> ------------------------------------------------------------------------------------------------------------
>
> Key: AMQ-2057
> URL: https://issues.apache.org/activemq/browse/AMQ-2057
> Project: ActiveMQ
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 5.2.0
> Environment: Windows XP. Broker and client running on different
> machines communicating via TCP
> Reporter: Ian Beaumont
> Fix For: 5.4.0
>
>
> I'm trying to queue a large number of messages in a single transaction. It
> seems that the broker needs to have enough heap space available to store all
> these messages to in memory at one time before I can commit the transaction.
> I have set producerFlowControl to false.
> I'm looking at ActiveMQ as a replacement for MQSeries - and in MQSeries the
> messages in the transaction would be written to the store as they came in,
> and then if the transaction was then rolled back they would then be removed.
> It appears that the messages in ActiveMQ are not placed in to the store unitl
> the transaction is commited. Ideally they should be put in the store as they
> come in, but marked as uncommitted.
> Sorry if my understanding of how things are working is wrong, but I've posted
> a few messages on the subject and have had no replies.
