[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Journal Clean up / Compactor

by clebert.suconic＠jboss.com

The problem is when one record is *not* deleted. f1: A1, A2 (A2 won't be deleted for a while) f2: D1, A3, A4 f3: D3, D4 A5 A6 f4: D5, D6, A7, a8 f5: d7, d8, A9, A10 F2 won't be reclaimed because f1 is not completed yet. F3 won't be reclaimed because it has waiting records on F2... F4->F3, F5->F4 If I phisically removed A1 from f1 (as it is deleted & confirmed already), f2, f3, f4 and f5 will be instantly reclaimable. That's the common scenario that would break reclaiming.

Manik, I couldn't find "create new issue" link anymore on JIRA. Could you please point me to the entrance?

[Design of JBoss Web Services] - Re: Stack independent addressing implementation

by alessio.soldano＠jboss.com

Generally speaking I would see a common api living in jbossws-common. Then we should think about bridging from it to the underlaying stack implementation. Perhaps we could provide handlers doing the required conversions (to read/write the right objects in the MessageContext) and ask users to install them if they want to use the common api?

[Design of JBoss Web Services] - Stack independent addressing implementation

by alessio.soldano＠jboss.com

This thread is about https://jira.jboss.org/jira/browse/JBWS-2106[/url] and [url]https://jira.jboss.org/jira/browse/JBWS-2102. Since the JAX-WSA spec is in withdrawn state, there's actually no spec mandating how the ws-addressing advanced headers have to be set and retrieved. JBossWS Native provides his own implementation in the jaxws-ext module; JBossWS-CXF has its own too (and uses package org.apache.cxf.ws.addressing), JBossWS-Metro doesn't support anything besides what's in the jaxws 2.1 spec. A common way of setting the ws-a properties in the message and retrieving them would be useful, see the usecases Andrew wrote in the two jira issues above. Any idea?

[Design of JBoss jBPM] - Re: Concurrency in jBPM4

by alex.guizar＠jboss.com

anonymous wrote : Unfortunately - based on my knowledge - only the Thread based JobExecutor handles the exclusive Flag but not the enterprise deployment JobListenerBean. It does, starting from version 3.3.0 / 3.2.4. An ExecuteJobsCommand is constructed with the exclusive job IDs and sent to the command queue. The command executor then executes the jobs serially.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: split-brain between live and backup node

by timfox

In MessagingServerImpl: | private static class NoCacheConnectionLifeCycleListener implements ConnectionLifeCycleListener | { | private RemotingConnection conn; | | public void connectionCreated(final Connection connection) | { | } | | public void connectionDestroyed(final Object connectionID) | { | if (conn != null) | { | conn.destroy(); | } | } | | public void connectionException(final Object connectionID, final MessagingException me) | { | if (conn != null) | { | conn.fail(me); | } | } | } | You can see that when the connection is destroyed (closed as opposed to failed) then the failure handler won't be called, so the channel never knows its replicating channel is dead.

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: Journal Clean up / Compactor

by timfox

I don't understand the issue with "linked list" and I don't understand you're solution to it (you didn't provide enough detail). If I have three files F1, F2, F3 (A = add, D = delete) F1 contains: A1, A2 F2 contains: D1, D2, A3, A4 F3 contains: D3, D4 The current algorithm should delete all files. Are you saying it is not?

[Design of Messaging on JBoss (Messaging/JBoss)] - Re: split-brain between live and backup node

by timfox

When those replicating connections are closed, the handler in RemotingConnectionImpl: | private class ReplicatingConnectionFailureListener implements FailureListener | { | public boolean connectionFailed(final MessagingException me) | { | synchronized (RemotingConnectionImpl.this) | { | for (Channel channel : channels.values()) | { | channel.replicatingChannelDead(); | } | } | | return true; | } | } | Should be called. This tells the live channels there is no more replicating channel and they should continue without replicating. Is this being called? If not, then that's where you need to debug View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4208694#4208694 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4208694
