Problem with Name of Cluster

[manishgupta]

Hi all,
I am using JBoss3.0 and I have successfully clustered my two server instances running on two different machines. I have mentioned the following entries in cluster-service.xml.



DefaultPartition
true
UDP(mcast_addr=228.1.2.3;mcast_port=45566;bind_addr=192.168.0.30;ip_ttl=64;mcast_send_buf_size=150000;mcast_recv_buf_size=80000):PING(timeout=2000;num_initial_members=3):MERGE2(min_interval=5000;max_interval=10000):FD:VERIFY_SUSPECT(timeout=1500):pbcast.STABLE(desired_avg_gossip=20000):pbcast.NAKACK(gc_lag=50;retransmit_timeout=300,600,1200,2400,4800):UNICAST(timeout=5000):FRAG(down_thread=false;up_thread=false):pbcast.GMS(join_timeout=5000;join_retry_timeout=2000;shun=false;print_local_addr=true):pbcast.STATE_TRANSFER



Now my problem is that I want to set the change the name of cluster. But when I change DefaultCluster toi enything else. The JBoss gives me the following error on restarting.

16:34:18,406 INFO [MYDefaultPartition] Initializing

Please help me.

Thanks

Within the cluster-service.xml file there are a number of other services defined that refer to the DefaultPartition, if you are going to change the partition name you will also need to alter these to use the new partition name.

Also if you are running the all configuration of jboss you will also need to change the farm-service.xml file as this also refers to the DefaultPartition.

You'll need to change the name of the cluster in the session state
service as well, e.g. (name=YOURNAME)


jboss:service=DefaultPartition
<!-- Name of the partition to which the service is linked -->
YOURNAME
<!-- JNDI name under which the service is bound -->
/HASessionState/Default
<!-- Max delay before cleaning unreclaimed state.
Defaults to 30*60*1000 => 30 minutes -->
0

Thanks Bela,

I got it and now I can change the name of Clunster.

Thanks once again :-)
