Weblogic server in clustering


I cannot understand why  we should choose a managed server in the configuration of oracle weblogic server in clustering mode.
While in Oracle's definition, multiple application components are "clustered" by deploying them on multiple server instances in the cluster. So we should choose the cluster and not a particular server. O.O'?

Do you mean the remote run configuration -> 'Connect to' = 'cluster' -> 'Admin server name'?
In this case it is not a 'managed' server, but the 'management' server, which actually performs the management of the cluster.

I'm not sure what is your exact use case, if the answer is not relevant, please provide screenshot.

Thank you for your answer.

Yes I mean 'run configuration' --> 'Oracle weblogic server' --> 'connect to' --> {'Admin server' || 'Managed server'}

I want to understand the link between IntelliJ IDEA and Oracle weblogic.
I noticed that in Eclipse IDE you can target the admin server (for standalone mode)or the cluster (for clustering mode). But in IntelliJ IDEA, we choose between the admin server or one of the managed server. So why this difference? How to deploy properly on a cluster in IntelliJ IDEA?

Please clarify, do you use Local or Remote run configuration?
In case of Local you should see 'Server to launch' -> Admin || Managed,
in case of Remote you should see 'Connect to' -> Admin server || Managed server || Cluster

It is because with Local run configuration in IDEA you may start a single server instance, either admin or managed,
while with remote run configuration you don't start an instance and may choose a target to deploy - either a single server instance or a cluster.

So, if you want to deploy to a WebLogic cluser, you should first start a desired number of server instances, either with IDEA Local run configurations or
form outside of IDEA, then deploy to the cluster with IDEA Remote run configuration.
