OK, I just want to know if I can use SSIS to open one text file create a table with the info in
SQL Server. Then open another fixed length file and insert rows in this table. I want to do this from an application in .Net. for e.g. I have a file that says "Col1 String 20, Col2 String 20,". This will create a table "Table1" in database DB1. then it will open a text file that has 200 rows for Col1 and Col2 with fixed length as 20. The table will be filled with the rows in the second text file. I want to give the user the ability to select the above files and when he clicks submit, the table will be filled. Is it possible?

I'm using Visual Web Developer 2005 Express, SQL Server 2005 and using the local file system as opposed to IIS for development purposes.
I will reference two pages of my site: one that manages Types of Tours and one that downloads a Tour Registration Excel file.
On the Tour Types page, there is a sqldatasource that populates a DetailsView whose default mode is Insert. On that same page I have a GridView that is populated from the same sqldatasource. The gridview has Paging, Editing and Deleting enabled. There is no code behind on this page except for a prompt to the user to confirm the delete action if he has elected to delete a Tour Type. This page works fine no problems.
On the download page, I have a prompt that allows the user to click a button to download the Tour Registration Excel file. The code behind opens the Registration table in the ASPNETDB.mdf database, builds an .xls file via a streamwriter and prompts the user to download the file.
My problem: if I start up VWD, go into my project, go straight to the download page without accessing any other pages, the download page works fine. If I access any other pages first and then go to the download page, I get the error "System.Data.SqlClient.SqlException: Unable to open the physical file "C:....App_DataASPNETDB.MDF". Operating system error 32: "32(The process cannot access the file because it is being used by another process." My simplified code behind is this:
Dim sw As System.IO.StreamWriterDim myConn As Data.SqlClient.SqlConnection, query As String, myCommand As Data.SqlClient.SqlCommandDim myReader As Data.SqlClient.SqlDataReaderDim fileName As String, baseDirectory As String, fullFileName As String
fullFileName = baseDirectory & fileNamesw = New IO.StreamWriter(fullFileName)myConn = New Data.SqlClient.SqlConnection("Persist Security Info=False;Integrated Security=true;AttachDbFileName=C:<pathnamehere>App_DataASPNETDB.mdf;database=ASPNET;Data Source=.SQLEXPRESS")query = "SELECT Registrations.RegistrationNum, Registrations.Title, Registrations.LastName, Registrations.FirstName, Registrations.Organization, Registrations.StreetAddr1, Registrations.StreetAddr2, Registrations.City, Registrations.State, Registrations.Zip, Registrations.WorkPhone, Registrations.HomePhone, Registrations.CellPhone, Registrations.email, Registrations.AddToMailingList, Registrations.NumberInParty, Registrations.Comments, Registrations.DateRegistered, Registrations.TourDate, Registrations.TourFormattedTime, TourTypes.TourTypeDescr FROM Registrations INNER JOIN TourTypes ON Registrations.TourTypeNum = TourTypes.TourTypeNum"

I occasionally receive the following error on backups to a disk backup device.
BackupDiskFile::CreateMedia: Backup device 'F:MSSQLBACKUPFull_Backup.BAK' failed to create. Operating system error = 32(The process cannot access the file because it is being used by another process.).
There are no other jobs running that access this file during the backup. So nothing else should be trying to touch the backup file.
Rerunning the backup again seems to work so it does sound like something is accessing the backup file, I just can't figure out what.
The backup proc reinitializes the backup file each time it runs with the init parameter and then appends remaining backups with noinit. This error occurs on several different servers. Could there be a problem reinitializing the same backup device? It seems like a previous backup has not let go of the device.
I am running SQL 2000 SP2 on Windows 2000 SP2.
Any ideas?

I have a SSIS package with the last three tasks in the control flow are stopping the SSAS, then "on success" the second last task is execute a batch file to copy a bunch of files to a remote server using the robocopy command, then "on success" the last task is to start the SSAS. I test all three tasks individually and they are all working fine. The problem is in-between the second last task and the last task, the second last task is to execute a batch file and then forward to the last task. The task just moved to the last task once the batch file is executed and it did not wait until the actual robocopy job is completed. Therefore it caused a problem in the robocopy process. Thanks.
