Hi all,
I need to migrate a queue and mdb into a cluster configuration.

from my MDB. I haven't any xml files, all is
and third question, why when I put myqueue-service.xml into
JBOSS_HOME/deploy-hasingleton/jms , why it doesn't hot deploy ??

Hi all,
I'm using Jboss AS 4.05GA and I was wondering how to contact the master node in
order to add new schedules on a ScheduleProvider.
I have 3 nodes in a Farm, and at one moment, there is only one node managing
Schedules
See my conf:
mbean
| MBeanServer server = MBeanServerLocator.locateJBoss();
| ClusterPartitionMBean cluster = (ClusterPartitionMBean)
MBeanProxyExt.create(ClusterPartitionMBean.class,
jboss:service=default_partition, server);
| VectorString nodes = cluster.getCurrentView();
|
some help will be appreciated ;)

You're the boss !
thks a lot, I can achieve it with R_R and your trick.
I will leave dummy key as I understand it is much better than other solution ,
for the cost of time.
thanks again.

no , what I want exactly is :
1) node 1 read /root/subroot/A
2) other nodes cannot read /root/subroot/A as node 1 is reading it (locked)
3) node 5 read /root/subroot/B
4) other nodes cannot read /root/subroot/B as node 5 is reading it (locked)
5) node 1 finishing reading (and writing
Well, I don't want any concurrency.
The fact is if one node of the farm is reading one node of the tree cache,
other node won't we allowed to read .
but with REPEATABLE_READ, all nodes can read cache.
if the first node read, override with same data, re - read, and I choose R_R,
will it lock
well I understand ur point of view.
I'm exactly use TreeCache (1.4.1 SP3 with Jboss 4.0.5GA) in this way :
put all my objects at /root/subroot , so I have :
| /root
| /subroot
| Integer1 : Object1
| Integer2 : Object2
| Integer3 : Object3
|
instead, I must have as
so, anybody has one solution for my use case ?

Hi all,
I use TreeCache (JbossCache 1.4.1 SP3 with Jboss 4.0.5GA) with a cache
configured in a clustered environnement.
I set in PESSIMISTIC/SERIALIZABLE mode and I want to lock only one node when I
read or write to it.
For example, if I have /root/subroot/A and /root/subroot/B, I read node A,
oups, don't care about READ_UNCOMMITTED in conf file, it is SERIALIZABLE I use.
