Now the industry of mobile payment is very chaotic, there are many legal and competitive payment methods, countless startups, industry giants, banking institutions, joint ventures and so on want to share from this market. In the big companies, the deer dominate the role of the time, consumers must wait for the change and patience. In the past few years, we have seen Square, Google, Intuit and other companies have issued a unique e-wallet. While mobile payments are the highlight of this year's C

Label:Memory structureIn modern computers, the CPU accesses memory more than a few times faster than the disk, so Oracle accesses the data as much as possible in memory, rather than directly modifying the data on the hard disk. Memory content is synced to disk at the right time. Oracle uses memory to overcome the constraints of disk IO, the more activity in memory, the better the system performance, conversely, the more operations on disk, the system performance is worse.

When an Oracle database instance is started, it needs to allocate shared memory to start background processes. The memory used by the Oracle database mainly involves PGA and SGA. 1.
