Maximum number of instances in 1 CapeDwarf (multi-instances)

[giacomo.genovese]

Hi,

Which is the max number of instances that can run on the same CapeDwarf at the same time?

Thanks,

Giacomo.

Do you mean applications or cluster instances?

Both can be as many as you like.

[giacomo.genovese]

Applications.

Anyway, I'm trying to run 2 applications and I receive error about clustering.

I need to solve it, could you help me?

Thanks.

Two applications in a 2 node cluster?

Sure, post any issue details here.

Hi,

This is the command that I use to run the second application (GAE app):

     "sudo Capedwarf/bin/standalone.sh -c standalone-capedwarf.xml -Djboss.server.base.dir=Capedwarf/standalone1/ -Djboss.socket.binding.port-offset=10000 -Djboss.node.name=node1"

Here the Error:

Thanks again.

[alesj]

Uh, no idea ... what does HornetQ forum say?

Or perhaps Google for this kind of error.

As this is HornetQ specific, not CapeDwarf.

[jbertram]

My first thought is you need to set these two elements in your <hornetq-configuration>:

<cluster-user>myClusterUser</cluster-user>
<cluster-password>myClusterPassword</cluster-password>

Where "myClusterUser" and "myClusterPassword" are strings of your choosing.

A HornetQ cluster won't form with the default clustering credentials for security reasons.

[alesj]

Here?

* https://github.com/capedwarf/capedwarf-testsuite/blob/master/integrate-cd/src/main/resources/standalone/configuration/standalone-capedwarf.xml#L374

jbertram but i'm wondering how/why our cluster tests pass, w/o this change? ... weird

[jbertram]

Yes, that's the place, alesj.

Perhaps you have <security-enabled>false</security-enabled> on your cluster tests and that's why they pass?

[giacomo.genovese]

I modified the standalone-capedwarf.xml writing the same password for both applications and It doesn't display any error.

I'm going to test if they work good.

Thanks a lot!
