Project: Application Server 7
Issue Type: Bug
Components: Test Suite
Affects Versions: 7.1.2.Final (EAP)
Reporter: Ondrej Zizka
Assignee: Ivo Studensky
These tests fail intermintently on really slow machines.
To reproduce, try to run in EC2 on 32-bit "small" instance type.

-------------------------------
JBPAPP-8400 is fixed now. To keep the code in sync, we should apply the fix to AS as well.

> Please change present behavior.
> We need to define only one property -Dmcast (for ex., the name doesn't matter now) as command line parameter - this multicast address is needed to be distributed to every subsystem which manages any multicast communication. It is needed to be unique in every subsystem - JGroups, HornetQ etc. because we must avoid to interfere each other => port assignation must be unique for every a such component.
> This change is needed in both - IPV4 and IPv6...

[JBoss JIRA] (AS7-5472) datasource statistics

-------------------------------------
Summary: datasource statistics
Key: AS7-5472
URL: https://issues.jboss.org/browse/AS7-5472
Project: Application Server 7
Issue Type: Bug
Components: JCA, JMX
Affects Versions: 7.1.2.Final (EAP)
Reporter: Mathieu Lachance
Assignee: Jesper Pedersen
In the java visual vm, in the mbean tab, under the "jboss.as:subsystem=datasources,data-source=MyDataSource" mbean, attribute "statistics" is marked as "Unavailable"
When using the spy="true" attribute in the datasource subsystem in conjunction with the "org.jboss.jca" logger set as TRACE level in the logging subsystem, statistics are outputted as follow :
Statistics:
ActiveCount: 1
AvailableCount: 99
AverageBlockingTime: 0
AverageCreationTime: 248
CreatedCount: 1
DestroyedCount: 0
MaxCreationTime: 248
MaxUsedCount: 1
MaxWaitCount: 0
MaxWaitTime: 0
TimedOut: 0
TotalBlockingTime: 0
TotalCreationTime: 248
I would except to find those statistics available through separates jmx attributes when using the spy="true".

[JBoss JIRA] (JGRP-1405) TP: pool of hashmaps for message bundling
by Bela Ban (Created) (JIRA)
TP: pool of hashmaps for message bundling
-----------------------------------------
Key: JGRP-1405
URL: https://issues.jboss.org/browse/JGRP-1405
Project: JGroups
Issue Type: Enhancement
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 3.2
We currently have 2 message bundlers i TP: the default bundler which adds messages to a hashmap and, when full, has the sending thread serialize all queued messages into one and send it, and the transfer queue bundler, which has the sending thread place a message into a blocking queue and the dequeuer thread collect and send the bundled messages.
The disadvantage of the default bundler is that everyone has to wait adding messages to the hashmap, until message bundling has completed. OTOH, the transfer queue bundler blocks all sending threads when the blocking queue is full.
Let's create a third bundler, which behaves like the default bundler, but uses a *pool of hashmaps* rather than one. This way, when one hashmap is full, the other sending threads don't have to wait until bundling is complete, but can continue adding their messages to a different hashmap.

[JBoss JIRA] Created: (JGRP-931) Logical addresses: canonicalize UUIDs with IDs (shorts)
by Bela Ban (JIRA)
Logical addresses: canonicalize UUIDs with IDs (shorts)
-------------------------------------------------------
Key: JGRP-931
URL: https://jira.jboss.org/jira/browse/JGRP-931
Project: JGroups
Issue Type: Feature Request
Reporter: Bela Ban
Assignee: Bela Ban
Fix For: 2.9
Instead of using UUIDs as addresses, the cluster members should agree on shorts, e.g. 1 for A, 2 for B and so on, and use these instead of UUIDs.
This happens after a certain warmup time. E.g. the coord could assign these IDs, so they're unique.
IdAddress and UUID have to be able to do equals() or compareTo() with each other !
Advantage:
- we send a short (2 bytes) instead of a UUID (16 bytes)
- we use an IdAddress (class with a short) instead of a UUID. This is 6 bytes less per instance
- IdAddress might be faster with equals() and hashCode() than UUID
