Data Flow Stuck In Phase The Final Commit Data Insertion Has Started
Jun 19, 2007Hello,
I have noticed that for one of my data-flows, the process is really long during the phase "the final commit data insertion has started".
To be accurate, the process is fast until it reaches this phase. It happens often when I load millions of lines.
The extraction is done from a database SQL Server 2005 to a database SQL Server 2005, on the same server (with the SQL Server native provider).
I used a SQL Server destination but I have tried with an OLE DB destination and it is the same situation.
Why the process could be so long during this phase?
There is a way to optimised my package to avoid that?
Any idea is welcome.
Thanks.
Guillaume
Can Anyone Explain What The Pre-execute Phase Is Doing For OLE DB Data Sources Using Sql Commands?
Nov 3, 2006I have a project which spans multiple servers and aggregates literally billions of rows of data into a much smaller and manageable result set which I store on another server. There are two stored procedures which take up 99.9% of the processing time. Each one of these SPs are estimated to run over 3 hours a piece (gives you an indication of how much data there really is). With in this SSIS package, I have two control flows, one for each SP. When I run the SSIS package from VS2005, I can see that there is a pre-execute phase which takes about an hour abnd a half to complete, and then move on to executing. My question is, what the heck is this, and what is it doing? I know it validates the sql in the procedure, but does it actually run the SP during that pre-execute phase? If it does, is there any way to get around that?
Any help would be appreciated.
Difference Between The Fuzzy Lookup And Fuzzy Grouping In Ssis
Aug 14, 2007Dear Friends,
i think fuzzy lookup
COMPARES WHAT WE ARE MAPING THE COLUMNS WITH SPELLING (IT WILL REJECT ATLEAST 1 LETTER IS DIFFRENT IN ANY RECORD MAPPED COLUMN) EX: RAVI != REVI
what is fuzzy grouping ???? please explain

Performance Expectations For Fuzzy Lookup Against 25mill Row Lookup Table
Oct 31, 2007We did some "at scale" fuzzy lookup tests today and were rather disappointed with the performance. I'm wanting to know your experience so I can set my performance expectations appropriately.
We were doing a fuzzy lookup against a lookup table with 25 million rows. Each row has 11 columns used in the fuzzy lookup, each between 10-100 chars. We set CopyReferenceTable=0 and MatchIndexOptions=GenerateAndPersistNewIndex and WarmCaches=true. It took about 60 minutes to build that index table, during which, dtexec got up to 4.5GB memory usage. (Is there a way to tell what % of the index table got cached in memory? Memory kept rising as each "Finished building X% of fuzzy index" progress event scrolled by all the way up to 100% progress when it peaked at 4.5GB.) The MaxMemoryUsage setting we left blank so it would use as much as possible on this 64-bit box with 16GB of memory (but only about 4GB was available for SSIS).
After it got done building the index table, it started flowing data through the pipeline. We saw the first buffer of ~9,000 rows get passed from the source to the fuzzy lookup transform. Six hours later it had not finished doing the fuzzy lookup on that first buffer!!! Running profiler showed us it was firing off lots of singelton SQL queries doing lookups as expected. So it was making progress, just very, very slowly.
We had set MinSimilarity=0.45 and Exhaustive=False. Those seemed to be reasonable settings for smaller datasets.
Does that performance seem inline with expectations? Any thoughts to improve performance?
Fuzzy Lookup Error When Adding Additional Lookup Columns
Sep 26, 2007I'm working with an existing package that uses the fuzzy lookup transform. The package is currently working; however, I need to add some columns to the lookup columns from the reference table that is being used.
It seems that I am hitting a memory threshold of some sort, as when I add 3 or 4 columns, the package works, but when I add 5 columns, the fuzzy lookup transform fails pre-execute:
Pre-Execute
Taking a snapshot of the reference table
Taking a snapshot of the reference table
Building Fuzzy Match Index
component "Fuzzy Lookup Existing Member" (8351) failed the pre-execute phase and returned error code 0x8007007A.
These errors occur regardless of what columns I am attempting to add to the lookup list.
I have tried setting the MaxMemoryUsage custom property of the transform to 0, and to explicit values that should be much more than enough to hold the fuzzy match index (the reference table is only about 3000 rows, and the entire table is stored in less than 2MB of disk space.
Any ideas on what else could be causing this?
Lookup Task Data Flow Transformation Causes Data Flow Task To Hang?
Dec 28, 2007Hi,
I'm trying to implement an incremental data pull (Oracle to SQL) based on Andy's blog:
http://sqlblog.com/blogs/andy_leonard/archive/2007/07/09/ssis-design-pattern-incremental-loads.aspx
My development machine is decent: 1.86 GHz, Intel core 2 CPU, 3 GB of RAM.
However it seems the data flow task gets hung whenever I test the package against the ~6 million row source, as can be seen from these screenshots. I have no memory limitations on the lookup transformation. After the rows have been cached nothing happens. Memory for the dtsdebug process hovers around 1.8 GB and it uses 1-6 percent of CPU resources continuously. I am not using fast load to insert new records into my sql target table. (I am right clicking Sequence Container 3 and executing this container NOT the entire package in the screenshots)

