ActiveMQ Master/Slave on Weblogic - vm transport issue - weblogic

I am trying to configure ActiveMQ master/slave setup on a single WebLogic machine. The problem is when I start Managed Server1 it successfully connects to vm transport and everything works perfectly, but when I start Managed Server2 I am receiving the following errors in broker logs
INFO 2016-September-27 10:08:00,227 ActiveMQEndpointWorker:124 - Connection attempt already in progress, ignoring connection exception

Please help, I am stuck with this.

I still don't see the reason for the slave within the same VM. I suggest you reach out to an ActiveMQ expert consultant to validate your architecture.
However, I think I can help you move a little bit closer to this issue:
There is a fundamental miss understanding here.. the vm url is broken down like this:
vm://${brokerName}?option=value,etc
The first time you create vm://localhost?create=true.. you have created a broker
The second time you reference vm://localhost?create=false.. you have created a client connection to the first broker.
To get two brokers, you'd need two different vm://${brokerName}?create=true

I want to connect aws-Kafka with s3 using confluence connector on my ec2 server. I try to configure everything like in tutorials.

My spring-boot service using rabbitmq to send push notification asynchronously. So push payload publish/received via rabbitmq then send on FCM. However, this connection is working for last one year without any problem. But this morning rabbitmq server is restarted as follows
rabbitmq stop
kill process bean ( related erlang )
rabbitmq start
after that we restart spring-boot service successfully, and health-api shows rabbit-up status.
but having error when trying to send push.
application properties configuration.

Open MQ broker won't start

We're running Glassfish 4.1.1 (Payara) with mq 5.1.1. It's a HA setup with load balancer and cluster.
Glassfish is running ok. Problem is that MQ won't start.
I think that a remote MQ is starting. I can do imqcmd list bkr -b and I get successful results.
However when I do imqcmd list bkr (or imqcmd list jmx, without -b hostname) I get:
Host Primary Port
-------------------------
localhost 7676
WARNING: [C4003]: Error occurred on connection creation [localhost:7676]. - cause: java.net.SocketException: Connection reset
Error while connecting to the broker on host 'localhost' and port '7676'.
I'd like to get rid of the error, and see my network ip instead of localhost.
Also GF server.log gives this:

I'm wondering where the directory that it is unable to make is configured.
I've been debugging this for days. I need to know where to configure the ip for the embedded broker. I also need to know where to set up the jmxrmi url.
any help would be appreciated. Thanks!
I found the solution to this problem. We had a broken symlink to the openmq application directory, within the Glassfish application directory. On domain startup, Glassfish could not find mq and therefore could not start the embedded broker. Once we fixed the symlink, the embedded broker started up on glassfish domain startup (asadmin start-domain).
I knew the embedded broker was not starting because the "imq" folder was not being created in <domaindir>/
Check for those broken symlinks!!

activemq failover using multiple instances in master slave mode on same linux machine

I have setup ActiveMQ mulitple instances to achieve failover in master slave mode in windows.
While setting up the same i just created 3 instances under bin folder without changing any port and started all 3 instances one by one. First instance became master and remaining were in slave mode until I stopped master instance.
Now I am trying to achieve the same in Linux environment. First instance starts successfully but when I start second instance in a different window it throws below error:

I am using ActiveMQ 5.14 version.
If anybody has encountered a similar issue, kindly provide your inputs.
To get multiple instances of ActiveMQ running on the same machine, you need to change the ports that they try to open. There are (at least) 3 ports that need to be changed:
The transportConnector ports that accept messaging traffic. These are defined in theactivemq.xml file. Typically you only need the openwire one - this is 61616 by default; I usually change this in the other ActiveMQ instances to 61626, 61636 etc. You can usually comment out the others if you don't intend to use them.
The Jetty HTTP port. This is defined in the jetty.xml file. The default is 8161, set the next ones to 8162, 8163 etc.
The JMX port. This one's a bit tricky, as you need to stick a piece of config into the activemq.xml to explicitly define it as follows:
<managementContext>
<managementContext createConnector="true" connectorPort="1099"/>
</managementContext>
You can then change this to 1199, 1299 on the other instances. Hope this helps.

How can I change which address Datastax agent will try to connect to?

My Cassandra instances are not listening on 127.0.0.1. When I start datastax-agent I find this in logs:

How can I change which address the Datastax Agent connects to? I have tried setting local_interface in the agent's address.yaml (and restarting agent), but that doesn't seem to work.
The secret was to set rpc_address to 0.0.0.0. Cred to LHWizard for pointing this out.
