Parallel processing access (PARALLELISM_MODE='C')
Db2 can use parallel processing for read-only queries.
- If the PARALLELISM_MODE value is:
- Db2 plans to use:
- C
- Parallel CP operations.
Non-null values in the ACCESS_DEGREE and JOIN_DEGREE columns indicate
the degree of parallelism that Db2 plans
to use. However, at execution time, Db2 might
not actually use parallelism, or use fewer operations in parallel
than originally planned.
