Hello Rob,

Does the recommended setting for QQRYDEGREE vary based on your setting for QPFRADJ? For example, if your system is constantly adjusting memory pools doesn't that affect how your queries are optimized?
It depends. :-) According to
https://www.ibm.com/support/knowledgecenter/ssw_ibm_i_71/experience_web/adjuster.pdf adjusting is done every minute regularly. So, the adjustment will use some kind of average values for adjustment.
Therefore, on reasonably busy machines with a mostly even workload, I don't expect QPFRADJ to be great of a disturber.
