The db2 Tutorial we are reading is: DB2 common dummies 1000 (1 ). When applying DB2, you may encounter some seemingly simple problems, especially for beginners.To sum up, I will release it to you. I hope it will be helpful to you. At the same time, you are welcome to discuss, develop, and make progress together! The characters below are mainly in lower case based on DB27.X.This article does not need to be viewed by DB2 experts.

Einstein came up with such a mathematical problem: there is a long ladder, if each step across 2, then the last one, if each step across 3, then the last 2 order, if each step across the 5-order, then the last 4 order, if each step across the 6-order, the last remaining 5 order. Only 7 steps at a time, the end is just the first order of no left. How many steps ar

rollback segment that modifies the data and the SCN, and then updates the data in the buffer cache and its SCN, and identifies it as "dirty" data. When another process reads a block of data, it first compares the SCN on the data block and its own SCN. If the SCN on the block is less than the SCN of the process itself, the data on the data block is read directly, and if the SCN on the block is greater than the process itself, the modified block reads the data from the rollback segment. Generally
