Hi,
I am trying to create a cluster of weblogic instance running on different machines.I am not able to Properly configure..
I created machines , server , cluster ... but on startup it gives the error like NotOwnerException,ClusterException Not Found
I am also confused with Multicast Address.
I think BEA documentation is not Proper ...
i would really appreciate if u could send me the stepwise configuration ....
Thanks in Advance ..
Regards

if you create machines and server and cluster and deployed the server you created in the cluster you created you should be ok. as far as the multicast it is a network ipaddress to share all the clusters you created .. best of luck

Hi nand,
Step by step with the limitations of clustering:
- your cluster must be in LAN;
> I created machines , server ( I suppose that these are WLS server instances on separate phisical boxes);
- you have to have licence for clustering (I'm not sure if it works with 30-days demo version);
- if you are not using firewall it is OK, otherwise you have to bind servers to DNS;
- with using multicast they require you to use different dedicated multicast IP address: for servlet clustering and for object clustering;
- create machines;
- create WL server instances (use the same port for every instance; assign IP and machine name to each instance);
- create cluster with defining DNS(or IP) of each instance and multicast address;
- if you gonna replicate session state (servlets or session EJB) configure Replication Groups;
- homogeniously deploy web apps and ejbs; (be sure to mention about clustering in their deployment descriptors!!! For instance, for ejb you have to supply info into <entity-clustering> stanza - in that case you don't need explicetely generate replica-aware stubs -> ejbc will check supplied settings and automatically perform this task)
- start Admin server, then start all managed servers;
Thanks and good luck.

Nand,
Check first that you have a clustering license. The clustering license is NOT included in the 30-day download. If you're not sure, then you probably don't have one (expensive).
