Processing Mining Models && Structures Via SSIS
Dec 12, 2006
Still new to DM and SSIS...anyand all help is greatly appreciated!
In SSIS they say that you can use the Analysis Services Processing Task to process a mining model/mining structure, however, I do not see where you can give it a relational table to work off of. I know that I can use a data flow to do this but I wanted to go a different route if I could to process my models as I don't really necessarily need the data flow as what I am tring to do is pretty simple.
That brings me to a more general question, what is the best method for training your models using SSIS? I am building a new model everytime the package runs using some variables and the DDL task, running a query on it, and destroying it at the end of the package but I am having logistical problems training it outside of the data flow. I tried using the DM Query task but it requires that you output a result set and I am not sure if I can use it to create and process models.
I would think that they would just give you a DMX task similar to the SQL task but that does not seem to be the case. Also, when I browse the AS objects via the processing task I can only see the mining structures and not the mining models.
Am I just missing something here?
Cheers,
Dan Meyers

Hi!
If you make an view you can script it in SSMS and get the DDL.
How to do something similar with mining models/structures getting DMX?
I see you easy can get XMLA, but I would prefer the "dmx-ddl"...
Thanks

Hi, all here,
I am wondering where can I store my mining results in data mining engine? For example, I got mining results like accuracy chart, decision trees, and other formats of results based on different mining algorithms I used for my data mining, so where can I actually store the results for reporting service use later? Is it possible to do that in SQL Server 2005?
Thanks a lot for any help and guidance in advance.

I am in the process of creating an Integration Services package to automate the process of training mining models and getting predictions. Until recently, I have been processing the models directly from Business Intelligence Studio without any problems. However, when I try to use the exact same training set as an input to the Data Mining Model Training destination, I get several errors. Here is the output:
[Mining Models [1]] Error: Parser: An error occurred during pipeline processing.
[Mining Models [1]] Error: Errors in the OLAP storage engine: The process operation ended because the number of errors encountered during processing reached the defined limit of allowable errors for the operation.
[Mining Models [1]] Error: Errors in the OLAP storage engine: An error occurred while the 'CPT MODIFIER' attribute of the 'BCCA DMS ~MC-CLAIM LIN~5' dimension from the 'BCCA LRG DMS TEST' database was being processed.
[Mining Models [1]] Error: File system error: The record ID is incorrect. Physical file: . Logical file: .
[Mining Models [1]] Error: Errors in the OLAP storage engine: The process operation ended because the number of errors encountered during processing reached the defined limit of allowable errors for the operation.
[Mining Models [1]] Error: Errors in the OLAP storage engine: An error occurred while the 'BILL TYPE' attribute of the 'BCCA DMS ~MC-CLAIM LIN~5' dimension from the 'BCCA LRG DMS TEST' database was being processed.

[DTS.Pipeline] Error: The ProcessInput method on component "Mining Models" (1) failed with error code 0x80004005. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
I have not been able to find an answer as to why this is happening. I found a post regarding a similar problem with processing an OLAP cube in SSIS, but it seems that the author of that post never found an answer. Has anyone else here seen similar errors when processing mining models from Integration Services?
Also, if I process the mining models manually then try to run only predictions in SSIS, I get many of the same errors. I'll keep looking into the problem myself, but I would be very grateful if someone in this forum could shed some light on this issue.

Hi,
I have just run a simple data set through a model to predict a simple true or false value (i.e. binary output)
The Lift Chart/Mining Legend in Analysis Services shows three results €“ Score, Population Correct (%), and Predict Probability (%)
Population Correct I beleive is the percentage of predictions it got right out of the total number of predictions it tried to make. Is this correct?
However, I can€™t work out how the other two are derived in particular the 'SCORE'. To give a live example the scores were as follows:
Model Score Pop Correct Pred Probability
Decision Trees 0.83 76.59% 54.28%
Neural Network 0.75 67.63% 50.05%
Ideal Model 100.00%
Can anyone help with this and give a detailed explanation?
Many thanks,
S Rajput

Hi ,all here,
Thank you very much for your kind attention.
I just found that I am not able to view the accuracy chart for my mining model. The error message is: no mining models are selected for comparision. Which is quite strange.
Any guidance? thank you very much.
With best regards,

