Hello Boris,
thank you for replying to my email/questions.
OK, I understand that I have to make my queue and messages durable, I have made
all my queues durable (please see the attached virtualhosts_with_bdb.xml.txt
file (renamed to .txt so that email does not count it as spam). Still I have
the same situation.
My log file says queues are durable.
steps:
1. start server
2. put two messages
3. veryify messages with MessageBrowser that there are 2 messages
4. shutdown server
5. start server
6. MessageBrowser shows there are 0 (zero) messages
How do I make my messages durable? any setting on the message?
Many thanks in advance.
best,
Mahmoud

Greetings,
Could you please check the following:
1. queue created as --durable
2. the messages sent as durable messages (message header property) to the
broker.
If so, the queue should store messages after broker restart.
Regards,
Boris

Subject: question of BDB persistence
Hello all,
I have been able to configure qpid-0.10 to work with BDB persistent store on
centos linux environment.
Let's say that my queue has 2 messages (put in message queue by a producer,
confirmed by message browser), when I shutdown the server and the restart the
server, all messages from the message queue have disappeared. Is this the
normal way to work, or should I see my 2 messages because I am using BDB as a
persistent storage.
Is there any parameter/configuration I have to set up to preserve persistence
during shutdown and restart of the server.
thank you.
Mahmoud
