Oracle X5-2, from bare metal to VM Server. Without disks, without dvd drive.

Oracle offers a fine machine called the X5-2. Not to be confused with the ODA X5-2, which comes with sophisticated database software. The X5-2 is just bare metal.

The X5-2 is a 1HE 2 socket Intel machine with limited configuration options in terms of processor speed, number of cores and storage.

I will show you how to install Oracle VM Server software without even having a dvd drive for the installation disk, nor a hard (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.


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 […]

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 ( 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...)

Oracle Throws in the Towel on VMware Licensing – Reprise

Given the incredible number of comments I received on my last blog post, and the content of those comments, it is very obvious that folks are extremely confused by what I meant by that post, as well as the comments by Mr. Garsthagen (Oracle Director Level Employee), referenced in that post.

The confusion is typified by the following comment, the most recent I have received:

Oracle does not recognize either (Vmware/DRS Affinity) as a hard partition

First, to be completely clear, I have never stated, nor do I believe, that VMware (or any other software hypervisor for that matter) (more...)

Oracle Throws in the Towel on VMware Licensing

As all of my readers know, I have been a strong proponent of VMware virtualization of Oracle Database servers for license cost savings purposes. Predictably, Oracle has pushed back on this issue in the past. Well, they have now thrown in the towel.

In an online video, Richard Garsthagen, Director of Cloud Business Development EMEA for Oracle, has stated publicly that VMware host affinity rules (when combined with vMotion logging) work just fine, thank you very much, for purposes of establishing where Oracle software is "installed and/or running" for purposes of the Oracle Software License Agreement (OSLA).

Previously, (more...)
