From report1 , we don't need to add more cf physical Link or subchannel From report2 and report 3, More cf physical Link or subchannel need be added.
I wonder whether we need add more cf physical Link or subchannel or not? Jason Cai From: Mark A. Brooks Date: 2017-11-22 23:02 To: IBM-MAIN Subject: Re: CF REPORT Subchannel activity (report 2) includes all (roughly 18 million) requests from the indicated source system to the CF, whereas structure activity (report 3) only includes the (roughly 8 million) requests targeted to the indicated structure. 12 million delayed out of all 18 million requests to the CF vs 7 million delayed out of 8 million for the one structure explains the difference for those two. I'm not familiar with the production of the CFSYS report. I suspect that the data samples used to produce it are not the same as the ones being used for the other two reports. I'm thinking the CFSYS time period is likely shorter than the 15 minute interval shown in the post-processor reports. Still, CFSYS indicates that roughly 50% of the 26K/sec async requests are being delayed, so 0.1% value seems low. But but there are other causes for delay (such as dump serialization) that could be factors.
