MEMORY report

PAGE TRANSFERS

 

READ

Number of 4-Kb pages read per second

WRITE

Number of 4-Kb pages written per second

Note

The sum of read and written pages does not match the IO’S PER SEC PAGE value of the ACTIVITY report. Memory management tries to group up to eight 4-Kb page-out pages (WRITE) for one input/output operation (SDV or START-SUCHANNEL). Each READ causes one 4-Kb page to be transferred, i.e. causes one input/output operation (SDV or START-SUBCHANNEL) (see also section “page fault” on page 451 of the glossary).

The READ and WRITE values do not include transfers from/to global storage, if any.
