"If the tablespace of a database has a table which contains multiple extents, it does not necessarily indicate that the database needs to be turned. However, if there are chained rows within the table, the performance can be impacted. Recognizing this would indicate that the database needs to be optimized using one of the two methods discussed earlier."
