I have seen a number of posts regarding parallel development of SSIS packages and need some further information.
So far we have been developing SSIS packages along a single development stream and therefore have managed to avoid parallel development of our packages.
However, due to business pressures we will soon have multiple project streams running in parallel, and therefore multiple code branches, as part of that we will definitely need to redevelop the same SSIS packages in parallel. Judging from your post above and some testing we have done this is going to be a nightmare as we cannot merge the code. We can put in place processes to try and mitigate this but there are bound to be issues along the way.
Do you know whether this problem is going to be fixed? We are now using Team Foundation Server but presumably the merge algorythm used is same/similar to that of VSS and therefore very flaky?
However, not only are we having problems with the merging of the XML files, but we also use script tasks within the packages which are precompiled, as the DTSX files contain the binary objects associated with the script source code, if two developers change the same script task in isolated branches the binary is not recompiled as the merge software does not recognise this object.
Do you know whether these issues have been identified and are going to be fixed to be in line with the rest of Microsoft Configuration Managment principles of parallel development?
I am facing some problem's while using the FOR loop container to execute 7-10 packages in parallel.
The main package has 7 FOR loop containers say F1-F7.
Each FOR loop container has 2 task's
T1==> exec child package C1
T2==> exec delay task Delay1.
The idea is to run child packages c1-c7 in parallel ...delay for some time and then run again since there are in the FOR loop container.
I am facing someproblems.
1. The execution of tasks T1-T7 is not guranteed. This means SSIS picks up any 6 tasks of T1-T7 randomly to start with. 6 is the max it processes whereas i have more than that. Can i change this setting???
2. Its not guranteed that if say Task t1 of FOR loop F1 is executed the subsequent task for Delay within tat For loop would be executed next. Typically wat happens is it starts with T1-T6 (T7 onhold) and then exec the delay for T1-T5 and passes control to T7 without going into the delay for T6.This is not the intended execution.
What i want is exec T1-t7 ..delay for the next exec and start again.
Dear all I have developed some packages (around 40) on my local system. now i m trying to move the integration services project on the production server. when i double click on the intergration services from the local drive of the server all the packages are up(works fine till here) now i open any of the package-->this is what happens Prompt1)-->TITLE: Microsoft Visual Studio ------------------------------ There were errors while the package was being loaded. The package might be corrupted. See the Error List for details. ------------------------------ BUTTONS: OK ------------------------------
i press ok and then the prompt comes Prompt2-->There were build errors.Do you want to continue with the last build and continue..yes..no.. i click yes ..and then error comes
prompt3--> Error loading RTS-IMRB-DISTRIBUTION.dtsx: The connection "Excel Connection Manager" is not found. This error is thrown by Connections collection when the specific connection element is not found.
and finally the prompt for the OLE DB error prompt 4-->[OLE DB Destination [14]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "NDELNTX46.IMRB RTS.siddharth" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
Possible work around suggested to me was that in the base system(read local) before exporting go to package properties and the security and set the security as "Encrypt all with password" and also put some Password which i did and it worked for one. other thing i thought off was creating the configuration file but first i thought of fully running one complete package on the production and then think of the configuration file. so i went inside the invidual excel connection and pointed it to the correct new file location and also edited the OLE DB database connection and put my user name and password and checked save password and trying to run the entire thing. but still the same problem.. one more thing i observed was that my OLE DB was going off everytime i am running the package.and i have to enter my password again...so othe save password i guess is not working
I know its a little long post..but i wanted to explain the entire process and problem to all with description. all suggestions are welcome
I have stumbled on a problem with running a large number of SSIS packages in parallel, using the €œdtexec€? command from inside an SQL Server job.
I€™ve described the environment, the goal and the problem below. Sorry if it€™s a bit too long, but I tried to be as clear as possible.
The environment: Windows Server 2003 Enterprise x64 Edition, SQL Server 2005 32bit Enterprise Edition SP2.
