Using Jboss as7.0.2.Final we have created cluster of four Node N1,N2,N3,N4.
Here N1 is master Node.
After creating cluster of (N1+N2+N3+N4) there is requirement to Unregister slave Node N2 from cluster.
Due to some restriction we are not able to use "Web Managment Interface".
Is there any way to Unregister Node N2 from cluster using "JBoss Application Server management API"?
If using "Comm
There is cluster of Five Node A1(Apache + mod_clusrer) for load balancing and N1 ,N2 ,N3 and N4 are Jboss As 7 .
Here N1 is master Node.

I am experiencing a strange Windows 2008R2 cluster related issue that is bothering me. I feel that I have come close as to what the issue is, but still don't fully understand what is happening.
I have a two node exchange 2007 cluster running on two 2008R2 servers.
Hello Experts,
Please help me with the exact steps on configuring two node cluster on RHEL 6.2,
I failed to configure the simplest cluster by below steps,
1- install RHEL 6.2 64-bit on both nodes
2- add to hosts file of each server ( 1 IP in local NW and another in IP private NW).
x.x.x.x node1-pub
z.z.z.z node2-pub
y.y.y.y node1-pvt
t.t.t.t node2-pvt
3- yum install ricci ( on both nodes )
I am working with a Sun StoredgeTek 6540 disk array connected to two Sun 490 servers. After taking one of the 490 nodes on the cluster down to single user mode I proceeded to install the latest cluster patch from Oracle. After the patch was completed the system rebooted, failed to rejoin the cluster, crashdumped and rebooted continuously.
I'd like to build a two or three node Pacemaker cluster that would manage Xen (or possibly KVM) virtual machines.
Is it possible to set up the Pacemaker cluster (or some of its components) in such a way that when all nodes are active the VMs will use all available RAM but when one node fails the cluster will reduce VM's memory to fit them all on remaining nodes?
We have just installed two Windows 2008R2 Enterprise machines with identical hardware. When running the cluster validation everything is ok.
We need to shut down MS Failover Cluster running on two nodes with MS Windows Server 2008 R2 Enterprise for hardware maintenance.
I recently came across two possible approaches on how to shut down the cluster:
First approach says to take the cluster resources offline and proceed to windows shutdown, on the other hand if you right-click on cluster name in FC snap-in under More Actions...
