Scheduled mainframe outages will occur once each month. The scheduled outages each month will occur at 6:00 p.m. and end at 9:00 p.m. Outages will be abbreviated or canceled when possible. Operations may actually quiescence online applications (TSO, ROSCOE, CICS, etc.) anytime between 5:00 p.m. and 6:00 p.m. If you are working online during this interval, you could lose your connection. Perform frequent 'saves' to protect your changes.
Twice per year, OIT schedules longer outages. In 2015, two possible extended outages are currently scheduled and will occur on May 15, 2015 and September 13, 2015, from 6:00 a.m. until midnight. If maintenance schedules do not require an extended outage, the outage will be shortened to a regular 6:00 p.m. – 9:00 p.m. outage or canceled.