The goal: We have a large number of text files that we€™re loading into a staging area of a data warehouse (based on SQL Server 2k5, as said above).
We have one €œmain€? SSIS package that takes a list of files to load from an XML file, loops through that list and for each file in the list starts an SSIS package by using €œdtexec€? command. The command is started asynchronously by using system.diagnostics.process.start() method. This means that a large number of SSIS packages are started in parallel. These packages perform the actual loading (with BULK insert).
I have successfully run the loading process from the command prompt (using the dtexec command to start the main package) a number of times.
In order to move the loading to a production environment and schedule it, we have set up an SQL Server Agent job. We€™ve created a proxy user with the necessary rights (the same user that runs the job from command prompt), created an the SQL Agent job (there is one step of type €œcmdexec€? that runs the €œmain€? SSIS package with the €œdtexec€? command).
If the input XML file for the main package contains a small number of files (for example 10), the SQL Server Agent job works fine €“ the SSIS packages are started in parallel and they finish work successfully.
The problem: When the number of the concurrently started SSIS packages gets too big, the packages start to fail. When a large number of SSIS package executions are already taking place, the new dtexec commands fail after 0 seconds of work with an empty error message.
Please bear in mind that the same loading still works perfectly from command prompt on the same server with the same user. It only fails when run from the SQL Agent Job.
I€™ve tried to understand the limit, when do the packages start to fail, and I believe that the threshold is 80 parallel executions (I understand that it might not be desirable to start so many SSIS packages at once, but I€™d like to do it despite this).
Additional information:
The dtexec utility provides an error message where the package variables are shown and the fact that the package ran 0 seconds, but the €œMessage€? is empty (€œMessage: €œ). Turning the logging on in all the packages does not provide an error message either, just a lot of run-time information. The try-catch block around the process.start() script in the main package€™s script task also does not reveal any errors. I€™ve increased the €œmax worker threads€? number for the cmdexec subsystem in the msdb.dbo.syssubsystems table to a safely high number and restarted the SQL Server, but this had no effect either.
The request:
Can anyone give ideas what could be the cause of the problem? If you have any ideas about how to further debug the problem, they are also very welcome. Thanks in advance!
Please can anybody help me in transferring existing SSIS Packages saved in a shared folder location from development server 2ED to Live server TWD1. Both has SQL server 2005 running and has visual studio 2005 Currently about 25 SSIS packages are executed from the development server transferring data on Live server TWD1...these ETL process is called from development server but executed on live server. Now the problem is when i call these packages from the shared folder from live server it crashes.....i need to changes something to shift the whole package to the live server..and execute on live server itself instead of recreating the whole 25 process from scratch.....also i use optimize for many tables ..and run in a single trancastion....so how can i see the mappings of source and destination tables.
Please let me know the process how i can achieve this. Thanks George
I have several packages within secuence containers and into one main dtsx package with a checkpoint configuration and when I run it some succeed and some don´t. The problem is that when I rerun it checkpoint doesn´t seem to work ´cause some of the successful packages are rerun as well (and not skipped as it should be...) In other words, the process does not begin on the point of failure..
Seems to be that packages that finish after the failure point (and succeed) are not registered in the checkpoint file, then when I rerun the main package these succeeded packages are rerun too....
I come from other ETL tools (Oracle Warehouse Builder, BODI, BODS & DataStage) and i'm having trouble finding the best practice for scheduling a collection of packages to be processed parallel en retry those that fail. I created a staging project which contains all the packages (50) that extract data from 1 source system and grouped the packages into 2 sequence containers to make sure that the 'heavy' packages are started first and together in parallel.
I soon discovered that there is no standard option to have one child package retry on failure. Currently if 1 package fails the whole project is retried. I explored checkpoints as a solution but that seems a dead end when running packages in parallel.
There seem to be 2 solutions for my issue:
(1) create a loop around every EPT with 3 variables (waittime, retry_counter & succes_flag) (2) create an event handler to keep a list of ID's that failed and enable/disable EPT's based on that list (there's a lot more to it).
