Re: Daylight Saving Time change
We have our z9 set to GMT/UCT. We code the necessary Timezone_definition and Timezone_boundary statements in SYSTEM CONFIG. You can code Timezone_boundary statements for many years ahead. We don't define anything in the VSE guests. On Sunday morning, we bring down all our VSE's, and VMs. We wait 1 hour to avoid any double timestamps in logs and files and databases. Then we restart everything. When VM is IPL'ed (and only then) it selects the correct timezone from SYSTEM CONFIG Timezone definitions. The VSE guests then automatically use the same timezone as VM. Depending on your setup you could keep VM running and issue a SET TIMEZONE command, but we think it's safer to just stop VM during 1 hour. It's also a good excuse to have the z9 for ourselves for a while and do all those changes that have been waiting to go into production...

Re: Daylight Saving Time change
Just a note that with Linux guests -- you don't need to worry about them... they'll adjust their clocks on their own. For other guests, you can recycle them after issuing SET TIMEZONE. VMUTIL can just be recycled -- since it's already done the events and noted them in VMUTIL SCHEDULE - it won't repeat them. Scott On Tue, Oct 13, 2009 at 7:35 AM, Frank M.

For VSE, what I learned: from the ASIPROC remove SET DATE remove SET ZONE remove SET ZONEDEF remove SET ZONEBDY Then VSE would take the definitions of the VM system under which it is running. You still need to reIPL the VSE guests when the timezone changes. For VMUTIL:no problems to expect. A bit simplified: a z Series has no timer to tell wake me up at hh:mm:ss; Wakeup allows hh:mm:ss.

Re: Daylight Saving Time change
Jim's process is solid. On the z/VSE web site there is a page that describes what needs to be done during the twice yearly time change (forward and backward). Of course, now I can't find it, apparently it's buried. In a nutshell, after the timezone is set in z/VM, z/VSE can get the new offset with the AR command TIME ZONE=VM. The CICS 'CEMT PERFORM RESET' commands will reset CICS's clock to the new OS time. Any other clock sensitive running jobs will need to be restarted as they will have the old clock setting. The one hour wait is only required in the fall, in the spring everything can continue as normal. An IPL is not required. I have customers that do not IPL for time changes and haven't for many, many years. Kris Buelens wrote: For VSE, what I learned: from the ASIPROC remove SET DATE remove SET ZONE remove SET ZONEDEF remove SET ZONEBDY Then VSE would take the definitions of the VM system under which it is running. You still need to reIPL the VSE guests when the timezone changes. For VMUTIL:no problems to expect. A bit simplified: a z Series has no timer to tell wake me up at hh:mm:ss; Wakeup allows hh:mm:ss. The z Series has wake me up in seconds. So VMUTIL converts the next coming hh:mm:ss it finds in its WAKEUP file into wakup up in xyz seconds. If the timezone changes in the mean time, VMUTIL won't see that. But, when the xyz seconds have elapsed, it'll wake up, execute what was wanted and scan its wakeup file again for anything that is either late (and wakeup directly) or the first coming event and set the xxx seconds timer again. etc 2009/10/13 David L.

(Especially with guests O/S's, like VSE, and timing related service machines, like VMUTIL). I come into the Data Center, bring down our VSE/ESA 1.7 and 2.2 virtual machines, SET TIMEZONE EST, and autolog the VSE machines back on. Some shops wait an hour but that hasn't caused us any problems. -- May the LORD God bless you exceedingly abundantly!
