RESTful Management Services in Oracle WebLogic Server 12c

Version: 12.1.1 (developer edition, ZIP, no installer)

Installation

unzip wls1211_dev as follows

0000@2713_0-41266a23103b2a19

In order to be able to work with this edition we have to call configure.cmd. This basically unpacks all jars, create the registry.xml and wlserver\.product.properties

To have some reusable snippets I have created additional scripts in the new MW_HOME

env_wls12c_dev.cmd

@echo off
@rem ***************************************************************************
@rem This script is used to set the environment for
@rem Oracle WebLogic Server 12.1.1 dev ZIP edition
@rem ***************************************************************************

set MW_HOME=C:\oracle\product\12.1.1\middleware
set JAVA_HOME=C:\oracle\product\11.1.2.1\middleware\jdk160_24
set JAVA_VENDOR=Sun


install_wls12c_dev.cmd



@echo off
@rem ***************************************************************************
@rem This script is used to install Oracle WebLogic Server 12.1.1 dev ZIP edition
@rem ***************************************************************************

call env_wls1211_dev.cmd

title Installing WLS 12.1.1.0...

call %MW_HOME%\configure.cmd

pause


Now execute install_wls12c_dev.cmd



In order to create a domain by configuration wizard



a) call env_wls12c_dev.cmd



b) %MW_HOME%\wlserver\common\bin\config.cmd



RESTful Management Service API



Sounds cool...lets try



Activate by Domain > Configuration > Advanced Configuation > Enable RESTful Management Services



=> (restart required)



After restart you will notice the following in the output

(=> This is good news! It states that some RESTful service will be available.)



After Restart open http://localhost:7001/management/tenant-monitoring/servers



(the authorized users must be in the group Administrators or Monitors)



0001@2713_2713-41266a27ed555555



Login in as weblogic user and see the default HTML output



0002@2713_2713-41266a27efb11d34



If you e.g. need better proccessable formats, JSON and XML are of course also supported. Let's see how it is done and what it looks.



Add Accept Header with application/json



0004@2713_2713-41266a27f2c474d0



Add Accept Header with application/xml



0005@2713_2713-41266a27f36b5493



Currently there is REST support for Servers (all in a domain or specific one), Clusters ( all in a domain or specific incl server members), applications (all in a domain or specific app), data sources (all in a domain or specific).



With these capabilities it' possible to implement a custom monitoring solution. A slim mobile wls monitoring app (and more)! => Hands on;)

Dislikes



- Still many BEA* stuff in diffrent scripts. It would be nice to have a clean and straight product without any historical garbage.



- configure.xml : ProgramGroupName=BEA WebLogic Platform 10.3 (Integrated Build)....


Why there is still the need to have a programm group called "BEA WebLogic Platform 10.3"?


My suggestions: Oracle WebLogic Platform 12.1.1 or Oracle Fusion Middleware Platform 12.1.1, everythin else, but not 10.3!



Like



- Java EE 6 Support. (It took a long time..)


- Better Maven Support


- RESTful Management Service


- ZIP distribution. Although the file is called wls1211_dev.zip it is possible to create a domain in production mode by the configuration wizard. At least in a simple testdrive it worked for me.


-Startup time feels better than wls11g


- more to test...(-Dservertype=wlx  to avoid loading EJB, JMS, JCA )
