'm actually using jms url to connect my client app to hornetQ server, like jms://localhost:5445.  Is that a problem?

there is no such thing as a JMS url, if you mean you are using JNDI then you should use the host and port of the jndi server, 1099 by default i think.

Maybe I was using the wrong terminology, sorry.

When I said JMS url, I meant creating the JMS ConnectionFactory object without using JNDI. Please refer to <7.6. Directly instantiating JMS Resources without using JNDI>  in HornetQ manual.

There's also a concrete exmple in <Chapter 16. Configuring the Transport> .

Hope this will help.

if you are using the direct method of creating the factory then you also need to configure as in the config file, so factory.setHA(true) etc etc

Hi Andy,

Thanks a lot for your quick response.

This is how I create the factory:

Map<String, Object> connectionParams = new HashMap<>();
            connectionParams.put(TransportConstants.PORT_PROP_NAME, port);
            connectionParams.put(TransportConstants.HOST_PROP_NAME, host);
            TransportConfiguration transportConfiguration = new TransportConfiguration(NettyConnectorFactory.class.getName(), connectionParams);
            return HornetQJMSClient.createConnectionFactoryWithHA(JMSFactoryType.CF, transportConfiguration);

I think createConnectionFactoryWithHA will do the job in the case, right?

Thanks,

Hao

I finally figured it out by myself.

To implement the static cluster, in hornetq-configuration.xml, you can remove the 'discovery group' part entirely, just add a connector/acceptor pair (let's call it 'netty') for client's connections, another pair (let's call it 'netty-live' if this is the live server) for the backup server's connection and a connector (let's call it 'netty-backup' if this is the live server) for the live connecting to the backup, then refer 'netty-backup' in the 'static-connectors' section. Do the similar thing to the backup sever and in hornetq-jms.xml, you just need to refer the 'netty' connector and that's it.

Hope this helps,

Hyrax

HI,

if possible could you please post the configurations, i am also facing similar kind of issue.

Thanks in advance

I recommend you start a new thread and describe your use case and what exactly you need.  Commenting on old threads is rarely a good idea.

Hi Justin,

I use data replication of HA modes.

I use jndi to lookup ... I set both live and backup server url in provider url in jndi properties. My application connect to live server and run well. Then I shutdown live server. Backup server startup and messages in live server replicated to backup server. But in my application side, it cannot connect to the backup server again.

below is the stack trace:

Did you not see my previous message?

Hi Justin,

I meet a new problem now.

I found the message consumer failed to start up after fail over. And find duplicate message after fail over.

I  run a application connect to live and backup sever. There are 12 consumers on MFQueue in live hornetQ server. I send 600 messages to MFQueue. When the queue is processing, I shutdown live server and backup server become live one.But I found only 6 consumers on MFQueue in backup server and I found 608 messages consumed at last. So there are 8 duplicate messages and 6 consumer lost after fail over. Can you help to check my configuration and advise on it. Thanks.