http://i248.photobucket.com/albums/gg168/boston_sql92/7.jpg
http://i248.photobucket.com/albums/gg168/boston_sql92/8.jpg
The weird thing is it only takes 24 minutes for a full refresh of the entire source table from Oracle to the SQL target table.
Any hints,advice would be appreciated.
Advanced Lookup In A Data Flow

A01 Handicap features
B22 Smoke-Free
F09 Tinted Windows
C13 Picnic Area
C24 Extra Storage

1 Handicap features, Smoke-Free, Tinted Windows
2 Picnic Area, Extra Storage, .....
3 Tile Flooring, Central Airconditioning, .....
How can I do this in a data flow - any ideas???
One-time Data Flow Lookup
Jan 15, 2007(Just getting started with SSIS) I have a data flow task with source S1 and destination D. The mappings from S1 to D are straightforward, but additionally, I need to lookup a value from source S2 one time and map the value a column in D for every row of S1. Note that this lookup based on a constant value independent of S1, and therefore no column mappings are involved (this lookup is essentially "standalone").
I would expect I could do the lookup, assign the value to a data flow level variable, then reference that variable in a derived column transform or some such thing, but I'm having trouble figuring out how to do the lookup in the data flow task and assign it to a variable. Am I on the right track here, or...?
Pre-Execute Phase
May 23, 2006What happens during the pre-execute phase?
Is there anything I can do to optimize it's execution?
I have a package that takes data from 2 SQL Server sources, unions them, and writes to a sql table.
The pre-execute takes 20 minutes, and the execution takes 45 seconds.
Thanks

Long Duration Pre-Execute Phase
Mar 2, 2006Does anyone know why SSIS sometimes just sits in the Pre-Execute phase of a data flow and does nothing? It doesn't matter how elaborate the data flow is or the volume of data. It can sometimes take 80% of the task's run time.

Load Fact Table, Very Slow With Lookup - Data Flow Transformation
Apr 9, 2008
Hello,
I have developed some packages to load data into "Fact" tables in the data warehouse.
Some packages are OK, other ones not. What is the problem?: some packages load fact tables with lots of "Lookup - Data Flow Transformation" into the "data flow task" (lookup against dimension tables) but they are very very slow, too much slow to be choosen as a solution.
Do you have any other solutions to avoid using "Lookup - Data Flow Transformation"? Any other solution (SSIS, TSQL and so on....) is welcome to speed up the Fact table loading process.
Thank in advance
DTS Execute SQL Task Freezes
Nov 15, 2004Hi all !
Hi have a package with 3 steps :
1 - import data from flat file into a temp table
2 - copy selected data from the temp table to permanent tables
3 - truncate temp table
The task #2 is a SQL statement
INSERT INTO MODELS (MODEL_ID)
SELECT DISTINCT MATNR
FROM STANDARD
WHERE MATNR NOT IN (SELECT MODEL_ID FROM MODELS)
where STANDARD is the temp table and MODELS a permanent one. My problem is this simple task freezes all the time. It stalls on 'Starting' and stays in this state forever when I execute the package.
Any idea why ?

Package Stuck On Pre-Execute Phase Is Beginning.
Jun 8, 2007Hi all,
I have a monster SQL query (SQL Server connection) that I'm trying to export to flat file. My package appears to just stick on the "Pre-Execute phase is beginning" stage. (I left it running overnight, and it's still going... no error message, I think it's just hung. If I include a "Top 10" in the my source query it completes without a problem. I'm wondering if it's an out-of-memory issue, but when I've run into this in the past there have been error messages generated. I've tried using both a Data Reader and an OLEDB Datasource. Does anyone have any ideas of what's going on and how I might fix it?
Thanks!!!Jess

Fuzzy Lookup
Feb 16, 2007Hi,
I am using a fuzzy lookup to cleanse data from a sales line details table, during the import process. The sales order line details contains a filed called 'reference' and this is compared to a field called 'category' in another table.
Using data viewers to check through the cleansing process, I notice that the fuzzy lookup doesn't seem to match i.e.
tbl.salesline.reference = 'I3' -> tbl.sales.category ='I03'
the above is OK, but the lookup also returns the following
tbl.salesline.reference = 'I9' -> tbl.sales.category ='I01'
The value I9 doesnt exist, and is miskeyed by user entry, and should have been 'I99'. I would have expected the fuzzy lookup to pickup the I99 value as at least two of the chrs are matching, but no, it picks the first 'I*' in the table.
If I expand the fuzzy lookup to return more results, i.e. 5 per record, then it returns the first 5 results....I01, I02 I03 and so on.
Is there a way of improving the fuzzy lookup itself?

