Dear listers,
I am a DB2 sysprog and our DB2 statistics report shows a high number of "Pagein
for read I/O" (+5000/ minute) , just a single peak and nearly nothing around
the interval , so maybe not accurate.
I am trying to correlate this with RMF data (The DB2 i am looking on is DB2I) .
On this report PAGEIN RATE is 4 for DB2IDBM1. Not a big number , right ?
But on the next RMF report , at the same period (05:25) . There 32% of frames
available but the UIC is "only" 37686 ??
Can you please explain me a bit on these figures ?
Thank you for your answers.
