  In the last eight days the Oracle Technology Network Architect Day tour has stopped in Dallas, Anaheim (Disneyland, to be precise) , and at Oracle HQ in Redwood Shores,  CA. I was on-scene for the Dallas event, where I pulled a TMZ-style ambush on Chris Benedict from the Oracle Enterprise Solutions Group to capture this short video.     The other presenters escaped. But the slide decks from several of the presentations are now available on Slideshare:  IT Optimization: Reduce Data Center Costs and Set the Foundation for Future Growth as presented by Alan Levine, Oracle Enterprise Architect Senior Director Implementing Applications with SOA and Application Integration Architecture as presented by Vish Gaitonde, Director, Ecosystem Strategy, Application Integration Architecture Application Grid: Platform for Virtualization and Consolidation of Your Java Applications as presented by Sam Shah, Director, SOA and Integration, Oracle Enterprise Solutions Group Infrastructure Consolidation and Virtualization as presented by Steve Bennett, also a Director with the Oracle Enterprise Solutions Group Security in a Cloudy Architecture as presented by Geri Born, Security Specialist with the Oracle Enterprise Solutions Group I'll post more Architect Day presentations as soon as I track them down. A special thank you to Oracle ACE Directors Jordan Braunstein, Billy Tong, and Kai Yu, who were on hand in Dallas, and to fellow ACE Directors Basheer Khan and Floyd Teter for their participation in the Anaheim event.  (Floyd and his iPad came through again, allowing me to record the Anaheim panel discussion via Skype while sitting in my home office in Cleveland.) That audio, as well as audio from the panel discussion and a roundtable from the Dallas event, will be available soon as ArchBeat podcast programs. If you attended one of these events, a big thanks. Your active participation, your questions and input, are what these events are all about.  As new cities are added to the tour, we expect more of the same from the OTN architect community.

• Progress 4GL and DB to Oracle and cloud

  - by llaszews

  Getting from client/server based 4GLs and databases where the 4GL is tightly linked to the database to Oracle and the cloud is not easy. The least risky and expensive option (in the short term) is to use the Progress OpenEdge DataServer for Oracle: Progress OpenEdge DataServer This eliminates the need to have to migrate the Progress 4GL to Java/J2EE. The database can be migrated using SQLWays Ispirer: Ispirer SQLWays ProgressDB migrations tool The Progress 4GL can remain as is. In order to get the application on the cloud there are a few approaches: 1. VDI - Virtual Desktop is a way to put all of the users desktop in a centralized environment off the desktop. This is great in cases where it is just not one client/server application that the user needs access too. In many cases, users will utilize MS Access, MS Excel, Crystal Reports and other tools to get at the Progress DB and other centralized databases. Vmware's acquistion of Wanova shows how VDI is growing in usage. Citrix is the 800 pound gorilla in the VDI space with Citrix WinFrame (now called XenDesktop). Oracle offers a VDI solution that Oracle picked up when it acquired Sun. 2. Hypervisor Server Virtualization - Of course you can place applications written in client/server languages like Progress 4GL buy using server virtualization from Oracle, VMWare, Microsoft, Citrix and others. 3. Microsoft Remote Desktop Services (aka: Terminal Services Client) The entire idea is to eliminate all the client/server desktop devices and connections which require desktop software and database drivers. A solution to removing database drivers from the desktop is to use DataDirect SQLLink

• Virtual Networks in Oracle Solaris - Part 5

  - by user12616590

             A         long         time      ago in a    blogosphere   far, far away... I wrote four blog entries to describe the new network virtualization features that were in Solaris 11 Express: Part 1 introduced the concept of network virtualization and listed the basic virtual network elements. Part 2 expanded on the concepts and discussed the resource management features. Part 3 demonstrated the creation of some of these virtual network elements. Part 4 demonstrated the network resource controls. I had planned a final entry that added virtual routers to the list of virtual network elements, but Jeff McMeekin wrote a paper that discuses the same features. That paper is available at OTN. And this Jeff can't write any better than that Jeff... All of the features described in those blog entries and that paper are also available in Solaris 11. It is possible that some details have changed, but the vast majority of the content is unchanged.

• Slap the App on the VM for every private cloud solution! Really ?

