If Adaptive Server is configured for parallel create
index and chooses an enhanced parallel create
index query plan, showplan displays
information about the create index commands below
the PLL CREATE INDEX COORDINATOR
operator
and CREATE INDEX
operators.
For example:
create index i1 on t5(c1) with consumers = 3 . . .
