Running segment advisor for all indexes for a user. Many indexes are reported as "Perform re-org on the object" however the recommendation script simply says "Perform Reorg;" and fails to run.
Oracle does not generate a usable script in this case. You can use DBMS_REDEFINITION wizard to rebuild the object. When the objects are a table and index owned by SYS, you should not attempt to rebuild it.
Waiting for fix in a future release of Toad for Oracle.
