Hi all,
I'm working on MQSeries Publish\Subscribe broker.
WebSphere MQ --- V5.3.0.2 with CSD04 Patch...
MA0C support pac ---- MQSeries Pub/Sub Broker
I have written an application to register publishers and subscribers. Once I register all publishers and subscribers using my application and run the following command, i can see all my subscriptions information like RegistrationQMgrName, RegistrationQName etc as below and everything is working fine. But my problem is .... If I run the amqspsd -m SSP.EVENTS.QMGR command once again after few hours I see some data of the subscriptions is being lost. you can see the differences below...
info...running the following command immediately after registration of subscriptions....
> ./amqspsd -m SSP.EVENTS.QMGR

| I'm not sure how to read the output to know if a subscriber is durable or non-durable. My guess as to the difference is that you registered some non-durable subscribers. You didn't unsubscribe them. MQ cleanup ran, noticed that they were gone, and cleaned them up. |

Hi bower5932,
Let me give some more info.
while registration, I'm not specifying any Registration options except the strem queue, Topic and subscriber queue name...
If I want register a subscription as durable, do I have to specify any registration options like MQREGO_PERSISTENT etc..while registration?
how can I make my subscriptions as durable subscriptions ?
thanks

The expiration of the subscription is determined by the expiry field of the message descriptor (MQMD) of the message containing the subscription.
For a durable subscription, set the Expiry field to MQEI_UNLIMITED.
