HP ServiceGuard ActiveMQ failover

Does anybody has experience using HP ServiceGuard package failover to provide HA? I would like to use it instead of a Master/Slave configuration. It seems to me that both configuration should be roughlty equivalent (with Master/Slave probably being faster to failover). Any remark/advice on that

Re: HP ServiceGuard ActiveMQ failover

Basically you run your application on a virtual host. If the host fails, the virtual host is brought down and restarted on a different hardware. Since it's HA, all information from the filesystem are preserved and the new host assumes the role of the old one (same ip, ...). It seems to me that

Mail queue

I new to JMS and messaging in general and would like a little advice. In my application, I have a java webapp that sends e-mails. For reasons too complicated to explain, my client wants an hour lag time between the time the e-mail is created and the time it is sent, so I need to park it

Pythin and MapMessage

Has anyone gotten PyActiveMQ to work with ActiveMQ and MapMessages? Are there known bugs with this configuration? One of our Python folks is pushing me to use TextMessages instead of MapMessages because (he claims) MapMessages don't work in Python. Thoughts? -- Elliotte Rusty Harold [EMAIL

Re: ClassCastException w/ tomcat JND

Thanks James, indeed this was the problem. I previously had the jms.jar included in my app's .war file, but I thought that it might have been causing the issue so I took it out yesterday, but the problem was still occuring. Lo and behold I did a search of my tomcat directories and I found the

Re: Mail queue

I would approach this using persistent messages. Your webapp creates a persistent message adds the time (as a property maybe) at which the message should be sent as email and puts it on a queue. Another application can regularly poll the queue for messages that are ready to be emailed.

Re: Mail queue

Somebody proposed in a different thread to use a MessageSelector to only select the messages that are at least an hour old. You could set a message-property to System.currentTimeMillis() and then create a selector with SendTime +(System.currentTimeMillis()-360). You'd have to recreate your
