JMX TOOLS / CLIENTS Admin console, JConsole, WLST, RESTful Management Services, Jolokia.

WebLogic Admin Console

WebLogic Scripting Tool

WebLogic 12c RESTful Management Services

JConsole

Open Source JMX Shell, RESTful API, Monitoring Plugins

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


DEMO Admin Console

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

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]


DEMO WLST

WLST Quick Reference ls() ls('a') shows aIributes , 'c' child MBeans, 'o' operaCons cd() navigaCon domainConfig() change to domain configuraCon tree serverConfig() change to server config MBeans domainRuntime() change to domain runCme tree serverRuntime() change to server runCme MBeans custom() change to custom tree jndi() change to JNDI tree edit() change to writable edit tree startEdit() start an edit session, then use set('aIribute','value') save() persist changes activate() / undo() acCvate / undo changes configToScript() export domain configuraCon to WLST script find() find aIributes easeSyntax() switch off python syntax (do not use for scripCng!)

WebLogic 12c RESTful Management Service •  Enable from admin console •  Retrieves cluster, server, deployment and JDBC http://host:port/management/tenant-monitoring/servers?format=full

•  Built-in AJAX client for testing: http://host:port/management/ajaxtest.html


DEMO RESTful

Management Service

•  HTTP/JSON bridge for remote JMX access •  -> Avoids JVM overhead on client side •  Uses j4p.war or JVM agent on WebLogic •  Supports many JEE servers •  j4psh JMX shell with tab-completion and

syntax highlighting •  Understanding of MBean names required
