System address space CPU time
This chapter is centered around the system address space level CPU consumption. The statistics report shows each of the 4 core address spaces (MSTR, DBM1, DIST, and IRLM) broken down by TCB, SRB, and zIIP time. We consider how these numbers should compare to each other, and what the DBA or system’s programmer can do to affect these numbers.
