Websphere MQ Durable Topic Timeout

Question

I'm connecting to a Websphere MQ topic with a durable subscription using Spring:

<jms:message-driven-channel-adapter
    channel="springChannel"
    destination-name="wmqTopic"
    connection-factory="connectionFactory"
    destination-resolver="destinationResolver"
    subscription-durable="true"
    durable-subscription-name="myDurableSubscriptionName" />

Since this is a durable subscription, I'm concious that whilst the application is not subscribed to the topic in WMQ the messages for next time I connect are piling up either on disk or in memory. I'm concerned that as a result WMQ will run out of either memory or disk space unless a timeout is specified somewhere.

Does anyone know what my options are for specifying the timeout? Should it be in the message-driven-channel-adapter or WMQ, or should it be an expiry set on the message before publication?

Answer 1

or should it be an expiry set on the message before publication?

Yes.
