Hi Raj,
Thanks, now I know than multiple groups of instance can reduce freelists =
contention for multiple instances accessing same table.

Dear Sinardy,
Freelist Groups is for Oracle Parallel Server or RAC.
It reduces contention on the segment header block, and reduce=20
inter-instance "pinging", at the cost of excessive disk space
consumption.
Please refere Oracle Concepts guide for more details.
Thanks and regards
Raj
