alter table shrink space compact/shrink space

Hi,

I am planning to run the following scripts to release space in a table that has been heavily cleaned up by 'delete ..' statement.

However, I wasn't sure if I should run

 "alter table .. shrink space compact' and then  "alter table .. shrink space '

or just use

 "alter table .. shrink space compact'

The database version we have now is 10g, but eventually, I will run the script on 11g database also.  I also wonder if I need to have concerns on indexes that  associated with the tables being 'shrink'.

Thank you!

Martin
