Dick, I'm trying to follow your line of thought, but I think I missed the path.
Objects may not have the same storage requirements, but what does that matter? The only way I can make sense of what you say is if trying to have all objects occupy a single extent, and there's not much point in that.

Thomas, With the exception of temp and rollback tablespaces I have not user locally managed tablespaces just because all objects must have the same sized extents. I do not see most tables sharing an equal need for storage and using dictionary management allows one to do that, at a cost I'll admit, but one that is much easier to swallow. Dick Goulet Senior Oracle DBA Oracle Certified 8i DBA -----Original Message----- Sent: Thursday, May 29, 2003 3:25 PM To: Multiple recipients of list ORACLE-L After reading the documents I've recommended using LOCAL, UNIFORM, AUTO as the options for tablespace management. Does anyone have any bad experiences with these? AUTOALLOCATE seems to come up with extents that are much smaller than I want and MANUAL segment management requires the use of FREELISTs (and I know that there are problems with freelists freeing up space correctly, especially in a parallel environment). I can't find any basis for making a decision between UNDO and ROLLBACK SEGMENTS. Does anyone have any experience or recommendations about UNDO usage? The database will be a materialize view replication of a transaction master that is being used for decision support and has a 15 minute update/refresh cycle. Basically, people can run queries against the snapshot without impacting the master. -- Please see the official ORACLE-L FAQ: http://www.orafaq.net -- Author: Thomas Day INET: [EMAIL PROTECTED] Fat City Network Services -- 858-538-5051 http://www.fatcity.com San Diego, California -- Mailing list and web hosting services --------------------------------------------------------------------- To REMOVE yourself from this mailing list, send an E-Mail message to: [EMAIL PROTECTED] (note EXACT spelling of 'ListGuru') and in the message BODY, include a line containing: UNSUB ORACLE-L (or the name of mailing list you want to be removed from).
