Error Registering Plugin
Nov 13, 2007
Good evening everyone,
I'm following the steps of the tutorial on how to construct a managed data mining plugin in C#.
Once created the Metadata, Algorithm and Navigator classes I tried to register it on Analisys Service by running the XMLA template written on the tutorial but I got the following error:
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
The GUID in the XMLA is correct as so the service name. The SQL Server engine runs fine.
I noticed that when I run this XMLA, the file msmdsrv.ini is modified, so in DataMining/Algorithms session a new entry is correctly created, enabled and the GUID is also set correct.
I also tried to ignore the XMLA setting up msmdsrv.ini manually but it also didn't work.
The build process is fine, both DMPluginWrapper and the Shell are registered by gacutil and I restarted (also try to stop and start) the server.
Any ideas will be very appreciated.
Thanks,
-Renan

hello,everyone,I also met a problem.
I stoped the SQL Server Analysis Services first, and registered the GAC successfully,
then modified the msmdsrv.ini manually.In fact,I found the format of my msmdsrv.ini is diffirent from the one mentioned in the tutorial,it just like below:
<DataMining>
...
<Algorithms>
.
.
.
<MyCompany_Managed_Plugin_Algorithm>
<Enabled>1</Enabled>
</MyCompany_Managed_Plugin_Algorithm>
.
</Algorithms>
<Services>
...
<MyCompany_Managed_Plugin_Algorithm>
<ProgID>44503EAB-570E-4b25-A9F4-043949A7D78E</ProgID>
</MyCompany_Managed_Plugin_Algorithm>
...
</Services>
when i restarted the the AS,
some error information displayed in event viewer,
" can't load MyCompany_Mamaged_Plugin_Algorithm data mining Algorithm provider(ProgID,
can't create Algorithm Provider program for MyCompany_Managed_Plugin_Algorithm,
ProgID does not exist in the server configuration file"
I am confused by it and have not any idea to solve it.
some one can give tips?
thanks.

Good afternoon,
I'm doing a custom clustering plugin for text to pre-process ("clean" the texts), calculate weights, estimate the number of clusters (using the PBM index) and finally, do the actual clustering.
So... I've made each of these modules on C++ and I'm putting them all togheter on the plugin.
My database (MDB file) has only one table, with only two fields within: a key (auto-incremental) and a small text. What I intend to do is to get the text in each test case, store them togheter somewhere and call my classes to cluster these texts.
I'm trying to log the texts in a file (just a test) on the ProcessCase method, in the CaseProcessor class. I've did it with no problems with numerical data.
But when I load the MDB file on the Mining Structures Wizard, it says the content type of the field holding the texts is "Continous" and the data type is "Text". Actually, when I saw it I didn't really mind.
But when I run the mining model it gives me the following error: "Error 1 Error (Data mining): The data type of the Table1.Texto mining structure column must be numeric since it has a continuous content type (Content is set to Continuous or Key Time or Key Sequence). 0 0 "
So... How do I change this content type ? (the content type combobox on the Mining Structures Wizard couldn't the changed)
Can anyone help me on this, please ?
Thanks a lot.

Good morning,
Well... As I said in other topics, I'm doing a clustering plugin for text mining. I'm facing many problems and, with your help, solving them one by one.
First of all, thanks a lot again.
Well... I've made a clustering function that is actually working very well. But I'm exporting its results to a log file I use as an algorithm trace for debugging.
My clustering method returns a vector containing information of what cluster each register belongs. For instance:
vector[0] = 1 -> The register of index 0 belongs to cluster 1.
vector[1] = 9 -> The register of index 1 belongs to cluster 9.
vector[2] = 2 -> The register of index 2 belongs to cluster 2.
...
And so on.
But... I know that none of the Navigation methods receives a structure like this one discribed above. I only use it to log the results to debug the algorithm.
But how to pass this information (what register (or test case) belongs to what cluster) to the Navigation ?
Thanks a lot again, and any help will be very appreciated.

TITLE: New Server Registration
------------------------------
Testing the registered server failed. Verify the server name, login credentials, and database, and then click Test again.
------------------------------
ADDITIONAL INFORMATION:
An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) (Microsoft SQL Server, Error: 53)
When I try to regiter a sql server, I take this error message. I am using Sql Server 2005. What is the problem,can you help me?

Help.
When I try to CREATE/Register a third party assembly (dtsearchNetApi2) within SQL server I am getting an error (see below). I have the source code for dtsearchNetApi2 but it is in C++ and I would like to avoid having to extend/modify it if that is avoidable. I have written a 'wrapper' class in C# but sine it references dtsearchNetApi2.dll I can't register that dll either.
CREATE ASSEMBLY DBSEARCHNETAPI
FROM 'C:TempdtsearchNetApi2.dll'
WITH PERMISSION_SET = UNSAFE
Msg 6218, Level 16, State 3, Line 2
CREATE ASSEMBLY for assembly 'dtSearchNetApi2' failed because assembly 'dtSearchNetApi2' failed verification. Check if the referenced assemblies are up-to-date and trusted (for external_access or unsafe) to execute in the database. CLR Verifier error messages if any will follow this message
dtsearchNetApi2 has references to unmanaged code. The dtSearchNetApi2.dll is a .NET 2.0 wrapper around C++ objects exported in dten600.dll. It is implemented in MSVC++ with Managed Extensions is implemented in C++/CLI 2.0.

hi, Derek Comingore
My self Jitendra Nayi....
I am trying to generate a SQL CLR stored procedure and i have done it too. Now the next step is to convert that *.dll file in to assembly. I am getting erro that. My server Database is on the LAN, not on my PC.
Here is the code which i have tried to register an assembly...
/*
CREATE ASSEMBLY MyAssembly FROM 'C:Documents and SettingsAdministrator.ORC80My DocumentsVisual Studio 2005ProjectsMyDB1MyDB1inDebugMyDB1.dll'
WITH PERMISSION_SET=SAFE

*/
and here is the error that i am getting...

Good morning everybody,
I'm here once again asking for help. Here's my problem:
I have a table that I use in my text mining clustering third-party algorithm. The table is as follows:
ID: primary key (int)
ID_DOC: an ID I use to know from what document a term came from (int)
ID_TERMO: the term ID (int)
TERMO: the term itself (varchar(max))
FREQ: the term frequency, usually TFxIDF (real)
Alright... I need the term itself to do some visualization. What I want to do is to get each case's term and store'em on a vector<char*>. So I did some changes on the ProcessCase method. In this method the data (each variable of the case) can be accessed rolling over the case using a DM_STATE_VALUE* as follows:
DM_STATE_VALUE* xpto = (DM_STATE_VALUE*) rgValue;
for(unsigned int i=0;i<_cAttribute;i++) { // _cAttribute is the number of variables
double aux = xpto.r8;
//Do some calculation using aux
}
Alright... It works quite well when I only have real and int data types on the database. But how the get the term collumn (varchar(max)) ?
How to modify the DM_STATE_VALUE union to accept strings as well ?
Any clues are wellcome.
Thanks a lot once more,
-Renan

Hi,
I want to create a Data Mining Plugin-Algorithmn that uses existing mining models in the current DB. Is there a way to get a AdomdConnection from within an (Managed) Plugin-Algorithmn? This Connection should point to the current SSAS-Database.

Hi,
I spent the last days programming a managed datamining plugin-algorithmn for SSAS 2005 and have troubles with the Prediction-Method.
Die Prediction-Methode of the "Shell-Algorithm" leads to an error-message on execution of the prediction-query (Internal Error: Unexprected Error ... dmxpredict.cpp Row 205 ...).
Can anyone provide me with a very simple implementation of this Method which just says that for every output-attribute the first (discrete) state should be predicted with a probability of, let's say, 90 % ?

as we know we get clustering algorithm with managed plugin algorithm API
does anyone have developed any other plugin algorithm as i want to check what are the things that needs to be modified. i am not data mining algorithm developer but i just want to check where we have to make changes. i would be better if i get source code for algorithm other than clustering
ANOTHER PLUGIN ALGORITHM REQURIED??

Good afternoon,
I've developed a clustering plugin for SQL Server 2005 but now I want to port the .dll so my algorithm can run on another machine. Both machines have SQL Server 2005 installed, but different versions of Windows.
What are the steps I need to follow to port the plugin ?
Any help will be very appreciated.

