That must have been subsequent to March of 2001. Everyone remember the *APAR OF DEATH", OW45398?
After 51 days of running OS/390 2.10 without an IPL, and all of the sudden, "What happened???" Of course, a few days later I heard the warning from Jerry Ng. But as the song "The Streak" quoted, "It was too late. Ethel (the problem) had already gotten a free shot". :-) Bob -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Hal Merritt Sent: Thursday, September 03, 2009 11:18 AM To: [email protected] Subject: Re: How often IPL a production LPAR (any good practice) I can remember the day when a weekly IPL was almost mandatory. But that was long ago. I believe the current technology is to schedule an IPL to implement z/os software changes. If there are no changes, then no IPL. You may run into misbehaving applications that suffer from storage creep, or you may need to reclaim ASID's marked unusable. I think we ran for over a year once with no noticeable issues. -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Tommy Tsui Sent: Wednesday, September 02, 2009 8:09 PM To: [email protected] Subject: How often IPL a production LPAR (any good practice) Hi all, Is there any concern if we didn't IPL a LPAR over three months. Is there any good practise to follow from IBM. They always replied LPAR never needs IPL because of 24 x 7. ---------------------------------------------------------------------- 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
