Today I had the pleasure to present about Oracle WebLogic Scripting Tool at the DOAG SIG Middleware, Cologne, Germany. First time for http://www.enpit-consulting.com. Slides are in german, but WLST scripts are still Jython, so also worth for the english Oracle Fusion Middleware Community ;)

RESTful Management Services in Oracle WebLogic Server 12c
Version: 12.1.1 (developer edition, ZIP, no installer)
Installation
unzip wls1211_dev as follows
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

INFO: Initiating Jersey application, version 'Jersey: 1.9 09/02/2011 11:17 AM'
(=> 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)
Login in as weblogic user and see the default HTML output
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
Add Accept Header with application/xml
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;)
See doc for details of all available RESTful-Services in WLS12.1.1 http://docs.oracle.com/cd/E24329_01/web.1211/e26722/toc.htm

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 )

My DOAG 2011 Slides – Upgrade Guide for Oracle ADF on WebLogic Server
Just translated my german slides from DOAG 2011 and uploaded those to slideshare.
Hopefully someone will find it useful. At the conference there were just too few attendees…

JDeveloper 11.1.2/WLS 10.3.5 hot deployment issue [solved]
Status: Solved
Applies to: JDeveloper 11.1.2 / WLS 10.3.5, Windows XP
Problem Description
Having activated the WebLogic Fast Swap Option
a strange Exception comes up in the Log-Window for the integrated WebLogic Server output.
java.net.URISyntaxException: Illegal character in opaque part at index 16: zip:C:/Dokumente und Einstellungen/ak/Anwendungsdaten/JDeveloper/system11.1.2.0.38.60.17/DefaultDomain/servers/DefaultServer/tmp/_WL_user/adf.oracle.domain.webapp/q433f9/WEB-INF/lib/adf-richclient-impl-11.jar!/oracle/adfinternal/view/faces/renderkit/rich/PageTemplateRenderer.class

at java.lang.ClassLoader.loadClass(ClassLoader.java:246)
Issue Analysis
It turns out that the Exception occures because the (by default) created WebLogic domain is located at a directory which contains spaces, e.g. C:/Dokumente und Einstellungen/<user>/Anwendungsdaten/JDeveloper/system11.1.2.0.38.60.17/
Solution
Move your JDev User Dir to a location without space in directory names! This can be done as follows
1. systemwide (for all your JDev installations)
2. or finegrained (for specific JDev installation)
$MW_HOME\jdeveloper\jdeveloper.exe -J-Dide.user.dir=c:\ak\JDeveloper
(this will not effect other jdeveloper installations on your machine.)
If you now start Jdeveloper a new jdev user dir will be created.
Note: If you want to keep your prefs, etc. copy the system11.1.2.0.38.60.17 from old location to the new one and delete the wls default domain
system11.1.2.0.38.60.17\DefaultDomain directory. (This is needed, because many scripts in DefaultDomain are generated at time of domain creation and so may contain absolute paths! So in order not to get stuck with those issues just delete the DefaultDomain directory. it will be created next time you start wls from jdeveloper)
Conclusion
After moving the jdev user dir you will see in the wls log window
(after Rebuild of your ViewController project).
Happy fast swapping! It is a real timesaver now!

Type error in Installation Guide for Oracle Team Productivity Center Server 11.1.1.3?!
Short post, but quite interesting to mention I think.
While going through the current installation guide of Oracle TPC Server 11.1.1.3 the following line catched my eyes:
“If you are using WebLogic Server as the installation server, make sure you are using version 10.3.4.”
That’s really up to date information;) IMHO WLS 10.3.3 is the “most current” WLS version.

