Re: Automatic or Uniform allocation
Ron, I agree, uniform sizing is best. I hardly ever use automatic except for small development databases and small MISC tablespaces and even then I think Why didn't I use use uniform 64K ? Cheers, Chris Quoting Ron Rogers [EMAIL PROTECTED]: Brad, For LMT's I prefer uniform sizing that I can define to meet the needs of the data. If you use automatic the extend sizes will change drimatically as the number if extends increase. With a little planning you can have little waste in the tablespace and use the tablespace for multiple tables of the same size requirements. We have used the partitioning and LMT's for the yearly data we have, about 5 gig per table per year and the extend count is only around 100 with minimal free space. It makes it easier in the planning stage if you can keep it simple. Ron [EMAIL PROTECTED] 01/22/2004 10:14:34 AM for LMTs... Advantages in uniform versus automatic?

RE: Automatic or Uniform allocation
We need to start moving these discussions to freelists per Jared's note. Brad - I agree with Ron. I think it is critical to read How to quit defragmenting . . . before making the change to ensure you clearly understand the concepts and receive the benefits. If someone on the list knows of a more recent paper, please post it. With uniform extents, you eliminate tablespace fragmentation, in addition to Ron's points. Dennis Williams DBA Lifetouch, Inc.

Re: Automatic or Uniform allocation
Jonathan: I'd go a bit further than that. Your article is fantasitic. I've read How to stop defrag ... several times. It just never clicked for me. I've been migrating to LMT using your article, and it's been great. It's crystal-clear, and I really appreciate the examples. Thanks!

Re: Automatic or Uniform allocation
Johnathan, Very interesting article. I especially like the parts where it is not our fault it is designed that way. I agree that with proper thought and trial, a lot of perceived performance issues can be eliminated or minimized. I could really use the compress option, I guess that I will have to upgrade to 9i. Darn, I only have 1 year under my belt on 8i and already 10g is in the pipe. Thanks for the article.
