Look at the Alter Index index_name Rebuild tablespace_name;

command. Allows you to rebuild and move the indexes on-line. This is available in 8i. Not sure what release you are on.

We are using dictionary managed tablespacse and yes I know I should use locally managed, but I am not allowed to change.

I have significant fragmentation. I moved all my tables to a new tablespace, rebuild them properly so that they would not fragment(kept the Initial and Next extents the same) compacted them to PCTUSED 99 and PCTFREE 1(wont be any inserts,updates or deletes)

I coalesced the tablespace, but was unable to resize it. My indexes are fragmented too. Is there a simple command similiar to

ALTER TABLE MOVE in order to move my indexes to the new tablespace? What is the best method to move indexes to a new tablespace? Should I generate a script to rebuild them and then drop them?
