Re: decrease initial extent
Thanks to all who replied. Alter table/index deallocate keep 64k worked like a charm. I did not checked it in depth but I think that it keep 64k from the actual end of the data, not the high water mark. When I read the manual about keep nk I was sure that it means above the high water mark. Yechiel Adar Mehish - Original Message - To: Multiple recipients of list ORACLE-L [EMAIL PROTECTED] Sent: Thursday, December 04, 2003 12:19 AM I don't understand. Here is what manual says: deallocate_unused_clause Use the deallocate_unused_clause to explicitly deallocate unused space at the end of the table, partition or subpartition, overflow data segment, LOB data segment, or LOB index and make the space available for other segments in the tablespace. It's not supposed to change the characteristics of the initial extent. Funny. I'll test it at home.

RE: decrease initial extent
Title: RE: decrease initial extent Mladen, Keep reading, it's further down. From the 8.1.7 SQL Reference Manual, under the ALTER TABLE entry (top of page 8-36): If you specify KEEP, then the specified amount of space is kept and the remaining space is freed. When the remaining number of extents is less than MINEXTENTS, then MINEXTENTS is adjusted to the new number of extents. If the initial extent becomes smaller than INITIAL, then INITIAL is adjusted to the new size.

You can move it after you convert the long field to LOB. As it is one of the system tables which appears in noexp$, it's not guaranteed that your database will work afterward.

Yechiel, I thought that the mantra of oracle sales people was disks are cheap, which i very correct, especially when they don't pay for the disks from their own pockets. What is measly 130M today?

Re: decrease initial extent
For tables/indexes, the minimum initial extent size is 2 blocks (8k = 2* 4k). Block 0 contains the segment header, block 1 contains the data/index entries.