Fuzzy Lookup And Case
May 25, 2007Hi,
Could someone please help!
Im doing a fuzzy lookup based on 3 fields (Surname/DOB/Gender). The only difference between the two sets of data is the case of the first letter of the Surname.
Reference table has "Stuart" Lookup has "stuart", I have set Fuzzy Lookup Input for Surname to Ignore Case but still it won't match.
The DOB/Gender are Exsactly the same.
Why does this not work? I there a work around?
Many Thanks, Deano

Multiple Fuzzy Lookup
Aug 31, 2006Is it possbile to have multiple fuzzy lookup within a data flow?
I need to have at least 3 fuzzy lookup in a data flow. Here're the conditions that I try to find match: 1=Zip&City, 2=Zip&State, 3=City&State. I've the first fuzzy lookup working fine. After that, I've a conditional split to get any unmatch, then use another fuzzy lookup for a second condition...at this point, I get the error saying "The package contains two objects with duplicate name of output column _Similarity..." I do not need to get the _Similarity and _Confidence, so is there a way to exclude them from returning in the output?
Any comments?
Thanks in advance.
Fuzzy Lookup Problems
Jun 16, 2006Hi everyone,
Ive just started looking at the Fuzzy Lookup feature and i think i must be getting something fundamentally wrong. I have two tables - each contain different meta data representations for a set of potentially similar documents. The only chance i have of matching a document in table A to a document in table B is a common title field. However, manual input means that the titles may differ in both tables although they are potentially quite similar in most cases.
In the lookup i get to specify the output columns from table B (Reference) which is fine, but i don't seem to get to choose the columns from table A that i would also like to see. So my output shows me all the documents from table B that it thinks are similar to ones in table A...but not identifying which record it's similar to.
I initially thought that the "pass through" columns that i identified would appear in the output - but this does not seem to be the case.
I must be using it incorrectly, but i have no idea how to progress with this apart from creating a new source table (C) which is a full outer join of table A and B - and then also using table C as the reference table, but that seems madness.
any help would be appreciated - ta

Fuzzy Lookup Questions
Nov 15, 2007Hi all
I've been doing some research and running some PoCs on using the Fuzzy Lookup Transformation (FLT) and had two questions:
1) When you choose to have a maximum of 1 output returned for each input, does FLT pick this output based on the best (highest) similarity and confidence scores or the first one it finds?
2) Why does FLT not support dynamically setting properties such as ReferenceTableName or MatchIndexName?
Any help or guidance with this is greatly appreciated.
Fuzzy Lookup No Columns Available
Apr 3, 2008I created a fuzzy transformation with an input table and a reference table. When I go to the Columns tab, there are no available input or lookup columns displayed. But if I select a different reference table, sometimes it works.
Are there any specific properties a reference table must have in order for columns to show up?
Thanks,

[Fuzzy Lookup [2601]] Error: An OLE DB error has occurred. Error code: 0x80004005. An OLE DB record is available. Source: "Microsoft SQL Native Client" Hresult: 0x80004005 Description: "Cannot create a row of size 8061 which is greater than the allowable maximum of 8060.".
Regardless of the changes I make I cannot get this to work and it would make a huge difference if I could get it to run.
Can I create the FuzzyLookupIndex on a SQL2K database?
Any help or advice would be greatly appreciated.
Many thanks

Does Fuzzy Lookup Work With Oracle ?
Apr 13, 2007
Sorry, this might be an obvious question, but I can not find anything in the documentation/forum.
I want to use a Fuzzy Lookup between 2 Oracle tables.
I select the Reference Table.
I then switch to the Columns tab, but the "Available Input Columns" and "Available Lookup Columns" lists are always empty.
I have experimented quite a bit, but to no avail. I noticed this on the Reference Table tabpage : "The table maintenance feature requires the installation of a trigger on the reference table". My guess would be that SSIS does not support Oracle for this, but I am not able to find anything in the documentation that it doesn't.
Any answer/pointer greatly appreciated.
Thanks
