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?

Thanks indeed
