A DEDB area is corrupt. A full-function database has stopped with RECOVER NEEDED. The batch window opens in a few hours, and the city needs to run. IMS database recovery is one of the most critical skills in enterprise computing and one of the least formally taught. Most engineers learn it under pressure, piecing together the log chain, reading RECON messages they have never seen before, and hoping the image copy they took last week is still valid. That is exactly the wrong moment to be learning. This session changes that. Delivered from two perspectives, an IMS recovery specialist and a Fast Path database engineer. We cover the complete IMS recovery story from the ground up. The recovery specialist brings the breadth: the full mechanics of the IMS log chain, DBRC, RECON, image copies, change accumulation, and GENJCL across databases. The Fast Path engineer brings the depth: a real-world Fast Path DEDB recovery — from area corruption through area-level GENJCL, FPSI integrity checking, and the moment the area comes back online, showing exactly how the general recovery principles apply to the most database architecture in IMS. Together, we cover what happens when things go wrong and more importantly, what you need to have done before they do.
