Hi, Thanks to all those who replied. Just clearing the structure.
I have Hp LVM and the tables and indexes are on different tablespaces and different disks . Since the growth pattern has changed drastically , the no of extents have increased tremendously . Hence the need to rebuild the indexes . We plan to rebuild them into contiguous extents (only question being 1 extent or say 4-5 extents to take care of growth:--- 1 extent every 2 months ) Will the performance differ if they are on 1 extent or 5 extents ( both being contiguous) ? thanks shreepad -- Please see the official ORACLE-L FAQ: http://www.orafaq.com -- Author: INET: [EMAIL PROTECTED] Fat City Network Services -- (858) 538-5051 FAX: (858) 538-5051 San Diego, California -- Public Internet access / Mailing Lists -------------------------------------------------------------------- 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).
