Is there a way to dynamically reload the Terracotta configuration file without restarting Terracotta and losing Session replication for every web app? More Info: I'm in charge of about 30 unruly, legacy Java Web Applications. My goal is to setup our servers so that I can quickly redirect all traffic from one Tomcat instance to anothe...
What do you think is the maximum database size ever stored on sql server cluster? ...
Hi I have used SMO API.in that i have used SmoApplication.EnumAvailableServers(FALSE) and from that i have filtered local instances i have used this approch insted of true to make this as convinent for remote sqldiscovery also.using that api created a dll and use that dll in c++. Now this is working in all combinations but some times i...
I'd like to use correlation clustering and I figure R is a good place to start. I can present the data to R as a set of large, sparse vectors or as a table with a pre-computed dissimilarity matrix. My question is are there existing R functions to turn this into a hierarchical cluster with agnes that uses correlation clustering? Will I ...
Is there anything special I need to do when installing the oracle 10 client software on a windows cluster? The client is needed to provide access to an oracle db from a sql server as a linked server. Should it be installed to a shared disk, or is it ok to install on local storage? ...
Thanks to this answer I managed to come up with a temporary solution to my problem. However, with a list of 6000 points that grows everyday it's becoming slower and slower. I can't use a third party service* therefore I need to come up with my own solution. Here are my requirements: Clustering of the coordinates need to work with ...
Task: to cluster a large pool of short DNA fragments in classes that share common sub-sequence-patterns and find the consensus sequence of each class. Pool: ca. 300 sequence fragments 8 - 20 letters per fragment 4 possible letters: a,g,t,c each fragment is structured in three regions: 5 generic letters 8 or more positions of g's...
I know how to write a similarity function for data points in euclidean space (by taking the negative min sqaured error.) Now if I want to check my clustering algorithms on images how can I write a similarity function for data points in images? Do I base it on their RGB values or what? and how? ...
Hello Does anyone know of training available on the web which highlights data synapse in a Java enviroment please?? ...
Does anyone know how a computer cluster can be used for everyday applications, like for example video games? I would like to build a computer cluster that can run applications over the cluster that were not specifically designed for computer clusters and still see the performance increase. One use would be for video games, but I would ...
I'm doing some tests clustering a big number of very large sparse vectors representing term-frequency-inverse-document-frequency of various hypertextual documents. What algorithm would you suggest for clustering this data, taking into account the proportions of the data set? The dimension of the vectors would be > 3·105 and the number of...
I am looking for Python implementation of k-means algorithm with examples to cluster and cache my database of coordinates. ...
I want parallelize a program. It's not that difficult with threads working on one big data-structure in shared memory. But I want to be able to use distribute it over cluster and I have to choose a technology to do that. MPI is one idea. The question is what overhead will have MPI (or other technology) if I skip implementation of speci...
I'm writing a small web service(like a content server) to search and serve content. Basically it has 2 parts - one dynamic part performing client authentication and providing search functionality over the content. The second part involves serving static content to the authenticated client. What can be a good architecture for the above s...
While running performance testing I've noticed that all the requests from any given IP address seem to all be going to the one cluster member. I've got about 7 concurrent users plugging away, and one server's got log activity while the other is sitting idle. Needless to say this is going to mess up my testing results unless I can find a...
I have a webapp deployed to three servers running Apache, Tomcat and a load balancer in front of them. Now I am thinking of clustering them. Here are the options usual options and my constraints that I am aware of: Serialization based Session clustering: In my case, the application uses a lot of objects in session. So I would prefer n...
We have two tables, ActivityForm and Field which are given a many-to-many relationship via the ActivityFormField table. The ActivityFormFieldValidator table will have a many-to-one relationship with the ActivityFormField table, so we are giving the ActivityFormField table an identity column ("ActivityFormFieldId"). The ActivityFormFiel...
Would it be possible to make a python cluster, by writing a telnet server, then telnet-ing the commands and output back-and-forth? Has anyone got a better idea for a python compute cluster? PS. Preferably for python 3.x, if anyone knows how. ...
Let's say that you have a list of 10,000 email addresses, and you'd like to find what some of the closest "neighbors" in this list are - defined as email addresses that are suspiciously close to other email addresses in your list. I'm aware of how to calculate the Levenshtein distance between two strings (thanks to this question), which...
I have a setup of 2 WLS managed servers configured as part of a WLS cluster. 1) The requirement is to send requests to another system and receive responses using JMS as interface. 2) The request could originate from either of the Managed Servers. So the corresponding response should reach the managed server which originated the request...
