[jboss-user] [JBoss Messaging Users] - Re: paging problem with orderingGroup enabled

Fri Aug 28 05:46:15 EDT 2009

Hi Howard!

I investigated my problem more deeply.

First I have to say, that the OrderingGroup of bridged messages are overwritten by the setting in the connection factory.
Not that nice I think.
So I send a message with ordering group G1 to a Queue. This message is bridged to another server where ordering group attributes are set at the connection factory to group GDefault. Then the messages have the group GDefault iso G1. 
Bug or a feature :-) ?

Second: 
I have added some tracing to the OrderingGroupMonitor to see what is registered and what completed.

While my server starts up it loaded the first 20 paged messages and adds them to the OrderingGroupMonitor. Then it starts handling the messages and calls completed on the Monitor, which removed the ref from the group.
After 5 messages are handled the JDBCPersistenceManager loads the next 5 paged messages and adds them.
That behaviour is fine!
But if a message is added to the queue (new message comes in) which have the same orderinggroup, this is registered too on the Monitor. But the message itself is added to the DownCache. 
This seams to be a bug or?
If a message is added to a "full" queue which is paged then this should not be registered to the monitor, or?

Maybe this is the reason, why the delivery stops....

The behaviour you can see below:
