Weblogic Server Dynamic Cluster
Weblogic Server 12C 12.1.2 onwards Oracle introduced a new feature of clustering, called Dynamic Clustering. As clear from the name Dynamic, it’s a dynamic cluster where Managed Servers created dynamically at cluster creation time based on a cluster template and no of managed servers you specified during cluster creation. So, you don’t need to create Managed Servers separately, just mention how many managed servers you want with some basic configuration details like range of ports which you want to assign to managed servers, prefix for managed servers which will add at start of each managed server etc, and based on the standard template all managed servers will be created there. For any configuration changes you just have to change template configuration and it will be applicable for all clustered managed servers.
Another important use is, if anytime you think that you need one or more than one managed servers, just change the no of managed servers count configuration and it will create managed servers for you, you just go and restart newly created managed servers and it/they will start participating in cluster requests.
