Claims, Drains, and Automobiles
Marcus Davage – Lead Product Developer
BMC Software Ltd.
Picture a bustling metropolis: thousands of people crossing streets, driving cars, and getting to work. It would be chaos without traffic lights, police officers, or laws. In Db2 for z/OS, that metropolis is data, transactions, utilities, queries, Units of Work. Claims, Drains, Locks, and Latches are the silent traffic controllers keeping the peace.
This presentation explains these concepts using memorable, amusing, everyday illustrations, and with examples, shows why they matter.