  - by Anand Akela

  One of the key attractions of the general session "Managing Enterprise Private Cloud" at Oracle OpenWorld 2012 was an interactive role play depicting how to address some of the key challenges of planning, deploying and managing an enterprise private cloud. It was a face-off between Don DeVM, IT manager at a fictitious enterprise 'Vulcan' and Ed Muntz, the Enterprise Manager hero .   Don DeVM is really excited about the efficiency and cost savings from virtualization. The success he enjoyed from the infrastructure virtualization made him believe that for all cloud service delivery models ( database, testing or applications as-a-service ), he has a single solution - slap the app on the VM and here you go . However, Ed Muntz believes in delivering cloud services that allows the business units and enterprise users to manage the complete lifecycle of the cloud services they are providing, for example, setting up cloud, provisioning it to users through a self-service portal ,  managing and tuning the performance, monitoring and applying patches for database or applications. Watch the video of the face-off , see how Don and Ed address some of the key challenges of planning, deploying and managing an enterprise private cloud and be the judge ! ?

There's one particular virtualization enhancement that can make a big difference for a lot of people: support for brownfield Oracle VM Servers for SPARC. Brownfield refers to Oracle VM Servers for SPARC that were created outside of Ops Center. In older versions of Ops Center, you couldn't really do anything with them - Ops Center could only manage OVM Servers that it created. If you had OVM Servers outside of Ops Center, you'd have to recreate them if you wanted to manage them. In 12.2, though, this problem is cleared up. You can discover and manage OVM Servers for SPARC that you created outside of Ops Center, so long as the LDom Manager is running. When you discover the control domain, all of the logical domains are automatically discovered and managed and appear under the control domain in the Asset tree. If you want to use server pools and migrate the logical domains to a different Oracle VM Server for SPARC system, you'll need to move the metadata to a shared library and use shared Fibre Channel or iSCSI LUNs for the guest domain storage and add the server to a server pool. See the Oracle VM Server for SPARC chapter for more information.

• Install XP Mode with VirtualBox Using the VMLite Plugin

  - by Mysticgeek

  Would you like to run XP Mode, but prefer Sun’s VirtualBox for virtualization?  Thanks to the free VMLite plugin, you can quickly and easily run XP Mode in or alongside VirtualBox. Yesterday we showed you one method to install XP Mode in VirtualBox, unfortunately in that situation you lose XP’s activation, and it isn’t possible to reactivate it. Today we show you a tried and true method for running XP mode in VirtualBox and integrating it seamlessly with Windows 7. Note: You need to have Windows 7 Professional or above to use XP Mode in this manner. Install XP Mode Make sure you’re logged in with Administrator rights for the entire process. The first thing you’ll want to do is install XP Mode on your system (link below). You don’t need to install Windows Virtual PC. Go through and install XP Mode using the defaults. Install VirtualBox Next you’ll need to install VirtualBox 3.1.2 or higher if it isn’t installed already. If you have an older version of VirtualBox installed, make sure to update it. During setup you’re notified that your network connection will be reset. Check the box next to Always trust software from “Sun Microsystems, Inc.” then click Install.   Setup only takes a couple of minutes, and does not require a reboot…which is always nice. Install VMLite XP Mode Plugin The next thing we’ll need to install is the VMLite XP Mode Plugin. Again Installation is simple following the install wizard. During the install like with VirtualBox you’ll be asked to install the device software. After it’s installed go to the Start menu and run VMLite Wizard as Administrator. Select the location of the XP Mode Package which by default should be in C:\Program Files\Windows XP Mode. Accept the EULA…and notice that it’s meant for Windows 7 Professional, Enterprise, and Ultimate editions. Next, name the machine, choose the install folder, and type in a password. Select if you want Automatic Updates turned on or not. Wait while the process completes then click Finish.   The VMLite XP Mode will set up to run the first time. That is all there is to this section. You can run XP Mode from within the VMLite Workstation right away. XP Mode is fully activated already, and the Guest Additions are already installed, so there’s nothing else you need to do!  XP Mode is the whole way ready to use. Integration with VirtualBox Since we installed the VMLite Plugin, when you open VirtualBox you’ll see it listed as one of your machines and you can start it up from here.   Here we see VMLite XP Mode running in Sun VirtualBox. Integrate with Windows 7 To integrate it with Windows 7 click on Machine \ Seamless Mode…   Here you can see the XP menu and Taskbar will be placed on top of Windows 7. From here you can access what you need from XP Mode.   Here we see XP running on Virtual Box in Seamless Mode. We have the old XP WordPad sitting next to the new Windows 7 version of WordPad. This works so seamlessly you forget if your working in XP or Windows 7. In this example we have Windows Home Server Console running in Windows 7, while installing MSE from IE 6 in XP Mode. At the top of the screen you will still have access to the VMs controls.   You can click the button to exit Seamless Mode, or simply hit the right “CTRL+L” Conclusion This is a very slick way to run XP Mode in VirtualBox on any machine that doesn’t have Hardware Virtualization. This method also doesn’t lose the XP Mode activation and is actually extremely easy to set up. If you prefer VMware (like we do), Check out how to run XP Mode on machines without Hardware Virtualization capability, and also how to create an XP Mode for Vista and Windows 7 Home Premium.

