FRIDAY SPOTLIGHT: New VirtualBox 5.1 and Private Cloud Appliance Refresh

This week had been a busy one for us. We had several exciting announcements that we would like to inform you about.

Oracle VM VirtualBox 5.1

To enable organizations and developers to more easily and flexibly create and deploy on premises and cloud applications, we are pleased to announce the general availability of Oracle VM VirtualBox 5.1, the latest release of the world’s most popular free and open source, cross-platform virtualization software. The (more...)

Howto create a private 10 Gb network on an ODA X5-2

In my previous post Network considerations on an ODA X5-2 I described a solution where I created a private network to optimize network performance between the components running on an Oracle Database Appliance. I am talking about a Virtualized setup in this article, and rebuilding the second pair of public interfaces to become a private network bond, in order to get a faster connection between the virtual machines.

In this article I will describe the (more...)

Network considerations on an ODA X5-2

When you buy an Oracle Database Appliance (ODA) X5-2 off the shelve, you will get a machine with four times 10Gb copper Ethernet (bonded into two interfaces) for public communication and two 40Gb InfiniBand (bonded into one interface) for interconnect communication between the two ODA_BASE’s. You would think that should be more than enough. Well in most cases it is. The interconnect running through InfiniBand is stunning for RAC and the public interface should be (more...)

VirtualBox and Windows driver verifier

I was troubleshooting some Windows hangs on my Desktop system running Windows 8 and enabled driver verifier. Today when I tried to start VirtualBox it failed with this error message.

Failed to load VMMR0.r0 (VERR_LDR_MISMATCH_NATIVE)

Most of the online forums were asking to reinstall VirtualBox to fix the issue. But one of the thread mentioned that it was being caused by Windows Driver Verifier. I disabled it, restarted Windows and VirtualBox worked like a (more...)

PeopleSoft and Docker’s value proposition

If you haven't heard yet about Docker and/or container technologies, you will soon do. Docker has made one of the biggest impacts in the IT industry in 2014. Since the release of its 1.0 version on past June, it has captured the attention of many big IT vendors, including Google, Microsoft and Amazon. As far as I'm aware, Oracle has not announced any initiative with Docker, except for the Oracle Linux container. Still, Docker (more...)

Virtualbox: only 32bit guests possible even though virtualization enabled in BIOS / Intel Process Identification Utility shows opposite to BIOS virtualization setting

Virtualbox on my Windows 8.1 stopped running 64bit guests a while ago. I did not track down this problem. Now some months later i tried again and found some confusing things.

First setting:
BIOS virtualization enabled
Intel Processor Identification Utlility in 8.1: virtualization disabled

Second setting
BIOS virtualization disabled
Intel Processor Identification Utlility in 8.1: virtualization enabled
With both settings: Virtualbox runs 32bit guests but no 64bit guests.
 

After some searching, (more...)

Mounting VMWare-Volumes/Disks with Debian

Some time ago a vmware server did not recognize any more a data disk. This disk was formatted with vmfs v3 (enter the vmware server via ssh and type mount..). First thing i did, was creating an image of this disk, to play around without any danger of data loss.

There is a good article how to mount vmfs, but on debian i had to install the package otherosfs.

After i installed this (more...)

Join me at the next OTN Virtual Developer Day

    Hi All, On February 4, 2014 at 9:30 am PT I will be talking on the next OTN Virtual Developer Day about Oracle VM and Oracle Database. Come and discover the answers for the following questions: Does an Oracle Database perform well on a virtualized environment? What virtualization technology is more stable and […]

Problems when doing a V2V or P2V of a windows server to Oracle VM

Some time ago, I received the request to migrate some Windows 2008 Servers to my Oracle VM farm and after complete the P2V migration the newly create VM would not start. It would crash on boot with blue screen and error: STOP: 0x0000007B (0xXXXXXXXX,0xXXXXXXXX,0×00000000,0×00000000) This issue is related to the storage drivers needed for the guest […]

Joint Webinar with Oracle – Top 5 Key Reasons Why Oracle VM is Best for Oracle Database

My Presentation on Oracle Solaris Zones Capacity Management

So one more successful annual conference of All India Oracle Users Group (AIOUG) happened on November 9th and 10th at Hyderabad, India.

Earlier I used to attend Oracle database sessions at AIOUG but this time AIOUG board had done a remarkable job by extending the coverage to Solaris topics. Obviously as (more...)

Why use OVM for Oracle Databases

Some time ago I made a benchmark exercise to compare the performance of an Oracle Database running in a bare metal environment versus a virtualized environment to clear some of the main questions our team and clients in Revera have,

Playing with VirtualBox, Oracle 12c (12.1.0.1) and OEL 6.4 – Part 2

We will complete our lab by installing the Oracle Database software, create a Pluggable database and take a look in the Oracle Enterprise Manager Database Express. The steps to install and create an Oracle Database 12c are: 1 – Go

Using Virtualbox images with Hyper-V

In 2008 i wrote about using vmware images with virtualbox. To migrate a host from virutalbox to Hyper-V, you have to do nearly the same, but you have to convert the hdd:
C:\Users\schroff>"\Program Files\Oracle\VirtualBox\VBoxManage.exe" clonehd
"c:\Users\schroff\VirtualBox VMs\Debian64-DS\Debian64-DS. (more...)

Hyper-V: Compile Linux Kernel with Microsoft device drivers

After knowing, that running a linux inside Hyper-V is only working with the "legacy" network adapter (look here), i was trying to build a kernel with the drivers (Microsoft has added the drivers into the Linux kernel versions >2.6.32).
There is one nice tutorial out there:

Hyper-V: Installing a debian linux in a virtual machine – trouble with the (non legacy) network adapter

First try with a virtualization solution like Hyper-V is to install a guest. So let's try debian linux.
The installer runs through this points:
  1. Name & path of the virtual machine
  2. RAM
  3. Network (how to configure a virtual switch with internet connectivity or how to configure internet connectivity with (more...)

Hyper-V: Howto configure NAT for virtual machines

In my last posting i explained how to configure a vEthernet adapter to get connectivity to the internet. But there was one "problem": You had to provide one seperate IP for each virtual host, you want to connect to the internet.
But there is a solution (NAT) for this problem (more...)

Build an 11gR2 RAC cluster in VirtualBox in 1 Hour using OVM templates

[I originally posted this over at the Pythian blog. If you're not following it, you should! Way more content, by far smarter people than lil ol' me.]

After reviewing my blog post about running EBS OVM templates in VirtualBox, two of my teammates suggested that I work on something with potentially broader appeal. Their basic message was, "This is really cool for us EBS nerds, but what about the Core DBAs?"

So how does "11gR2 RAC in an hour" sound? :-) In this post, I'll demonstrate how to deploy the pre-built Oracle VM templates to create a two-node (more...)

Build an E-Business Suite 12.1.3 sandbox in VirtualBox with one hour of work

[I originally posted this over at the Pythian blog. If you're not following it, you should! Way more content, by far smarter people than lil ol' me.]

Self-directed learning about a product as complex as Oracle E-Business Suite can be challenging. Oracle helpfully provides a pre-built environment (called 'Vision') for training purposes. Configuring a viable training or "sandbox" environment on a workstation can be pretty daunting, however, considering:

  1. The memory and storage resources required to run a "small" Vision instance
  2. The need to install and configure the OS and a list of pre-requisite patches and packages
  3. Learning about the (more...)
