How can we reclaim(deallocate) unused space and shrink tablespace size (resize) when database is onl

Hello...

We are facing one problem that...

When we delete records.. though records are deleted but when we query for tablespace size with use of views dba_data_files and user_free_space,

we get same size of individual data files freed, currently allocated as before deleting records.

We want to do some process for application to get actual used and freed space of tablespace ?

So. my queries are

Application running 24 hours

Oracle database 11.1.0.6.0 standard edition and 11.2.0.1.0 xe

Whether any clause we can add in delete query, which frees the allocated space automatically we need not do any other operation?

Howdy, Stranger!
