Package Configuration, Parent-child Packages And Job Scheduling
May 3, 2007
Hi,
I've found this problem that when I change settings in my configuration file it does not automatically apply to all child packages which uses the same configuration file if run from a job in SQL Server Agent. I need to open the package and save it again from BIDS. I use one "load group" package to execute all other packages.
Is there a way from the job configuration to set a setting so the package allways will have the newest configuration?
Regards
Simon

Hi guys,
Here's the deal. I have a child package, (say, pack01.dtsx), which uses a dtsconfig file for its connection string, which can be called from other packages, but which also can be called by itself.
However I also have another package (say, pack02.dtsx) which uses the same dtsconfig file for its connection string. It calls on pack01.dtsx.
When I use DTEXECUI and run pack01.dtsx, specifying the proper .dtsconfig file, it goes well. But when I try and run pack02.dtsx, an error occurs saying pack01.dtsx connection cannot be established.
How do I pass the connectionstring being used by pack02 to pack01, without having to remove the configuration file setting of pack01? Can a Parent Package configuration and a configuration file try and map to the same property?
Hope someone could help. Thanks.

I currently have multiple (parent and child) packages using the same config file. The config file has entries for connections to a number of systems. All of them are not used from the child packages. Hence, my child package throws an error when it tries to configure using the same config file because it can't find the extra connections in my connection collection.
Does anyone have any ideas on the best way to go about resolving this? Is multiple config files (one for each connection) the only way?

Hey...
I am running a parent SSIS package (running sp2, 9.0.3042) that calls several child packages.
On our development server, we now cannot run this because we get 1 or more of these errors:
"Error 0x80004003 while preparing to load the package. Invalid pointer . "
"Error 0xC0011008 while preparing to load the package. Error loading from XML. No further detailed error information can be specified for this problem because no Events object was passed where detailed error information can be stored. . "
It is not occuring on the same packages. It varies every time it is run.
I can run every one of the child packages individually, using the same login ID that the parent is executed under.
The parent package works fine on my local machine and other servers running the same version of SSIS. Just not on this server.
Does anyone have any ideas???
Thanks

I have a fairly simple SSIS project that has nested parent-child packages.
I am trying to find the best way to manage the connections strings so as to make the package portable across machines and environments. Currently there is one "master" package which calls 6 child packages. 1 of these child package calls 3 child packages of its own.
For the database connections, I've settled on creating a standardized .dtsConfig file for each server/login. This is a relatively small number (intially 8) that I don't expect to grow much.
I've taken a different approach for the file-system connections used by Execute Package components that call the child packages. For each package that has child packages, I store all the connection strings (paths) to the child packages in a single .dtsConfig file. This works well for the top-level "master" package where I can pass in the .dtsConfig file (that has the paths to the child packages) as a run-time option in the Execute Package Utility.
However, this approach seems to fall apart for the 2nd generation package that in turn call 3rd generation packages because I don't know how to get the .dtsConfig file (with the 3rd generation .dtsx package paths) path to this downstream dtsx package.
Though I'm sure there are others, the only two solutionsI can think of now are
(a)don't nest packages beyond 1 parent/child relationship -- not really an option or
(b)Store the path of .dtsConfig files for each .dtsx package as an environment variable on each machine. This option is unappealing because it would require adding an environment variable for every .dtsx package that has child packages. I don't think it would take long for this to grow into a large number, that would make managing environment variables cumbersome.
So far my experience with SSIS has been that there was a simple solution for each scenario I had. So this hoop jumping I'm going through seems to indicate I am just missing something.
Is there a better way I am just not getting?

Hi there,
I have a Business Intelligence project containing 4 packages. One of the packages is a parent package that just runs the other 3 packages sequentially (passing in variables via Package Configurations).
When I set the properties of the Execute Package tasks in the parent package, it seems that I can only select SQL Server or File System locations for the child packages.
What I want to do is for the parent to run the packages in the Visual Studio Project so that I can debug the whole process. I don't want to be bothered deploying the child packages so that I can run them from the parent, at least not while I am debugging the whole process.
How do I get the children to run within Visual Studio as well as the parent? I can't for the life of me find anything on the MSDN about this.
Many thanks in advance.

