Re: Artemis cannot find LIBAIO, although it is installed

Problem is finally resolved. There is an error in the documentation: This page: https://activemq.apache.org/artemis/docs/2.3.0/libaio.html mentions a file libActiveMQAIO64.so, which is /incorrect./ The distribution is shipped with a file called libartemis-native-64.so, which is to be used. In

The entire code base except Artemis is under our control. The vast majority of the messages are delivering fast ,more than 99.999. The use case: An API submits a POST request, we form a message and stick it into a queue. The queue has 10 listeners. When these listeners receive a Message, they wri

Re: Artemis cannot find LIBAIO, although it is installed

We recompiled and reinstalled the library, but when the process starts, we still see " libaio is not available, switching the configuration into NIO" in the log file. Is there a way to tell that the library is installed and functions properly? Thanks -- Sent from: http://activemq.2283324.n4

Messages delayed for no reason

Some of the messages sit in a queue, while we have available and registered listeners. After a few hours, the messages are delivered. What can be the cause of that? We use Artemis embedded using the JavaLite Async wrapper: https://github.com/javalite/activeweb/blob/master/javalite-async/src/mai

Re: Artemis cannot find LIBAIO, although it is installed

Hi, Clebert. This is exactly what I did. However, my admin has doubts in a way he compiled and installed the lib. Let us poke around a bit. Is there a sure way to determine that the system library is properly installed and functioning without running a broker? Thanks, -- Sent from: http://

haha, you are correct! Not only I should not use broker for error messages, but having them in the DB is much more convenient. I could re-queue them, or just delete. Thanks for the link to the antipattern! -- View this message in context: http://activemq.2283324.n4.nabble.com/How-does-Apache-A

Re: How does Apache Artemis manage heap space (RAM)

Thanks for the info! This makes sense. I explored the configuration in the debugger, and it does not seem that Artemis may allocate more than 200MB of heap, but keeping all these error messages in the queue might not be the best idea in the first place. Will Artemis use heap for DLQ?

How does Apache Artemis manage heap space (RAM)

In our projects, we use two queues, one for normal processing, and another for errors. The "error" queue sometimes gets filled with "error" messages, which are sitting there, until a human checks them out. In some cases, the "error" queue fills out with a lot of messages, and then the JVM runs out
