Re: Extent allocation

Adrian,
 As Vladimir showed in the sql script using the ALTER TABLE ... ALLOCATE EXTENT... works great. I have tablespaces across multiple datafiles and of course they are not used up completely before a table's next will not fit in the free space of the datafile. You have to change the next extent size to fit the free space and then ALLOCATE the extend to the table before you do the dataload. You end up with datafiles used to the max and no wasted free space at the end of the datafile. The method described in the "round_robin.sql" is a method of loading different data loads into different datafiles.
Works great.
