Information Of Sequence Clustering

Aug 14, 2007

I��m a college student currently studying 10th semester in the Universidad de los Andes, Colombia and I��m working on a data mining project. I need to use the cluster sequence approach; therefore I need to completely understand how it works. In order to understand it, I need to know which inputs it uses, how the algorithm works and which type of outputs does the approach throw. Do you have any idea where I can find this type of information? and examples?

Any help would be appreciated.

Thank-you for your time.

Sequence Clustering Capabilities

Nov 10, 2006

Hi!

I've read a lot of informoation about the Microsoft Sequence
Clustering algorithm, but the more i read more confused i get. Here's
my doubt:

Can it discover sequences of "tokes" and then group them? Or only compare sequences in order to group them?

Thanks in advance

Sequence Clustering Error

Oct 10, 2006

I get this message when I deploy my sequence clustering model:

Error 1 Error (Data mining): Duplicate Key Sequence values in an input case for SeqCluster. Ambiguous case(s) may lead to unreliable results. Disambiguate the data (recommended) or increase ErrorLog KeyErrorLimit server parameter. 0 0

I don't have any duplicate keys in my case table. I'm using a date for my key sequence column in my nested table. Is that the problem?

Sequence Clustering And Association Rules

Jul 13, 2006

Hi

I read the paper of sequence clustering. It seems that the major application of the algorithm is for the web site. I was just thinking that can I apply this algorithm on the purchase sequences of credit card data?

If so,please also tell me the difference between sequence clustering and association rules on credit card data application. Although I realize that sequence clustering is a fully probabilistic model and it has the capability of prediction, association rules also give the probabilities of purchasing the other products.

Thanks in advance.

Hi, all experts here,

Thank you very much for your kind attention.

I have a question on sequence clustering algorithm. As generally it is used for sequence analysis especially for web path visiting analysis. Besides that, what else scenarios could we apply this algorithm as well?

Thanks a lot in advance and I am looking forward to hearing from you shortly.

With best regards,

Sequence Clustering Model Processing Fails Due To Sort Order

Dec 18, 2007

I am using Sequence Clustering algorithm. (I've built several models with Clustering algorithm and Decision Trees for this client, which work fine.).

Background: Sequence data must be stored in a nested table, which can have only 1 non-key attribute.
I specify a mining model structure with the nested table key as the datetime, and the nested table discrete prediction column as [sort name] . this builds the model fine.

When I try to process this data mining model, I get Process failed: "Errors in the OLAP storage engine: The sort order specified for distinct count records is incorrect".

Iit may be that OLAP distinct count requests numerical data type, but not from the examples I've seen. Tried this anyway �� doesn��t work on numeric either �� same problem.
Any Suggestions?

Transfer A Database From Non-clustering To Clustering Env.

Nov 13, 2007

We have 2 env. : Testing and Production, both are running Windows 2003 Enterprise Server with SQL Server 2005. The difference is Testing is NOT running Windows cluster but Production do so, what is the best way to transfer a database from testing to production?

We have another systems that both testing and production are running on NON-cluster and we use backup/restore to transfer the database, can it apply in this case.

And I found that there are a tools called DTC, which can transfer all DB objects from one DB to another, is it a best way to transfer between non-cluster and cluster env.?

SecurityException Class SQLServerDatabaseMetaData's Signer Information Does Not Match Signer Information Of Other

May 23, 2007

Hello,

I have some troubles with IBM WebSphere Application Server using MS SQL Server 2005 JDBC Driver. I always get the error e.g.
java.lang.SecurityException: class "com.microsoft.sqlserver.jdbc.SQLServerDatabaseMetaData"'s signer information does not match signer information of other classes in the same package

I found this Feedback but it seems to be closed.

A temporary solution for me was to delete the meta-inf directory of the JAR-File, but that can't be the solution.

Can anyone help me with this problem?

SQL Clustering-NT Vs W2K?

