Tips For Optimizing A SSIS Package
Jan 18, 2008
Hi,
I have a SSIS package that reads a text file and generates an output file out of it after transformations.
Now, a 20MB text file (containing about 50,000 records) is taking around 5 mins to complete.
There is a Data Flow Task which is taking the major chunk of the time.
It contains the following:
1) File Source
2) Conditional Splits (2 in number)
3) Derived Column
4) Data Conversion Transformation
5) OLE DB Destinations (3 in number)
The number of records being processed is close to 50,000
Please share your tips for optimizing the package.
Thanks in advance.
Regards,
B@ns

Hello everyone!
I've got a problem with a real slow query, I would be very happy if somebody has any idea to improve the speed of it...
The idea is to get the top 2 products, a customer hasn't bought wich are in his interest...
query (simplificated)
-------------------------------------------------
SELECT TOP 2 prodID, Title, Price FROM bestSold7Days WHERE
prodID NOT IN (SELECT prodID FROM orders INNER JOIN orderProducts ON orders.orderID = orderProducts.orderID WHERE (orders.custID=394))
AND
(prodType = COALESCE((SELECT TOP 1 products.prodID FROM orders INNER JOIN orderProducts ON order.orderID = orderProducts.orderID INNER JOIN products ON orderProducts.prodID = products.prodID WHERE (orders.custID=394) GROUP BY products.prodType ORDER BY SUM(orderProducts.PCS) DESC), 2))
-------------------------------------------------
end query
(COALESCE is for replacing if the customer hasnt ordered anything, or hasnt ordered anything of this type)...
Thanks for any time spent!

Hey, I've a few jobs which call SSIS packages. If I run the SSIS package, it runs fine but if I try to run the job which calls this package, it fails. Can someone help me troubleshoot this issue? None of my jobs that call an SSIS package work. All of them fail.
Thank you

Hi,
In our project we have two SSIS package.
And there is a task (Execute SSIS package) in First package that calls the execution of second package.
I m continuously receiving an error "Failed to decrypt protected XML node "PackagePassword" with error 0x8009000B "Key not valid for use in specified state.". You may not be authorized to access this information. This error occurs when there is a cryptographic error. Verify that the correct key is available."
As we are running first package by job, job runs successfully logging above error
The protection level of second package is set to "EncryptSensitiveWithUserKey"
Can anybody please suggest how to handle it?

I have a SSIS job, one of the last steps it performs is to execute a SQL 2000 DTS package. This has to be done as a SQL 2000 DTS package as it is performing rebuilds of SQL 2000 Analysis Services dimensions and cubes. We've found that when the DTS fails the SSIS job is happily completing showing as a success, we would prefer to know it went wrong.
As far as I'm aware SSIS merely starts the DTS off and doesn't care about it's result. I've taken a look in to turning on the logging for the execute DTS package and thought that the ExecuteDTS80PackageTaskTaskResult would give me the answer I need...but is merely written to the log not available as an event-handler. It also looks like it is not safe to put a SQL task in as the next item to go look at the SQL 2000 system tables to look at the log for the DTS package as the SSIS documentation warns that the DTS package can continue to run after the execute DTS package task has ended.
Ideally I want any error raised within the DTS package to cascade up to be an error in the SSIS job, I can then handle it appropriately. I cannot find a way to do this. Is there a way?
If not, can anyone suggest how in the remainder of the SSIS tasks I can be sure that the DTS has completed before I start any other tasks that will check for the SQL 2000 log of its execution?

Hi All,
I am in the process of moving from a 32-bit SQL Server 2005 Enterprise (9.0.3054) to a 64-bit SQL Server 2005 Enterprise (9.0.3054 with 4 CPUs and 8GB of memory on Win 2003 SP2) and the process has been very frustrating to say the least. I am having a problem with packages that I created on my 64-bit SQL Server. I am importing a few tables from the 32-SQL Server into the 64-bit SQL Server using the Task --> Import to create the package.
Sometimes when I am creating a package I get the following error in a message box:
SQL Server Import and Export Wizard
The SSIS Runtime object could not be created. Verify that DTS.dll is available and registered. The wizard cannot continue and it will terminate.
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. (System.Windows.Forms)
Other times when I run a package that has run successfully before I get the following error:
Faulting application dtexecui.exe, version 9.0.3042.0, stamp 45cd726d, faulting module unknown, version 0.0.0.0, stamp 00000000, debug? 0, fault address 0x025d23f0.
Other times I get this error message:
.NET Runtime version 2.0.50727.1433 - Fatal Execution Engine Error (79FFEE24) (80131506)
And still other times
The package appears to hang when running. By this I mean that the Package Execution Progress shows progress up to a point then it just stops. (The package takes about 17 seconds to run normally) CPU usage is at 1% and the package cannot be stopped.
I have deleted and re-created the package several times and I have also re-installed the service pack on the SQL Server (9.0.3054) but that did not help.
Does anyone have any other suggestions to try?
Thanks.