Option 1 seems like a lot of bloatware in what i expected to be standard functionality. I'm still investigating option 2.
How do others handle this kind of scheduling? Is it so different with SSIS that i'm approaching this incorrectly ?
I'm pretty new to SSIS but I've managed to cobble together a number of individual packages to refresh SQL tables from a 3rd-party database. Â Now, what I'd like to do is have a single package that I can use to invoke each of the individual ones. Since it will run on a quad, I'd like to invoke them such they'll run in parallel.
I'm expecting to run 3 isloated version of the package with in first version VARA=1 VARB=0 VARC=0 second version VARA=0 VARB=1 VARC=0 third version VARA=0 VARB=0 VARC=1 but it doesn't seem like doing that the maxconcurrent variable is set to 40 to be on the safe side.
when I run I get
first version VARA=1 VARB=0 VARC=0 second version VARA=1 VARB=1 VARC=0 third version VARA=0 VARB=1 VARC=1
I have a system of SSIS packages in which several packages perform the same lookup on the same table. E.g., i have PackageA, PackageB and PackageC all doing a lookup on TableA. All of these packages are spawned by the same PackageD and run frequently. In some cases, there is an issue with concurrency on these lookups. I get the following exception :
" The ProcessInput method on component "LKP Lookup SecurityID" (6658) failed with error code 0xC004702C. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
"
The hex code of this exception corresponds to the following description : "DTS_E_BUFFERNOTLOCKED. This buffer is not locked and cannot be manipulated." That's as much as i could find on this.
My suspision is that the SSIS engine somehow figures that the lookup in these distinct packages is the same one and builds a shared version of the lookup table in memory. Then there is some sort of a multi-threading issue in accessing this shared memory which leads to the exception above.
Has anyone experienced this? Can someone shed some light on this?
We have a system here where we develop SSIS packages on a development server. I am trying to figure out the cleanest way to promote these changes to a production server where stored procedures/tables that are used in the package are not deployed yet.
When I switch the connection in the package to the production server there are alot of objects in the package that are "invalidated" because they are trying to verify existence of tables/columns. One example is outputing the results of a query to a text file. The text file destination gets a red X on it because it cant grab the columns from the source query (because that stored procedure doesnt exist yet)
Is there a best practices or something on how to deploy packages to a production system? I have tried turning off "ValidateExternalMetaData" with no success.
While developing the packages in our developers environment the packages should be stored in file system. Once after the completion of the development, while moving these packages to upstream environments the packages should be deployed to sql server. Is this scenario possible? If possible, can anybody give me some tips for how to do that.
Basically It is like the developers make their changes in the file system packages (internally versions are mainintained by source control). After the completion of the development whenever we do a build and deploy to the upstream systems we should move the packages from file system to sql server database. There is a scheduler in sql server which is responsible for executing these packages.
Can anybody give me some examples?
Another question.
Assume that in the developers environment there is a central sql server database which is storing all the packages in MSDB database. Suppose at a time 2 developers are making modification to a single package. How it behaves? Is parallel developemnt supported in SSIS?
I would like to install the components I need to develop a SSIS custom component. Is there an SDK or install option for just the visual studio components?
I've run into a problem with SSIS packages wherein tasks that write or copy files, or create or delete directories, quit execution without any hint of an error nor a failure message, when called from an ASP.NET 2.0 application running on any other machine than the one where the package was created from. By all indications it appeared to be an identity/permissions problem.
Our application involves a separate web server and database server. Both have SQL Server 2005 installed, but the application server originally only had Integration services. The packages are file system-deployed on the application server, and are called using Microsoft.SqlServer.Dts.Runtime methods. For all packages that involve file system tasks, the above problem occurs.
When the above packages are run using the command prompt (either DTEXEC or DTEXECUI) the packages execute just fine. This is expected since we are using an administrative account. However when a ShellExecute of the same command is called from ASP.NET, the same problem occurs.
