WMI Evnt Watcher Task Problem
Apr 6, 2007
I would like this task to watch for a particular text file in the particular folder.
here
Connection managers:
servename=\localhost
namespace=
ootcimv2
WMIQuerySourceTypeirectinput
WMIQuerySource:
SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE Targetinstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name="c:\\ImportData\\ est.txt""
Rest of the fields i leave as they are..
I get this error
[WMI Event Watcher Task] Error: Watching for the Wql query caused the following system exception: "Unparsable query.". Check the query for errors or WMI connection for access rights/permissions.
I am looking for test.txt on my local machine.

HI, I need to trigger some packages upon existance of specific files in a particular directory. Sound lkike the file watcher task (from SQLIS) would do the job but I am wondering what is the difference of using this tool instead of a for each loop container. I mean, If a file exists in a directory, the for each loop container will detect it. Since the file watcher is not a service, the package containing it needs to ne scheduled on a regular basis for the filewatcher to detect the file, right? So, a for each loop container would do the job? So, waht wouldbe the advantage of using the file watcher task?
Thank you,
Ccote

Installed File watcher task, then created a new SSIS package by adding the file watcher task in the control flow, below are my setting's inside the file watcher task editor:
2. Options
Filter - *.*
Find Existing Files - True
Timeout warning - False
3. Path
Path input type: Direct imput
Path - \server1Sourcefolder
Include subdirectories - False
Actually my understanding about this task is:
This file watcher task will constantly check for the file and then will execute the SSIS package.
If my understanding is correct, then where do we specify the name of the SSIS package?? And also do we need this SSIS package which has the File watcher task to run every 5 minutes or so, so that it can keep checking for the file existence.
Please help, thanks!!

In the file watcher task in the filter section does it look for exsiting file name which we have mentioned or is it possible to give first few letters of the file name like
pat*.txt
Please let me know

I want to watch a directory 24 hours a day to launch SSIS packages as files arrive. There are several options I have found to accomplish this:
Use the WMI Event Watcher task in SSIS to launch the packages as files arrive. Leave the package with the WMI Event Watcher task running all day long everyday
Create a Windows service that uses WMI to detect file arrival and launch packages
Schedule SQL Server Agent to run the package when a WMI event is raised
What is the best practice? Are there better approaches that I have not listed?

Hi All,
I have a problem in which I want the run an SSIS based on a file being dropped in a directory. I've tried the WMI event watcher as well as the File Task Watcher component. The problem that I'm seeing is that if the process is currently processing in the pipeline while another file dropped, the newly dropped file doesn't get picked up. Is there a way to create a FileWatcher Task in SSIS which will spawn a SSIS job and return immediately for watching files?

Hey there
Ive built an SSIS package which generates a file from a legacy system and then downloads the file into a designated folder on the server. I need the file watcher task to wait for a the file to completely finish loading before it says it is complete. Currently, as soon as the file is created, the WMI step finishes.
Any help would be greatly appreciated!
Kind Regards
David

I have been testing with the WMI Event Watcher Task, so that I can identify a change to a file.
The WQL is thus:
SELECT * FROM __InstanceModificationEvent within 30
WHERE targetinstance isa 'CIM_DataFile'
AND targetinstance.name = 'C:\Program Files\Microsoft SQL Server\MSSQL.1\MSSQL\Backup\AdventureWorks.bak'
This polls every 30 secs and in the SSIS Event (ActionAtEvent in the WMI Task is set to fire the SSIS Event) I have a simple script task that runs a message box).
My understanding is that the event polls every 30 s and if there is a change on the AdventureWorks.bak file then the event is triggered and the script task will run producing the message.
However, when I run the package the message is occurring every 30s, meaning the event is continually firing even though there has been NO change to the AdventureWorks.bak file.
Am I correct in my understanding of how this should work and if so why is the event firing when it should not ?

