I want to know, which way is the best practice for preparing and deploying new configuration for WLS-cluster environment. How can I plan a simultan deployment of ALL of nodes, with out single point of failure?
I get the Answer as followed:
When you deploy an application OR redeploy an application, the deployment is initiated from the Admin Server and it it initiated on all targets (managed servers in the cluster) at the same time based on targets (which is expected to be cluster).
We recommend that applications should be targeted to a cluster instead of individual servers whenever a cluster configuration is available.
So, as long as you target the application to the cluster, the admin server will initiate the deployment on all the servers in a cluster at the same type, so application is in sync on all servers.
Hope that answers your queries. If not, please let me know what exactly you mean by synchronization.
