Configure ehcache

The ehcache is an open source Java™ distributed cache for caching, Java EE, and light-weight containers. Every node in the cluster can use the same plan_ehcache.xml file or you can set a different plan_ehcache.xml file for each node. For installations in a cluster, edit the plan_ehcache.xml file so you do not have restart the computer if you make changes to templates or offer folders.

Important: If your installation is upgraded from a previous version, some or all of the sections in the plan_ehcache.xml file might not be present. In that case, add and edit the file as shown in the sections that follow.

Use one of the following procedures to configure the ehcache file.

Configuring ehcache with Remote Method Invocation (RMI)

Marketing Operations systems that have the following topography typically use RMI:

Server with load balancing, two more servers

Go to the <IBM_EMM_Home>\<MarketingOperations_Home>\conf directory and open the plan_ehcache.xml file in a text editor. Then, make the following edits:

  • Uncomment the following section of the file.

    You must customize the items that are shown in bold (machineA, machineB, and port) to reflect your environment. Provide a pipe-separated list of all machines in the cluster, by using fully qualified host names.

    <!--
<cacheManagerPeerProviderFactory 
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
properties="peerDiscovery=manual,
rmiUrls=//<ServerA>:40000/planApplicationCache|//<ServerB>:
40000/planApplicationCache"/>

<cacheManagerPeerListenerFactory
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" 
properties="port=40000, socketTimeoutMillis=20000"/>
-->
  • Uncomment the following section of the file.
    <!--
<cacheEventListenerFactory
class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
properties="replicateAsynchronously=true, replicatePuts=true,
replicateUpdates=true, replicateUpdatesViaCopy=true,
replicateRemovals=true"/>
<cacheEventListenerFactory
class="com.unicacorp.uap.common.cache.PlanCacheEventListenerFactory
"net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory" />
-->
  • If the following lines are present in the file, remove them. 
    <bootstrapCacheLoaderFactory class=net.sf.ehcache.distribution.
RMIBootstrapCacheLoaderFactory"/>

Configuring ehcache with multicast

Marketing Operations systems that have the following topography typically use multicast:

Server with load balancing, one more server

Go to the <IBM_EMM_Home>\<MarketingOperations_Home>\conf directory and open the plan_ehcache.xml file in a text editor. Then, make the following edits:

  • Uncomment the following section of the file.

    You must customize the items that are shown in bold (multicastGroupAddress and multicastGroupPort) to reflect the multicast group and port in your environment.

    <!--<cacheManagerPeerProviderFactory 
class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" 
properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, 
multicastGroupPort=4446, timeToLive=32"/>

<cacheManagerPeerListenerFactory 
class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory"/>
-->
  • Uncomment the following section of the file.
    <!--
<cacheEventListenerFactory
class="net.sf.ehcache.distribution.RMICacheReplicatorFactory"
properties="replicateAsynchronously=true, replicatePuts=true,
replicateUpdates=true, replicateUpdatesViaCopy=true,
replicateRemovals=true"/>
<cacheEventListenerFactory
class="com.unicacorp.uap.common.cache.PlanCacheEventListenerFactory" />
-->
  • If the following lines are present in the file, remove them.
    <bootstrapCacheLoaderFactory
class="net.sf.ehcache.distribution.RMIBootstrapCacheLoaderFactory"/>
