Abstract: Methods, systems, and articles of manufacture are disclosed for facilitating database storage management. As disclosed herein, a computing system may determine a space availability for a segment included in a tablespace associated with a database. In one embodiment, the system may perform a vital statistics process that identifies a segment included in the tablespace and performs a dump process that collects segment information from a segment header included in the segment. Based on the dumped information, the vital statistics process may determine space availability information for the segment such as used space for the segment, fractional space used by the segment in relation to an amount of space of the tablespace, available free space for the segment, and/or a number of new rows that may be inserted into the segment.
