Description

We run the brokers on nodes RGC001 and RGC002, both with the following configuration:

log-enable=info+
log-to-file=/var/lib/qpidd/data/15399/qpidd.log
log-to-syslog=no
auth=yes
acl-file=qpidd.acl
realm=QPID15399
data-dir=/var/lib/qpidd/data/15399
pid-dir=/var/lib/qpidd/data/15399
port=15399
num-jfiles=4
jfile-size-pgs=1
tpl-num-jfiles=4
tpl-jfile-size-pgs=1
cluster-name=QPID15399
cluster-url=amqp:tcp:RGC001:15399

1. 1. 1. on machine RGC002 the URL is amqp:tcp:RGC002:15399
         cluster-username=admin
         cluster-password=admin

I start the broker on RGC001 and add an exchange and a queue:

RGC001 $ qpid-config -a admin/admin@localhost:15399 add exchange direct eurex.EXCHANGE --durable
RGC001 $ qpid-config -a admin/admin@localhost:15399 add queue eurex.QUEUE --durable --limit-policy reject --max-queue-count 10

These can be listed e.g. by qpid-config:

RGC001 $ qpid-config -a admin/admin@localhost:15399 queues eurex
Queue Name Attributes
===================================
eurex.QUEUE --durable --file-size=24 --file-count=8 --max-queue-count=10 --limit-policy=reject

RGC001 $ qpid-config -a admin/admin@localhost:15399 exchanges eurex
Type Exchange Name Attributes
=============================================
direct eurex.EXCHANGE --durable

Now I start the broker on RGC002 and check whether qpid-config shows me the queue and the exchange:

RGC002 $ qpid-config -a admin/admin@localhost:15399 queues eurex
Queue Name Attributes
===================================
eurex.QUEUE --durable --file-size=24 --file-count=8 --max-queue-count=10 --limit-policy=reject

RGC002 $ qpid-config -a admin/admin@localhost:15399 exchanges eurex
Type Exchange Name Attributes
=============================================

I.e. already in this simple scenario there is a problem with the exchanges.
The exchange is also not shown by qpid-stat and qpid-tool.

Now I ran qpid-cluster to check whether the brokers see each other, first on RGC001:

RGC001 $ qpid-cluster admin/admin@RGC001:15399
Cluster Name: QPID15399
Cluster Status: ACTIVE
Cluster Size: 2
Members: ID=192.168.178.1:15051 URL=amqp:tcp:RGC001:15399
: ID=192.168.178.2:24407 URL=amqp:tcp:RGC002:15399

Now on RGC002:

RGC002 $ qpid-cluster admin/admin@RGC002:15399
Cluster Name: QPID15399
Cluster Status: ACTIVE
Cluster Size: 2
Members: ID=192.168.178.1:15051 URL=amqp:tcp:RGC001:15399
: ID=192.168.178.2:24407 URL=amqp:tcp:RGC002:15399

Finally, to show that the exchange still exists in broker on RGC002, I try to create it but now with type topic:

RGC002 $ qpid-config -a admin/admin@localhost:15399 add exchange topic eurex.EXCHANGE --durable
Failed: SessionException - exception(error_code=530, command_id=serial(56), class_code=7, command_code=1, field_index=0, description=u'not-allowed: Exchange declared to be of type direct, requested topic (qpid/broker/SessionAdapter.cpp:116)', error_info={})

This problem has also been reported as Red Hat service request #1960092.
