Description : How are extents allocated to a segment? (for DBA)
Last Answer : Oracle8 and above rounds off extents to a multiple of 5 blocks when more than 5 blocks are requested. If one requests 16K or 2 blocks (assuming a 8K block size), Oracle doesn't round it up to 5 ... -block size. Oracle doesn't round it up to the multiple of 5 when a tablespace is locally managed.