• Linux-Containers — Part 1: Overview

  - by Lenz Grimmer

  "Containers" by Jean-Pierre Martineau (CC BY-NC-SA 2.0). Linux Containers (LXC) provide a means to isolate individual services or applications as well as of a complete Linux operating system from other services running on the same host. To accomplish this, each container gets its own directory structure, network devices, IP addresses and process table. The processes running in other containers or the host system are not visible from inside a container. Additionally, Linux Containers allow for fine granular control of resources like RAM, CPU or disk I/O. Generally speaking, Linux Containers use a completely different approach than "classicial" virtualization technologies like KVM or Xen (on which Oracle VM Server for x86 is based on). An application running inside a container will be executed directly on the operating system kernel of the host system, shielded from all other running processes in a sandbox-like environment. This allows a very direct and fair distribution of CPU and I/O-resources. Linux containers can offer the best possible performance and several possibilities for managing and sharing the resources available. Similar to Containers (or Zones) on Oracle Solaris or FreeBSD jails, the same kernel version runs on the host as well as in the containers; it is not possible to run different Linux kernel versions or other operating systems like Microsoft Windows or Oracle Solaris for x86 inside a container. However, it is possible to run different Linux distribution versions (e.g. Fedora Linux in a container on top of an Oracle Linux host), provided it supports the version of the Linux kernel that runs on the host. This approach has one caveat, though - if any of the containers causes a kernel crash, it will bring down all other containers (and the host system) as well. For example, Oracle's Unbreakable Enterprise Kernel Release 2 (2.6.39) is supported for both Oracle Linux 5 and 6. This makes it possible to run Oracle Linux 5 and 6 container instances on top of an Oracle Linux 6 system. Since Linux Containers are fully implemented on the OS level (the Linux kernel), they can be easily combined with other virtualization technologies. It's certainly possible to set up Linux containers within a virtualized Linux instance that runs inside Oracle VM Server for Oracle VM Virtualbox. Some use cases for Linux Containers include: Consolidation of multiple separate Linux systems on one server: instances of Linux systems that are not performance-critical or only see sporadic use (e.g. a fax or print server or intranet services) do not necessarily need a dedicated server for their operations. These can easily be consolidated to run inside containers on a single server, to preserve energy and rack space. Running multiple instances of an application in parallel, e.g. for different users or customers. Each user receives his "own" application instance, with a defined level of service/performance. This prevents that one user's application could hog the entire system and ensures, that each user only has access to his own data set. It also helps to save main memory — if multiple instances of a same process are running, the Linux kernel can share memory pages that are identical and unchanged across all application instances. This also applies to shared libraries that applications may use, they are generally held in memory once and mapped to multiple processes. Quickly creating sandbox environments for development and testing purposes: containers that have been created and configured once can be archived as templates and can be duplicated (cloned) instantly on demand. After finishing the activity, the clone can safely be discarded. This allows to provide repeatable software builds and test environments, because the system will always be reset to its initial state for each run. Linux Containers also boot significantly faster than "classic" virtual machines, which can save a lot of time when running frequent build or test runs on applications. Safe execution of an individual application: if an application running inside a container has been compromised because of a security vulnerability, the host system and other containers remain unaffected. The potential damage can be minimized, analyzed and resolved directly from the host system. Note: Linux Containers on Oracle Linux 6 with the Unbreakable Enterprise Kernel Release 2 (2.6.39) are still marked as Technology Preview - their use is only recommended for testing and evaluation purposes. The Open-Source project "Linux Containers" (LXC) is driving the development of the technology behind this, which is based on the "Control Groups" (CGroups) and "Name Spaces" functionality of the Linux kernel. Oracle is actively involved in the Linux Containers development and contributes patches to the upstream LXC code base. Control Groups provide means to manage and monitor the allocation of resources for individual processes or process groups. Among other things, you can restrict the maximum amount of memory, CPU cycles as well as the disk and network throughput (in MB/s or IOP/s) that are available for an application. Name Spaces help to isolate process groups from each other, e.g. the visibility of other running processes or the exclusive access to a network device. It's also possible to restrict a process group's access and visibility of the entire file system hierarchy (similar to a classic "chroot" environment). CGroups and Name Spaces provide the foundation on which Linux containers are based on, but they can actually be used independently as well. A more detailed description of how Linux Containers can be created and managed on Oracle Linux will be explained in the second part of this article.