I am using the wizard to create a new mining structure and getting the error at the time of selecting the datamining technique like either microsoft decision tree or microsoft timeseries etc.,
"Unable to retrieve a list of supported data mining algorithms. Make sure you are connected to the correct Analysis Services server instance and the Analysis Services server named localhost is running and configured properly. You can continue with a default list of data mining algorithms."
What is that means?
Thanks in advance,

Hello
I've created models with Decision Tree and Neural Network algorithms that predict continous target. But I don't know how to interpret scores that occure under scatter accuracy plot. How should I interpret scores under scatter accuracy plot?
How can I estimate occuracy of model created with Time Series? How can I compare accuracy of model created with Time Series with models created with Decision Trees and Neural Network algorithms?
Thanks in advance.

Hi, guys,
Thanks for your kind attention.
Just want to make things perfectly work and make the most of our fantastic SQL Server 2005 Data Mining Engine. Can any of you here give me some super advices on the validation of the mining models. As we always see, the 3 aspects of a mining model are: Score, Population correct, and Predict Probability. So the question is: How can we combine these three aspects to best judge the mining models by being able to tell which model is the best one? And to what extent can we really trust these mining models?
These are very important before we can actually bring the models into work to convince other people who have no ideas what are going on with these models. Yes, we just want to convince them with the results of these models and make the most of them and best help them getting the most from their business operations etc.
By the way please can you explain a bit details on each of these aspects? Thanks again.
I am looking forward to hearing from you shortly and thanks bunch for your help.
With best regards,
Yours sincerely,

Hi, all here,
I am having a question about automating data mining models managements. As we know in many businesses, patterns vary very frequently, therefore, the mining models created will need to be created again afterwards according to new rules appearing in the data. But can we make all these process automated like automatically assessing the mining model accuracy and automatically recreate the mining models based on predifined specifications? Would please any one here give me any idea about that?
Thanks a lot for any guidance and help for that.
With best regards,

Hi, all,
Again I am confused about the extent of being convinced by the mining models. We can validate the models with accuracy chart, but then to what extent can we trust that? (you never get 100% correct miming models) If we dont trust the results of the models, then the patterns the models discover are meaningless.
Just need some advices from you experts here to help me convince people on what I got from my mining models.
I am looking forward to hearing from you shortly and thank you very much.
With best regards,

Hi, all experts here,
Thank you very much for your kind attention.
I got a strange problem with SQL Server 2005 data mining models though. I have selected the input columns for my mining model (which are different from the input columns for its mining structure, since I ignored some of the columns for the selected model). But the mining model still used all input columns from the mining structure rather than those I chose for the mining model.
Would please any one here give me any guidance and advices for that. Really need help for that.
Thanks a lot in advance for any help.

Hello!
I'll try to explain what I'd like to do. On my SQL Server 2005, SSAS contains a mining model (In fact a cluster one).
I'd like to show a detailed diagram build from this model on a web site. This diagram (and this is why I need automation) would depend on the user who's consulting it.
For example, a firm A will see the number of its customers in each cluster, and this information will be different for another firm B
So, I thought about several steps to perform:
1) Feed the model with the data for each firm
2) Build a Visio diagram from the previous data using the DM addins for Visio 2007
3) Generate HTML using the Visio export wizard
4) Publish HTML
And (important) this should be done automatically.
I made some experiments:
Step 1 is easy to perform with SSIS
Step 3 is also easy to do with the Visio SDK (using, among others, the exportAsHtml control) and Step 4 is trivial
I failed to perform stage 2, even with the SDK, since creating a diagram from a DM template requires the user to fill a wizard. By code, I'm able to create a document from a DM template, Drop a DM Stencil but when the wizard appears I'm unable to get a handle on it. And even if I was, I dunno if it would be a "clean" way of doing.
So my question is: first of all: isn't there an easier way to generate HTML from Mining Models automatically? And if my approach to this problem is the best (or the "least bad"), how to generate datamining Visio diagrams from code automatically?

