RE: Stop defragmenting and start ...

To shed a bit more light on the timing of the papers, here is the abstract from the second version:

ABSTRACT
Fragmentation is an issue of great concern to database administrators. Oracle has a multitude of commands, options, views, and statistics that address various aspects of fragmentation, but it is not obvious how these capabilities should be used on a day-to-day basis. There is also a great deal of partial information, obsolete information, and misinformation that has been published on this subject that can confuse and frustrate administrators. Most of this material was written before Oracle7 release 7.3 became available and commonly used. New functionality in Oracle7 release 7.3 reduces fragmentation issues and allows different techniques to be used that are both simpler and more effective. This paper describes Oracle's capabilities related to fragmentation and gives concrete and specific advise on how these capabilities should be applied.
This paper is targeted at an audience of experienced database administrators. It is based on Oracle7 release 7.3 and also covers new features introduced in Oracle8 version 8.0.

HTH,
Ruth

Thank you everyone. I figured the concept had been around a while before I heard of it, although I still remember the 'Eureka' moment when I stumbled across the paper several years ago.

I'm negotiating to get uniform LMT's implemented at my current gig, but converting the other dba's is more work than converting the objects. Today I'm working on document explaining this 'radical' new idea, and needed some evidence that it's been around for a while now.
