Hello,
Is there a simple way to release the table space after or while deleting the records? Truncate is not an option as we don�t want to take the table offline while truncating.

Thanks,
Vijay

also Truncate alleviates the need to issue COMPACT
command to reclaim and reuse storage.

this does not free any space that the deleted rows consumed. this frees space that was above the high water mark (never used). Any space that was once stored a row (used) will not be freed with this command.
