Plugins

18. WebLogic 12c Admin Console
• Comfortable and feature-rich graphical JMX
client
• All changes from console are done via JMX
• Sometimes scripting is preferred
-> WLST scripts can be recorded

19. DEMO
Admin Console

20. WebLogic Scripting Tool (WLST)
• Efficient and versatile. It can replace:
- Configuration wizard
- Template builder
- Command line deployment:
weblogic.Deployer
- Admin console
• Online / offline mode
Frank Munz / www.munzandmore.com / Oracle DevCast
Slide #20

21. WLST
MW_HOME/wlserver_12.1/common/bin
contains start script for WLST: wlst.sh
Or run command-line with WL_HOME set and
weblogic.jar in classpath:
java weblogic.WLST [Script.py]