• Profit's COLLABORATE 10 Session Selections

  - by Aaron Lazenby

  COLLABORATE 2010 is a mere 11 days away (thanks for the reminder @ocp_advisor). Every year I publish my a list of the sessions I think reflect some of the more interesting people/trends in enterprise IT. I should be at all of these sessions, so drop by for a chat--I'll be the guy tapping out emails on my iPad... Monday, April 19 9:15 a.m. - Keynote: Transforming Customer Value, Delivering Highest Customer Service Location: Keynote Hall I never miss Charles Phillips when he speaks--it's one of the best opportunities to get an update on Oracle product developments and strategy. And there's certainly occasion for an update: this will be Phillips' first big presentation since the Oracle + Sun Strategy Update in late January. Phillips is appearing with Oracle Executive Vice President of Development Thomas Kurian which means there should be some excellent information about how customers are using Oracle's complete software and hardware stack to address enterprise IT challenges. The session should provide some excellent context for the rest of the week's session...don't miss it. 10:45 a.m. - Oracle Fusion Applications: Functional Overview Location: South Seas FI met Basheer Khan at COLLABORATE 08 in Denver and have followed his work ever since. He's a former member of the OAUG Board of Directors, an Oracle ACE, and a charismatic enterprise IT expert. Having worked with the Oracle Usability Advisory Board, Basheer should have some fascinating insights to share about the features and interface of Oracle's Fusine Applications. This session, along with Nadia Bendjedou's "10 Things You Can Do Today to Prepare for the Next Generation Applications" (on Tuesday, April 20 8:00 a.m. in room 3662) should give attendees the update they need about Oracle's next-generation applications.   1:15p.m. - E-Business Suite in the Amazon Cloud Location: South Seas HI did my first full-fledged cloud computing coverage at last year's COLLABORATE show (check out my interview with Oracle's Bill Hodak), where I first learned about Amazon's EC2 offering. I've since talked with several people who have provisioned server space on Amazon's cloud with great results. So I'm looking forward to watching the audience configure an instance of the Oracle E-Business Suite release 12 on the cloud while Chuck Edwards from Blue Gecko drives. This session should take some of the mist and vapor out of the cloud conversation.2:30 p.m. - "Zero Sign-on" to EBS - Enabling 96000 Users to Login to EBS Without User Maintenance Location: South Seas HI'll be sitting tight in South Seas H for the next session on Monday where Doug Pepka, a ten-year veteran of communications giant Comcast, will be walking attendees through a massive single sign-on (SSO) project across the enterprise. I'm working on a story about SSO for the August issue of Profit, so this session has real practical value to me. Plus the proliferation of user account logins--both personal and professional--makes this a critical usability/change management issue for IT leaders planning for successful long-term IT implementations.   Tuesday 8:00 am  - Information Architecture for Men in Kilts Location: SURF AGetting to a 8:00 a.m. presentation is a tall order in Las Vegas, but presenter Billy Cripe will make it worth your effort. Not only is the title of this session great, but the content should appeal to any IT strategist looking to push the limits of Web 2.0 technologies in the enterprise. Cripe is a product management director of Enterprise 2.0 and Enterprise Content Management at Oracle, author of Reshaping Your Business with Web 2.0, and a prolific blogger--he knows how information architecture is critical to and enterprise 2.0 implementation.    10:30a.m. - Oracle Virtualization: From Desktop to Data Center Location: REEF FData center virtualization is still one of the best ways to reduce the cost of running enterprise IT. With the addition of Sun products, Oracle has the industry's most comprehensive virtualization portfolio. I must admit, I'm no expert in this subject. So I'm looking forward to Monica Kumar's presentation so I can get up to speed.   Wednesday 8:00 a.m. - The Art of the Steal Location: Mandalay Bay Ballroom JMany will know Frank Abagnale from Steven Spielberg's 2002 film "Catch Me if You Can." The one-time con man and international fugitive who swindled $2.5 million in forged checks went on to help U.S. federal officials investigate fraud cases. Now the CEO of Abagnale and Associates, he has become an invaluable source to the business world on the subject of fraud and fraud protection. With identity theft and digital fraud still on the rise, this session should be an entertaining, and sobering, education on the threats facing businesses and customers around the world. A great way to start Wednesday.1:00 p.m. - Google Wave: Will it replace e-mail as we know it today? Location: SURF EBy many assessments (my own included), Google Wave is a bit of an open collaboration failure. It may seem like an odd reason for me to be excited about this session, but I'm looking forward to the chance to revisit the technology. Also, this is a great case study in connecting free, available Internet tools to existing enterprise computing environments--an issue that IT strategists must contend with as workers spreads out and choose their own productivity tools.

