Decrement would be more complicated, especially if there were work running on the supernumary ones.
I learnt "decrement is harder than increment" with PAGEDEL being later than PAGEADD. Also with DB2 Buffer Pool Dynamic sizing. I believe the slightly less than polite term is "evacuation". :-) Cheers, Martin Martin Packer, zChampion, Principal Systems Investigator, Worldwide Cloud & Systems Performance, IBM +44-7802-245-584 email: [email protected] Twitter / Facebook IDs: MartinPacker Blog: https://www.ibm.com/developerworks/mydeveloperworks/blogs/MartinPacker Podcast Series (With Marna Walle): https://developer.ibm.com/tv/category/mpt/ From: "Richards, Robert B." <[email protected]> To: [email protected] Date: 12/05/2016 12:21 Subject: Re: Dynamic CPU ADD to a z/OS lpar Sent by: IBM Mainframe Discussion List <[email protected]> Yes, I meet the requirements. :-) I found the logical processor add and proved it works as advertised. The only surprise was the lack of ability to decrement processors without a deactivate. Thanks for responding.

It would be "Logical Processor Add " under Operational Customization for the LPAR, but you need (digging back in memory now) z10 and z/OS 1.10. I assume you meet the requirements by now. :-) Best regards, Mark -- Mark Zelden - Zelden Consulting Services - z/OS, OS/390 and MVS ITIL v3 Foundation Certified mailto:[email protected] Mark's MVS Utilities: http://www.mzelden.com/mvsutil.html Systems Programming expert at http://search390.techtarget.com/ateExperts/ ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