We have written a test CRL stored procedure to test replacing one of our complex stored procedures but can€™t get it deployed to our SQL server that hosts a mirrored configuration of our production database (very locked down). It works fine on our development instances (not very locked down). It only references the default assemblies that were added when we created the project. All it does is use Context Connection=true to get data, loops though some records and returns the data using SQLContext. CLR is enabled on SQL server, the assembly is strongly signed, and we tried deploy using the binary string with the SAFE setting.
CREATE ASSEMBLY for assembly 'SQLCLRTest2' failed because assembly 'SQLCLRTest2' failed verification. Check if the referenced assemblies are up-to-date and trusted (for external_access or unsafe) to execute in the database. CLR Verifier error messages if any will follow this message
[ : SQLCLRTest2.StoredProcedures::GetLift][mdToken=0x600001e] Type load failed.

Function ... Row 1 ... Column 43 ... cannot be used in this context.
(I've translated the key facts of this error message from german)
What did I do wrong?

Hi,
After I've written my first Plugin-Algorithmn, I have some general questions about the Managed Plugin-Algorithmn wrapper.
What does the Property "support" express in view of predictions? Is it the overall number of cases the found rule works for?
What's the difference between AdjustedProbability and Probability ?
There is a probability for a specific StateStatistic and one for the whole AttributeStatistic.
What does the latter one express? Perhaps the overall probability that the discovered rules will lead to correct results for this attribute ? Let's say I have two rules for an attribute. Rule A has a probability of 0.5 and Rule B has a probability of 0.66. What would be AdjustedProbability.Probability in the case? The mean of 0.5 and 0.66 ?
Best whishes,
Manfred

We have a large number of SPs in our databases and decided it was time to get some source control. I have VSTS team explorer installed and working in visual studio, but I cannot get the plugin for SSMS to work - it just says none in the current source control plug-in dialogue box - nothing when I drop it down either.
Any ideas what I am doing wrong?

Does anyone know what SQL Server uses to identify other servers which contain SQL Server, when you attempt to register a new server through enterprise mgr? For instance when you go through the new sql server registration wizard, the second screen allows you to choose what server you would like to register, and it shows you the available servers on the lan that contain sql server 6.5 or 7.0. What is enterprise mgr using to locate the other servers containing SQL Server? Thanks in advance.

Can anyone give me advice on how to register 6.5 servers using SQL 7.0. Every time I try and register a 6.5 servers it fails. I get an error stating that "I must upgraded the 6.5 server or later to be administered by this version of SQL-DMO". I can't upgrade the server to 7.0 because the COTS product that we are using as the front end relies on 6.5. Is there any way to do this? Or do I have to install 6.5 on my workstation as a separate application than 7.0? Someone please help?

I just created a new db on a programmer's machine. Now I cannot register his sql server on my sql server. It doesn't like 'sa'. I can connect as 'administrator' but then I cannot do anything. Seems like the logins are messed up. I am not able to execute any stored procedures as administrator.
Any ideas besides reloading sql?
Thanks.

When using MSDE or SQL7 as the back-end to Access2000 projects (adp),
the examples often have an .mdf file to match such as say NorthwindCS.mdf
The instructions are:
1. set this file aside,
2. create a database with this name then
3. stop SQLServer,
4. copy own file to msql7data...
5 use it....
although this soemtimes works, i mostly get a "suspect" database
I was hoping to fix this with DBCC REPAIR, but support for this command seems
to have disappeared

Hi,
I mistakenly registered a SQL 6.5 server in SQL 7.0. I would like to remove the registration entry, since I often will click it by acident, and it will fire up the SQL 6.5 EM session. However, when I right click on the server and try to select the "Delete SQLServer Registration" from the menu, that option is greyed out. Is there any way I can remove this SQLServer somehow?
Thanks,
Joe

Hi! Just started playing, but when I try to register an active (on the network) 6.5 server in the 7.0 EM I get the message that I must upgrade the 6.5 server...I know in 6.5 I could access 6.0 servers after runnning a script on the 6.0 server, but so far I don`t see anything like this for 7.0. Will I end up having to run 2 versions of EM on a machine (if possible) to access my 6.5/7.0 servers? (I know I won`t be able to do anything fancy, but it is nice (under my 6.5 EM) to be able to manage server activity/db`s from one machine, regardless of them being 6.0 or 6.5!

