Subject [jira] Commented: (AMQ-2172) QueueBrowser doesn't browse the entire queue
Date Wed, 08 Jul 2009 16:46:07 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=52744#action_52744

Gary Tully commented on AMQ-2172:
---------------------------------

the current behavior of a browser is controlled by the maxBrowsePageSize PolicyEntry value.
It defaults to 400. This limits the amount of messages that need to be in memory for the browser
snapshot. Increasing this should allow more messages to be browsed.

> Browsing a queue only seems to "snapshot" the first few messages in the queue when there
are lots of messages in the buffer.  See attached test case.
