WebLogic Server 12c Certified with Java 7 for Production Use
WebLogic Server 12c (12.1.1) has been certified with JDK 7 for development usage since December and we have now completed JDK 7 certification for use with production systems. In doing so, we have updated the WebLogic Server 12c (12.1.1) distributions incorporating fixes associated with JDK 7 support as well as some bundled patches that address several issues that have been discovered since the initial release. These updated distributions are available for download from OTN and will be beneficial for all WebLogic Server 12c (12.1.1) users in general.
Updated Oracle WebLogic Server 18.104.22.168 distribution
Never one to miss a trick, Markus Eisele was one of the first to notice the WebLogic Server 12c update and post a blog about it.
Sources told me that as of Friday last week you have an updated version of WebLogic Server 12c on OTN.
Using WebLogic Server 12c with Java 7 - Video
To illustrate the use of Java 7 with WebLogic Server 12c, I put together a screen cam showing the creation of a domain using Java 7 and then build and deploy a simple web application that uses Java 7 syntax to show it working.
Ireland OUG Presentation: WebLogic for DBAs
Simon Haslam posted his slides from a presentation he gave Dublin on 21/3/12 at the OUG Ireland conference. In this presentation, he explains the core concepts and ideas behind WebLogic Server, walks through an installation and offers some tips and common gotcha's to avoid. Simon also covers some aspects of installing and use Enterprise Manager 12c.
Note: I usually install the JVM and use the generic .jar installer rather than using an installer bundled with a JVM.
Slightly Retro: Jeff West on Enterprise Architecure and REST
In this weeks flashback, we look at Jeff West's blog from early 2011 where he provides some thoughtful opinions on enterprise architecture and innovation, then jumps into his views on REST.
After I progressed in my career and did more team-leading and architecture type roles I was ‘educated’ on what it meant to have Asynchronous and Long-Running processes as part of your Enterprise Application architecture. If I had a synchronous process then I needed a thread available to service the request and then provide the response.
Starting Managed Servers without an Administration Server using Node Manager and WLST
Blogger weblogic-tips shows how to start a managed server without going through the Administration Server, using the Node Manager and WLST.
Connect WLST to a Node Manager by entering the nmConnect command.
Using WebLogic Server Singleton Services
WebLogic Server has supported the notion of a Singleton Service for a number of releases, in which WebLogic Server will maintain a single instance of a configured singleton service on one managed server within a cluster. This blog demonstrates how the singleton service can be accessed and used from applications deployed on the cluster.
