Oracle12C architecture

Five important components

Services for connecting database instances: ways to work together in the architecture of the Oracle system

Server process

File system management

Memory area Management: especially the characteristics and functions of system Global area (SGA,SystemGlobal Area)

Background process

3 key architectures

Memory structure, process structure, storage structure

From the figure above, we can see that each Oracle server contains two main components, namely, Oracle instance and Oracle database (physical system).

Relationship between Oracle server, Oracle instance (instance), Oracle database (database)

The relationship between an instance and a database is that the database can be loaded and opened by multiple instances, while the instance can be loaded at any point in time to open a database

If Oracle is compared to a car, then the example is like the engine (core) of the car. Before starting Oracle, you must ensure that the instance starts first, and the goods pulled on the car are the database.

Oracle case system

When the database is started, the SGA (system global area) memory is automatically allocated to form the memory structure of Oracle, and then several memory-resident operating system processes are started, which has formed the process structure of Oracel. The memory area and background processes constitute an Oracle instance.

Each running Oracle database corresponds to an Oracle instance (or routine). When each instance starts, it allocates its own memory structure and process structure

Oracle instance tag: if there are multiple Oracle instances in the operating system (the instance name cannot be the same), you can use the environment attribute ORACLE_SID (or use INSTANCE_NAME) to annotate the default usage instance.

Memory structure

Memory stores data dictionary information, metadata about objects, logical structures, permissions, buffered application data, SQL statements, PL/SQL and Java program data, and transactions. In addition to these, it also includes the software code area and the program code area (PGA)

Shared area

(1)。 Include a high-speed buffer, a data dictionary buffer, a database high-speed buffer including a shared sql area, a private sql area, a shared PL/SQL area, and a control structure area

1)。 Private sql area: used to store private data for each session associated with the execution of a sql statement. In the dedicated server, the private sql zone exists in the PGA, and in the shared server, the private SQL zone exists in the shared area

2)。 Shared sql area: when a user executes sql, SQL stores the text of the most recently executed SQL statement, the compiled parse tree, and the execution plan in the shared area. Instead, the variable values in the sql statement are stored in the private Sql area. When the server executes the same sql statement again, the server process will no longer perform statement analysis, but will directly execute the content that already exists in the shared sql zone.

3)。 Shared PL/ SQL area: before Oracel executes a PL/SQL statement, the program unit will be placed in the shared PL/ SQL area, and the SQL statements within the program unit will be placed in the SQL area. When the same program unit needs to be executed again, it will be called directly from memory without having to access the disk again.

4)。 Structural control area: a section of memory area for internal use of an instance, which stores lock information

Database buffer

(1)。 This area is a cache area in SGA that stores data blocks, tables, and index databases that have recently been read from data files. When the user processes the query, the server process first looks for the required database from the database buffer, and accesses the disk data only when it is not in the buffer

Redo log buffer

(1)。 When the user changes the data through the sql statement, the server process records the changes in the redo log buffer. After an accident in the database, you can recover the data through this record

Daichi

(1)。 Optional memory area. Large pools provide additional memory for operations that consume a lot of memory

Java Pool

(1)。 Java text, syntax analysis and other information are stored there. If you want to install Java VM, you must enable Java pools

Streams Pool

(1)。 This area is newly added to 10g. It is used to store information. The content it stores is shared. It is easier to use the pool management information than to capture and manage messages.

Data dictionary buffer

(1)。 It contains the structure of the database, user information and database tables, views and other information, as well as all table and view nouns, permissions and other information.

Program global area (PGA)

(1)。 Program global area: including session information, stack space, sort area, and cursor status

1)。 Session information stores session permissions, roles, session performance statistics and other information.

2)。 Variables, arrays, and other information belonging to the session are stored in the stack space

3)。 The sorting area is a special space for sorting.

4)。 The cursor state is stored in the processing phase of various cursors currently in use.

(2)。 When the user process connects to the Oracle, the server creates a session and allocates a PGA zone that is used by a user process and cannot be shared

1)。 For dedicated servers (a database connection corresponds to a dedicated server process), PGA stores stack space information, session information, cursor state, and sort area.

2)。 For shared servers, PGA saves only stack space information, while session information, cursor state, and sort area are stored in SGA.

3)。 The structure of PGA is shown in the figure:

Three types of processes

User process, server process and background process, and the relationship between user process and server process, as shown in figure

(1)。

(2)。 When the user needs to operate in Oracle, the first step is to establish a connection so as to establish a communication channel between the user process and the server process. When the user has established a connection with the server, it will be expressed through a session that the operations between different sessions are independent of each other.

(3)。 The background process of Oracle starts at the same time as the instance, and its main function is to maintain the physical structure and memory structure of the database. The structure of the background process is as follows

The main functions of the background process in the above figure are as follows:

(1)。 System Monitoring process (SMON): when the database starts, SMON uses online redo log files to recover crashed instances

(2)。 Process monitoring process (PMON): mainly monitors the operation of the user process; when the user process fails, clear the resources occupied by the user process and the process

(3)。 Checkpoint process (CKPT): used to control data files, control files, and coordinate synchronization between redo log files

(4)。 Database write process (DBWO): this process is responsible for managing database buffers and data dictionary buffers

(5)。 Log writing process (LOWR): responsible for writing the contents of the redo log buffer to the online redo log file

(6)。 Archiving process (ARCO): restores full redo log files to a specified device to ensure that previous redo log files are not overwritten

(7)。 Recovery process (RECO): used to recover failed transactions in a distributed database environment

(8)。 Job queue process (SNPn): can perform periodic execution of some applications.

(9)。 Lock process (LCKn): used to lock database objects without being changed by other processes in the database.

Oracle physical system

The system is the physical system of the database, that is, the structure files stored on disk; all the data in the database is stored in these physical files.

Control files (Control file): control files are used to control the physical structure of the database. It records the control information of all files in the database.

Data files (Data File): each Oracle database has one or more physical data files. The data file of a database contains all the database data.

Redo log files (Log File): Oracle uses redo log files to keep logs of all database transactions

Parameter file (Parameter File): saves information about Oracle configuration. Generally, there are three types of parameter files:

(1)。 Initialization parameter file: used to configure the database when the database starts the instance. This file mainly sets the database instance name, the location of the file, the size of the memory area required by the instance, and so on.

(2)。 Configuration parameter file: it only exists when the data corresponds to multiple instances. If a database corresponds to only one instance, this file will not be generated. This file is generally named config.org and is usually called by the initialization parameter file.

(3)。 Binary parameter file: there will be two parameter files, one is pfile, which is a text-based parameter file that contains the configuration parameters of the database. Another Server Parameter File, the server parameter file, is a parameter file based on binary format and contains the parameters and values of databases and routines
