8.3. Configure Replication Mode (Remote Client-Server Mode)


Replication mode is a clustered cache mode in Red Hat JBoss Data Grid. Replication mode can be added to any cache container using the following procedure.

Procedure 8.1. The replicated-cache Element

The replicated-cache element configures settings for the distributed cache using the following parameters:
  1. Add the Cache Name

    The name parameter provides a unique identifier for the cache.
    <cache-container name="local" 
    		 default-cache="default" 
    		 statistics="true">
    	<replicated-cache name="default">
    
  2. Set the Clustered Cache Start Mode

    The mode parameter sets the clustered cache mode. Valid values are SYNC (synchronous) and ASYNC (asynchronous).
    <cache-container name="local" 
    		 default-cache="default" 
    		 statistics="true">
    	<replicated-cache name="default" 
    			  mode="SYNC">
    
  3. Set the Cache Start Mode

    The start parameter specifies whether the cache starts when the server starts up or when it is requested or deployed.
    <cache-container name="local" 
    		 default-cache="default" 
    		 statistics="true">
    	<replicated-cache name="default" 
    				mode="SYNC"
    				start="EAGER">
    
  4. Per-cache Statistics

    If statistics are enabled at the container level, per-cache statistics can be selectively disabled for caches that do not require monitoring by setting the statistics attribute to false.
    <cache-container name="local" 
    		 default-cache="default" 
    		 statistics="true">
    	<replicated-cache name="default" 
    				mode="SYNC"
    				start="EAGER"
    				statistics="true">
          		...
    	</replicated-cache>
    </cache-container>
    
  5. Set Up Transactions

    The transaction element sets up the transaction mode for the replicated cache.
    <cache-container name="local" 
    		 default-cache="default" 
    		 statistics="true">
    	<replicated-cache name="default" 
    				mode="SYNC"
    				start="EAGER"
    				statistics="true">
    		<transaction mode="NONE" />
    	</replicated-cache>
    </cache-container>
    

Important

JGroups must be appropriately configured for clustered mode before attempting to load this configuration.
