Moving a VM- 100 Ways to Skin a Cat

I love technology-   ALL TECHNOLOGY.  This includes loving my Mac Air and loving my Microsoft Surface Pro 4.  I’ve recently went back to a Mac when I joined Delphix, trimming down the power I had on my Surface Pro 4, knowing the content I was providing would be required to run on hardware with lesser resources.

VMWare, but I use Virtualbox!

A number of emails I received about trying out Delphix Express was regarding VMWare.  Many of my followers had used Virtualbox for a long time and we all know, no one likes change, (OK, maybe me, but we know how abnormal I am anyway… :))

Delphix Express- Adding XE DSource

For those of you that downloaded and are starting to work with Delphix Express, (because you’re the cool kids… :)) You may have noticed that there is an Express Edition Oracle 11g database out there you could use as a Dsource, (source database for Delphix to clon

Tips and Tricks- Delphix Express

Delphix Express offers a virtual environment to work with all the cool features like data virtualization and data masking on just a workstation or even a laptop.  The product has an immense offering, so no matter how hard Kyle, Adam and the other folks worked on this labor of love, there’s bound to be some manual configurations that are required to ensure you get the most from the product.

Maximum manageable storage in VMware versions


Maximum manageable storage per VM by ESX version

  • 4.1: 32TB (vmdk) / 120TB (RDM)
  • 5.0: 60TB (vmdk) / 3.75PB (RDM)
  • 5.1: 60TB (vmdk) / 3.75PB (RDM)
  • 5.5: 3.63PB (vmdk) / 3.75PB (RDM)

Note that the 60TB limit for 5.0 and 5.1 requires Update 1. Without this the limit is 24TB.

Oracle Linux UEK3, Huge Pages and VMware

For those of you using Oracle Linux with UEK3, here are a couple of important blog posts that may have passed you by.

Thanks guys!



Building vmware-tools in your Oracle Linux UEK3 VM

This is a quick writeup of an oddity I found while trying to install the vmwareware tools in an Oracle Linux host with the UEK3 kernel enabled (which is by default).

This is what is encountered during the vmware tools installation dialog when running

Searching for a valid kernel header path...
The path "" is not a valid path to the 3.8.13-16.2.2.el6uek.x86_64 kernel 
Would you like to change it? [yes]

The building of vmware tools fail because the kernel headers can not be found: the installer doesn’t see the kernel headers, whilst you probably installed it (it’s the kernel-uek-devel package belonging to the running kernel).

WebLogic 11g, Forms, ADF, Oracle Linux and VMware

Following on from my recent batch of “what I’m doing at the moment” style posts, I just thought I would mention some of the infrastructure I’ve been installing and configuring recently…

We are still part way through a migration from Oracle Application Server to WebLogic 11g. There are many applications to migrate and test, fortunately not by me, but they fit into two main categories.

Tomcat, Oracle Linux and VMware

Following from yesterday’s post about Cloud Control 12cR3, Oracle Linux and VMware, I thought I would just mention something I put live yesterday evening.

We have a 3rd party Java-based application that runs on Tomcat 7 and Java 7 that until recently was running on RHEL5 on physical hardware. It runs against an Oracle database, but that is not housed on this server. This application is not that big, but it is *very* high profile as it is what we use to process our REF submissions. If you know anything about higher education in the UK, you’ll know that REF is a very big deal, especially as we are within a couple of months of the next submission.

Cloud Control 12cR3, Oracle Linux and VMware

I mentioned some time ago that I was pushing my current company to move much of their gear on to VMware, mostly because of poor resource utilization on many of the servers. That process is still under way.

One thing I wanted to mention specifically was our use of Cloud Control 12cR3. Up until recently, we were using physical kit for this. We had an 11.2 database on HP-UX, With HA provided by HP Service Guard. We had two management servers on physical kit running RHEL5 pointing at this Service Guard package to give us some resiliency in of the OMS. It worked, but it was over complicated and I was never really happy with it for a number of reasons:
