Hello: One of the DIAGxx parameters addresses an optional change to the merging of DQEs in PVT after v1.9: do you specify this parm to use the new rules (I am quoting from INIT and TUNING)?
"VSM USEZOSV1R9RULES(NO|YES) "YES causes GETMAIN and STORAGE OBTAIN behavior to be unchanged from its historic behavior. NO causes GETMAIN and STORAGE OBTAIN behavior for user-region private area subpools that are both below and above the line to be implemented. Thus DQEs can be merged where possible. The default is YES to provide a seamless migration. However, IBM recommends that you specify USEZOSV1R9RULES(NO) to obtain a performance benefit for applications with long DQE/FQE chains for user-region private area subpools. The usage pattern of v/s could change due to the new rules, and if the v1.9 fit was snug, a small change in the usage pattern might set off a s878/80A/106 situation. regards, Joe D'Alessandro ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