Monitoring Dashboard in WLS Administration Console introduced
Type: Info
Applies to: Oracle WebLogic Server: 10.3.3
Just after JDeveloper 11.1.1.3 was released of course I had to give it a try;-) Somehow I am always curious about changes the Admin Console of the WLS. Since WLS is integrated it is really easy and quick to do. Just start a simple ADF Fusion Web app and open http://localhost:7101/console
The following things catched my eyes:
a) The Admin Console is internationalized. On my laptop the login form appears in german by default now: 
To change the language you just have to change the preferred language in the browser settings and reload the page.
b) On the Homepage I recognized a new entry: 
This opens the so called “Monitoring Dashboard” which obviously is developed by ADF Faces RC. Cool! No activation of the diagnostic console needed! No slowly loading Applet;) Thanks!
c) the diagnostic-console can still be activated in the preferences but just in order to inform that it has been replaced by the new monitoring dashboard….and the Request Performance
d) Request performance 
At the first look the view is a bit disappointing because you will not see anything here until you “…first configure WLDF instrumentation to use the ElapsedTimeAction diagnostic action attached to "Around" diagnostic monitors. Only data from the ElapsedTimeAction action is shown on this page.” See the context help for more information. (Maybe I will blog about it in more detail in a separate post)
It would be nice if this information (to first configure a WLDF inst) would be visible as INFO or WARNING directly on the Request Performance Tab.

TELDE - What's that?
If you are wondering what telde is all about then I would like to give a hint on a presentation my collegue Ulrich gave at DOAG 2009 : ADF 11g rich client development best practices . We are using TELDE for development, testing and so on...while developing Apps on the oracle stack (currently ADF11g/JDeveleloper/WebLogic/Oracle Enterprise Linux). So TELDE stands for
TEam Linux Development Environment
It consists of the following components right now:
Oracle Enterprise Linux 5.3
Oracle Database 11.1.0.7
Oracle WebLogic Server 11g
Oracle JDeveloper 11.1.1.xOracle Team Productivity Center
Hudson Continuous Integration Server
OpenLDAP
SVN Server
running on VMWare.
So if you are interested in setting up such an environment, look at http://padora.blogspot.com

WLS: Monitoring Oracle JRockit JVM with JRockit Mission Control remotely
Status: resolved
JRockit Mission Control: 3.1.2
WebLogic: 10.3.2
JRockit Mission Control: 3.1.2
WebLogic: 10.3.2
Use case
You have the need to remotely monitor and profile the JRockit JVM(s) of Oracle WebLogic Server.
Solution
- Install JRockit Mission Control on the client
- Configure WebLogic Server Domain with JRockit JVM
- Configure JRockit Management Server
Components/Products
| Product | Download | |
| Oracle® WebLogic Server | Download from OTN | |
| Oracle® JRockit Mission Control | Download from OTN |
How to
| Bereich | Beschreibung |
| | |
| Putty | Login as oracle on telde.local [oracle@telde ~]$ cd middleware/user_projects/domains/base_domain/ [oracle@telde base_domain]$ vi startWebLogic.sh |
| Putty/vi | Add the following java Options before starting the WLS instance: Save file and Close vi. |
| Putty | Start WLS [oracle@telde base_domain]$ ./startWebLogic.sh …. Notice the starting of the management server … [JRockit] Management server started on port 7091, ssl=false, authenticate=false. … |
| Client | Start JRockit Mission Control |
| JRMC | Create a new connection  Enter Host Enter Port  Click: Test connection => Status keeps “Unable to connect” Click: Finish Starting the console on the newly created connection you might receive the following exception: Could not open Management Console for telde.local. So how to fix? |
| Putty | Stop WLS |
| Edit startWebLogic.sh Add -Djava.rmi.server.hostname=<remotehost> to the java options so that it looks like | |
| Putty/vi | .. JAVA_OPTIONS="-Djava.rmi.server.hostname=telde.local -Xmanagement:ssl=false,authenticate=false,port=7091" ${DOMAIN_HOME}/bin/startWebLogic.sh $* Save file and exit vi. |
| Putty | Start WLS once again [oracle@telde base_domain]$ ./startWebLogic.sh |
| JRMC | Now try to test connection again. Result should be  |
| JRMC | Start the console and monitor CPU, Mem, seak for memory leaks, etc.  |
Resources
java.rmi.server.hostname (1.1 and later)
The value of this property represents the host name string that should be associated with remote stubs for locally created remote objects, in order to allow clients to invoke methods on the remote object. In 1.1.7 and later, the default value of this property is the IP address of the local host, in "dotted-quad" format.
