Integration Services :: DefaultBufferMaxRows - Is It Determined By Row Length Of Data Flow Task Source Or Destination

Oct 18, 2015

We have a single generic SSIS package that is used to import several hundred iSeries tables into SQL. I am not looking to rewrite the process. But I am looking for ways to improve performance.

I have tried retain same connection, maximum insert commit size, lock table (tablock), removed some large columns, played with the log file location and size, and now I am working to tweak the defaultbuffermaxrows.

To describe the data flow task - there are six data flows tasks (dft)  working at the same time. Each dtf has their own list of iSeries tables and columns and the corresponding generic SQL table names. Each dtf determines their list of tables based on the number of columns to import. So there is dft30 (iSeries table has 1-30 columns to import), dtf60 (iSeries table has 31-60 columns to import), etc. The destination SQL tables are generically called Staging30, Staging60, etc. Each column in the generic Staging tables are varchar(100). The dtfs are comprised of an OLE DB Source and an OLE DB Destination.

The OLE DB Source uses a SQL Command from Variable to build a SELECT statement. The OLE DB Source uses a connection manager that uses an IBM iAccess IBMDA400 provider.  The SQL Command ends up looking like this for the dtf30. This specific example is importing from the iSeries table TDACLR and it only has two columns so it will be copied to the Staging30 table.

select TCREAS AS C1,TCDESC AS C2,0 AS C3,0 AS C4,0 AS C5,0 AS C6,0 AS C7,0 AS C8,0 AS C9,0 AS C10,0 AS C11,0 AS C12,0 AS C13,0 AS C14,0 AS C15,0 AS C16,0 AS C17,0 AS C18,0 AS C19,0 AS C20,0 AS C21,0 AS C22,0 AS C23,0 AS C24,0 AS C25,0 AS C26,0 AS C27,0 AS
C28,0 AS C29,0 AS C30,''TDACLR'' AS T0 from Store01.TDACLR

The OLD DB Source variable value looks like the following, but I am not showing the full 30 columns

select cast(0 AS varchar(100)) AS C1,cast(0 AS varchar(100)) AS C2,cast(0 AS varchar(100)) AS C3,cast(0 AS varchar(100)) AS C4,cast(0 AS varchar(100)) AS C5, ... cast(0 AS varchar(100)) AS C30.

The OLE DB Destination uses OpenRowSet Using FastLoad From Variable. The insert into Staging30 ends up looking like this.

insert bulk STAGE30([C1] varchar(100) ,[C2] varchar(100) ,[C3] varchar(100) ,[C4] varchar(100) ,[C5] varchar(100) , ...  ,[C30] varchar(100) ,[T0] varchar(20)

Of course we then copy and transform the Staging30 data to the SQL table that equals T0.

But back to defaultbuffermaxrows. Previously the dtfs had default values of 10000 for DefaultBufferMaxRows and 10485760 for DefaultBufferSize. I added a SQL task to SUM the iSeries column sizes, TCREAS and TCDESC in this example, and set the DefaultBufferMaxRows by dividing the SUM of the columns max_length into 10485760. But I did not see a performance improvement. Do you think that redefining the columns as varchar(100) for the insert is significant? Should I possibly SUM the actual number of columns (2) as 2x100 or SUM the 30x100?

Data Flow Task - OLEDB Source / Destination

Nov 9, 2006

Hi

Inside a data flow task, i have a oledb source and destination. In my situation, I need to pull data from a table in the source, but also hard code some columns myself, which means my source is a blend of data from table, hard coded data, which will then have to be mapped to columns in oledb destination. Does anyone which option to choose in the oledb source dropdown for the data access mode. Keep in mind, i do need to run a a select query, as well as get data from a table. Is it possible to use multiple oledb sources and connect to one destination, because that is really what intend to do here. I am not sure how it will work, or even if its possible. Basically my source access mode needs to be a blend of sql command and table columns, how would that be implemented? Any help or advice is appreciated.

