Symptoms

On DataPump Import you found that INDEX creation does not invoke parallel processes, even though PARALLEL > 1.

The issue can be reproduced at will with the following steps:

1. Create an DataPump Export dump file for a table that has many indexes.
2. Perform a DataPump Import and specify PARALLEL > 1
3. Monitor system processes to confirm no Data Pump Import Parallel processes are created.
