问题 I am trying to setup ActiveMQ persitenceAdapter to an Oracle 11g (11.2) database. When starting ActiveMQ through the Tanuki wrapper I am getting the Cannot load JDBC driver class 'oracle.jdbc.driver.OracleDriver' exception.

由 让人想犯罪 __ 提交于 2019-12-13 01:06:40
问题 I installed R 's Rjms package as I want to send messages to an ActiveMQ message queue already set up (called test ) for me. As Rjms is not on CRAN, I installed it from github using the directions in ActiveMQ package for R. However, I noted two things. When installing Rjmsjars , I received a warning saying No man pages found in package ‘Rjmsjars’ . I think this is likely unrelated, but I wanted to include this just in case. library(devtools) install_github("cran/Rjmsjars") install_github(

Notify ActiveMQ producer if consumer on the destination is down

由 百般思念 提交于 2019-12-12 19:09:02
问题 I am using ActiveMQ messaging broker and I have a requirement where the producer application would want to know if the consumer application consuming on the particular destination is up or not? How can I achieve this? Thanks! 回答1: You should checkout Advisory messages. It's a topic you can subscribe to if you want updates on such events. Specifically the topic: ActiveMQ.Advisory.NoConsumer.Queue should be of interest. You need to enable it broker side though using the destination policy

由 房东的猫 提交于 2019-12-12 16:18:35

You can