Hello,
I have to make a application using filesystemwatcher which watches the file on the remote server. If that file is changed then I have to fetch that file from ftp location to the server. I have made the SSIS job to fetch the file but not able to set a file system watcher on remote server that watches the file. If the file is changed then I need to insert a row in the SQL server database and then fetch the file.
I have made the application. the code is below:
private void Form1_Load(object sender, EventArgs e)
{
// Create a new FileSystemWatcher and set its properties
FileSystemWatcher watcher = new FileSystemWatcher();
watcher.Path = "C:\";
watcher.IncludeSubdirectories = true;
/* Watch for changes in LastAccess and LastWrite times, and the renaming of files or directories.*/
watcher.NotifyFilter = NotifyFilters.FileName | NotifyFilters.Attributes | NotifyFilters.LastAccess | NotifyFilters.LastWrite | NotifyFilters.Security | NotifyFilters.Size;
//watcher.WaitForChanged(WatcherChangeTypes.All );
// Add event handlers.
watcher.Changed += new FileSystemEventHandler(OnChanged);
watcher.Created += new FileSystemEventHandler(OnCreated);
watcher.Deleted += new FileSystemEventHandler(OnChanged);
watcher.Renamed += new RenamedEventHandler(OnRenamed);
watcher.EnableRaisingEvents = true;
}
public static void OnChanged(object source, FileSystemEventArgs e)
{
MessageBox.Show(e.FullPath + e.ChangeType.ToString("G") + "" );
}
public static void OnCreated(object source, FileSystemEventArgs e)
{
MessageBox.Show(e.FullPath + e.ChangeType + "");
}
public static void OnRenamed(Object source, RenamedEventArgs e)
{
MessageBox.Show(e.OldFullPath + e.FullPath + "" + e.OldName);
}
Now how can I give the ftp details such as IP address, User name and password in the above code.
Regards,
Deepesh Verma

I'm trying to use a WMI Event Watcher Task as a directory watcher. I know it is available from Konesans at http://www.sqlis.com/23.aspx but they don't feel obliged to make this open source yet. I definitely appreciate the contribution of the binary to the community.
I'm very interested in understanding how the event handler gets the path of the file that caused the event. I added a Script Task to the Event Handler tab and it fires as expected when I create a new file in the directory. I can retrieve the value of the SourceName which is just the name of my Event Watcher Task. I can't find documentation on an object model that is exposed through SSIS that would reveal the name or path of the file, although it's clear this information is available in direct WMI queries from code or a WSH script.
My only guess is that you need to do a workaround in Script (or a custom module) by querying the directory for the most recent file (or list of files compared to a list of processed files) rather than a synchronous feed of the path directly into the SSIS event handler. Ideally, you'd like to get one event per new file created, although this might not be deterministic with the way the OS fires these events and SSIS responds to them. So at the end of the day, querying the directory for recently created files may be the only reliable way of getting the (list of) new files.
I know that this can take hours and hours to figure out since you really need to understand how WMI interacts with SSIS but I would be indebted if you can shed some light on this for me and the community.
Thanks,
Norm

Hi,
I have implemented a WMI Event Watcher in my SSIS package which polls a directory at 5 second intervals for the presence of files.
I have noticed that at times this file watcher service doesn't seem to function. Yet if I stop and start the package it usually works again.
Everything is running locally, including the polled folder.
Has anyone experienced similiar issues, or may know the cause/fix of this problem?
Thanks.

Hi,
I have an SSIS Package to get the data from an Excel Source. For that I am using WMI Event Watcher to find when the file drops into a specific folder. It is working fine when I check any folders in the local machine.
We have a separate WebServer and Database Server for our application. The application is deployed in the Web server and the SSIS package is deployed in the Database server.
Since the files are dropped through application, it is dropped in the Webserver. I have mapped that drive in my Database Server and I am trying to link that folder in the SSIS package, but the event is not firing.
Please provide me some solution for this and revert for any clarifications.
Thanks & Regards,
Prakash Srinivasan

I am trying to watch for new files being created in a directory on a SQL server, using a WMI watcher. But I am getting a strange error in wbemess.log. The package runs, but does not detect files in the directory. There is no known anti virus software being run....
(Thu Nov 30 18:51:19 2006.799112375) : Unable to activate event filter with invalid class name 'HPQ_VT_STATUS_VIRUS_LIKE_ACTIVITY_IS_OCCURRING' (error 80041002). The filter is not active
(Thu Nov 30 18:51:19 2006.799112375) : Unable to activate event filter with invalid class name 'HPQ_VT_STATUS_VIRUS_LIKE_ACTIVITY_HAS_STOPPED' (error 80041002). The filter is not active
The expression I am using is correct, because I get a parsing error and the package fails to run if the correct number of backslashes are not in the right place. Below are two that I have tried.SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA 'CIM_DataFile' AND TargetInstance.Drive='C:' AND TargetInstance.Path='\\work\\ssis\'
SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name="c:\\work\\ssis""
Anyone seen this before or have any useful suggestions? The server is an HP Proliant, could that be linked to the HPQ_?

