Camels and Rubber Duckies – Joel on Software

That was all I was going to publish. But then, what’s a blog post without a rant. So here’s more. A quote from Joel’s article:

In the world of software, you can just make a version of your product called “Professional” and another version called “Home” with some inconsequential differences, and hope that the corporate purchasers (again, the people who are not spending their own money) will be too embarassed at the thought of using “Windows XP Home Edition” at work and they’ll buy the Pro edition. Home Edition at work? Somehow that feels like coming to work in your pyjamas! Ick!

I run Oracle 10g XE on my laptop running Windows XP Home Edition. I don’t run any mission critical applications, but so far XE does what I ask it to do. However, from the minimum system requirements in the XE Installation guide :

One of the following 32-bit Windows operating systems:

  • Windows 2000 Service Pack 4 or later
  • Windows Server 2003
  • Windows XP Professional Service Pack 1 or later

If I hadn’t tried to run XE on the Home Edition, I would end up spendng an extra $119 on my next PC. Given that XE itself is “free to develop, deploy and distribute” it just doesn’t make sense to put money in the competitions pocket. I wish Oracle would just publish a list of XE features that cannot be used when running Windows XP Home.

Update

From the same XE installation guide mentioned above:

It is not possible to disable simple file sharing on Microsoft Windows XP Home. Oracle strongly recommends that you upgrade to one of the required operating systems identified in “System Requirements”. However, if you cannot upgrade, then Oracle recommends that you enable the firewall and ensure that port 1521 (or the Oracle listener port you configured during installation) is blocked. Note that blocking port 1521 blocks remote access to the database over TCP/IP.

To enable the firewall (or check that the firewall is enabled) on Microsoft Windows XP, see Microsoft Knowledge Base article number 283673, “How to turn on or turn off the firewall in Windows XP.”

So it seems the sytem requirements are not “minimum” system requirements and you can install XE on the XP Home Edition. The Professional Edition is recommended for security issues.
