Deploying Custom Task To Production Server
Apr 12, 2006
This seems like a rather simple questions that I've hesitated posting for a day now, but as of yet I can't really find an answer through my searches online.
My SSIS package is using a couple of the Konesans Transforms, this worked fine on my development box with my dev SQL server. The time has come now to deploy my package to my production SQL server. The instructions on installing the transforms on my dev box all uses Visual Studio to add the components.
Is there a way to deploy 3rd party (own my own) SSIS tasks with the package? Does it require a seperate install? How can I do it without Visual Studio?
Thanks for any help,
-Dan

hello experts,
i need help with deployment of reports (SSRS 2005). we need to deploy many reports (more then 100) on the production everytime we make changes in them.
"the problem is we cannot install visual studio on the server to open the project and use the deploy option from it" i tried using the script - PublishSampleReports.rss
but everytime i run i need to go and manully configure the report to map the shared datasource to it. any way to pass the information in the script itself, or is there any smart way to deploy on production.

Hello All,
I am having an issue deploying reports to my Production server via VS 2003 IDE.
The scenario is that I have a dev box with all 3 components installed on the same server(VS 2003, SQL 2000, sp3 , IIS and Report Server). I have no problem deploying to this Dev server. Now I need to deploy them to a different server(Release) in a different Domain. The Release implementation is, IIS and Report Services installed on one Server and SQL instance on a different server , but both IIS and SQL server are in the same domain. So in my VS 2003 IDE I choose a project/solution and then right click to Deploy I get an error " A connection could not be made to the report server <server URL>". My Solution Property page "Target Server URL " is pointed to this Release server virtual directory(http://Release:81/Reports). This Relase IIS web server has different web site, I installed the RS in the Default website.
I can browse RS server(http://Release:81/Reports) from anywhere via web and get to Site settings and all, But I cannot deploy from VS2003. Am I missing anything? Earlier I used to get at least log-in credentials to enter my UID and PW, as I provide them I never got anything back, it keeps asking me for UID and PW. Now I straight away get "Conection could not be made" error.
Any insights will be very helpfull.
Thank you
Ranjit

Dear fellow developers,
I have successfully developed a Transact-SQL stored procedure which calls a CLR function, which calls a web service. I am using a Visual Studio 2005 SQL Server Project to perform the necessary magic.
Is there a neat way to deploy this stuff to a production server?
It is bad enough deploying the sp and function, but the web server proxy also needs to be changed to refer to the production web service.
This all looks very nasty and complicated.
Am I missing something?

Was wondering, when performance changes have been made to existing code and deployed to a production environment, should anything be done regarding clearing old cache?
Is there a risk of the new code picking up cold or wrong cached query plans etc?
I know you can't clear the cache for the full system as it will affect everything else. But are the ways to target the changes? I.E run the new code with an OPTION (RECOMPILE) few times to build up new clean plans for it to use?
Or will the update stats see it is using bad plans and then start creating new clean ones over time?

Hi
I need to move my packages from development to production.
In the development the database name is dev and in producton it is prod.
The username passwords are also different .
When i deploy my packages in production i dont think so it will work any pointers on how to make these things configurable like when the person deploying this package runs it he is prompted for the connection string and username and password
regards

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.
Thanks!

I have developed a custom report item that works fine in design and preview mode while in Visual Studio. I cannot get it to show up on my deployed reports. Here's what I have done so far:
1. Deployed the report using Visual Studio
2. updated the rsreportserver.config file with the following entry:
<ReportItems>
<ReportItem Name="PedigreeChart" Type="Uabr.Rap.PedigreeChart.PedigreeChartRenderer, Uabr.Rap.PedigreeChart" />
</ReportItems>
3. Updated the rssrvpolicy.config file with the following entry.
<CodeGroup
class="UnionCodeGroup"
version="1"
PermissionSetName="FullTrust"
Description="This code group grants Uabr.Rap.PedigreeChart.dll FUllTrust permission. ">
<IMembershipCondition
class="UrlMembershipCondition"
version="1"
Url="C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting ServicesReportServerinUabr.Rap.PedigreeChart.dll" />
</CodeGroup>
I've also tried using the StrongNameMembershipCondition with no better results.
4. The dll and its dependencies are copied to the bin directory of the report server.
5. When I load a report with this custom report item on it, the report loads fine with no errors or warnings in the log file (even with verbose tracing). The area where the custom item should be is just white. It's almost like Reporting Services isn't registering the item correctly.
This is particularly frustrating because the report works fine in Visual Studio - apparently I configured that correctly. Any suggestions would be greatly appreciated. I'm stumped.

