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!

Reminder: WebLogic Global, Virtual Developer Day November 5

Just a quick reminder about the FREE virtual developer day focused on WebLogic (and Coherence) coming on November 5th.

This day, with content tailored for developers, will guide you through tooling updates and best practices around creating applications with WebLogic and Coherence as target platforms. We'll also explore advances in how you can manage your build, deploy and ongoing management processes to streamline your application's life cycle. And of course, we'll conclude with some hands-on labs that ensure this isn't all a bunch of made-up stuff - get your hands dirty in the code!

9am PT/12pm ET
REGISTER NOW


We're offering two tracks for your attendance, though of course you're free to attend any session you wish. The first will be for pure developers with sessions around developing for WebLogic with HTML5, processing live events with Coherence, and looking at development tooling. The second is for developers who are involved in the building and management processes as part of the application life cycle. These sessions focus on using Maven for builds, using Chef and Puppet for configuration and more.

We look forward to seeing you there - don't forget to invite a friend!

So what is Active GridLink for RAC?

I had referred to Active GridLink for RAC in my blog yesterday and since then got several questions on this topic. So I decided to re-visit Active GridLink. With the release of version 11g, Oracle WebLogic Server started to provide strong support for the Real Application Clusters (RAC) features in Oracle Database 11g, minimizing database access time while allowing transparent access to rich pooling management functions that maximizes both connection performance and availability. WebLogic is the only application server in the marketplace which has been fully integrated and certified with Oracle Database RAC 11g without losing any rich functionality. Active GridLink provides Fast Connection Failover (FCF), Runtime Connection Load-Balancing (RCLB), and RAC instance graceful shutdown. With the key foundation for providing deeper integration with Oracle RAC, this single data source implementation in Oracle WebLogic Server supports the full and unrestricted use of database services as the connection target for a data source.


For more details and to understand how our customer NEC leverages this capability, read the whitepapers on this topic.

Get in depth ‘how-to’ details from this youtube video from our resident expert, Frances Zhao.

Oracle WebLogic Server and Oracle Database: A Robust Infrastructure for your Applications

It has been said that a chain is as strong as its weakest link. Well, this is also true for your application infrastructure. Not only are the various components that constitute your infrastructure, like database and application server critical, the integration between these things [whether coming out of the box from your vendor or done in-house] is paramount. Imagine your database being down and your application server not knowing about it and as a result your application waiting indefinitely for a database response – not a great situation if high availability is critical to your application. Or one of your database nodes is very busy, but your application server doesn’t have the intelligence to decipher that – it keeps pinging the busy node when it can in fact get a response from another idle node much faster. This is what Oracle WebLogic and Database integration provides: Intelligent integration out of the box. Tight integration between Oracle WebLogic and Database makes your infrastructure robust enough that not only does each of your infrastructure component provide you with improved RASP [reliability availability, scalability, and performance] but these components work together to offer improved performance & availability, better resource sharing, inherent scalability, ease of configuration and automated management for your entire infrastructure. Oracle WebLogic Server is the only application server with this degree of integration to Oracle Database.

With Oracle WebLogic Server 11g, we introduced Active GridLink for Real Application Clusters (RAC). In conjunction with Oracle Database, this powerful software technology simplifies management, increases availability, and ensures fast connection failover with runtime connection, load balancing and affinity capabilities. With the release of Oracle Database 12c this summer, even tighter integration between Oracle WebLogic Server 12c (12.1.2) and Oracle Database 12c has been achieved and this further optimizes the integration for a global cloud environment.


Read about these capabilities in detail in the Oracle WebLogic-Database Integration Whitepaper. Get in depth ‘how-to’ details from this YouTube video on the topic from our resident expert, Monica Roccelli.

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.

Avocent's VP of Engineering: Leveraging WebLogic & More for DCIM Offering

Just prior to OpenWorld I wrote about our customer Emerson's Avocent division, the cutting edge work they are doing with their DCIM offering, and Steve Blackwell's sessions at OOW [Read the blog here]. We got lucky and were able to catch Steve live at OpenWorld for an OTN interview in which he offers further details on their Trellis platform, how it leverages Oracle WebLogic Suite, Oracle Coherence, Oracle Complex Event Processing, Oracle Service Bus and other Oracle technologies to offer a state-of-the-art platform for their customers.
