Cloud Credibility challenges – blogging about my team members

So there is a fun website called “CloudCred” that allows individuals or teams to participate in various tasks and challenges –  everything from technical challenges to social and fun are covered and it is quite a good team building exercise, apart from the leaderboard challenge aspect!

One of the tasks is to blog about my team members and include links to their own blogs. We have quite a few team members so I can’t cover all of them, but here goes:

Of course this task is for our team – Xtravirt Limited, so we also have a company blog you can go and visit for some excellent content around the Cloud and Virtualisation industry.

Troubleshooting the Autolab vCloud Director 1.5.1 installation

I have had this issue twice now, where deploying vCD via the Autolab PXE boot option on the vCD VM fails. As far as I can tell, the process seems to fail on the Oracle Express DB installation, due to the RPM not being a valid package.  The vCloud Director steps seem to be the same for Autolab 1.0 or 1.1, so the following applies to both.

error: /root/oracle-xe-11.2.0-1.0.x86_64.rpm: not an rpm package (or package manifest)

You can see the error I was getting in the screenshot I captured during boot time below. I had checked the RPM file and everything else to ensure it was in place, and indeed it was. Even vCD installs via the script, although it of course does not work due to the database not being there.

 

 

Here is the process I used to correct my vCD install.

  • Allow VM to finish booting, even with the missing oracle DB.
  • Use PuTTy to SSH to the vCD VM (either direct from your VC or DC VM, or if you have the route setup, from your host machine (in the case you are using VMware Workstation for example). Default credentials are in the Autolab setup guide document
  • Open up the “Build” share on the NAS VM, and location the vcd-install script. Default location: \\192.168.199.7\Build\Automate\CentOS\vcd-install (open this with a text editor)
  • Locate the method for each section of the install script. There is a section for each process in the script. For each method, copy out the entire block, paste it into a new text document, and remove any exclamation marks from any “echo” parts of the script. I found that manually tracking through this script using PuTTy gave me issues with the exclamation marks being misinterpreted by the shell, so I removed these. You’ll need to get a script block for the following sections and do this:
    • verify() {}
    • installOracle() {}
    • configureOracle() {}
    • generateCertificates() {}
    • installvCD() {}
    • configurevCD() {}
  • Remember to copy the whole block, including the start and end braces {} – paste these into a new text document, remove the exclamation marks, then copy-paste them back into your shell open in PuTTy. Hit enter, and the method will be entered and ready for use.
  • Once all the methods have  been copied in, you can simply type the name of the method, followed by enter to execute them. By doing it this way, you can manually step through the process and figure out where any potential remaining issues may be. This script is normally executed during the PXE boot installation process so you don’t really get a chance to slowly track through it.
  • Type each method in until you reach and complete the last “configurevCD” one
    • verify
    • installOracle
    • configureOracle
    • generateCertificates
    • installvCD
    • configurevCD
  • You may find that the generateCertificates and installvCD methods complete and echo out that they had already been completed prior – this is fine.
  • After configurevCD finished, all being well, you should now have vCD started, and you should be able to browse over to https://vcd.lab.local and finish the initial configuration via the vCD web page.

 

Other tips to try would be to:

  • MD5 hash check the RPM of the Oracle Express database that you download and place in your Build share – make sure it is not a corrupted file
  • Ensure you have the correct version of vCD and the Oracle Express database downloaded

 

The latest trends in VMware and Cloud Computing

cloud computing

 

VMware promotes virtualization as a catalyst for cloud computing. Cloud infrastructures are built on and powered by VMware. VMware allows IT professionals to build solutions that are specifically tailored to a client’s individual needs. Internal and external clouds may be created to handle the needs of a growing business. Hybrid clouds are growing in popularity for businesses that want the convenience of both. Here are some of the benefits of VMware cloud virtualization:

 

  • Efficient Processes. VMware makes it possible to automate processes and employ utilization to increase IT performance. When IT professionals leverage existing resources and avoid expenses related to infrastructure investment, the total cost of ownership (TCO) is reduced tremendously.
  • Agility. End-users gain a more secure environment with cloud computing. With VMware, IT professionals can be assured that they will preserve IT authority, control and security while remaining compliant. Processes are also simplified to make the job easier. An IT organization is able to respond quickly to organizations with evolving business needs.
  • More Flexibility. IT professionals can use VMware in conjunction with traditional systems for maximum flexibility. The systems may be deployed internally or externally. When configuring VMware, IT professionals are not limited to using any one vendor or technology. The solutions are portable and are capable of using a common management and security framework.
  • Better Security. VMware solutions protect end-points, the network edge and applications through virtualization. The cloud based deployments of security patches and solutions are dynamic and constantly being updated.
  • Automation and Management. With VMware, a highly efficient, self-managing infrastructure can be created. Business rules and policies can be mapped to IT resources when the tools are virtually pooled.
  • Portable and Independent. Open standard VMware solutions provide more flexibility and reduce the dependence on a particular vendor. With this security model, applications are easily portable from internal datacenters to external service provider clouds. The applications are also dynamic, optimized and deployable on public clouds with VMware cloud application platforms.
  • Saves Time. A self-service cloud-based portal is capable of reducing time spent by deploying standardized solutions that have been pre-configured to operate off-the-shelf or out-of-the-box. This method promotes efficiency through automation and standardization. Tailored services are also popular and can be achieved with VMware solutions. IT can remain in compliance and preserve control over policies with VMware.
  • Virtual Pooling and Dynamic Resource Allocation. Virtual datacenters are created by pooling IT resources through abstraction. Logical storage building blocks, server units and network are integrated into the solution to power applications. This process is completed in accordance to regulations and business rules. User demand also plays a role in how these applications are deployed and hosted.

 

How Businesses are using VMware to transition to the Cloud

Dynamic businesses have a need for a robust and affordable IT solution. Most businesses use 70 percent of their resources focusing on maintenance of servers and applications in a traditional system. With only 30 percent of the IT budget left for innovation, companies cannot grow and provide the type of service and products its clients need and desire. IT management is searching for a better strategy, and VMware seems to be a viable solution.

VMware provides users with faster response times. Faster response times lead to lower costs over time. Self-managed virtual infrastructures are efficient and preferred by many businesses.

IT professionals can identify which cloud-based solution is best for your company. The choices typically consist of a public, private or hybrid solution. Many companies have successfully implemented these solutions.

VMware’s cloud infrastructure and management application is commonly known as vCloud Director.  This application will allow a company to transition to the cloud at their own pace. The application was introduced in 2011 to provide companies with greater flexibility and efficiency in the cloud.

VMware’s solution allows companies the ability to leverage their existing infrastructure. This saved business owners significant time and money. The savings could then be reinvested for innovation. VMware’s cost-effective solution provides an answer to the pre-existing solution of 70 percent spending on infrastructure maintenance.

NetApp has exceptional backup and recovery capabilities that are necessary for any company’s disaster recovery solution. Within minutes, VMware’s vCloud Director can recover data. The backup and recovery system is customizable, fast and accurate.

NetApp and VMware have a 24 hour per day and seven day per week global staff monitoring the applications and data stored in the cloud. This ensures the data is protected. Technical support constantly works with all parties to ensure issues are addressed promptly and efficiently. Additionally, VMware ensures that resources are available to meet service level agreements.

 

Consider How VMware Can Help Your Organization

VMware is a viable solution that can be beneficial in any organization. Consider VMware for your business and witness an increase in productivity, efficiency and mobility. VMware solutions are chosen frequently because they work.
