List, Is there a 'magic' number for num_rows that you use in order to set the parallel degree on tables and/or indexes?
We were told to use parallel degree of 4 for tables having more than 100,000 rows. Some of the on-line queries are running in parallel mode thus making batch jobs to go serial for lack of parallel slaves. Upon a closer look, we see tables/indexes having millions of rows having parallel degree set at 1 and tables/indexes having fewer than 100,000 rows are having parallel degree set at 4 etc., Is there a number for num_rows that you have been very successful to determine the parallel degree? Some of the indexes were re-built using parallel degree of 3 to reduce the 'create index' time but were not changed back to 'noparallel' recently and I need to answer these questions. TIA.
