Most of the IMS engineers know that DEDBs are different than Full function databases. But the internal mechanics, the randomizer, the area structure, the buffer pool, the overflow behavior, the locking model; remain a black box even for experienced practitioners who work with Fast Path databases every day. That gap matters, when a DEDB area fills unexpectedly, when OTHREAD contention spikes at peak load, when a randomizer design from fifteen years ago is causing area imbalance today, when an FPSI is slowing down inserts instead of speeding up reads. The engineer who understands the internals diagnoses in minutes. The engineer who does not spends hours reading logs without knowing what to look for. This session opens the Fast Path engine. Piece by piece, concept by concept. We build the complete internal picture of how DEDB works — from the moment a key arrives to the moment data is returned, and everything that can go wrong in between.
