create local index speed

edited Jun 20, 2017 2:20PM in Database Administration (MOSC) 10 commentsAnswered

11gR2 RDBMS enterprise edition, hash partitioned table, 8 partitions 124 million rows 7G.

When creating either a unique or non-unique index local index against this table using parallel I see that the parallel processes block each other.  I was finally able to create the index with one process, but i took 7.75 hours.  Any ideas as to how to speed the index creation?

Howdy, Stranger!
