Both index range scan and fast full scan can be performed in parallel. For parallel fast full scan, parallelization is the same as for nonpartitioned index-organized tables. For a parallel index range scan on a partitioned index-organized table, the DOP is the minimum of the degree obtained from the previous priority list (such as in parallel fast full scan) and the number of partitions in the index-organized table. Depending on the DOP, each parallel execution server gets one or more partitions, each of which contains the primary key index segment and the associated overflow segment, if any.
