Importing Partitioned Tables

Import attempts to create a partitioned table with the same partition or subpartition names as the exported partitioned table, including names of the form SYS_Pnnn. If a table with the same name already exists, then Import processing depends on the value of the IGNORE parameter.

Unless SKIP_UNUSABLE_INDEXES=y,inserting the exported data into the target table fails if Import cannot update a nonpartitioned index or index partition that is marked Indexes Unusable or is otherwise not suitable.
