With as much mail that is going through, not sure if you got an answer for this one yet. I've had this happen to me in the past when someone created a partition for one of our tables that is recovered for our mart in the wrong tablespace in the primary system.
Do you have global indexes on this partitioned table? If so, you will need to pull the ddl for them, drop them, (yes, I know, it's painful, I wrote a whole post in my blog on this one titled "dumb dba trick #8006" due to the amount of pain...:)) then you'll be able to drop the partitions, recreate the index(es) and go from there to cleaning up afterwards.
Hope this helps!

Hi Tony,
Thanks
Tried that since sending the mail, but it complaints about being a composite partition and is unable to exchange partition.

Just a thought, how about exchanging the existing partitions with empty tables, then dropping and re-creating the partitioned table and exchange the tables with partitions again?
Cheers,

Hi,
I have the following issue
I have been asked to clone a subset of a very large database. Sofar nothing tricky and this works fine,
however...this database has a partitioned table with sub partitions spread over multiple tablespaces. some of which have not been cloned across as the requirement was the last few months worth of data.
RMAN clone command was succesful till the last bit where it tried to drop the tablespaces that were skipped. After that the database opened fine but subsequent selects on the table complain about missing datafiles (understandably) but I have no idea how to solve the problem.
I have tried offlining the tablespace (no error but does not solve the problem)
I have tried dropping the partition "ORA-14268: subpartition 'SYS_SUBP437' of the partition resides in offlined tablespace"
I have tried dropping the sub partitions but get error ORA14616 table not partitioned by List method"
I have tried offline the datafiles that are missing, but this does not solve the problem (mount and open mode).
I have tried offline drop the datafiles that are missing, but this does not solve the problem (mount and open mode).
I have tried to recreate the controlfile without the missing datafiles, no luck
Any other suggestions?
