Lucee ehCache distribution for beginners

dev support

I’m trying to configure cache distribution between two instances.

For this I’ve created test appliaction:

Application.cfc

component {
    this.cache.connections["testcache"] = {
        class: 'org.lucee.extension.cache.eh.EHCache',
        bundleName: 'ehcache.extension',
        bundleVersion: '2.10.0.36',
        storage: false,
        custom: [
            "bootstrapAsynchronously":"true",
            "replicatePuts":"true",
            "automatic_hostName":"",
            "bootstrapType":"on",
            "maxelementsinmemory":"20000",
            "manual_rmiUrls":"//10.10.10.10:40001",
            "automatic_multicastGroupAddress":"",
            "distributed":"manual",
            "replicatePutsViaCopy":"true",
            "memoryevictionpolicy":"LRU",
            "maximumChunkSizeBytes":"5000000",
            "timeToIdleSeconds":"21600",
            "automatic_multicastGroupPort":"4448",
            "listener_socketTimeoutMillis":"120000",
            "timeToLiveSeconds":"86400",
            "replicateRemovals":"true",
            "manual_addional":"",
            "replicateUpdatesViaCopy":"true",
            "automatic_addional":"",
            "replicateAsynchronously":"false",
            "maxelementsondisk":"10000000",
            "listener_remoteObjectPort":"",
            "asynchronousReplicationIntervalMillis":"1000",
            "listener_hostName":"",
            "replicateUpdates":"true",
            "manual_hostName":"",
            "automatic_timeToLive":"unrestricted",
            "listener_port":""
        ]
      , default: 'object'
   };
}

index.cfm

<cfscript>
    variables.res = cacheGet('Test');
    if (isNull(variables.res)) {
        variables.res = 'Cache is empty';
    }
    writeOutput(variables.res);
</cfscript>

put.cfm

<cfscript>
    cachePut('Test', 'Hello, World!');

    writeOutput('Cache put!');
</cfscript>

delete.cfm

<cfscript>
    cacheDelete('Test');

    writeOutput('Cache deleted!');
</cfscript>

In Applicationc.cfc on instace A I provide rmiUrls “//inst.ance.B.ip:40001” and on instance B I provide rmiUrls “//inst.ance.A.ip:40001”

And now I’m trying to execute put/delete and check cache on both instances but for my no pur neither delete doesn’t synchronized on any of them(

What I’ve missed? What I’m doing wrong?

OS: Windows 10 (10.0) 64bit
Java Version: 11.0.22 (Oracle Corporation) 64bit
Tomcat Version: Apache Tomcat/9.0.86
Lucee Version: 6.0.4.10

Hey did you have any luck getting this working? We’re in a similar position - trying to set up manual replication between two servers, and it’s seemingly not working with any combination of settings. We’ve also tried to enable some logging to see where it’s not working, but couldn’t get that going either.

We’re on Windows 2016/IIS with the latest 6.2.0.321 release and the latest released ehcache extension version.

If you or anyone else has any ideas, they’d be appreciated :slight_smile:
