![]() wls1-4, the Admin server will attempt to talk to the node manager to start the servers. When you log into the weblogic admin console and attempt to start one of your servers e.g. Just have 2 clusters, one with wls1-2 and one with wls3-4. 1 A few things: No, you don't necessarily have to use a nodemanager, but it will make your life easier. That said, for your use case I doubt you need those master servers as all. So you will want to name your master servers in such a way that they are the first alphanumerically in the cluster. 1,065 2 18 29 Have you enrolled the managed servers Also, to get started, the easiest is to use the Plain Text mode via SecureListenerfalse inside the NM config and at the Console change the Nodemanager from SSL to Plain as well. The first Managed Server for each group becomes the group leader for the other (up to) nine Managed Servers in the group." The second set of 10 Managed Servers (if applicable) becomes the second group, and so on until all Managed Servers in the cluster are organized into groups of 10 Managed Servers or less. The first 10 Managed Servers in the list (up to 10 Managed Servers) become the first unicast clustering group. For unicast clusters, WebLogic Server reads these Managed Server names and then sorts them into an ordered list by alphanumeric name. "Each of the Managed Servers in a WebLogic Server cluster has a name. Here is the pertinent info from the Oracle Docs: With regards to Unicast it is pretty easy to set up (we just leave all the default values alone). Without the nodemanager you will have to start each server individually using the startManagedWebLogic.sh script and if you need to bring servers up and down often it will be very annoying. The start script starts it but the stop script doesn't stop it. This works perfectly for six of the servers, but one of them will not stop when I run the script to stop it. I use WLST scripts to start and stop them. ![]() No, you don't necessarily have to use a nodemanager, but it will make your life easier. 1 I manage seven Weblogic servers for development and test.