I would like to standardize SSIS development so that developers all start with the same basic template. I have set it up so it is an available template ( http://support.microsoft.com/kb/908018 ) but I would like it to be the default when a new project or package is created. Is this an option?

Hi there
We have a SSIS run which runs as follows
The master package has a configuration file, specifying the connect strings
The master package passes these connect-strings to the child packages in a variable
Both master package and child packages have connection managers, setup to use localhost. This is done deliberately to be able to test the packages on individual development pc€™s.
We do not want to change anything inside the packages when deploying to test, and from test to production. All differences will be in the config files (which are pretty fixed, they very seldom change). That way we can be sure that we can deploy to production without any changes at all.
The package is run from the file system, through a job-schedule.
We experience the following when running on a not default sql-server instance (called dkms5253uedw)
Case 1:
The master package starts by executing three sql-scripts (drop foreign key€™s, truncate tables, create foreign key€™s). This works fine.
The master package then executes the first child package. We then in the sysdtslog get:
Error - €ścannot connect to database xxx€?
Info - €śpackage is preparing to get connection string from parent €¦€?
The child package then executes OK, does all it€™s work, and finish. Because there has been an error, the master package then stops with an error.
Case 2:
When we run exactly the same, but with the connection strings in the config file pointing to the default instance (dkms5253), the everything works fine.
Case 3:
When we run exactly the same, again against the dkms5253uedw instance, but now with the exact same databases defined in the default instance, it also works perfect.
Case 4:
When we then stop the sql-server on the default instance, the package faults again, this time with
Error - €śtimeout when connect to database xxx€?
Info - €śpackage is preparing to get connection string from parent €¦€?
And the continues as in the first case
From all this we conclude, that the child package tries to connect to the database before it knows the connection string it gets passed in the variable from the master package. It therefore tries to connect to the default instance, and this only works if the default instance is running and has the same databases defined. As far as we can see, the child package does no work against the default instance (no logging etc.).
We have tried delayed validation in the packages and in the connection managers, but with the same results (error).
So we are desperately hoping that someone can help us solve this problem.
Thanx,
/Nils M - Copenhagen

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?

Deployed Report having SSIS package as source do not work when Indirect Package configuration is used in ETL package. It seems ETL package when called/executed from Report manager does not recognize environment variable to pick up the dtsconfig file.
The Report works when Direct package configuration is used to same dtsconfig file.
What could be the reason? Any solution for this? This will cause our build/deployment to QA and Prod very difficult.

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?

Hi,
I am making use of the DtUtil tool to deploy my package to SQL Server.
Following is my configuration:
32-bit machine and 32-bit named instance of Yukon.
I have some package variables which need to be set in the code.
Previously I did it as follows:
Set the package variables in the code. For example:
pkgFile.Variables["User::DestinationServerName"].Value = <myvalue>
Deploy the package as follows:
applnObj.SaveToSqlServer(pkgFile, null,
destinationServer, null, null);
Here the package was successfully deployed and when i open those packages using BIDS, I am able to see that the variables are set to the values as doen in teh code.
Because of oen problem I am not using SaveToSQLServer method. So I switched to DTUtil tool.
Now I am doing it this way:
Set the package variables as before.
Deploy the package to SQL Server using DTUtil tool.
Now is the problem:
The package is successfully deployed. But the variables are not set to the value that I have specified in the code.
I also tried DTexec utility to set the package variable. Even that does n't work.
Can anyone help me out? Is there any alternate method to set package variables?
Thanks,
Sandhya

I want to achieve the following in (SSIS/SSDT for SQL 2012) -Â
I have a generic SSIS package which simply sends out email notifications using SMTP email task (this package is within its own project, and has project level input parameters).
I need to be able to call this package in the Event handler section of every package (numbering in about less than 60) that we have. These packages are within their own respective projects.
I thought I could use the "execute package task", but it turns out , using this, I cannot call a package that is part of some other project. I also cannot call a package that is stored in the CATALOG. Is there any way I can do this ?
When I call the child package , I should be able to send in parameters like - error information and package name of the Parent package.

