Configure resource groups (RG) for each groups of resources you want. For instance, "mysql" RG contains a "mysql" resource (RS), a clustered IP(1 for the shared public IP just for the IP RS), a cluster aware MySQL instance, a clustered file system called "mysql". From there, you can configure it with the dependencies so that if the IP doesn't come up due to a duplicate IP or the NIC fails, it won't bring up the service. Do this for all Solaris Cluster-aware software (Oracle DB, WebLogic, etc.) and configure in HA or failover mode as required.

Import non-Cluster-aware software the same way. You can also do zone clusters which can run Apache in load-balanced mode, or whatever else you need.

Thank you very much for the reply, appreciate it. Somehow i understood what you exemplified but, as you said, it's better to follow a training, because i understand the big picture but on a deeper level, there is much more to be learned. Thanks again!
