| What does Blackout date means in mainframe? I have got a maintanance schedule for whole year from my management. Some of the days are marked as "blackout dates". All I know for blackout is power shut. But I dont think it means power shut down in this case as many dates are marked as blackout dates in the schedule i got. I would really appreciate if some one could give more deatails on this and similar jargons used in mainframe environment. |

Hello,
Suggest you get the local definition from your manager.
A blackout will most likely be some kind of outage, but exactly what outage is site-specific to your organization/system.
At a couple of my sites, a blackout means some application(s) cannot be used for some period of time. Sometimes it means there can be no program/jcl promotions for that time period. I am not aware of an industry-wide accepted definition. |

| If it is a "maintanance schedule", the "Blackout date" may just be dates where no maintanance to production programs is allowed...... |

I came to know from my mgmt that..blackout dates are time periods where “no changes” are to be made to the environment. Some sites want the environments up and stable for certain events during the year and they are called blackout dates.
Thanks Dick and CICS Guy. |