I have an SSIS package (TransAgentMaster) that I recently modified to include a call to a child package via the file system. The child package creates a text file. When I run the package in dev studio then the child package/text file is produced.
I then imported the TransAgentMaster as a stored packagesfilesystem package into SQL SSIS and executed the package. The child package produced the text file.
I then ran the SQL Server Agent to see if the child package would work and it did not generate the text file. Thus after updating a SSIS package importing the package into SSIS the job that calls the package will not call the child package. Please not that the TransAgentMaster package calls 7 children packages €¦ just not my new one.
Any thoughts why the agent will not run the child newly crated childe package?

Dear all,I'm designing a system including the database and the securityrepresents the most crucial aspect of the system; hence for thedatabase security i have implemented the following aspects and needyour advise on further aspects or perhaps corrections where by thesystem is web based using asp.net and under iis 6.0 with https; in theasp.net engine side, i have included client-side validations for whatever is inputed and validated against sql injections for postbackforms:The features of security in SQL Server 2005 side i have implemented:1.) Created MACHINEASPNET Account2.) Allowed ASPNET Account to access the DB3.) Explicity denied ASPNET Account all permissions to all tables,functions and views4.) Denied all permissions to the ASPNET user for stored proceduresexcept EXECUTE permissions5.) By Stored procedure creation, WITH ENCRYPTION, EXECUTE AS'MACHINEASPNET' was usedNo SQL was included in the asp.net code except for calling storedproccedures; the policy is to only call stored procedures within theasp.net pages and encrypt the connection strings inside the web.configfile.Kindly, give me some guidelines for better security or discuss with methe security aspects i mentionedRegards

Hi all:
I'm new to replication but I have already set up replication and have seen it
working and failing and have gotten myself out of jams so far but there must
be an easy way to administer it when things don't replicate as expected. I'm
finding that I could easily kill half a day just trying to dig up
information leading to troubleshooting tips. Is there documentation just on
managing this feature. The regular MS Administrator's guide doesn't offer much.
Currently I have a problem that if replication fails on one command I get a
SQL Mail telling me of the problem but does replication continue to the next
command or does it just stop until the problem is fixed? I'm finding that I am
constantly checking the publisher and subscriber databases and verifying if
replication is indeed doing what the msjob_commands table reports. I set the
batch to commit after each transaction instead of every 100.
Help...

Hello,
We come accross situations where people are running big updates on the database (i.e. 50.000 updates).
Our problem is that those big updates are blocking other user updates.
Thanks to snapshot isolation, users can query (select) the database with no lock.
We rebuilt the indexes setting that the indexes used by the update procedure would not use page locks and only row locks.
We set that the database would update the statistics asynchronously.
Now we are still facing blockings and we would like to optimize the database to avoid those blockings.
What else could we check? Any tips regarding the way to avoid that problem is really welcome.
Thanks,
Olivier

I was planning to disbablethe default gateway on one or maybe disabling file sharing on both, iwas also thinking to block access to the the terminal server that isrunning in admin mode, either through the firewall or the permissionsof the rdp protocol. I have a few admins that have account manager andserver operator permission as well as exchange admin. Any ideas in howto restrict access to my servers? thanks.

Dear Friends,
I store several configurations in the main database of my SSIS packages. I need to get the servername from a xml or txt file in order to get those configurations stored in my database.
How you think is the better way to do that?
Using a FlatFileSource to read the file and a script to save the value into a SSIS variable?
Using the package configuration I cant do that... maybe I dont know, but I can save the SSIS variale in the configuration file, but what I need is to do the inverse, read the configuration file and save the value in the SSIS variable.
How the best way you suggest?!
Regards!!
Thanks.
