Managing Inactive Offline Durable Subscription

[tras <tr...@ccbilleu.com>]

Using activemq version 5.7.0A component which had a durable subscription to a
VirtualTopic was undeployed. This component was then restarted and the
durable subscription was given a different client id. This is causing an
issue of storage since the previous subscription with the old client id is
still consuming all events.Deleting the subsciption from UI web admin is not
working (storage is not going down and on restart subscription is showing up
again). Adding the following offlineDurableSubscriberTimeout="86400000"
offlineDurableSubscriberTaskSchedule="3600000" in the activemq.xml and
restarting activemq still doesn't delete the automatically the
subscription.Is there a way one can delete an offline durable topic
subscriber?Note: The Topic is being used by other active durable subscribers
having different client ids but same subscription names.

Also, you could write a utility program that would connect with that client
ID and subscription name and perform an unsubscribe on the consumer's
behalf.  You're essentially impersonating the consumer for this one
purpose, but given what you're doing, that's probably not an issue.

Have you looked in JConsole to see if there are any actions exposed via JMX
that would allow you to remove that subscription?  I've never run 5.7.0 so
I can't say whether anything is available in that version (or any version,
for that matter), but it's where I'd look.

Thanks for your reply. Yes true, however the issue is that that durable
client ID cannot be deleted and messages are not being consumed since its
offline thus we are running out of storage. This means that when using
activemq 5.7, we are stuck with a useless offline subscription.

Is there a workaround we can do to delete that offline subscription, until
we upgrade the version of activemq from 5.7?

As described at the bottom of
http://activemq.apache.org/how-do-durable-queues-and-topics-work.html, if
you want durable subscriptions to work, you can't allow the client ID to
change following a restart.  Set it yourself, explicitly, to guarantee it
doesn't change.
