Re: What address space is using AUX slots?
The 30% rule is a performance rule, not a capacity rule: 1. you should have enough space to accommodate a large page-out burst, when I occurs. 2. you should not fill this space over 30% to keep good performance on your page-outs. Although I think this rule is more important in a constantly paging system and less important for a one time page-out burst.

The JSTOR view doesn't tell which AUX slots are Flash and which are page DS slots. It's the sum of both. To my surprise, I can't see any job using VIO AUX slots. My previous assumption was wrong, it seems. What are reasons for SRM/AUX to page out to DASD instead of Flash, when Flash usage is low (below 10%)? I guess, none,are there? So, my current assumption is that we have had some peak on storage usage some time back which caused massive page out to Flash which also caused migration from Flash to AUX.

Re: What address space is using AUX slots?
Hi Peter I added some functionailtiy to EasySMF to try to answer this sort of question. You need the SMF type 75 and type 30 (all subtypes) records. Select the RMF Paging Activity: Page Dataset Usage report, and select the system you are interested in. Click and drag on the chart to select the time range where the usage is increasing. Then select the Job Status: Job Status During Interval report. This has columns with the delta and maximum for various storage areas for each job from the type 30 records. Click the column headers to sort. The values are high water marks. You would be most interested in anything with a large delta (increase in storage usage) or anything with a large maximum that was complete during the time period i.e. caused other things to page out. Jobs/address spaces that Started during the time period might also be interesting. You can download a 30 day trial version from: http://www.smfreports.com/download.html If you try it I would be interested to know if anything shows up.

Re: What address space is using AUX slots?
This is a console command, use SDSF: /F ... Do you have access to the mainview ispf interface? Start it, select 'Z', select '1', enter 'JSTOR' and you will see the ASM Slot usage under the column Avg Slots, next to it are Avg Vio and Avg NVio. Put 'SO D' after command, put your cursor on the Avg Slots column, press Enter and the display will be sorted on Asm Slot usage Kees. -Original Message- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Peter Hunkeler Sent: 23 October, 2014 13:25 To: IBM-MAIN@LISTSERV.UA.EDU Subject: AW: Re: What address space is using AUX slots?

The JSTOR view doesn't tell which AUX slots are Flash and which are page DS slots. It's the sum of both. To my surprise, I can't see any job using VIO AUX slots. My previous assumption was wrong, it seems. What are reasons for SRM/AUX to page out to DASD instead of Flash, when Flash usage is low (below 10%)? I guess, none,are there? So, my current assumption is that we have had some peak on storage usage some time back which caused massive page out to Flash which also caused migration from Flash to AUX. Does this sound reasonable? --Peter Hunkeler -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
