Jonathan, Folks A small change to include indexes too in the below Qs:- Qs Does conversion of freelist groups to 4 needs to be done ONLY for Tables & Indexes which undergo INSERTs & NOT for Tables / Indexes which undergo UPDATEs, SELECTs, DELETEs? NOTE Our Database Size is Huge i.e. 3 TB. Qs Any Other parameter that should also be changed when moving a NON-RAC Database to RAC? Thanks indeed for responding -----Original Message----- From: oracle-l-bounce@xxxxxxxxxxxxx [mailto:oracle-l-bounce@xxxxxxxxxxxxx] On Behalf Of Jonathan Lewis Sent: Wednesday, September 27, 2006 3:17 PM To: oracle-l@xxxxxxxxxxxxx Subject: Re: Altering Freelist Groups in 10gR2 ? The only option is to do the CTAS, as the freelist group blocks are located immediately after the segment header block in the first extent. The only other option to consider is 'alter table move' to move the table into a tablespace defined to use ASSM and forget about freelist groups - but I'm not very keen on ASSM for high-performance, high-concurrency systems myself.

Folks When converting a NON-RAC Database to RAC in 10.2, the freelist groups need to be altered to 4(= to the Number of RAC Nodes) How is the freelist groups to be altered? Seek to avoid usage of the CTAS command i.e. "Create Table <Duplicate Tbl Name with freelist groups 4> As Select * from Original Table" since this is very tedious Is there any performance issue/Others with using the alter approach versus the CTAS approach?
