Reduce Oracle Database size
Posted on 2011-02-20
Dear Experts ,
I have oracle 9i database and 10g database in the company which is used for testing purpose. The Database Size is 42 GB and the company decided to remove 2 year old data and take the export and store it on the DVD and use this server for different purpose.
I have deleted almost 90 % of the data from almost 100 tables but the size of the database is not reduced. The Database size is still the same.
I know that oracle 9i does not reclaim the free space. As far as i know for oracle 10g we can use shrink space or shrink space compact
So i need to reduce the size to as less as possible. So what is the best way to do that ?
Please let me know to reduce the size of the database for both 9i and 10g database ?
