Hi List, I am new to ERJGroupsSynchronizer. I want to synchronize Enterprise Objects between Application's instances. I found the following info:
http://web.archiveorange.com/archive/v/VpmAs9yFWUtMJyEvmKXQ I followed those instructions and added this to my Properties file: ### Basic setup: ######################################################################### # ERX Remote Synchronizer ######################################################################### ## To use remote EOF synchronization, you must turn on the ## ERXObjectStoreCoordinatorPool. Just setting it to 1 is enough to ## allow things to work. er.extensions.ERXObjectStoreCoordinatorPool.maxCoordinators=1 ## Enables remote synchronization (required in addition to ERXObjectStoreCoordinatorPool). er.extensions.remoteSynchronizer.enabled=true ######################################################################### # ERJGroupsSynchronizer # This synchronizer is based on the JGroups clustering framework, which # is the clustering framework used inside of JBoss (among many other # applications). You must include the ERJGroupsSynchronizer framework # in your application for this to work properly. ######################################################################### er.extensions.remoteSynchronizer=er.jgroups.ERJGroupsSynchronizer ### The above is enough to get things going. Advanced Setup: ### AFAIK this didn't make a difference on OS X last time I checked, but it matters on e.g. Linux ## (Optional) the multicast address to use (defaults to 230.0.0.1, and only necessary if you are using multicast) er.extensions.jgroupsSynchronizer.multicastAddress=230.0.0.1 ### Change this to some unused port for the group when you get "Discarded packet from..." messages in the logs ## (Optional) the multicast port to use (defaults to 9753, and only necessaryif you are using multicast) er.extensions.jgroupsSynchronizer.multicastPort=9753 ### Limit to localhost when deploying all instances on the same server ## (Optional) The local bind address defines the network interface that will be used ## to transmit and receive multicast messages. If not set, multicast synchronizer ## will use WOApplication.application().hostAddress(). If you want to run outside ## of a WOApplication, you should set this value explicitly. er.extensions.jgroupsSynchronizer.localBindAddress=127.0.0.1 ### Set this if you have differently named apps that use the same Model&DB (e.g. MyFrontend.woa and MyBackend.woa) ## (Optional) the JGroups group name to use (defaults to WOApplication.application.name) #er.extensions.jgroupsSynchronizer.groupName=SomeGroupName ## (Optional) A comma separated list of entities to multicast synchronize. The ## default is to not set this, which translates into "include all entities". #er.extensions.remoteSynchronizer.includeEntities= ## (Optional) A comma separated list of entities to NOT multicast synchronize. The ## default is to not set this, which translates into "exclude no entities". #er.extensions.remoteSynchronizer.excludeEntities= I am not sure what multicast means and also I don't know if I should create some class to catch the changes of the enterprise objects. I just configured my Properties and deployed a test application but my tests didn't work. ¿Am I missing something? ¿Is there a tutorial of how to use ERJGroupsSynchronizer? Thanks in advance. Miguel Torres.