I've tried giving administrative permissions to the ASPNET worker process user to no avail.
I have likewise attempted to use the SQL Server Agent job approach but that approach might not be acceptable for our clients since it means installing SQL Server 2005 Database services on the application server.
I have read the relevant threads in this forum, namely http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=1044739&SiteID=1 and http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=927084&SiteID=1 but failed to find any solution appropriate for our set up.
We manage some SSIS servers, which has only SSIS and SSIS tools installed on them and not the sql server DB.
SSIS packages and configuration files are deployed on a NAS. We run the SSIS packages through DTEXEC by logging in to the server.
We want to allow developers to run their packages on their own on the server, but at the same time we dont want to give them physical access on the server i.e we do not want to add them into RDP users list on server properties. We want them to allow running their packages remotely on the server.
One way We could think of is by using powershell remoting and we are working on that. But is there any other way or any tool already present for the same.
Can we execute multiple instances of the same SSIS package simultaneously?? If yes, how? If no, what is the work-around to simulate such a functionality?
I've made a query like the one in msdn (SELECT * FROM __InstanceCreationEvent WITHIN 10 WHERE Targetinstance ISA "CIM_DirectoryContainsFile" and TargetInstance.GroupComponent= "Win32_Directory.Name="e:\\temp""). I have 20 similar tasks for watching in different folders, but when there are too much tasks in parallel, it doesn't work anymore. I change the numbers of executables to 128 (in the general properties of the package (to test)) but it doesn't seems to work.
I don't understand why it works when there are only 1 or 2 (6 seems to be the maximum) tasks and not if there are more than 6.
Could you help me with this issue?
Configuration : Windows Server 2003, SQL Server 2005, SSIS, Sql Server Agent
We have been facing some delevelopment issues with SSIS. These are as follows:
We want to execute some tasks in a particular package depending on a condition. Example: If record count is more than 0 then go to next task else stop the package. We tried to write a script, in which we evaluate the value of the variable. This variable is populated with the record count value. We cannot find any particular function which can exit the package successfully. We can fail the Task, but that means the package is failed. wo dont want to fail the package. In short we want to conditionally execute some tasks in a package. Something like an "If container" similar to "For container".
We have one main package from which we execute 5 other packages. We want to assign values for connection information and variables in this main package only. The other 5 packages should pick values from this main package.
We are scheduling our package from Windows Scheduled Tasks. When the package is run in this manner, it doesnt read values of variables and connections from configuration file. It uses the values that were provided during development which are embedded in the code.
I could use some help from those of you who have SSIS deployed in a production environment. The developer creates a SSIS package on a workstation with BIDS. Package accesses a network drive and a SQL database on a development server. The developer can test the SSIS package successfully in BIDS.
The only way to use the ServerStorage protect level is that the developer needs to save the SSIS package directly to the development server (we are storing the package in SQL Server). This is not a problem, but it possesses a problem when we need to migrate the SSIS package to the production server. This is because in development our databases are suffixed with the word test. Also, the SQL Server user id that has access to the tables has a different password in production. We run our SSIS packages with the SQL agent. The SQL agent id has permissions to the network drives; the connection information within the package has permissions to the SQL tables.
How can the DBA, who would ideally does not want to and may not be able to due to audit restrictions, update the server name, user password, and database name without using BIDS? I tried using the configuration file option, but that does not seem to work. It keeps deploying the XML configuration file to my local machine even after successfully migrating the package to SQL Server.
To me, the DBA should simply need to run the deployment wizard and target the production server. At the time of the deployment, the wizard should prompt for items that need to be updated, and the settings should be stored in SQL Server. I know this scenario sounds exactly like those presented in the docs, but I must be doing something wrong.
In the past I wrote DTS transforms entirely by myself. With SSIS, our team of several developers now wants each member to develop a piece of the same package.
Do SSIS packages support this type of simultaneous multi-developer creation or is it a "one developer at a time" type product?
