HANDS-ON #1: Storage Space Not Adequate
Your current database uses dictionary-managed tablespaces. In running
various performance-tuning scripts, you have discovered that one of
these tablespaces seems to have run out of space long before you
calculated that it would. In tracking activity in the tablespace, you
discover that the process of tables being created, then dropped and re-
created, with different storage settings, has been excessive. Give an
explanation for why your tablespace might have a problem, and list two
actions you can take to lessen the problem.
HANDS-ON #2: Data Blocks, Extents, Segments, and Tablespaces
In your own words, provide an explanation of the difference between a
data block, an extent, a segment, and a tablespace.
