Of course that means you have a fully redundant SYSPLEX set up with duplicated everything such that when you do have to bring down a CEC, the application workload is pushed to a different node and keeps running. -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Bob Bridges Sent: Tuesday, May 23, 2023 4:14 PM I'm just getting around to reading the article someone cited here: https://urldefense.com/v3/__https://www.linkedin.com/pulse/results-mainframe-application-modernization-migration-ross-mauri/ I heard that "8 9s" claim go by before, but I didn't pay much attention. But in the article it says that equates to 0.3 sec of downtime per year, and I pause. Does "down time" not include IPL, then? When you IPL, doesn't that count as "down"? Because if it doesn't, I don't see what use that measure is. Or does no one IPL any more? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ::DISCLAIMER:: ________________________________ The contents of this e-mail and any attachment(s) are confidential and intended for the named recipient(s) only.