SQL Integration Services Data Flow Task Slows Down

Dec 7, 2007

We are using an OLE DB Source for the Data Flow Source and OLE DB Destination for the Data Flow Destination. The amount of data being moved is about 30 million rows, and it is gather using a sql command. There is not other transformations in between straight from one to another. The flow starts amazingly fast but after 5 million rows it slows considerably. Wondered if anyone has experienced anything similar with large loads.

Integration Services :: SSIS - Can Use Variables In A Data Flow Task Command

Jul 2, 2010

In my SSIS Data Flow Task, I have a query that retrieves data based on a couple of date parameters. Is there a way we can pass/use the Variables defined in the SSIS package in the query ?

(I am assigning values to those variables from C# code)

The query should look like this:

select ordernumber, customerid from salesorder

Integration Services :: Data Flow Task Flat File Connection

Apr 29, 2015

I have a Data Flow Task within a ForEach loop container.  The source of the flow is ADO.NET connection and the destination is a Flat File Connection.  I loop through a collection of strings in the ForEach loop.  Based on the string content, I write some data to the same destination file in each iteration overwriting the previous version. I am running into following Errors:

[Flat File Destination [38]] Warning: The process cannot access the file because it is being used by another process.
[Flat File Destination [38]] Error: Cannot open the datafile "Example.csv".
[SSIS.Pipeline] Error: Flat File Destination failed the pre-execute phase and returned error code 0xC020200E.

I know what's happening but I don't know how to fix it.  The first time through the ForEach loop, the destination file is updated.  The second time is when this error pops up.  I think it's because the first iteration is not closing the destination file. How do I force a close of the file within Data Flow task or through a subsequent Script Task.This works within a SQL 2008 package on one server but not within SQL 2012 package on a different server.

Integration Services :: Check Table For Existing Record Before Data Flow Task

Jun 1, 2015

Using SSIS 2012 (within Visual Studio) on Windows 7.

Before allowing my Data Flow task to fire, I'd like to check the target table (OLE DB Destination) for a specific date value in a specific field. I've seen how the Lookup Task is commonly used to check for dupes before inserting, but I'm not able to use that method because the data value I want to search the table for is contained in a Global Variable (let's say "MyVariableDate"). 

Is there any way to check for any records in a target table where Date1 = MyVariableDate (i.e. scanning the entire table for any occurrence of MyVariableDate in the Date1 field)?

How To Retrieve Connections Collection Inside Custom Data Flow Tasks (source/destination)

May 16, 2008

Hi,

How do I retrieve the connections (connection managers) collections from Custom Data Flow destination? ComponentMetadata.RuntimeConnectionCollection is empty. I would like to be able to access all the connections defined in the package from the custom data flow task.


I came across code in which it was possible to access the Connections collection using the IDtsConnectionService for custom task (destination). The custom task has access to serviceProvider, whcih can be used to get access to the IDtsConnectionService interface but not the custom data flow task.


Any help appreciated.

Parameters In Data Flow Task With Oracle Database Source

In many DTS packages I have used parameterised queries for incremental loads from Oracle database sources using the Microsoft ODBC Driver for Oracle.

Now I want to migrate these packages to SSIS, but the OLE DB connection for Oracle does not support parameters.

I cannot use the "SQL command from variable" data access mode because of the 4000 character limitation on the length of string variables and expressions.

Am I missing an obvious workaround?

Integration Services :: File System Task Move Directory Deletes Parent Destination Folder

Mar 12, 2013

I attempted to use Move Directory to move the contents of one directory to another.  I encountered the 'different volume' issue that others have experienced.  While this error is frustrating I can work past this particular issue. My more pressing question is why is the move directory command overwriting a destination directory?  

When I setup the Move directory file task I provided two vars to hold src and dest location:

dest var:  estserveroutput
src var: devserverdev estfiles
Set overwrite destination = TRUE

Why would Move Directory overwrite output folder at destination?  Shouldn't it only overwrite if the testfiles directory exists at destination?  This is very frustrating since I cannot find enough information in the official documentation to understand what is happening here.  

Is it just me or does the documentation for Move directory seem.....incomplete?

