Correct Jim, That is why we leave the system and most of the subsystems running and only keep down those subsystems (e.g. IMS) where we suspect the applications with the problems you mention.

It is the poorly written application programs which do not use the GMT time for their time stamps in whatever data records they are recording. Instead, way back when, they decided to use LOCAL time and then do computations on that LOCAL time field against CURRENT LOCAL time which gets them into trouble during the FALL BACK time change. > > DB2 uses the GMT Time to stamp the LOG records it is recording for recovery so that is not an issue. SMF records have GMT Time in them so that is not an issue. No it is the wonderfully written, old legacy applications which are at the root of the problem. > > ___________________________________________ > Jim Petersen > MVS - Lead Systems Engineer > Home Depot Technology Center > 1300 Park Center Drive, Austin, TX 78753 > www.homedepot.com > email:[email protected] > 512-977-2615 direct > 512-977-2930 fax > 210-859-9887 cell phone > > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Chase, John > Sent: Tuesday, March 29, 2011 5:32 AM > To: [email protected] > Subject: Re: Summer Time, "state of art" > > > -----Original Message----- > > From: IBM Mainframe Discussion List On Behalf Of Beesley, Paul > > > > In spring, we use the SET TIMEZONE=E.01.00 command on most of the > > systems we support, unless they haven't been IPL'ed for a while. > However > > in the autumn we still shutdown, wait an hour, and IPL. > > If you run 24x7 CICS, make sure it's setup to cope with the time > change > > ( I forget the SIT parameter ). > > I'm amazed and mystified that the arguably most sophisticated and mature > operating system in the world still cannot automatically handle the > changes to and from Daylight Saving Time. > > -jc- > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: GET IBM-MAIN INFO > Search the archives at http://bama.ua.edu/archives/ibm-main.html > > > The information in this Internet Email is confidential and may be legally privileged.
