How to use NodeManager to control WebLogic Servers by Zemian Deng

In my previous post, you have seen how we can start a WebLogic admin and multiple managed servers. One downside with that instruction is that those processes will start in foreground and the STDOUT are printed on terminal. If you intended to run these severs as background services, you might want to try the WebLogic node manager wlscontrol.sh tool. I will show you how you can get Node Manager started here.

The easiest way is still to create the domain directory with the admin server running temporary and then create all your servers through the /console application as described in last post. Once you have these created, then you may shut down all these processes and start it with Node Manager.

The first step above is to start and run your Node Manager. It is recommended you run this as full daemon service so even OS reboot can restart itself. But for this demo purpose, you can just run it and send to background. Using the Node Manager we can then start the admin in step 2, and then to start the managed server on step 3.

The NodeManager can start not only just the WebLogic server for you, but it can also monitor them and automatically restart them if they were terminated for any reasons. If you want to shutdown the server manually, you may use this command using Node Manager as well:

Developing Java EE applications with Maven and WebLogic 12c – Zemian Deng

The WebLogic Server 12c has very nice support for Maven now. The doc for this is kinda hidden though, so here is a direct link here.
To summarize the doc, Oracle did not provide a public Maven repository manager hosting for their server artifacts. However they do now provide a tool for you to create and populate your own. You can setup either your local repository (if you are working mostly on your own in a single computer), or you may deploy them into your own internal Maven repository manager such as Archiva or Nexus.
Here I would show how the local repository is done. First step is use a maven plugin provided by WLS to populate the repository. I am using a MacOSX for this demo and my WLS is installed in $HOME/apps/wls12120. If you are on Windows, you may install it under C:/apps/wls12120. Read the complete article here.
