  • Weblogic Domain Logically related group of WebLogic Server resources. Domains include a special WebLogic Server instance called the Administration Server, which is the central point from which you configure and manage all resources in the domain. Usually, you configure a domain to include additional WebLogic Server instances called Managed Servers. You deploy Web applications onto the Managed Servers and use the Administration Server for configuration and management purposes only.
  • Slide 9
  • Weblogic Domain
  • Slide 10
  • Domain configuration Config 1: WebLogic Server installation to create and run multiple domains Config 2: Multiple installations to run a single domain
  • Slide 11
  • Domain configuration Config 1: WebLogic Server installation to create and run multiple domains Config 2: Multiple installations to run a single domain
  • Slide 12
  • Domain Configuration Which configuration to select? How you organize your WebLogic Server installations into domains depends on your business needs.

  • Jython JPython successor JPython = Java + Python Python written in Java Some facts freely available for both commercial and non-commercial distributed with source code Features Java can use Jython libraries To create scripts to add functionallity Jython can use Java classes (Interpreter used) Small code Python programs are typically 2-10X shorter than the equivalent Java program Why Jython? initially created in late 1997 to replace C with JavaCJava Jython
  • Slide 15
  • How WLST help? Provides a set of scripting commands that are specific to WebLogic Server You can extend the WebLogic scripting language to suit your needs by following the Jython language syntax.

  • How to execute WLST commands? Interactive Mode on the command line Script Mode In batches, supplied in a file Embedded Mode Embedded in Java code
  • Slide 21
  • Interactive Mode Enter a command and view the response at a command-line prompt useful for getting immediate feedback useful for learning the tool, prototyping command syntax, and verifying configuration options before building a script.
  • Slide 22
  • Script Mode Invoke a sequence of WLST commands without requiring your input Much like a shell script. = WLST commands in a text file with a.py file extension. E.g. filename.py. To run commands Jython commands are used. What can be achieved? Automate WebLogic Server configuration and application deployment Apply the same configuration settings, iteratively, across multiple nodes Most Programming concepts available: loops, flow control constructs, conditional statements Schedule scripts to run at various times Automate repetitive tasks and complex procedures.
  • Slide 23
  • Embedded Mode Run WLST commands and scripts from java code. All WLST commands and variables that you use in interactive and script mode can be run in embedded mode. Example: import weblogic.management.scripting.utils.WLSTInterpreter ; import org.python.util.InteractiveInterpreter; public class function{ InteractiveInterpreter interpreter = new WLSTInterpreter(); StringBuffer buffer = new StringBuffer(); buffer.append("connect('weblogic','weblogic')"); interpreter.exec(buffer.toString()); }

  • MBean Managed bean Java bean that provides a JMX interface JMX is the J2EE solution for monitoring and managing resources on a network JMX is a public specification and many vendors of commonly used monitoring products support it. Here can be used to configure, monitor, and manage WebLogic Server resources through JMX.

  • FAQs What about existing command-line utilities? It includes capabilities of following: weblogic.Admin->Used to interrogate MBeans and configure a WebLogic Server instance wlconfig Ant -> for making WebLogic Server configuration changes weblogic.Deployer utility for deploying applications. When would I choose to use WLST over the other command-line utilities or the Administration Console? Tasks can be done interchangeably But the method that you choose depends on whether you prefer using a graphical or command-line interface, and whether you can automate your tasks by using a script. WLST online vs offline? online -> connected to a running Administration Server or Managed Server instance offline -> not connected to a running server.
  • Slide 38
  • FAQs Can I run regular Jython scripts from within WLST? Yes scripting language can be extended following the Jython language syntax. Can I invoke WLST via Ant? Yes, one could fork a new weblogic.WLST process inside an Ant script and pass your script file as an argument. Can I customize WLST? Yes. You can update the WLST home directory to define custom WLST commands, WLST commands within a library, and WLST commands as a Jython module. For more information, see Customizing WLST.
