Re: What can be reason of 460%+ memory usage limit

I believe you're correct. If PFC is disabled, when the store cursor checks limits, it checks only the memory percentage of its own MemoryUsage and compares it to the high water mark. Otherwise if PFC is enabled, it checks whether the MemoryUsage is full but the isFull method also checks its

Re: 回复: request for java client for Apollo

You can also use any of the ActiveMQ 5.x clients, as Apollo supports OpenWire. The support for OpenWire isn't yet in the complete state, but a majority of the features are there. I'm working on the initial documentation, and have a project set up here to demo some of the features:

Turn on the JIRA SVN plugin for ActiveMQ Apollo?

Hiram, and others... would it be possible to turn on the JIRA+SVN plugin so it correlates SVN commits with JIRAs in the Source tab like ActiveMQ has it? Thanks, Christian - http://www.christianposta.com/blog -- View this message in context:

Re: Usage Manager memory limit reached

This should really be a new thread. take a look at http://activemq.apache.org/message-cursors.html you have producer flow control set to true, so your producers will be throttled if there is no space available. using message cursors, you can get the messages spooled to disk so the slowest

Apollo relies on JAAS LoginModule to handle authentication. Out of the box, there is support for file-based authentication: http://svn.apache.org/viewvc/activemq/activemq-apollo/trunk/apollo-broker/src/main/scala/org/apache/activemq/apollo/broker/security/FileUserLoginModule.scala?view=markup

From what I understand, Apollo uses the idea of consumer credit window to decide how many messages to send down to the client that haven't been ACKed. use the credit header in your stomp frame to set the credit window:

Abimael, Just to follow up on what Matt said, the messages in the log files will only be deleted once they're *all* consumed. If you have a log file where all but one message is consumed, the log file will stay around until the last message is consumed. Thanks, Christian -

Amir, I figured it out. The patch you submitted was not the correct one, but very much on the right track. I'll update the JIRA with what I found. As Gary mentioned, this module could use some unit tests, so I'll write those as well. The link to your JIRA issue is here:

Using ActiveMQ vs Weblogic JMS

Hi all, my first post to this mailing list. I'd like to get some ideas about what message broker should I use for a messaging integration system. I realize ActiveMQ may be good for this, but I'd like to get some feedback from others that may have used Weblogic's JMS provider (or both) and give me
