Content theft on my blog

Posted by Martin Bach on August 18, 2010

I have received an email today from Don Burleson who informed me that a number of my articles have mysteriously appeared on another weblog hosted by wordpress on the name of http://gjilevski.wordpress.com/.  For instance:

My post: https://martincarstenbach.wordpress.com/2010/01/21/upgrade-clusterware-10-2-to-11-2/ has reappeared as http://gjilevski.wordpress.com/2009/11/24/upgrade-oracle-crs-10-2-to-oracle-grid-11-2/. Even the host names are identical! The next one is a bit better as he managed to remove my “the-playground.de” example with “gj.com”:

http://gjilevski.wordpress.com/2009/09/25/install-oracle-11-2-rac-deploying-dns-dhcp-for-gns/ is my https://martincarstenbach.wordpress.com/2009/10/02/build-your-own-11-2-rac-system-part-ii-dns-dhcp-for-gns/ but he forgot to add the corrections I made. I recognize my DNS server, auxOEL5 :)

The story goes on.

Copy: http://gjilevski.wordpress.com/2009/09/23/install-oracle-11-2-rac-using-dns-for-scan/ from original: https://martincarstenbach.wordpress.com/2009/09/26/build-your-own-11-2-rac-system-part-i-dns/

Copy: http://gjilevski.wordpress.com/2009/10/13/adding-node-in-oracle-11g-r2-grid-infrastructure. Original: https://martincarstenbach.wordpress.com/2009/10/12/build-your-own-rac-system-part-iv-extending-grid-infrastructure/

Copy: http://gjilevski.wordpress.com/2009/10/08/archivelog-retention-policy-in-rman-11g-r2/ Original: https://martincarstenbach.wordpress.com/2009/10/08/archivelog-retention-policy-changes-in-rman-11g/

And many more. It seems my blog is replicated almost 1:1 to his.

I am very disappointed to see that someone else has to resort to such extreme measures to boost his profile. Copyright aside, this is very unprofessional and I would have expected something else. If you are interested in the whole story, have a look at http://timurakhmadeev.wordpress.com/2010/06/02/content-thief/

Oh, and it’s not only me, more established authors such as Alex Gorbachev, Mark Bobak and Alex Fatkulin are also victims of this.

So, and that’s it from me about this matter.

Almost.

Having complained to WordPress and leaving comments on my articles they mysteriously disappeared overnight. Everyone affected should do the same, and I urge you to file complaints to wordpress to have the blog removed.

The renamdg command revisited-ASMLib

Posted by Martin Bach on August 15, 2010

I have already written about the renamedg command, but since then fell in love with ASMLib. The use of ASMLib introduces a few caveats you should be aware of.

USAGE NOTES

This document presents research I performed with ASM on a lab environment. It should be applicable to any environment, but you should NOT use this for production-the renamedg command still is buggy, and you should not mess with ASM disk headers in an important system such as production or staging/UAT. You set the importance here!  The recommended setup for cloning disk groups is to use a data guard physical standby database on a different storage array to create a real time copy of your production database on that array. Again, do not use you production array for this!

It has gone really quiet!

Posted by Martin Bach on August 4, 2010

Yes, it has, and I’m really sorry but at the moment all the blog writing has to take a lower priority. I am working very hard to finish my chapters of the upcoming  Pro Oracle Database 11g RAC on Linux, which turned out to be a lot more work than I expected. The last chapter I have to write from scratch is about ASM, and it’s again a meaty one. Luckily the first draft is complete and I sent it to Apress for review and the usual editorial work.

I so decided to quit my daytime job to focus entirely on the book, which I’d like to see released between Open World and the UKOUG conference this year.

Once completed, I intend to become a freelance Oracle database consultant, specialising on RAC (no surprises here!) and Oracle 11.2 upgrades. I am available from mid September (the first 4 weeks are already booked!) if you like-just contact me!