Hi, all,
Another tricky confusion to me is that: many algorithms settings for the native algorithms in SQL Server 2005 Data Mining do not really significantly improve the results of those mining models with settings changes? (Apart from clustering algorithm setting of cluster number, by setting 0 as the number of clusters, the system will automatically cluster the data into clusters which I assume is the best way of mining the model with this method).
Any good advcies on this will be a lot appreciated.
I am looking forward to hearing from you shortly for this confusion and thanks a lot in advance.
With best regards,
Yours sincerely,

I am using BI Dev Studio for SS2005 in a research (as opposed to a production) environment. Often I want to compare the results of multiple models using the same attributes. If I switch to a different model, the Design view completely resets. Is there any way to retain the same field names with different models in the Design view?
My current workaround is to give my models similar names with AR, DT, CL, LOG, NN suffixes and make global changes in the DMX.
I have consulted the following without finding an answer:

Lets take the following example:
Movie train table:
ID Class
1 +
2 +
3 -
4 +
5 -
Actor train nested table:
ID MovieID Gender
1 1 F
2 1 M
3 1 F
4 1 F
5 2 M
6 2 M
7 2 F
8 3 F
9 3 F
10 4 M
11 4 M
12 4 F
13 4 F
14 5 F
15 5 M
We want to build a classifier model in order to predict the Class of a Movie based on the Gender of movie's actors. To deal with the nested table Analysis Services maps each record of the nested table to an attribute of the case table. These attributes are named Actor(n).Gender with n = 1..15, and so they are dependent on the nested table record numbers. Both Microsoft Decision Trees and Microsoft Naive Bayes algorihms use these attributes without any modification.
We are implementing a Relational Naive Bayes algorithm and we are planning to aggregate such attributes in order to make them independent of the nested table record numbers.
Next step we tried to predict some unseen cases and here we face with
a very huge problem.
Lets take more two tables of unseen cases:
Movie test table:
ID Class
6 +
7 NULL
8 NULL
Actor test nested table:
ID MovieID Gender
1 6 F
2 6 M
3 6 F
4 6 F
16 7 F
17 7 M
18 7 F
19 7 F
20 7 F
21 8 M
22 8 M
23 8 F
Predicting the movie 6 Class is not a problem since the movie actors were included in the training dataset and when the records are mapped to attributes because they already exist in the model. But when you
try to predict movies (7 an 8) with unseen actors all new attributes are simply ignored in the ALGORITHM:redict call (in_ulCaseValues is zero!) because they do not exist in the model!
What is the solution?

Hi all,
I have a very simple time series model which processing works fine without any problem. However when I run the following query
SELECT
[TimeSeries].[PriceChange],
[TimeSeries].[Symbol],
PredictTimeSeries(PriceChange, -3, 2)
From
[TimeSeries]
WHERE
[TimeSeries].[Symbol] = 'x'
I get the following error:
TITLE: Microsoft SQL Server 2005 Analysis Services
------------------------------
Error (Data mining): A time series prediction was requested with a start time further in the past than the internal models of the mining model, TimeSeries, specified in the HISTORIC_MODEL_GAP and HISTORIC_MODEL_COUNT parameters can process.
The following is the excerpt of the minding model script related to the two parameters:
<AlgorithmParameters>
<AlgorithmParameter>
<Name>MISSING_VALUE_SUBSTITUTION</Name>
<Value xsi:type="xsdtring">Previous</Value>
</AlgorithmParameter>
<AlgorithmParameter>

</AlgorithmParameter>
<AlgorithmParameter>
<Name>HISTORIC_MODEL_COUNT</Name>
<Value xsi:type="xsd:int">10</Value>
</AlgorithmParameter>
</AlgorithmParameters>
These HISTORIC_MODEL_GAP (1) and HISTORIC_MODEL_COUNT (10) should accommodate PredictTimeSeries(PriceChange, -3, 2). Could anyone shed some light on this?

I have installed the excel DM addin and am trying to work through the tutorials -
When I run the 'Analyze Key Influencers' tool against the sample data through a remote AS server I get:
The task was not able to detect any key influencers for the 'Purchased Bike' column. The values of 'Purchased Bike' seem unrelated to values of other columns.
however when I run it against a local AS server I get the expected results.
I can see no differences in settings or setup between the AS instances I am trying to use - perhaps a permissions issue?

