After a few more hours I got some new results but also lot of confusion. First
I switched in servicemix.xml the flow configuration to JMS as default (maybe
this should also be outlined on the SMX homepage). Now the cluster seems to
work. I am using a environment where SOAP requests are entering the ESB via the
HTTP BC. These requests are then forwarded to the ODE SE which sends a
reformatted message to the Advanced JDBC component.
Now I deployed the HTTP BC, the ODE SE, JDBC BC on one host of the cluster
And only http BC and JDBC BC on the other host of the cluster
On one host in the cluster (where all components are installed ) I now
experience the right behaviour. The JDBC query is done in round robin fashion
between the two hosts like descriped in the Flows section of the SMX user
manual.
On the other host where ODE SE is not installed I get the that the service is
not registered.
HttpComponent | emix.common.AsyncBaseLifeCycle 626 | Created

DefaultBroker | rvicemix.jbi.nmr.DefaultBroker 344 | ServiceName
({urn:/NameInfo.wsdl}NameService) specified for routing, but can't find it
registered
Why ist he request not forwarded to the other host of the cluster of brokers?

Betreff: SMX Cluster with HTTP and ODE Component
I'm trying to get a SMX cluster running consisting of two SA and two SMX
instances on two different hosts. One SA is including the http BC and the other
one the ODE engine. Running both SA in the same SMX instance is not problem and
everything works fine. Putting the two SA on different machines the query
results in the following debug output:
10:31:16,920 | DEBUG | btpool0-1 | HttpComponent |

The cluster is using a static configuration and the debug output is also
showing communication between the instances after the second one is starting:
10:03:37,841 | DEBUG | ActiveMQ Session Task | JMSFlow |

I have no idea what is the cause for it. Thanks for help in advance.
