36. 36 ScenarioFlaw 1. Concurrent ADABAS DELETE occurs before the loader has extracted the base record. RDBMS replication of the DELETE fails due to row not found. 2. Concurrent ADABAS INSERT occurs before the loader has extracted the base record. A duplicate row is both replicated and then loaded to the RDBMS. 3. Concurrent ADABAS UPDATE occurs before the loader has extracted the base record. RDBMS replication of the UPDATE fails due to row not found. Etc.
