Open Source Mac Clustering Software

A JDBC driver proxy that adds light-weight, transparent, fault tolerant clustering capability to any underlying JDBC driver.

The iChilli mobile J2EE platform provides a J2EE compliant runtime environment for both server and mobile platforms, such as J2ME, MIDP or other CLDC based devices. For example iChilli runs on the PersonalJava enabled Sharp Zaurus and Compaq's iPAQ.

Fourfive is a powerful yet extremely easy-to-configure web reporting solution for Oracle and possibly other RDBMS.

Momoko is a framework for developing distributed, multi-user, network-aware applications. It includes facilities for storing objects in a tree structure, a shell for manipulating the object database, orthogonal persistence, scripting support, and a trans

Recall is a framework for building distributed, fault-tolerant, replicated storage servers.

Atomatrix is a multithreaded execution system of atomic matrices with a dynamic compiler and a network eviron. It is the next generation object-orientated environment. XML, MUD-OO CLI, GnucDNA support, windows and many subprojects are built-in.

Job Accounting and User and Project managment for Clustered Computing using Perl, Apache, and MySQL. Designed to be extensible, it processes logs from currently PBS, OpenPBS and Maui2. It also contains a web frontend for User and Project Managment

Chordless is a Chord and DHash implementation written in java. It implements almost everything from Chord and DHash described at http://pdos.csail.mit.edu/chord/, as well as some extra features such as transactions and remote method invocation.

Cos provides a high level interface to application developers wishing to manipulate objects stored in a corportate wide data source lightweight data entries are manipulated by services that are able to appear and dissapear across the network as needed.

DBD2 inserts database records from TCP input. It is a companion project to Syslgod2 and an application in its own right. It ships with a backgrounding client for generic use. The client sends whatever information the user puts on the command-line to the back-end daemon via TCP. Upon successful transmission, the client exits. On failure, it backs off and retries until its life-time timer expires. The back-end daemon accepts data from Syslogd2 or its own client and inserts that data (and envelope information) into one or more databases using MySql client library or dbi drivers (also on SourceForge). The client needs no configuration (all input is via command-line). It is intended for hosts to make database entries without needing database client or interface code. Syslogd2 integration allows DBD2 to act as Syslogd2's database back-end for MySql and other databases supported by the dbi drivers. Original purpose was to track Linux cluster job status but other uses exist.

JReplica is a java distributed database replication system developed during a European Research Project in the department of Informatics of University "La Sapienza" of Roma under the supervision of Prof.ssa Catarci, Prof. Santucci and Ing. Curci.

LeverPack is a small, transaction based, secure, concurrent, and efficient record repository management engine written in Java. It provides READ_COMMITTED transaction isolation level supported read/write access to user data records.

The Open Design and Integration Environment is a toolbox of C and TCL code designed to introduce people to programming in a friendly way. It is also designed to be robust enough to novices to develop useful applications.

By far the simplest and fastest petstore implementation. Available on CVS.

Ridiculously simple, Prevayler provides transparent ACID persistence and replication for plain old Java objects. It is literally several thousand times faster than using a relational database through JDBC.

Sequoia is a database clustering middleware offering load balancing and transparent failover. Databases are replicated over multiple nodes and Sequoia balances the queries between them. Sequoia supports online maintenance and recovery operations.

elasticsearch-head is a web front end for browsing and interacting with an Elastic Search cluster. elasticsearch-head is hosted and can be downloaded or forked at github. There are two ways of running and installing elasticsearch-head. Running as a plugin of ElasticSearch (this is the preferred method). And running as a standalone webapp. By default es-head will immediately attempt to connect to a cluster node at http://localhost:9200/. Enter a different node address in the connect box and click 'Connect' if required. A ClusterOverview, which shows the topology of your cluster and allows you to perform index and node level operations. A couple of search interfaces that allow you to query the cluster a retrieve results in raw json or tabular format. Several quick access tabs that show the status of the cluster. An input section that allows arbitrary call to the RESTful API to be made. This interface includes several options that can be combined to produce interesting results.

A collection of implementations of the Paxos and FastPaxos algorithms for solving consensus in a network of unreliable processors. Visit http://libpaxos.sourceforge.net/ for more informations