Hello all,
I am having trouble trying to construct the following process in SSIS/SQL
2005:
1. Grab a set of unprocessed rows (ProcessDT = null) in an 'Action' table
2. For each of these rows, execute multiple stored procedures base on the
action type
If actiontype = 1, exec spAct1a @param1, @parm2
exec spAct1b @param1, @parm2, @param3, @param4
If actiontype = 2, exec spAct2a @param1, @parm2, @param3
exec spAct2b @param1, @parm2, @param3
etc....
3. Update ProcessDT so it's not processed again
4. Repeat until all rows are processed
Note - all sp params are contained in additional columns in the Action
table. Basically the Action table is a store for post-event processing of
sorts
but is order dependent, hence the row by row processing. And some of my
servers are 2000 so Service Broker is not an option (yet).
I first attempted to do this totally within the control flow - using an ado
recordset/foreach loop control, but I could not figure out how to run
conditional
process paths based on the ActionTypeID. I then tried to do this within the
dataflow using on OLEDB data source, a conditional split, and an oledb
command control
which almost got me there - the problem being for each row I need to execute
multiple sp's and it appears as if the oledb command only gives me one sp.
Any help would be appreciated!
Thanks in advance!

Hi,
I am facing some problem's while using the FOR loop container to execute 7-10 packages in parallel.
The main package has 7 FOR loop containers say F1-F7.
Each FOR loop container has 2 task's
T1==> exec child package C1
T2==> exec delay task Delay1.
The idea is to run child packages c1-c7 in parallel ...delay for some time and then run again since there are in the FOR loop container.
I am facing someproblems.
1. The execution of tasks T1-T7 is not guranteed. This means SSIS picks up any 6 tasks of T1-T7 randomly to start with. 6 is the max it processes whereas i have more than that. Can i change this setting???
2. Its not guranteed that if say Task t1 of FOR loop F1 is executed the subsequent task for Delay within tat For loop would be executed next. Typically wat happens is it starts with T1-T6 (T7 onhold) and then exec the delay for T1-T5 and passes control to T7 without going into the delay for T6.This is not the intended execution.
What i want is exec T1-t7 ..delay for the next exec and start again.
How do i do this.

Hi,
We have a problem importing the flat file data using SSIS into sql database.
For some erroneous files the package is just hanging with out any activity (Disk Reads/sec, Disk Writes/sec, Page faults/sec, Workingset Memory counters are const when the package hung). The package is giving the following messages before it is hung.
The column data for column "ServerName" overflowed the disk I/O buffer.
An error occurred while processing file "M:Tani1APS-PRXY-02APS-PRXY-02-ISALOG_20060621_FWS_001-2006062106.Log" on data row 1.
The PrimeOutput method on component "Firewall Data" (6109) returned error code 0xC0202092. The component returned a failure code when the pipeline engine called PrimeOutput(). The meaning of the failure code is defined by the component, but the error is fatal and the pipeline stopped executing.
Thread "SourceThread0" has exited with error code 0xC0047038.
Thread "WorkThread0" received a shutdown signal and is terminating. The user requested a shutdown, or an error in another thread is causing the pipeline to shutdown.
Thread "WorkThread0" has exited with error code 0xC0047039.
Even though it says has SourceThread0 has exited, it package is not terminating itself. We just want to ignore the errorneous file and move on to other files.
I tried altering DefaultBufferMaxRows in between 1000-10000, DefaultBufferSize to 1 MB €“ 20 MB which did not work out. Can one of you suggest us any resolution/work around for this issue? This is really a burning issue in our project would really appreciate any help!

Hi All
I am facing problem while processing my SSIS package
The error is:
"Invalid delimited data. Text qualifier must be followed by a column delimiter (except for the last column)."
The text qualifier is the double-quotes character “. Text fields are supposed to get a double quote at the beginning of the string and one at the end. The column delimiter is the upright bar or pipe character |.
Some of the descriptions in table column have double-quotes embedded within the text string. When SSIS encounters one of these embedded quotes, it thinks that is the end of the text string and expects to find the column delimiter character next. It doesn’t, because the " is embedded between other alphabetic characters, so it raises an error.
For example if my column value looks like Test"String"One
What old DTS doing:
DTS make the embedded " into "". The resulting text string then would look like this:
"Test ""strings"" one".
When running the same data into a database using DTS, DTS recognized automatically the "" in the string and changed it to " so in the target the string looked like this: test "string" one. No problem.
SSIS, however, does not allow and does not support doing this "doubling" of embedded " when you are using " as the text qualifier. So it exports the sample string above like this (I added the column delimiters as well):
|"test "string" one"|.
That then causes the error
Please help me out

