Introduction In Fusion Applications, users are not directly assigned access to individual functions and data. Instead, access is provided through roles. Roles group users for a specific purpose and define their access privileges. During the provisioning and installation of Fusion Application, a Super User (FAADMIN, by default) is setup with the following roles, to administer the underlying technical stack (Fusion Middleware) and to act as a Functional Setup Manager....

Introduction There is a lot of confusion about how to use JSF component binding in managed beans in a clustered environment to meet high availability. In this post we will highlight important considerations. Main Article A very common mistake is to bind a JSF UI Component to a managed bean which is in a scope greater than requestScope or backingBeanScope. You should not do this for two reasons: UI Components are not serializable, so your application might fail to work...

Introduction Over a year ago I wrote a couple important posts about the domain architectures used in Oracle Identity Management deployments. You can find these posts here and here. These posts have been very popular. I’ve received lots of positive feedback on them but also a fair number of questions. So, I thought that it would be worth revisiting the topic now. Main Article Let’s Review My First Post So, the central premise of my first post was that it is a good idea to...

What is it? At the Oracle Open World 2011 conference, I presented a session titled "Enterprise-class SOA on Exalogic" along with Vikas Anand and Manas Deb. Exalogic is part of Oracle's new breed of engineered systems, and is geared towards the middleware space. For those new to the term, an 'engineered system' is one where a single vendor provides everything from hardware, network, OS, middleware, applications, etc in one appliance. The hardware and software are fully...

*Reposted with permission from Oracle’s Networking Blog and Neeraj Gupta I have been talking to many people who are working hard towards migrating an existing Ethernet based infrastructure or starting from grounds up to deploy their services and applications on InfiniBand based computing environments. At the end of the talk, it all looks very simple.. right ? But where to start.. that's the fun part. Lets give some insight into these type of discussions. Recall one of my...

*Reposted with permission from Oracle’s Networking Blog and Neeraj Gupta Quick Introduction to Linux Bonding As the name suggests, bonding driver creates a logical network interface by using multiple physical network interfaces underneath. There are various reasons to do so, including link aggregation for higher bandwidth, redundancy, high availability etc. Upper layers communicate through the logical bond interface which has an IP address but eventually the active physical...

*Reposted with permission from Oracle’s Networking Blog and Neeraj Gupta Virtualization is always a heavily talked subject among infrastructure owners. Someone may ask why ? Often times, at any given time, the capacity of hardware equipment used to deploy services may be more than the services can actually utilize them. Data center real estate and power is expensive. So, what do we want to do ? Consolidation. Hmm.. sure but what about security ? Someone will not like the fact...

Continuing from my last blog about InfiniBand building blocks, now lets review the network switches used inside Oracle's Engineered Systems a little bit in detail. This will help you in understanding the overall integration, network design, architecture and troubleshooting in later articles. There are total two category of network switches used to prepare computing environment inside the rack. InfiniBand Switches - two models used depending on requirements Sun Oracle 36-port...

With Dave Shaffer Introduction Recently, I had a discussion with several colleagues and one of our large customers about when to use BPMN and when to use BPEL to model business processes. I have discussed this topic before in this post but this conversation opened up an interesting new angle on the topic, which I wanted to share with you all. Main Article First of all, let me be clear about the scenario here. This is a large customer who is going to make extensive use of...
