Understanding tbcheck -pe

*Sample Data* Disk Usage for Chunk 1 Start Length ---------------------------- ----- ------ stores.informix.customer 8066 8 stores.informix.orders 8074 16 stores.informix.customer 8090 8 - is the 'Length' measured in pages? - is each listing, an extent? - does this mean that table 'customer' has two extents of 8 pages each and table 'orders' has 1 extent of 16 pages? - is there any utility or other tbcheck switches that will tell me exactly how many extents each table has and what the size of the next extent will be? Thank you Aaron