• Availability Best Practices on Oracle VM Server for SPARC

  - by jsavit

  This is the first of a series of blog posts on configuring Oracle VM Server for SPARC (also called Logical Domains) for availability. This series will show how to how to plan for availability, improve serviceability, avoid single points of failure, and provide resiliency against hardware and software failures. Availability is a broad topic that has filled entire books, so these posts will focus on aspects specifically related to Oracle VM Server for SPARC. The goal is to improve Reliability, Availability and Serviceability (RAS): An article defining RAS can be found here. Oracle VM Server for SPARC Principles for Availability Let's state some guiding principles for availability that apply to Oracle VM Server for SPARC: Avoid Single Points Of Failure (SPOFs). Systems should be configured so a component failure does not result in a loss of application service. The general method to avoid SPOFs is to provide redundancy so service can continue without interruption if a component fails. For a critical application there may be multiple levels of redundancy so multiple failures can be tolerated. Oracle VM Server for SPARC makes it possible to configure systems that avoid SPOFs. Configure for availability at a level of resource and effort consistent with business needs. Effort and resource should be consistent with business requirements. Production has different availability requirements than test/development, so it's worth expending resources to provide higher availability. Even within the category of production there may be different levels of criticality, outage tolerances, recovery and repair time requirements. Keep in mind that a simple design may be more understandable and effective than a complex design that attempts to "do everything". Design for availability at the appropriate tier or level of the platform stack. Availability can be provided in the application, in the database, or in the virtualization, hardware and network layers they depend on - or using a combination of all of them. It may not be necessary to engineer resilient virtualization for stateless web applications applications where availability is provided by a network load balancer, or for enterprise applications like Oracle Real Application Clusters (RAC) and WebLogic that provide their own resiliency. It's (often) the same architecture whether virtual or not: For example, providing resiliency against a lost device path or failing disk media is done for the same reasons and may use the same design whether in a domain or not. It's (often) the same technique whether using domains or not: Many configuration steps are the same. For example, configuring IPMP or creating a redundant ZFS pool is pretty much the same within the guest whether you're in a guest domain or not. There are configuration steps and choices for provisioning the guest with the virtual network and disk devices, which we will discuss. Sometimes it is different using domains: There are new resources to configure. Most notable is the use of alternate service domains, which provides resiliency in case of a domain failure, and also permits improved serviceability via "rolling upgrades". This is an important differentiator between Oracle VM Server for SPARC and traditional virtual machine environments where all virtual I/O is provided by a monolithic infrastructure that itself is a SPOF. Alternate service domains are widely used to provide resiliency in production logical domains environments. Some things are done via logical domains commands, and some are done in the guest: For example, with Oracle VM Server for SPARC we provide multiple network connections to the guest, and then configure network resiliency in the guest via IP Multi Pathing (IPMP) - essentially the same as for non-virtual systems. On the other hand, we configure virtual disk availability in the virtualization layer, and the guest sees an already-resilient disk without being aware of the details. These blogs will discuss configuration details like this. Live migration is not "high availability" in the sense of "continuous availability": If the server is down, then you don't live migrate from it! (A cluster or VM restart elsewhere would be used). However, live migration can be part of the RAS (Reliability, Availability, Serviceability) picture by improving Serviceability - you can move running domains off of a box before planned service or maintenance. The blog Best Practices - Live Migration on Oracle VM Server for SPARC discusses this. Topics Here are some of the topics that will be covered: Network availability using IP Multipathing and aggregates Disk path availability using virtual disks defined with multipath groups ("mpgroup") Disk media resiliency configuring for redundant disks that can tolerate media loss Multiple service domains - this is probably the most significant item and the one most specific to Oracle VM Server for SPARC. It is very widely deployed in production environments as the means to provide network and disk availability, but it can be confusing. Subsequent articles will describe why and how to configure multiple service domains. Note, for the sake of precision: an I/O domain is any domain that has a physical I/O resource (such as a PCIe bus root complex). A service domain is a domain providing virtual device services to other domains; it is almost always an I/O domain too (so it can have something to serve). Resources Here are some important links; we'll be drawing on their content in the next several articles: Oracle VM Server for SPARC Documentation Maximizing Application Reliability and Availability with SPARC T5 Servers whitepaper by Gary Combs Maximizing Application Reliability and Availability with the SPARC M5-32 Server whitepaper by Gary Combs Summary Oracle VM Server for SPARC offers features that can be used to provide highly-available environments. This and the following blog entries will describe how to plan and deploy them.
