Hello Active MQ users/developers ,
Our application uses non persistent
embedded broker ,durable subscribers , topic publishers . The active mq
version is 4.1.1(release version). There are two topic publishers and
two durable subscribers respectively.
In your previous responses, you specified that for durable subscribers
active mq maintains a queue of messages (Message Queue). For each of
the durable subscribers, a queue of references is maintained , the
references point to the messages stored in Message Queue.
Are these queues maintained in RAM or on the disk ?
There is TTL of 5 minutes on all the messages.
What is the behavior if the messages are not consumed after 5 minutes
? There is JIRA issue AMQ-1112 (Messages still exist after TTL). Will
the messages keep accumulating in the message queue and the
corresponding references in the individual queues ?
if this is the case will active mq occupy a lot of disk space.?
The active mq data folder is always around (40.7-40.8 MB).
This issue is fixed in 5.0 snap shot, cannot upgrade to snap shot
version, as Iam not sure how stable it is. We are going into production
next month.
Please let me know, as to what can be done in this regard. Would
switching to non durable subscribers solve the problem ?
is there a tool which I can use for browsing through active mq's
Message Queues ?
thanks,
Suchitha.
