payment method. However, there are also many notable cases. Google Wallet can only be used on mobile phones embedded with near-field communication (NFC) chips, which can implement secure electronic payment in a small range. In Japan, millions of mobile phone users have used the Mobile Wallet service through NFC chips, but the technology has been slowly promoted in other countries. Currently, Nexus S 4G is the only mobile phone in the United States that can use Google Wallet, but more mobile pho

Oracle memory structure and instance Management 1. Memory Structure: The overall structure of the Oracle database is as follows: Each Oracle database is composed of an Oracle Instance and a database (data file, control file, and redo log file). The so-called Instance is the medium for the user to interact with the database, you can operate a database by connecting to an instance. The instance is composed of a unified memory structure (SGA, PGA, UGA) a

tells us that oracle logs will generate a large number of logs. 3) actual log generation process The actual log generation process has some performance problems. The teacher drew a lot of pictures in the course. His diagram is casual, but it should be said that it has a meaningful meaning. The student himself did not draw his picture because he only wanted to use words to describe the course. The memory has a sharedpool, Buffercache and logbuffer correspond to the dbf and redolog on the disk. O

It contains data and control information of the Oracle server. It is allocated in the actual memory of the computer

However, the user process cannot interact directly with the database, and it must be connected to the server's component server process.Server process: An explanation of the SQL statements passed by the user process, responsible for commit and rollback, participating in IO.

That is: Oracle Server = Oracle Instance + Oracle Database One, Oracle instance Oracle instances include a memory structure (SGA) and a series of background processes (Background process), which together are called an Oracle instance: Oracle Instance = SGA + Background Pro Cess Or

Oracle Memory ArchitectureThe basic memory structures associated with Oracle instances include:System global Area (SGA): shared by all servers and background processes. Examples of data stored in the SGA include cached data blocks and shared SQL regions.Program Global Zone (PGA): Individual server processes and background processes are dedicated, each process has a PGA.The SGA is a shared memory area that contains data and control information for the

When a user is created, Oracle automatically creates a pattern that is the same as the user name, so the pattern is also known as user mode.When a user logs on, the default access is the number library object in the same mode as their own name.Third, Oracle's memory structureMemory is the first element t

option provided by Oracle that allows operations on multiple computers in a clustered environment so that multiple instances can mount and open a database (on a shared set of physical disks) at the same time.As a result, we can access this database from several different computers at the same time. Oracle RAC supports highly available systems that can be used to build a solution that is very scalable.An instance is the name of the memory structure that governs the associated library (the SGA,

Oracle's memory configuration is tied to Oracle performance. In general, it can be divided into two chunks: the shared portion (mainly the SGA) and the process-exclusive portion (mainly the PGA). In Oracle versions under 32-bit operating systems, it is very frustrating to have project feedback on memory errors (such as ORA-04030, 04031 errors) from time to times. Consult the data to understand that the ORA-04030 problem is generally caused by the
