Hi, A little over a year ago, I went through a process setting up terracotta caching server for an application that is using cf clustering.. three instances of coldfusion powering the application, and I wanted to be able to efficiently cache data between instances. This worked really well, but now I'm more or less disassocaited with the company and they've asked me to set up TerraCotta again on their new server, which is running Coldfusion 10.
Things are different, of course, but much the same.... Here's what I've done. I installed the latest version of TerraCotta open source (3.7.5) which comes with a newer version of ehcache. I copied all these jar files into each instances libf older and renamed any older versions with a .old extension ehcache-core-2.6.6.jar ehcache-terracotta-2.6.6.jar slf4j-api-1.6.1.jar slf4j-jdk14-1.6.1.jar slf4j-log4j12-1.6.1.jar terracotta-toolkit-1.6-runtime-5.5.0.jar Then modified the ehcache.xml as follows: I added this line above my defaultcache: <terracottaConfig url="http://localhost:9510"; rejoin="true" /> I added this section BELOW my defaultCache, which essentially adds a new cache region named "distributedCache" <cache name="distributedCache" maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="86400" timeToLiveSeconds="86400" overflowToDisk="false" diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="3600" memoryStoreEvictionPolicy="LRU" clearOnFlush="true"> <terracotta clustered="true" > <nonstop immediateTimeout="true"> <timeoutBehavior type="noop" /> </nonstop> </terracotta> </cache> Now that I've done all this, I did some testing with a cf page that looks like this... if the request is made on instance 2, put something in the cache, then retrieve it and display it. If it's on another instance, just retrieve the value and display it. <cache name="distributedCache" maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="86400" timeToLiveSeconds="86400" overflowToDisk="false" diskSpoolBufferSizeMB="30" maxElementsOnDisk="10000000" diskPersistent="false" diskExpiryThreadIntervalSeconds="3600" memoryStoreEvictionPolicy="LRU" clearOnFlush="true"> <terracotta clustered="true" > <nonstop immediateTimeout="true"> <timeoutBehavior type="noop" /> </nonstop> </terracotta> </cache> This doesn't fail, but it doesn't appear to be using the terracotta server, because the item is not available on the other instances. I don't know where to go from here. As always, your combined help is appreciated!
