reclaim tablespace

edited Jun 16, 2014 12:00PM in Database Administration (MOSC) 3 commentsAnswered

oracle 10.2.0.4

ISSUE: I have moved various tables and indexes from one tablespace to the other. it created lots of space on the original tablespace. many data files shows usage of 10% to 20%, meaning it is 80%-90% free but I can not shrink any of these data files.  Since these tablespace are 1 TB in size, it will not be feasible to move all objects to new tablespace, etc.

How would I regain most of the space by resizing each data files?

Howdy, Stranger!