I have a SSIS package that runs fine when I execute it in visual studio but when I run it on the server as a job it fails. This is nothing to do with protection levels etc as the job is running. It fails part way through with this as the error log

It is failing on the last file it is trying to import but it works OK on my PC.
Can anyone give me any pointers on what might be causing this.
Having a difficult time setting up a development environment and a set of standards for SSIS package development.
First of all, you can't run the dataflow object "SQL Server Destination" in BIDS because BULKCOPY can only be run from the actual server. So how do you test/debug a package with this object in it?
Second of all, if you create an SSIS package on a developer computer in BIDS, and then import it into the SSIS package store on your development SQL server, you can't run the package from Management Studio on the developer PC. You get the error "DTS_E_PRODUCTLEVELTOLOW" when it tries to run any of the SSIS. Do I have to have SSIS installed on the developer client machine? How do I do that without installing a full server instance on each client machine (not to mention the licsense issues)?
Lastly, what protection level would you suggest using for production? We are having issues with ODBC connection passwords being decrypted and thus package steps failing in using "EncryptSensitiveWithUserKey". What exactly does this protection level do? Our network is physically very locked down, so we arent worried about SSIS package security too much, just looking for a way for them to work reliably without having to setup complicated security scenarios.
Does anyone here have a favorite site or set of sites with resources on SSIS custom component (tasks, transforms, log providers, etc.) development? I've been searching around to try to find this on my own, but so far I've had little luck.
Darren - I've noticed that you always seem to have the most insightful responses to questions related to SSIS .NET development (such as your recent response to evaluating expressions in a custom component) so I am particularly interested in anything that you have to share.
When I run a package I created in the development Studio it runs fine but if I create a job and run it I get an error "The AcquireConnection method call to the connection manager "ODS" failed with error code 0xC0202009"
I have the package setup to use a XML config file and it works fine on all the other packages but this one will not work.
When deploying a project from within a SSIS project in Visual Studio 2012 to SQL Server 2012 Integration services server I get the follwoing error message:

I have created SSIS (.dtsx) files and have stored in different servers. Now my query is I want to move all dtsx files from filesystem to Sqlserver2005 database how should i do it.
I need to create the ssis package in business intelligence developement studio i am need to sqlserver 2005.When i opened the BID studio i am not able to see the integration services packages type.. Please help the steps to design the package.
I have experience of using the 2000 in dts designer mode.
I upgraded to Microsoft SQL Server 2005 Service Pack 2 and now when I run the master SSIS package( that has several packages in it), all the packages run twice.
After removing SP2, they work fine. Any ideas how to make this work with SP2?
I am writing a vb application that is supposed to let the users set the connection string for the datasources in the package. After new connection strings are entered the application is supposed to run 8 packages in a certain order, but I haven't been able to set a new connection string successfully. Is there a way to programmatically modify the connection string of a package's datasource? (the packages are moving data from a D3 database to sql server 2005)
Here is what I have tried so far:
A. Dim pkgLocation As String Dim app As Application = New Application() pkgLocation = "c:Package1.dtsx" Dim pkg As Package = app.LoadPackage(pkgLocation, Nothing) Dim myConns As Connections = pkg.Connections
MessageBox.Show(myConns(0).ID.ToString) Dim myConnMgr As ConnectionManager = myConns(0) Dim connProperties As DtsProperties = myConnMgr.Properties
I am connecting to a DB2 mainframe to pull data into SQL 2005. Very simple import. SSIS package works fine on 32 bit. However, once deployed to the 64 bit machine, I get "invalid product license" on the Acquire Connection method.
I've worked with IBM support. I have the correct version of the DB2 Connect client installed. The license is there and in the right place. I can connect to the mainframe from the 64 bit server using the DB2 client tools. I just can't seem to execute the package from Integration Services or run a job in SQL Server that executes the package.
According to BOL, the package should automatically detect the 64 client I installed. It and the 32 bit client I developed with share the same name/id.