Hi,
I am using a WMI Event Watcher task to watch for files dropped into a directory over a network drive.
It seems to work fine when it is pointed to a physical drive name, but not when I use a machine name.
I.e.
This works -
SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name="C:\\temp\\folder1\\folder2\folder3""
This fails -
SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE TargetInstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name=\\\\machineName\\folder1\\folder2\\folder3"
The failing code does not throw any errors (i.e. SSIS thinks the WQL syntax is correct), but it doesn't pick up any dropped files.
Am I doing something incorrect with the syntax, or must I use a physically mapped drive letter?
Thanks

My SSIS control flow includes a standard "textbook" WMI Event Watcher Task that monitors a folder for incoming files. Generally it works fine, but now I regularly see the error message:
"Watching for the Wql Query caused the following system exception: "Quota Violation." Check the query for errors or WMI connection for access rights/permissions"
I do not see any indication of trouble in the event logs. The SSIS log simply states that it failed.
Is there any magic about WMI Event Watcher?
When I restart, it runs fine for hours.
SQL05 is 9.0.3054 on W2003 with all microsoft updates applied. It is basically a bare machine with SQL Server, SSIS running and a service that kicks in occasionally.
Thanks for reading!

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 know a WMI event watcher can be used to watch for a new file being added to a folder. However, I need to check for new folders being added to an existing folder. I haven't been able to find a post on doing this. Is there a way in WQL to check for a new folder being added instead of a new file? I've used SQL for years, but am new to SSIS.

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?

Hi,
I am trying to create a simple BI Application for SSIS. In Visual Studio 2005 I just get a Data Flow Task from the toolbar and add it to the project. When I double click it I get the following error:
The task with the name "Data Flow Task" and the creation name "DTS.Pipeline.1" is not registered for use on this computer.
Then when I try to delete it it gives this other error:
Cannot remove the specified item because it was not found in the specified Collection.
I am creating this application in an administrator account in this computer, so I doubt the problem is related to permissions. I am running SQL Server 2005 and Visual Studio 2005 in WinXP Tablet PC Edition.
Any suggestions why this is happening and how to fix it?

I am using the "Transfer SQL Server Objects Task" to copy some tables from database A to database B including data.
The tables, primary key constraints, Foreign key, data and all transfers nicely except for "DEFAULT CONSTRAINTS" on the tables.
I have failed to find any option in the "Transfer SQL Server Objects Task" task to explicitly say "copy default constraints". So I guess logically it should happen automatically but it doesn't. I hope it is not a bug :-)
Any option anyone knows will help.
Thanks.

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.

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.

In short, does the €œTransfer SQL Server Objects Task€? support distributed transactions?
In trying to use a €œTransfer SQL Server Objects Task€? in a container using a transaction on the container. The task is set to support the transaction. It is setup to copy table data from several tables from a non-domain server (sql server 2000) to a domain-based server (sql server 2005). I get an error stating, €œThis task can not participate in a transaction€?.
I am wondering if it means exactly what it says €“ this task in SSIS can€™t participate at all. Or does it mean that it won€™t in this scenario for some reason. I attempted a simple copy of data from mssql 2005 to mssql 2005 (same server) and the task still failed). MSDTC appears to be running properly on my machine and such (I can do a simple distributed transaction across linked server to the 2000 server in Query Analyzer (QA)). Also, MSDTC appears to be working on both servers with distributed transaction query tests in QA.
Here€™s the error info€¦
SSIS package "Development BusinessContacts and Products Migration.dtsx" starting.
Information: 0x4001100A at Copy BusinessContacts Data: Starting distributed transaction for this container.
Error: 0xC002F319 at Copy BusinessContacts database table data 1, Transfer SQL Server Objects Task: This task can not participate in a transaction.

I have made one package which extracts data from the source does transformation and submits the data to destination. Subsequently it also updates the required control files.
Now I want to add a functionality :
If the package is executed again it should check the status of previous execution in control file if success mark all tasks disable and stop
if failure mark all tasks at enable and start extracting data and continue further with execution.
I was able to attain similar functionality in SQL Server 2000 using activeX script. What code do I need to write as a part of Script Task in order to attain above functionality.
