WebLogic Scripting Tool made Cool!
The document discusses the WebLogic Scripting Tool (WLST), which is based on Jython, a Java implementation of Python, highlighting its usage, features, and future developments. It covers how to extend WLST with Java APIs, manage configurations, deployments, and monitoring within WebLogic environments. Additionally, it notes upcoming changes in WebLogic Server 12c and the potential shift to RESTful management services.

- 24. Using WLST asJython module Why? • WLST uses Jython 2.2.1 (2007) • Current version of Jython is 2.7 (2015) • Jython 2.7 has many nice things, for example; – Package management: pip install logging – XML API’s: ElementTree – Easy multithreading: multiprocessing – Easy argument parsing: argparse

- 38. A look intothe future New WLST features in 12c • WLST 12c introduces Jline integration – use up and down arrows to browse command history • WebLogic Server 12c provides a Maven plugin to allow execution of WLST scripts in for example Continuous Delivery pipelines – https://docs.oracle.com/cd/E24329_01/web.1211/e24368/maven.htm#WLPRG700 • SOA Suite 12.2.1 instance patching only supported with WLST (not Ant or Maven) • WLST 12.2.1 offline mode does not support partitions (yet?) . WLST 12.2.1 online does support partitions (multitenancy)
- 39. A look intothe future However… • wlfullclient.jar is deprecated since 12.2.1 (related to multitenancy?) – http://docs.oracle.com/middleware/1221/wls/NOTES/whatsnew.htm#NOTES155 • RESTful Management Services replacing WLST in the cloud? – http://docs.oracle.com/middleware/1221/wls/NOTES/whatsnew.htm#NOTES353 • WLST has not seen a new Jython version since 11g

Editor's Notes
- #3 Recent awards: Oracle EMEA Middleware Partner of the Year, 3 times Oracle Netherlands Middleware partner of the year. One of the rare moments in the Netherlands when it isn’t raining.
- #8 In interactive mode, the shell managed a persistent connection to the server A script can be executed setWLSEnv.sh and “java weblogic.WLST <script>” or wlst.sh / wlst.cmd. java –cp wlfullclient.jar weblogic.WLST Embedded mode allows running WLST directly from Java using an Interpreter (weblogic.management.scripting.utils.WLSTInterpreter) http://www.qualogy.com/starting-wlst-scripts/ and http://www.slideshare.net/jambay/weblogic-scripting-tool-overview have useful suggestions
- #12 Configuration wizard uses this
- #26 Interactive and script are not called separate interaction patterns for nothing.
- #31 Notice differences between 11g, 12.1.3 and 12.2.1. 12.2.1 includes a single JAR which contains a manifest file containing the classpath (WLS_HOME\wlserver\modules\features\wlst.wls.classpath)
- #36 Different from executing directly from WLST!
- #39 Ant plugin at least in WLS 8.1. Not deprecated