I have recently enabled a custom Forms Security on my Windows 2003 Server w/ SQL Server 2005 Reporting Services. All the functionality I would expect is working properly, except for the ability to deploy to the reports server from inside my Visual Studio 2005 Reports Project.
The 'Reporting Services Login' window opens, prompting me for a username and password. Regardless of what is supplied, the window keeps reappearing, and I am unable to deploy. I am able to upload the files from within the Report Manager, but that is time consuming and inelegant.
Any help would be greatly appreciated!

I'm having a terrible time trying to figure out how to do this, does anyone have experience?
My code works fine in the report viewer, but all I get from the deployment is #Error symbols. I've added my custom dll file to the config file and gave it full trust, as well as the URL of the web service I'm calling. I've even modified the rest of the codegroups within the file to FullTrust just in case.
I've also added the [assembly: AllowPartiallyTrustedCallers] to the AssemblyInfo class, and [WebPermission(SecurityAction.Assert)] to the constructor of my custom assembly no avail.
I'm at a complete loss now as to why my deployment cannot run this code. As far as debugging goes, Visual Studio is not located on the reporting server, nor is it an option to have it put there. I've been able to run the code with the web service lines commented out, but as soon as I put even the webservice.Credentials = CredentialCache.DefaultCredentials in I'm greeted with the nice and calming #Error.
Any suggestions?

Hi,
I have been struggling to deploy a custom rendering extension onto
Reporting services 2005. I have followed all the steps given in the
MSDN article
http://msdn.microsoft.com/msdnmag/issues/05/02/customrenderers/defaul...
Especially -
1. Copied the dll generated to the reporting service bin folder.
2. Made the entry in C:Program FilesMicrosoft SQL ServerMSSQL.
3Reporting ServicesReportServer
sreportserver.config file as
<Extension Name="CUSTOM_RENDERER"
Type="MSDNMagazine.CustomRSRenderer.Renderer,MSDNMagazine.CustomRSRenderer"/
3. Made an entry in C:Program FilesMicrosoft SQL ServerMSSQL.
3Reporting ServicesReportServer
ssrvpolicy.config file as
<CodeGroup class="UnionCodeGroup" version="1"

Description="This code group grants data extensions full trust.">
<IMembershipCondition class="UrlMembershipCondition" version="1"
Url="C:Program FilesMicrosoft SQL ServerMSSQL.3Reporting Services
ReportServerinMSDNMagazine.CustomRSRenderer.dll"/>
</CodeGroup>
I am able to see the extension being listed in the Report manager list
of available rendering options,
But I get the following error from the report server when I try
exporting to the custom rendering extension

I am writing a custom task that has some custom properties. I would like to parameterize these properties i.e. read from a varaible, so I can change these variables from a config file during runtime.
I read the documentation and it says if we set the ExpressionType to CPET_NOTIFY, it should work, but it does not seem to work. Not sure if I am missing anything. Can someone please help me?
This is what I did in the custom task
customProperty.ExpressionType = DTSCustomPropertyExpressionType.CPET_NOTIFY;
In the Editor of my custom task, under custom properties section, I expected a button with 3 dots, to click & pop-up so we can specify the expression or at least so it evaluates the variables if we give @[User::VaraibleName]
Any help on this will be very much appreciated.
Thanks

Hi there,
I'm still pretty new to SSIS, what I am really battling with is getting a custom task to work.
I have developed a custom task, digitally signed it added it to the Global Assembly Cache, written the UI for it - Pretty much as it is done here: http://technet.microsoft.com/en-us/library/ms136080.aspx
but my problem is that when I drag it from the tool box into the control flow pane, I get this message: "The task user interface specified by type name 'XXXXXXXXXXXXXXXXXXX' could not be loaded.
(Microsoft.DatatransformationServices.Design).
Does anybody have an idea of what I am doing wrong here?

