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.
Oleg
