Re: how to release blocks of table?
Thanks Mladen and Lee I am always amazed by the ability and knowledge of the people on this list. You guys (all the list members) always come up with many options to do something so if some option does not work you have others.

Then the initial extent will be as specified when the original table was created. Some shops create large tables with a small initial extent for this reason: When they only want the schema structure in someplace else, they can get it without the big initial extents. You can also use emacs to directly modify the export file to change the storage parameters therein. Something similar to the following: Create the file fix-extents.el with the following: (beginning-of-buffer) (while (re-search-forward "INITIAL[ 0-9]*NEXT[ 0-9]*MINEXTENTS" nil t) (replace-match "INITIAL 1M NEXT 1M MINEXTENTS" nil nil)) (save-buffer) Run the following to fix the dump file test.dmp: emacs -batch test.dmp -l fix-extents.el -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: Stephen Lee 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).