I've got a falrly simple task I'd like to achieve in SSIS without scripting if possible.
I have a table with three columns, Cust ID, Address and Group ID
I want to update the Group ID with a counter that increments every time the Address changes.
So currently the table looks like
Cust ID Address Group ID
62 ABC
57 DEF
79 DEF
42 GHI
11 JKL
20 JKL
and I want to end up with
Cust ID Address Group ID
62 ABC 1
57 DEF 2
79 DEF 2
42 GHI 3
11 JKL 4
20 JKL 4
I have created a view over this table that counts and Groups by address. This looks like
Count Address
1 ABC
2 DEF
1 GHI
2 JKL
What I'm thinking of doing is reading the View in Address order and updating the table (joining on Address) with a counter that increments for every row of the View read.
What I'm not sure of is how to increment this counter without creating a script. One thought I had was to create a new table from the view, and add an Identity column somehow (is this feasible in SSIS?)
Any advice appreciated

Hello,
I have a DTS package that copies data from a fixed width file and inserts it into a SQL Server 2000 table. These files are generated daily, and usually contain about 200k records.
Sometimes, the format of the file between two days can differ slightly. I can't tell if the problem lies with the length of the record string, or the string terminator. The record string is supposed to begin with 'D1'. One file (as viewed in Notepad) will contain the records each in its own row, and each row will start with 'D1'. Another file will show that the first record starts with 'D1', but then the next record does not begin on a new line. Instead the next record continues at the end of the previous record. In this case, 'D1' is preceded with an unrecognized character as if it to indicate a carriage return.
Anyway, in SSIS, when I configure the row width of the fixed width file in the flat file connection manager to 386, and the beginning of all the records are all on their own row, the data processes without a problem. When the records do not all begin on their own row, the data will process fine if I change the row width to 385.
I don't have to compensate for this in DTS. Between SSIS and DTS, both flat file connections are configured with a row delimiter of LF, and no text qualifier. Why will SSIS and DTS process these files differently?
Thank you for your help!

I have an olap database "A" and SSIS package "P" which process all the dimensions and cubes in "A" olap database.
I created "A1" olap database copy of "A" and made copy of "P" SSIS package as "P1"
I opened "P1" SSIS package and updated olap connection properties "Initial Catalog = A1". A1 is my new olap database.
When I run package "P1" guess what? it processed "A" olap database's cubes and dimensions. Try it, not in production because I did it in production.

I'm currently trying to pull data from a ProvideX database and replicate it in a collection of SQL Server tables. However, I'm having a heck of a time trying to convert some strange decimals stored by the ProvideX database. As an example of the data I'm trying to retrieve, I'll see something like [. 1] or [. 1] ([]'s are to show the bounds of the field). After analyzing the data, it seems the decimal in the field represents a 1,000 placeholder. Thus [. 1] really means 1, and [. 1] really means 10. Something like .100 would be 100. 6.500 would be 6500.
As you can imagine, the spaces are causing errors when trying to pull the data, and I can't for the life of me figure out to just pull it as a string, run a script to convert it to a correct number, and then save the transformed data into SQL Server. When running the import wizard, it seems I'm being forced to pull these columns as decimals. Currently I'm trying to just pull the data out "as is" and throw it in a raw file, to be processed out of SSIS. Obviously doing it all within SSIS would be ideal, but if that can't be done, I'll do whatever it takes. I should also say I'm new to SSIS packages, but not necessarily new to SQL Server or SQL in general.
1) How can I pull these columns as strings? If I try to change the Export columns in the source query data flow step, it gives me an error saying that I can't do that.
2) If I have to pull as decimals, how can I capture the row on error, process it, and send it back to the export? So far, when I get an error, I lose all information in the row to the right of and including the error field.
I appreciate any responses, as I'm kind of going in circles at this point. If this sort of thing has been discussed here prior, I apologize...I didn't find it in any searches I did. Please just point me in the right direction if you've dealt with this sort of problem before. It seems to me that it should be an easy thing to do. I'm just not finding any tutorials on it.

What are the general guildlines for choosing these settings, like paralle vs. sequential, different error configurations? The default selection for processing multiple dimensions is paralle and use default error configuration. But the default for processing multiple partitions is sequential. I cannot find anything helpful other than the definitions from the online help. TIA.
