Degree of Parallelism in Stats

edited Apr 14, 2018 5:00AM in Database Tuning (MOSC) 2 commentsAnswered

I have a stats job where I have set degree = 7. However, when I execute the job it runs maximum parallel (30) across the 3-node RAC. Am I missing something that is overriding my specified degree?

These are the parameters I'm passing in the GATHER_TABLE_STATS job:

OwnName            => rec.owner

, TabName            => rec.table_name

, Granularity        => ''AUTO''

, Estimate_Percent   => DBMS_STATS.AUTO_SAMPLE_SIZE

, Degree             => 7

, Cascade            => TRUE

, No_Invalidate      => DBMS_STATS.AUTO_INVALIDATE)

On each instance the parallel_max_servers parameter is set to 10.

Thanks,

Howdy, Stranger!
