Subject [jira] Commented: (AMQ-1112) remove expired messages from Store and update Message cursors
Date Sat, 16 May 2009 01:32:51 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-1112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=51726#action_51726
] 

Benjamin Darfler commented on AMQ-1112:
---------------------------------------

I created a quick python script that hits the web ui, finds all the queues and then browses
each which causes any expired messages to actually be removed from the queue.  We put this
as a cron job that runs every 5 min.

If you pass no arguments it looks at localhost otherwise you can pass in as many host names
as you want to hit.

I tried attaching it but no go so here is the source.

--------------------------------------------------------------------------------

#! /usr/bin/env python

import sys, urllib2, re

pattern = re.compile('browse.jsp\?JMSDestination=([a-zA-Z.]*)')

def expireMsgs(host='localhost'):
    url = 'http://' + host + ':8161'
    html = urllib2.urlopen(url + '/admin/queues.jsp').read()
    for queue in set(pattern.findall(html)):
        urllib2.urlopen(url + '/admin/browse.jsp?JMSDestination=' + queue).read()

if not sys.argv[1:]:
    expireMsgs()
else:
    for arg in sys.argv[1:]:
        expireMsgs(arg)