Hi All,
I though i'd been going about setting up my SSIS package to run via a SQL job in the correct way. It would appear however that is not the case.
I have 4 SSIS packages, one of which is the parent package which calls the other three in sequence. I want to run this from a SQL job so that it calls the parent package and it deals with the others. There are connection managers in the package which use a SQL account to access the relevant databases. In addition i have encrypted the package.
I have set up a configuration file which holds the password package and the BillingSystem connection manager password. This file is re used by each package.
After deployment i have set up the SQL agent job to run the parent package. The job returns an error. Looking at the SSIS logging it appears that it completes the SQL task in the parent package and then fails when trying to launch each of the sub packages with an error stating that the SQL account used in the connection manager login failed. It looks as though the sub packages are not getting the password value from the configuration file and this is causing the failure. I though that each package would automatically pick up the config file as it has been setup to do. I have specified the configuration file in the SQL job but this appears to make no difference. Running the integrations seperately i have to add the configuration file in manually to the Run Package dialog box before they will work. This is not saved for the next run.
Can anyone help me get around this problem as i think i have the wrong idea as to how it is supposed to work.
Cheers,
Grant

I have one package that executes 4 child packages (5 total). All 5 packages are set to log information using a connection string with a variable set at runtime for the location. The child packages use a parent variable to get the log connection string from the parent package.
The parent package logs fine, but a strange behavior occurs with the child packages.
The child packages all log data to the location used in the configuration file variable during runtime (like it's supposed to). However, I would get an error right before the first child package finishes execution saying path not found. Just for giggles, I created the folder I use in my development environment on the production environment. The error goes away, but the log file is created in that folder with no data in it. Subsequently, the log file with the data is created in the location set in the configuration file. Now I have two log files!!!!
Anybody know how to fix this?!

Has anyone had experience of using Parent/Child packages while enlisting them in Transactions.
I tested this on a small sample and thought that I had got it to work, but in my real-world package it does not.
The parent package essentially calls three child packages.
In each child package there are multiple DFT's that import and transform data into SQL Server.
All data must be imported or not at all.
Therefore I created a FELC container into which three Exec child package tasks were placed.
The FELC is set to Trans Option 'Required' and the Exec child package tasks to supported.
Unfortunately upon failure of one of the DFT's in the child the data was not rolled back.
So initially we had in terms of container hierarchy for the Trans Option property:
Parent package Supported
FELC for calling child packages Required
Task execute child package Supported
Child package Suppored
Tasks Suppored
Looking at this more closely we thought that we would need
Parent package Supported
FELC for calling child packages Required
Task execute child package Required
Child package Required
Tasks Suppored
for it to work.
However, the latter now gives us failures with error messages on the tasks on the child packages.
[Execute SQL Task] Error: Failed to acquire connection "Conn ECARS1CEDImport". Connection may not be configured correctly or you may not have the right permissions on this connection.
Even more strange the first couple of tasks in the child pkg complete successfully even though they use the same connection listed in the error.
These tasks also have Event handlers.

Hi,
I created a package which passes some infornmations( through parameters) to its child package.
I need to do some processing in parent package based on execution status of child package.i.e.
if child fails then some operation and if child succeeds then other operation.
To determine the status of execution of child package I am using two differnt constraint ..one constraint is having value "Success" and other having value "Failure".
My problem is that when child packge is executed successfully the constraint with value = "Success" works properly but when child fails the constraint with value "Failure" does not work.

We
have one main package from which 7 other child packages are called. We are using
ParentPackage variables to assign values for variables and database connections.
While the values from ParentPackage variable get assigned to some of the
packages properly, to others it doesn€™t assign the value.
For example:
Except for one of the packages the database connection string gets assigned
properly to all other packages.
Similarly, in another package one of the
variables doesn€™t get assigned. In other packages it is assigned properly.
We
have checked all the other property values and they are exactly the same.
We cannot make any head or tail of this erratic behavior.
Please Help.

hi,
I am interested in Passing value from a child Package variable to the Parent package that calls it in ssis.
I am able to call the Child package using the execute package task and use Configurations to pass values from the parent variable to the child, but I am not able to pass the value from the child to the parent.
I have a variable called datasetId in both the parent and child. it gets computed in the child and needs to be passed to the parent...
Any suggestions?
Thanks for any help in advance..

Given the sample data and query below, I would like to know if it is possible to have the outcome be a single row, with the ChildTypeId, c.StartDate, c.EndDate being contained in the parent row. Â So, the outcome I'm hoping for based on the data below for ParentId = 1 would be:
1 2015-01-01Â 2015-12-31 AAÂ 2015-01-01Â 2015-03-31Â BBÂ 2016-01-01Â 2016-03-31Â CCÂ 2017-01-01Â 2017-03-31Â DDÂ 2017-01-01Â 2017-03-31
declare @parent table (Id int not null primary key, StartDate date, EndDate date)
declare @child table (Id int not null primary key, ParentId int not null, ChildTypeId char(2) not null, StartDate date, EndDate date)
insert @parent select 1, '1/1/2015', '12/31/2015'
insert @child select 1, 1, 'AA', '1/1/2015', '3/31/2015'

Hello All,
I have a SSIS Package with a "Execute Package Task" to call a child package. I am trying to have the master/parent package complete its execution regardless the outcome (failure or success) of the child package. The overall structure of the master package is:
1. Perform Pre-load tasks (stored procedure).
2. Execute Package Task (call child package)
3. Perform Post-load Tasks (stored procedure)
I have try everything and cannot get the results that I want... I have tried the combination of "failparentonfailure", "forceexecutionvalue", etc. The master package stops at childs failure. I would like to resume to completion
Any ideas out there?

