Not to answer the question but to note you can see zHPF effectiveness in SMF 73 Channel Path Activity data.

Dear Listers, After having wade through the last 5 years worth of posts in this list where the word zHPF is mentioned I am now tending to my headache. And I still have no real answer to my questions... I am all but a storage administrator, let that be clear. - Are there any gotcha's in activating zHPF? - Does one activate zHPF one LPAR at a time or in a big bang for all LPARs in the sysplex? - Do I have to tell DB2 that zHPF has been activated for it to take advantage of it? We use DB2 and some sequential datasets, but no VSAM. CICS and IMS/DC as transaction monitors. Thanks and very best regards, Jantje. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN Unless otherwise stated above: IBM United Kingdom Limited Registered in England and Wales with number 741598 Registered office: PO Box 41, North Harbour, Portsmouth, Hants.