Nov 20, 2001

We are in the process of consolidating all our SQL6.5 and SQL7 databases to a single SQL 7 server - once completed we want to setup a 2 node SQL7/2000 cluster on either NT4 Enterprise or W2k Advanced Server. I would therefore appreciate any advice in choosing between the two platforms based on cost, ease of setup & configuration and ongoing reliabilty & uptime etc - we currently have no NT4 Enterprise Servers so would have to purchase these licenses anyway. Correct me if I am wrong but I also understand that setting up a cluster on NT4 Enterprise is considerabely more complicated and time consuming than on W2K Advanced Server? Any advice would be greatly appreciated..

regards

Clustering

Feb 14, 2005

I have a question relating more to documentation and support. I'm trying to find documentation on clustering.

I remember quite some time ago I found a white paper that literally walked you through every step involved in setting up a SQL Server failover cluster. I had also found a white paper that walked you through setting up an Active/Active cluster.

I've been going through Microsoft's site, but all I've found are little bits and pieces.

If anyone can point me in the right direction, or even provide a link, etc. as to where to find some good solid documentation, that would be awesome.

Thanks!!

SQL N + 1 Clustering

Mar 4, 2008

We currently have a cluster configuration that is running as failover with one shared SAN storage solution. Two servers running Windows Server 2003 Enterprise and SQL 2005 Enterprise. We have two nodes right now running in failover and we will be purchasing a third.

Everything is working now, but we would like to move to an N+1 configuration with two active nodes hosting a separate SQL instance each with one failover node. I've seen N+1 mentioned on about a dozen Microsoft websites, but I cant find any documentation on how to setup or configure this clustering method. Has anyone ever set up a configuration like this or seen any documentation on how to do it? Is it possible to run failover with three nodes, two of them being active?

Any insight would be greatly appreciated.

Clustering Questions

Jul 24, 2000

Does anyone know the answers to either of these, given that we are talking about an active/passive cluster using MSCS, and we use Groupwise for mail (don't ask!)?

1) How do I configure Agent Mail on the cluster under this setup?

2) How do I set up linked servers from this setup to other (non-clustered) SQL servers - I can set up the cluster virtual server as a linked server from the others OK, but the other way around doesn't work - perhaps not surprisingly, but is there a way around it?

Thanks

I need some documentation on how to trouble shoot clustering SQL7EE. I have setup the cluster and looks like it is working but I missed somthing. When I test a failover by pulling the Network cable to the main network not the heartbeat network both boxes lock up. I can failover by powering down one box and using the MSCluster Admin. I am using NT40 6a on Dell PowerEdge 2400 and PowerValut 211s

Clustering With NT/SQL Server

May 1, 2000

Those of you who are using MS Clustering, what are some advantages vs. a third party product such as "Double-Take" ? If you have used "Doube-Take" I would be extremely interested in your thought of the product.

Is it relatively easy to setup and configure with and environment
that's using all the standard products of BACKOFFICE (SQL Server 7.0 Standard Edition, NT 4.0 Standard Edition etc...)

Any hints, tips, etc... would be also GREATLY appreciated.

SQL Server Clustering

Jan 28, 2000

I have a question about database clustering. I am loking for the solution for the databse scalability, performance and zero downtime especially for MS SQL Server. As my understanding (correct if I am wrong), only Oracle provides 2 DB Servers (parallel server) or NT clustering for two sql servers. The drawback for these solution is only one server is working and another one is standing by. It is not efficent (which only 50%). Is any way that I could built the DB server farm which every DB server is working, if one failed, throw it away, rest of them still working; if I need more power, just add another db server box.How to solve the data sync problem ? Replication is not good for more than 4 or 5 db servers in the farm. Disk mirror is not good since if the server is down, there is no way to access the disks. DO you have any good idea ?

Clustering SQL Questions

Sep 7, 1999

2 Clustering Questions for you.

1. If I cluster 2 SQL servers in an active/active configuration and want to have a seperate disk array to house the data, do I need to have 2 disk arrays, one per server, or can I have one disk array?

2. When installing an application's database on the first(primary) sql server in an active/active configuration, do I need to install it on the second(secondary) server also? The second server will pick up the processes if the first fails.
