<snip>
QQRYDEGREE - Query optimization degree set to *OPTIMIZE. This will give the maximum available resources to fullfil an SQL request through the SQL optimizer. This can have a significant Impanct upon system performance during this period, and is not recommended.
The recommended setting is *NONE, or *IO. This means the optimizer will tune the SQL request to the database, without consuming excessive amount of CPU. Use the QAQQINI file and CHGQRYA to fine tune, and set the query degree for business critical SQL requests.