Hello All,
We have developed some custom tasks which we currently deploy the standard way. That is, we install the custom task assemblies in the DTSTasks folder and we also install the assemblies in the GAC. Due to some deployment practices we are trying to implement we would like to be able to remove the assemblies from the GAC and install them in some other location. I have tried installing the assemblies in the DTSBinn folder, but this does not appear to be working. When I drop the custom control flow tasks onto the package's control flow tab I get the "Cannot create a task with the name ..." error.
Is it possible to not have the custom task assemblies in the GAC? Are there any tricks to getting it to work?
FYI, our assemblies are signed. I'm not sure if that has anything to do with our troubles.
Thanks,
Rob

Hi,
Had anyone code a custom task UI and used the propertygrid like most of the SSIS components do?
I am having an issue while trying to get the connections from my UI FORM.
They way i did was to get the parent of the form (The package) and then get the connections but that will only work for the FORM if i use the property from the properties panel i throws an error because obviously i dont have the FORM neither the parent...
I now i should use the service provider and get the IDTSconnection... but somehow it always comes = "Nothing"....

Is there a way you can reference a prebuilt CLR function in a custom dataflow task?
The CLR and the custom dataflow task are one in the same. The reason that I'm designing the custom task is that I find that it's time consuming to make a call to the database to retrieve a function to work on something that's already in memory. Also, another reason is that if the code needs to be updated, it doesn't have to be done in 2 places allowing for less confusion.
I tried adding a reference to the CLR function in my SSIS dataflow task, but when I try running it in SSIS, I get the error saying it cannot use a SQL CLR defined task in the package which I believe is due to this reference in the CLR code:
[Microsoft.SqlServer.Server.SqlFunction]
public static string toCase(string text, string caseType)
Is there a way to circumvent the [...SqlFunction] line of code when the DLL is referenced by an SSIS dataflow task, or do I just have to deal with having 2 copies of the same code?
Thanks in advance!

I need to find a better way to handle DTS Job Failure issue. Currently, we have about 50 jobs which executed through DTS packages. Everytime when sources were not there or came in late, the DTS sent out an email to my page which I carried every day. Some those came in during the holidays even though I know the source party won’t generate the source files at that day.
Trying to avoid to get beep everytime when job was failed. Someone suggested that it is possible to add kind of executable file within the Custom task and let it trigger the DTS packages. If, for example, a holiday then don’t run the package so I won’t get the page.
Any hints suggestions would be greatly appreciated

I've created a custom task, and now I want to upgrade it. There's actually no change in the task itself, but I've changed the assembly version number, and now I need to upgrade all the tasks that reference the old version number.
So I rebuilt the task, and I created a policy assembly with a bindingRedirect that forwards to my new assembly. I removed the old version of the assembly from the GAC. All good so far - I've even run the task through the debugger, I open the package as "Reload with Upgrade", and the breakpoints in my CanUpdate, Update and Version overrides are being hit fine. This approach works fine in my custom pipeline components, and the PerformUpgrade override updates the UserComponentTypeName to reflect the new assembly version number (see Milen's post in http://forums.microsoft.com/MSDN/ShowPost.aspx?PostID=893641&SiteID=1).
But the task itself won't upgrade, or at least, it seems to require the old assembly version number. I get an error message:
Code SnippetThe task with the name "My Task" and the creation name "xx.xxx.MyTask, xxx.xxx, Version=0.1.0.0, Culture=neutral, PublicKeyToken=xxxx" is not registered for use on this computer.
Has anyone got any ideas what I'm doing wrong? I've got 40 or so packages with 2 tasks in each, and I don't really want to have to delete and add them to each one ...

