ORA-03297 after PURGE and wanting to resize datafiles

Anyone running SOA 11g out there? Well, we just started working on a data
purge strategy (PS4) using the Looped Purge script supplied by Oracle.
Like others have written on the web, it doesn't delete everything so I put
together a "manual purge" script that deletes the data and then does a
SHRINK and DEALLOCATE UNUSED on various tables.

My question is this: We have purged about 90% of the data in our
tablespace and would now like to recover (shrink) the datafile(s) using:

ALTER DATABASE DATAFILE '+DG1/tstsoa/datafile/dev_soainfra.310.767790105'
RESIZE 5G;
commit;

But then receive this:

ERROR:
ORA-03297: file contains used data beyond requested RESIZE value


Is there now a way to "coalesce" the data stored in the datafile so it is
not fragmented?  Or, is my only option to create a new tablespace and move
all the Objects (tables and indexes) to the new - then rebuild (drop
datafiles) and resize the Original tablespace and move the Objects back?


Thanks,

Anthony