I have two SSIS packages in a project, one calling the other. The parent package works fine in my local mechine. After they are deployed to the production, I schedeul jobs to run the packages in the SqlServer. The child package works fine if I run it alone, but the parent package could not find its child package if I run the parent package . As I checked, all xml config files and the connection string pointing to the child package were set correctly. It seems the parent package did not use the xml config file. Can someone help me? Thanks in advance.

Hi everybody,
I moved my packages to the new machine, and have problem with parent variables.
When child package tries to get parent variable value I get an error:
Information: 0x40016042 at LoopPackage: The package is attempting to configure from the parent variable "MAIN_SesId".
Warning: 0x80012028 at LoopPackage: Process configuration failed to set the destination at the package path of "Package.Variables[User::MAIN_SesId].Properties[Value]". This occurs when attempting to set the destination property or variable fails. Check the destination property or variable.
Thanks, for any information.

Hi there,
sorry if the message seems a bit garbled i cannot see the textbox properly with ie7/ff
anyways. the situation.
childpackage contains a loop-container. in there i use an ole-db-source with a variable
based on an expression. ie. "select * from foo where bar=" + len(@[bar]) == 0 ? "initial" : @[bar] + " and etc=1"
where bar is the variable that is set by the loop.
this works great.
however i need to call this package several times, only the expression is a tad different.
so i need a scripttask that sets the expression correctly, then i call the childpackage
and map the current-expression to the expression in childpackage.
how do i do that? or am i doing it wrong?
my script-task looks something like:
dts.Variable("theVar").Expression = " ""select * from foo where bar="" + len(@[bar]) == 0 ? ""initial"" : @[bar] + "" and etc=1"" "
in the childpackage i have a package-conf that maps thevar to thequery with target-object expression.

I have an ASP.NET application that calls a SSIS package. The SSIS package internally calls some other child packages. I observed that sometimes some child pacakges are not even called by the parent. and the behaviour is very indeterminate. sometimes they work fine. sometimes they don't. There is no clue available for this behaviour when the pacakges are not executed. (One general observation is that the memory consumption is very high. but that is the case always.)
I have enabled logging on all child packages. The log is not updated at all when the child packages failed to execute. i.e. the package execution does not start.
Could somebody explain why this is happening? any suggestions/ similar experiences?
Regards

I am trying to figure out how to run an SSIS package that is encrypted but also has a child package which is encrypted. I am trying to run from the cmd line using dtexec and specifying DECRYPT <pwd> for the parent package but how do you specify for the child package.
Please help if you have seen such an issue before or you have a work around.

I have a parent package which calls a number of child packages. Occasionally, I have one child package which starts up and appears to finish but the parent package never gets notification that the child has finished. If I view this in Management Studio's in Integration Services, I can view the packages that are running and only the parent package is running. Because it never gets control back, the next child package will never get started and the parent package will continue to run and never finish.
Any idea what could be happening??

I run into some issues and really need some expert help here.
Here is the problem. I have two packages (parent.dtsx and child.dtsx). Both package have its own configuration file (parent.dtsConfig and child.dtsConfig). The file Child.dtsConfig contains a variable (i.e. "X") that is to be used by Child.dtsx.
Inside parent.dtsx. there is a package-task that calls into Child.dtsx. It worked perfectly well if I run parent.dtsx using Dtexec or from inside SSIS's IDE.
Now I want to programmably call "parent.dtsx" from my C# code. I loaded package using "app.LoadPackage"... Inside C# code, I want to reconfigure Child-package's variable ("X"). I then loaded in "Child.dtsx". However when I run "parent.dtsx" and child.dtsx still loads the original value for "X". The reconfigured value for "X" is not updated.
Please help on how to get around this issue.
Thanks.

In respect to Parent / Child packages, can some one correct me if I'm wrong.
Even if connection managers are created in Parent package, the same needs to be created in child packages if they need to connect to database. On the other hand I can just create connection strings in variable in parent package(instead of connection managers itself) and use parent package variable configuration to configure the connection string of child package with the variable value.
Sorry If I'm confusing
The same with variables, the parent variable needs to be mapped to a child variable(using parent package variable config) to be used in child package, it cannot be used as it is.
Thanks

I have a parent package "A", I also have 4 child packages "B","B1","B2",B3"
In BIDS, I created a file connection in the package "A" to connect to the child packages. So whenever I want to run B1 or B2, I change the path in the file connection to point to B1 or B2 and so on. Since the developement environment is File system this works perfectly fine.
But in the Test / Production environment all packages are stored in the Sql server. How can I paramaterize the child package connection so that I can use configuration / variables to select which child package to execute.
Thanks