Hi there,
I have an issue that feels like it requires an Unpivot task, but I'm struggling to visualise the best way to do it. I'd be grateful for any advice on this.
I have this dataset in my pipeline
moduleid
startdate
modenddate
Revenue
MonthsOnModule
800091
05/09/2007
30/12/2007
150
3
800094
05/09/2007
30/11/2007
148
2
800095
05/09/2007
30/12/2007
300
3
Basically, each module has a start date and an end date. Therefore, with a simple datediff, we can get to MonthsOnModule.
Each module attracts an amount of revenue, which need to be allocated equally to each month over which the module runs.
In the example above, Module 800091 lasts 3 months, generates £150 revenue, so in September 2007, it attracts £50, in October 2007 It attracts £50, In November 2007 it attracts £50.
I'm using this package to populate a fact table in an OLAP Data Warehouse. The destination table needs to hold the data like this:
moduleid
Month
value
800091
200709

Now that looks like a pretty straight unpivot, but in order to unpivot, you have to have columns to unpivot into rows. In this case, I would need one column for each month that the module lasted. Modules can last any number of months. Some last 40 months, and there is no reason why one couldn't last 100 months or more.
I just can't really seem to visualise my approach to this transform. Anyone got any ideas?
Thank you

I've written several custom Control Flow and Data Flow components for SSIS. I'm trying to deploy a new Control Flow Task, however it will not show up in the "Choose Toolbox Items" window.
I have my dll's all in the right place. Because of other painful issues we have not used the GAC, and instead have put our DLL's that are referenced in the following directory: C:program filesMicrosoft SQL Server90DTSBinn. This has worked fine for other custom tasks, but not for this one.
The only things that are different about this transform are the following:
1. Not only does the task inherit from Task, it also implements two interfaces that I wrote.
2. One of the assembly references is actualy an executable instead of a dll. This is unusual, but I've done it with other .NET projects and not had any trouble.
I could move the code I need from the EXE out to a DLL. If somebody knows what could be causing this please respond?

I wrote a custom task following the outline on MSDN. I signed it and installed it into the Tasks folder and in the GAC.
When I go to an SSIS project and add my task, the properties window shows "Could not get value for property 'd61935d9-430b-4c93-9f3e-a29f720d8659'. Specified cast is not valid." (where the guid is different obviously) for many of the properties.
What have I done wrong?
Update: I know this isn't my code because I tried a simple task that just returns success and doesn't do anything. I get the exact same errors, so I must be installing it incorrectly.

I've been playing around with building custom components for SSIS. I've been doing workflow for years (using Java and Oracle). The company I worked for had a framework for publishing data that allowed for user interaction. That's something I'd love to be able to do in SSIS.
Is it possible to create a custom task that interacts with the user at runtime? So, the user starts the SSIS package. At some point, the process pops up a dialog (Windows Form) that asks the user to set a date using a calendar control.
Any thoughts?

I'm trying to create a custom data flow destination, and it has a custom property that needs to get value from variable(similar to the FileNameVariable property of Raw File Destination), how can I do that?

Hi Everyone,
I created a script task that uploads a file to a HTTPs site. The script task works well and now I want to turn this script task into a custom component...
I'm having problems on how to call the variables I have in the package, I already locked them for reading, but how am I suppose to access them and how can I put their values into strings so I can easily call them in the WebClient.UploadFile method?
Also, I am very new to custom tasks in SSIS.. and would appreciate if anyone of you can send me something (code, link, etc.) of a very simple custom task without any form or properties, that I can try to study.
Basically, what I want my custom task to do is,
1. Read the varialbes in the package.
2. use the variables values as input in my WebClient.UploadFile("varURLstring", "PUT", "varFilePath")
as you can see, my custom task is really simple... but I'm a noob here and I don't know where to go.
Thanks in advance,
Kervy
