clip_image002The WebLogic scripting and management features available with Coherence 12c Managed Servers make it easy to create Coherence clusters and manage applications. Using the Weblogic Scripting Tool (WLST),  the whole lifecycle of Managed Coherence Servers can be controlled, from creating and starting a Coherence cluster to deploying Coherence applications.

WLST scripts are written in Jython and can manipulate Weblogic JMX MBean’s to manage Weblogic and Coherence. The flexibility and power they provide make it easy to create, configure and startup up a complete Coherence environment – in just a few minutes.  This post will outline how to do just this, using some sample WLST scripts.

Installing Coherence

So lets get started. If you haven’t already done so you need to install the Java JDK 1.8 and zipped distribution of Weblogic – which also contains Coherence. You can find these here;

For the JDK installation just follow the instructions. To keep things really simple for the Cohernece installation we will be using the zip installer for Weblogic (and Coherence). This avoids the need to have Administrator rights on Windows etc. The directory you unzip Coherence into will be referred to as the MW_HOME.  Read the complete article here.
