Integrating Coherence with ATG

Follow the steps to integrate Coherence with ATG.

1. Configure the coherence cache type you want to use. In this case using distributed cache.
/atg/adapter/gsa/externalcache/GSACoherenceManager.properties
defaultCacheNamePrefix=dist-cache

2. Configure the repository to use Coherence external cache
/atg/commerce/catalog/ProductCatalog.properties
cacheLocality=external

3. Modify the customCatalog.xml item-descriptors to use coherence. By default it uses simple.
cache-mode="distributedExternal"

4. Copy the below jar files to <server-location>/lib
C:\ATG\ATG11.2\DAS\lib\atg-coherence-classes.jar
C:\ATG\ATG11.2\DAS\lib\coherence.jar

5. Add the below java startup args to the server.
COH_OPTION="-Dtangosol.coherence.cacheconfig=coherence-cache-config.xml -Dtangosol.pof.enabled=true -Dtangosol.pof.config=atg/adapter/gsa/externalcache/config/atg-pof-config.xml -Dtangosol.coherence.cluster=atg-coh -Dtangosol.coherence.clusteraddress=224.3.7.0 -Dtangosol.coherence.clusterport=3059"
JAVA_OPTIONS=$JAVA_OPTIONS:$COH_OPTION

CLASSPATH="/opt/app/workload/WebLogic/OCE_OS/lib/coherence.jar:/opt/app/workload/WebLogic/OCE_OS/lib/atg-coherence-classes.jar"
export CLASSPATH
