Re: not enough ITL slots for parallel DML operation

The only time this would be relevant is with parallel update/delete - in which case you have to be updating a partitioned table.

For this to take place, each PX slave addresses a single partition, so the question doesn't apply to the table partitions or the locally partitioned indexes. To cater for global, or globally partitioned indexes, a very special restriction comes in - the degree of parallelism is limited to the smallest value of INITRANS that Oracle finds on any of the relevant global/globally partitioned indexes - to address exactly the question that you have raised.
