Shrink segment from em.
From EM, in Space Summary I saw some infomations such as:
Problem Tablespaces : 0
Segment Advisor Recommendations: 115
When go to the Segment Advisor Recommendations, there are many segments that Oracle recommend Shrink. I tried Shrink two segments with type INDEX. My tablespace that contains two this indexes, free space was increased. I wonder that rebuilding index is always NO (should not rebuilt index). So shrinking segment with type INDEX is good ???
