Seema,

PCTINCREASE - always 0.

PCTFREE - for lookup (code) tables = 10 for others, I use 20. My theory is that lookup tables have little or no updates, so this value should be small. If you have a high-update tables (columns that are updated a 8lot* after the record was created, you may want a higher value here.

PCTUSED - for lookup (code) tables = 90, for others, I use 80. Again, for lookup tables with little or no updates, I fill the data blocks as high as possible. For other tables, I currently use 80 as a starting point.

You will get many opinions here - read the docs to determine what you think is best for you.

Hope this helps.
