JDG-playground

A small project to learn and explore Jboss Data Grid (Infinispan)

Build instructions

To build the code you just need Maven and the JDG repositories installed somewhere (for a simple setup, just download the repositories and install them locally on your disk). You won't need to install the JDG server, as this example is engineered to run in Library mode.

Install the Maven repositories

Installing JDG 6.2 maven repository, which depends by the EAP 6.1.1 Maven repository, is the first step.

You'll find detailed instructions on how to install the Maven repositories in the JDG 6.2 [Getting Started Guide] (https://access.redhat.com/site/documentation/en-US/Red_Hat_JBoss_Data_Grid/6.2/html-single/Getting_Started_Guide/index.html#chap-Install_and_Use_the_Maven_Repositories)

For your reference, you will find an example settings.xml to copy in your .m2 directory in the example-maven-settings directory.

This Maven settings.xml assumes you have unzipped the repositories in the following locations, so edit it accordingly:

• /opt/jboss-datagrid-6.2.0-maven-repository/
• /opt/jboss-eap-6.1.1.GA-maven-repository

Build the code

After installing the repositories, you just have to clone the code and run some nodes. For example to launch four nodes on a single machine (or four different machines) just run these commands using different terminals:

mvn -DskipTests -P node1 clean install exec:java

mvn -DskipTests -P node2 clean install exec:java

mvn -DskipTests -P node3 clean install exec:java

mvn -DskipTests -P node4 clean install exec:java

Usage

Every node will have its own command line interface "attached", which you can use to play with your Data Grid. Type 'help' on the command line to show a list of commands:

get id
     Get an object from the grid.

put id value
     Put an object (id, value) in the grid.

modify id value
     Modify an id object with value.

locate id
     Locate an object in the grid.

loadtest
     Load example values in the grid

local
     List all local valuesFromKeys.

primary
     List all local valuesFromKeys for which this node is primary.

clear
     Clear all valuesFromKeys.

info
     Information on cache.

rotate n
     Apply a rotate n on String values with a Distributed Executor

routing
     Print routing table.

help
     List of commands.

exit|quit|q|x
     Exit the shell.
