very sequential reads after apply PTF

Hi gurus,

I applyed the following patches at O.S. level

CUMPKG 7198

HIPER LVL 126

DB2 LVL 17

JAVA LVL 17

PTF MF41726

PTF MF42052

PTF MF42053

after this applyed, the cache optimizer was reset.

since this applyed the system have many sequential reads, and the performance is very low.

I check the ST04 and the data here is blank, I not activate the dbmon because i am affraid this cause problem in system performance (i have DB with 5 TB size).

I open a PMR at IBM, but them say the server is OK.

Any suggestions???

Best Regards,

Ernesto Castro.