Hi,
I have recently installed SQL Server 2000, And trying to register a remote SQL 7 server, through enterprise manager which fails with the following error message: Timeout expired
I am able to connect to the same server using Query Analyzer.
I was able to register this server from the same machine, prior to the installation of SQL 2000. Also, I am still able to connect to other SQL 7 servers, with SQL 2000 enterprise manager.
Any Ideas?

Over the weekend we changed ISPs on our SQL Server 2000 machine. The only configuration change was the IP address. I'm able to register the server from client machines using EM which are on the same network, but I can't register it from home. I've verified the IP address, username/password etc and the connection just fails with the message 'Sql Server does not exist or access is denied.' Could this be a port issue? Any ideas? Thanks.

I need help with a problem that is driving me nuts and should be so easy that it is mindless. The problem is with registering SQL servers in Enterprise Manager.
The network is a routed environment with many subnets. TCP/IP addresses are assigned by DHCP and name resolution is done via WINS. The SQL clients are set to use Named Pipes as the Net-Library. The servers are using standard security. I have the correct sa password. Then I try to register a SQL server. It returns a message that it is unavailable.
The SQL box is visible in Network Neighborhood; is able to be pinged both via machine name and IP address; the msssqlserver service is running on the box. I can register the box using standard security and the same credentials in EM right on the server. Why can't I register it from a client?
Thanks in advance,
Ed

The organization I work for will be converting to SQL Server 2005 in the near future so I downloaded the free 90 day trial to familiarize myself with the software. I've installed the software and my plan now is to go through the Tutorials. I need to access AdventureWorks sample database. AdventureWorks did not download upon initial setup so I've downloaded/installed it into what appears to be the correct folder: c:ProgramFilesMicrosoft SQL Server90ToolsSamples. I cannot, however, seem to locate it within SQL Management Studio. As advised by the tutorial I've tried setting up a New Server Registration but I can't seem to locate AdventureWorksDB when I'm browsing for it under the Connect to Database:' option under the "Connection Properties" tab of New Server Registration.
I am familiar with database development as it relates to MS Access but I realize this is a whole new ball of wax. Any advise would be appreciated as it relates to this problem but also any information, i.e., very basic books on learning SQL Server would also be appreciated.

I'm stucked in a problem and I thought if you would be so kind as to helping me to resolve it.
I'm implementing a clustering algorithm plugin for text mining. I've already read the tutorials and sample codes provided by the MSDN Library.
Well... My problem is: I can't go through the data when the Predict method is called. I've read that this method implements the "core" of the custom algorithms. Here is a small snippet of my code for you to understand my doubt:
STDMETHODIMP ALGORITHM::Predict(/* [in] */ IDMContextServices* in_pContext,/* [in] */ DM_PREDICTION_FLAGS in_Flags,/* [in] */ IDMAttributeGroup* in_pPredAttGroup,/* [in] */ DM_CaseID in_CaseID, /* [in] */ ULONG in_ulCaseValues,/* [in] */ DM_ATTRIBUTE_VALUE* in_rgValues,/* [in] */ ULONG in_ulMaxPredictions,/* [in] */ ULONG in_ulMaxStates, /* [out] */ DM_ATTRIBUTE_STAT** io_prgPredictions,/* [out] */ ULONG* out_pulPredictions) {
for(UINT i=0;i<in_ulCaseValues;i++) {
DM_ATTRIBUTE_VALUE& dmattributevalue = in_rgValues;
ULONG iAttribute = dmattributevalue.Attribute;
if (iAttribute == DM_UNSPECIFIED)
continue;
double dblValue = ::DblContinuous(dmattributevalue.Value);
char buffer[129];
sprintf(buffer,"%f ",dblValue);
RENAN_Log::log(buffer);
}
return S_OK;
}
As you can see, I'm going through in_rgValues to get its values, but i'm only obtaining the first register of the table on the database. I need to roll over a kind of resultset so I could access all the registers I need. Is there any way to do so ?
I expected Predict() received a matrix containing all my data, but the only thing I noticed that could represent the data is that in_rgValues vector. So I can go through this vector, but it holds only the first register of the table in the database (that's what's being saved on my log). I need all of the registers in order to pre-process the data and implement my clustering algorithm.
Well... That's it... I would be very pleased if you could help me.
