What is the resultant affects on the segments and space utilization when running the
ALTER TABLE MOVE COMPRESS command.

The ALTER TABLE...MOVE statement enables you to relocate data of a non-partitioned table or of a partition of a partitioned table into a new segment, and optionally into a different tablespace for which you have quota. This statement also lets you modify any of the storage attributes of the table or partition, including those which cannot be modified using ALTER TABLE. You can also use the ALTER TABLE...MOVE statement with a COMPRESS clause to store the new segment using table compression.
