You may want to see the following Oracle support paper on this issue:

OERR: ORA-19804 cannot reclaim %s bytes disk space from %s limit #288171.1

It offers five solutions and I think two of them are obvious enought that I can mention them. First look at what is in the flash recovery area and use rman to clean it up if necessary and two increase the size available to the flash recovery area. How do peform both these tasks is covered by the documentation.