Starting with "How to: Use Values of Parent Variables in Child Packages" in the SQL Server 2005 Books Online (http://msdn2.microsoft.com/en-us/library/ms345179.aspx), it seems I need to create a separate package configuration in the child package (of type parent package variable) for each variable I want to pass from the parent to the child. Is that really so? The XML configuration file type allows me to specify any number of variables; how do I do that with the parent package variable?
For that matther, why doesn't the Execute Package Task simply allow me to specify the values of child variables (or other properties) directly? It seems SSIS has made something as trivial as a series of function calls completely opaque:
MyChildPackage(var1=1, var2="foo");
MyChildPackage(var1=2, var2="bar");
MyChildPackage(var1=3, var2="baz");

I have a parent package that calls a child package, when I run the parent package the child package picks up a variable value from the parent in a script task and runs fine, the problem I'm facing is when I run just the child package, the script task fails because it doesn't know about the parent variable. The dilemma I'm facing is in my child script task, if I add the parent variable to the ReadOnlyVariables list then the task fails because the parent variable doesn't exist when I just run the child. If I don't add the parent variable to the ReadOnlyVariabls list then if I try to use it then the task fails saying that the variable doesn't exist in the variables collection.
Is there a way to check for the existence of the parent variable, so when I just run the child package I don't get an error and I don't have to change my task every time I choose to run the child package only vs running the parent/child?
Thanks.

Hi
I have having trouble getting my hands around how to retrieve variables from a parent package. I read about the Environment variables and Configuration File at the parent package level and the Parent Package variable at the child level.
Here are my questions:
1. Can you only store/retrieve 1 variable in a config file at a time?
2. Does the child package have to define the variables and if so, do they have to be the same names as the parent package?
This seems so more more complex then the DTS2000 way of passing variables to and from packages.
Any help would be appreciated.
Thanks in advance,
Gordon Radley

I have two issues:
I have a simple parent that uses an Execute Package Task to call a simple child package. The child package has a Data Flow that I disabled. When running the child package by itself, the data flow task is bypassed. When running the package via the parent the data flow task executes.
Second issue is when you disable the package configurations in the child, the parent doesn't recognize that it's diables and tries to load the configurations.
It's almost like there are some settings in a child that get ignored by the parent??
Anyone else experience this?
thx

Has someone managed to pass successfully a variable from a parent package to a child package? I€™ve tried a zillion permutations and I can€™t get it to work. The strange thing was that I was able to successfully do this with pre-RTM builds. Basically, what I am trying to do is:
The parent package has a variable, e.g. ExecutionID which I set using a script to System::ExecutionInstanceGUID. I verified that the variable is set correctly by dumping it to a SQL Server table.
I created a child package variable with the same name.
In the child package, I€™ve created a parent package configuration that points to the ExecutionID variable.
I am trying to read the variable in a Derived Column Task in which I have a column linked to @ExecutionID.
This doesn€™t work. Step-by-step instructions from someone who managed to concur this will be greatly appreciated.
Oh, I didn€™t have any luck hitting a breakpoint in a script task inside a child package with both in and out of process execution also.

Hi,
I having a problem getting the child package variable values into a parent package. Here is the scenario;
I have parent package(Master) calling two child packages using execute package task. I have no problem to pass variable values from the parent to child using the parent configuration but not able to get the variable values from the child to parent. I am setting the package status in each child package based on certain conditions and determine the final status in a parent based on child package variable statuses. Does any body have any idea? I will appreciate your thoughts.Thanks..Mako

Hi,
I have a child package running under main parent pakage.
I am passing value of integer & string type variables from parent package to child package's variables ( as disscussed in following artical http://msdn.microsoft.com/en-us/library/ms345179(SQL.100).aspx) ,values assigned in child package variables are futher used to build connection string for flat file connection manager in child package.
I have been using this whole SSIS package sucessfully for last three months,but suddenly the following error arises
"OnError,,,,,,,The result of the expression
Code Snippet
"@[User::StrTextFileImpDirectory] +"SomeTextStringHere"+ @[User::StrANTTextFileName] +(DT_STR,30,1252) @[User::Staging_Date_Key]+ "SomeTextStringHere"
on property "ConnectionString" cannot be written to the property. The expression was evaluated, but cannot be set on the property."
When I see the result of above mentioned expression through Log file than it appears that my string variable
Code Snippet"@[User::StrTextFileImpDirectory]
in child package has not been populated with any value from parent package variable, I.e it has been populated with empty string(While this is not desired value).
Same problem arises with my integer type variable
Code Snippet@[User::Staging_Date_Key]
,it has ben populated with value zero (i.e default value at design time for integer type),while this is not desired value.
Can some one guide me how to figure out the cause for error....
Is it possible that such kind of error may arise due to any change in enviornment of server....
