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...

*Reposted with permission from Oracle’s Networking Blog and Neeraj Gupta While writing down this article, I will be referencing to Oracle's latest Engineered Systems which are built upon InfiniBand technology. Yes, I am talking about Exalogic, Exadata and SuperCluster platforms. In the smallest and minimalistic configuration, we have a set of hosts connected to a pair of InfiniBand switches in dual star topology. Why two ? To provide you with redundancy. Each host has one...

*Reposted with permission from Oracle’s Networking Blog and Neeraj Gupta Heard the buzz word - InfiniBand ? And wondering what it is ? Here is some information to get you started. I am quite sure that you are already familiar with more common networking technologies like Ethernet and various Wireless media these days. InfiniBand is yet another but it does not reach out to us in our daily lives as much as others and probably thats the reason you are still interested in reading...

Introduction In this previous post I showed how to use the TaskQueryService to query tasks. In this post, I am going to take this one step further and update the task payload and process the task. Main Article In order to do this, we need to use both the TaskQueryService and the TaskService. This introduces a couple of new challenges that we need to deal with. Let’s take a look at the basic outline of the code first, then drill into the challenges. First, we need to...
