The APAR specifically mentions z/OS 1.7: "When running z/OS 1.7 on a System z9 D/T2094 the SRM invocation interval is incorrect, resulting in more timer interrupts than intended. This can lead to an increase in uncaptured time." (wonder why not R8 also?) but the flash says: "This circumvention should be applied to all versions of z/OS." So does it make a difference in R6 and below? Or is it really only apparent on R7 (and above?)? We're still at z/OS R6 and have been running z9s for about year. I don't look at capture ratio on a regular basis but our crack performance team <grin> does. I think they would have noticed a big change. Of course the flash does say YMMV.
