Hi I am practising TSPIT recovery where I have to recovery table that was dropped at 22-MAR-07 11:20 and I do fully automatic recovery but I get an error. Could somone please advise. Thanks

RMAN> run {
RECOVER TABLESPACE smm_data, smm_indx UNTIL TIME "TO_DATE('03/21/2007 11:20:00','MM/DD/YYYY HH24:MIS')"
sql 'alter tablespace smm_data, smm_indx online';

where smm_data is the TS where the table was and smm_indx is the TS for the indexes. The restore went fine and then export was done and Import terminated successfully with warnings.
then I got
host command complete

sql statement: alter tablespace SMM_DATA online

Removing automatic instance
shutting down automatic instance
target database instance not started
Automatic instance removed
