Richard et al,

{for those who've been following the thread on Rebuilding Indexes ...}

I've just been reading the AskTom thread on rebuilding indexes at
http://asktom.oracle.com/pls/ask/f?p=4950:8:::::F4950_P8_DISPLAYID:6601312252730

and picked on the important line
"Coalesce... reclaim the free space from mostly empty index leaf blocks that will not be reused otherwise due to your increasing sequence. "

Richard has also pointed COALESCE as a better option. COALESCE would be a better option than REBUILD for Indexes on monotonically increasing sequences where older values are purged periodically.
