WebLogic How-to Videos: Install, Upgrade, & Patch

Here is another great YouTube video by our product manager Monica Riccelli. She talks about installers now being standardized in Oracle for greater consistency -- no more WebLogic native installers. Also, JDK is no longer a part of the WebLogic install. The various installers she discusses include OUI, ZIP, OEPE, Coherence and more. Monica then takes us through a step by step install process.


After the install process is complete the video takes us through the configuration wizard. The ZIP installer is then discussed and its effectiveness, such as it being the smallest downloadable option, easy, and very popular with our customers and limitations (such as for development only and not to be used in production) highlighted. Monica then takes us through the configuration wizard, its usage, and when to use WLST scripts. The video then discusses NodeManager and its usage and discusses how to reconfigure a WebLogic domain on upgrade – through our GUI tools or through command line interface. Lastly, it highlights Opatch – a patch application tool used by our customers and standardized across all Oracle products. Really detailed video. Check it out!

Whitepaper: The Department of Defense (DoD) and Open Source Software

With tight budgets organizations throughout the U.S. Department of Defense (DoD) see the appeal of the open source model. Open source software (OSS) includes operating systems, applications, and programs in which the source code is published and made available to the public, enabling anyone to copy, modify and redistribute that code without paying royalties or fees. Open source “products” typically evolve through community cooperation among individual programmers as well as very large companies. An open source license permits anybody in the community to study, change and distribute the software for free and for any purpose.

At first glance it might seem that DoD organizations can avoid buying commercial software products simply by starting with open source software and developing their own applications. As this white paper shows, total cost of ownership (TCO) for open source software often exceeds that of commercial software. While minimizing capital expenses by acquiring “free” open source software is appealing, the up-front cost of any software endeavor represents only a small fraction of the total outlay over the lifecycle of ownership and usage. And while cost effectiveness is important, it must be carefully weighed against mission-effectiveness.

This paper seeks to answer two questions:

1. What are the tangible and intangible costs that the government should bear under an open source licensing model?

2. What are the tradeoffs and risks associated with open source licensing models in relation to commercially available software?

Download this whitepaper today to ensure you are considering the various cost drivers of owning and operating an application environment.

The WebLogic 12c Book is Finally Here

WebLogic 12c Distinctive Recipes for software architects, administrators and developers -- who know quite a bit about WebLogic, want to know more, but don’t want the typical ‘recipe book’ full of screenshots. This new book is a collection of best practice in administrating WebLogic, large-scale deployments,  performance-tuning biggest mistakes and tools, the JVM, using JMX with your own applications, stuck threads, JDBC myths, effectively detecting memory leaks, Java EE examples (deployments and NetBeans projects), Oracle Fusion Middleware (Service Bus, SOA Suite etc.) and WebLogic in the Cloud without the hype. The book provides insights you won’t find in the manual, like recommendations, discussions, best practices, deployable projects, webcast videos and directions on when to use a feature – and when not to. With all this and more, this book is the perfect complement to official courses and manuals. Check it out on Amazon.com.

How does EJIE, Basque Government's IT arm, uses Oracle WebLogic

Watch Mike Lehmann, Senior Director of Product Management from Oracle and Oscar Guadilla, Senior Architect from EJIE, Basque Government's IT Company, discuss EJIE's implementation of Oracle WebLogic Server. Hear EJIE's history with Oracle WebLogic Server, how and why they are using it for its web application platform, common services, file services, and intranet and the benefits they are gleaning. In addition, hear how EJIE is using WebLogic JMS for document management common service integration in its Eco-government project.

While you are at it, since you are at our youtube channel (www.youtube.com/oracleweblogic) already, take a look at the various 'how to' videos Jeff West, Steve Button and others from our product management team have published here. Topics such as WebLogic Maven Plugin, TopLink Grid, How to Patch a WebLogic domain and much more are covered. Great way to spend some of your downtime during the holidays! :)

A Pragmatic Path to Navigating your Infrastructure to the Cloud

If you’re like most IT managers, you’re probably struggling to meet new business demands using your traditional IT infrastructure. Recently, two featured industry experts from the analyst firm Gartner, Vice President and Distinguished Analyst Andy Butler and Vice President and Gartner Fellow Massimo Pezzini, discussed 'The Road to a Cloud-Enabled, Infinitely Elastic Application Infrastructure', the first event in a Webcast series focused on navigating your applications to the cloud.

Discussing the latest innovations in data center architecture, they touched upon cloud-based application platforms (CEAPs), fabric computing and integrated systems, highlighting rapid application configuration and deployment capabilities. “If we think of the workload demands that not just cloud applications but all virtualized applications place upon the hardware fabric, it simply becomes a very natural fit for people to look to a fabric-enabled, integrated system as the ideal vehicle to enable that kind of agility and that kind of very easy allocation of resources on the fly and only in such a way that people pay for what they actually consume”, added Andy Butler.

Discussing the interaction between private and public clouds, Massimo commented that it would be important for end users to have coherent environments in their public and the private cloud systems. For example, it would be very important to have the same development tools, the same deployment tools and the same monitoring tools available in a compatible fashion in both environments. It is quite important, Massimo added, to minimize the amount of skills needed and to have a homogeneous and consistent environment across the public and the private environment to fully implement this notion of hybrid computing. This can be done by utilizing standards that enable interoperability between the private and the public cloud environment.

The discussion also focused on Platform-as-a-Service platforms and the critical need for reliability, availability, scalability, security, performance, and throughput in these platforms, given that they need to support hundreds of thousands or even millions of users. Scalability is absolutely critical for supporting such a massive amount of users with possibly fluctuating workloads.
