gridgain

What is the advised approach to ensuring a particular process is running exactly once within the grid? Usecase would be subscription of a single multiplexed stream from a remote source in order to update data across the grid. We need to elect the node to subscribe and elect a new node to subscribe when that node fails. Is there any pre-built pattern for this in gridgain or is it solved by a combination of listening to grid lifecycle events and a distributed CAS operation? Another usecase would be a singleton job that must run forever, migrating to a new node on failure. Thanks. Starting with

Can anyone help me in guiding to use grid gain, The documentation on website is not enough and confusing. We have to run thousands of simulations in the LAN. can anyone help me in running compute grid on multiple hosts in a LAN. I am able to run compute example on multiple nodes on same host, but not on multiple nodes on multiple hosts. Kindly help. Compute examples are configured to work with local host settings. All you have to do is update IP addresses in examples/config/example-compute.xml file to the IP addresses in your environment. You only need to provide at least 1 IP address of the

I'm trying to set up a Gridgain cluster with 2 servers. Load data from a .csv file (1 million to 50 million data) to the Gridgain using GridDataLoader . Find the min, max, average, etc. from the data loaded, When running as a standalone application in eclipse I'm getting correct output. But while making a cluster (2 nodes in the 2 servers + 1 node inside my eclipse environment), I'm getting java.lang.OutOfMemoryError: GC overhead limit exceeded error. The configuration file I'm using is http://pastebin.com/LUa7gxbe Changing eclipse.ini's Xmx property might solve the problem. Change it to

I am trying to set Apache Ignite as the second level Hibernate cache provider in my project but i am getting a strange exception.

This is the ability to run your application on a cluster of servers with the intent to distribute the load and also provide additional redundancy. I've seen a presentation for GridGain and I was very impressed with it. Know of any others? There are several: Terracotta ( open source, based on Mozilla Public License ); Oracle Coherence (formerly Tangosol Coherence; commercial; based on JSR 107 , which was never adopted officially); GigaSpaces (commercial; based on JavaSpaces API , part of Jini ); GridGain , which you mentioned (open source: LGPL ); memcached with a Java client library (open