Integration Services Data Types Maximum Length

Apr 17, 2007

Hi,

Is there a way in-code to determine the maximum length of a Integration Services Data Type.

I need to determine based on the data type what the maximum length of a column is IN-CODE.

However, the column.Length property only gives me a length for DT_WSTR and DT_STR values. This is the only property that would seem to remotely give me the right answer.

I need to know the maximum lengths in columns for DT_BOOL, DT_CY, DT_I2, DT_I4, DT_I8, DT_NUMERIC, and DT_UI1. I can always hard-code these values into my program, but that makes no sense. There has to be some sort of way to determine what the maximum possible length of these values are.

For numeric values I could use the column.Precision value but that still leaves with with a lot of data types without a maximum length.

Bulk Insert Vs. Data Flow Task (different Row Results Using Flat File Source)

Nov 2, 2006

I'm importing a large csv file two different ways - one with Bulk Import Task and the other way with the Data Flow Task (flat file source -> OLE DB destination).

With the Bulk Import Task I'm putting all the csv rows in one column. With the Data Flow Task I'm mapping each csv value to it's own column in the SQL table.

I used two different flat file sources and got the following:

Flat file 1: Bulk Import Task = 12,649,499 rows; Data Flow Task = 4,215,817 rows
Flat file 2: Bulk Import Task = 3,403,254 rows; Data Flow Task = 1,134,359 rows

Built In Limit Or Setting That Limits The Number Of Rows From An OLE DB Source Table In A Data Flow Task?

Feb 16, 2007

I have a table that I'm loading as part of a control flow that in turn is copied to a target table by using a data flow task. I am doing this because a different set of fields may be used from the source entry to create the target entry based on a field in the source table. That same field may indicate that multiple entries need to be created in the target table from one source table entry for which I use a multi-cast transformation.

The problem I'm having is that no matter how many entries there are in the source table, the OLE DB Source during execution only shows 7,532 entries being taken from the source table. If there are less than 7,532 entries in the source table, everything processes fine. More than 7,532 and the data flow task only takes 7,532 and then seems to hang. It also seems as though only one path of the multi-cast transformation is taken when the conditional split directs a source entry down that path.

Seems like a strange problem I know, but any insight anyone could provide is appreciated. Thanks.

Integration Services :: Using Sensitive Project Parameters In Data Flow Tasks

Feb 11, 2014

I have a requirement to read an encrypted file as a data source. I am not allowed to save an unencrypted text file version on disc  at any time for any length of time, therefore I created a custom source component that reads an encrypted csv file, decrypts it, and then passes each row of data to the pipeline and ultimately to an ole data destination. Basically it is just a text file reader with an added class that adds functionality that decrypts the file before the component sets columns or reads rows. 

The custom component, “Encrypted File Source”, has a custom property “encryptionkey” with the encryption required flag set to true (code below) and is declared as eligible to be set in the expressions.

IDTSCustomProperty100 EncryptionKey = ComponentMetaData.CustomPropertyCollection.New();
            EncryptionKey.Name =
"EncryptionKey";
            EncryptionKey.Description =
"Secure String key value to decrypt the file";
            EncryptionKey.Value =
string.Empty;
            EncryptionKey.ExpressionType =
DTSCustomPropertyExpressionType.CPET_NOTIFY;
            EncryptionKey.EncryptionRequired =
true;

I want to be able to set the password for the encrypted file in the SQL Agent job that executes the SSIS project. This means I have an environment with a variable, “DataPassword”, that is set to sensitive.  It maps to a Project parameter in the SQL Agent job that is also set to sensitive.  And I now I want to access that sensitive Project Password inside my data flow, specifically in the Encrypted File source task that I created and set my EncryptionKey to that Project Parameter. 

The problem is that SSIS says. 

"expression cannot be evaluated.  ... The Expression will not be evaluated because it contains sensitive parameter value "$Project::DataFilePassord" . Verify that the expression is used properly and that it portects sensitive information"
((Microsoft.DataTransformationsServices.Controls) "<v:shapetype coordsize="21600,21600" filled="f" id="_x0000_t75" o:preferrelative="t" o:spt="75"
