                                   【RMAN备份与恢复之单实例】

【主题:RMAN的简单的使用】
一、rman备份操作:
1.oracle用户登录,首先确定/u02/rman目录是否存在
2.使用sys用户,密码oracle 登录rman
rman target  sys/oracle
run{
CROSSCHECK  ARCHIVELOG  ALL;
ALLOCATE CHANNEL CH1 DEVICE TYPE DISK  FORMAT  '/u02/rman/test_%U' ;
ALLOCATE CHANNEL CH2 DEVICE TYPE DISK  FORMAT  '/u02/rman/test_%U';
BACKUP  incremental  level  0  DATABASE  plus  archivelog  delete  input;
RELEASE  CHANNEL  CH1;
RELEASE  CHANNEL  CH2;
}
RMAN>list backupset;

//备份完毕,一定要记录scn。
(备份时记录备份完成的SCN号,美国服务器,此SCN号作为数据库恢复的时间点,香港服务器租用,必须记录下来)
#SCN号类似如下:
--------------------------------------------------------------------------
二、rman 首次恢复操作
1、ORACLE用户登录
2、首次进行恢复
使用sys用户登录rman
rman target sys/oracle
shutdown immediate;
startup mount;
run{
set  until  scn  277970;
ALLOCATE CHANNEL CH1 DEVICE TYPE DISK  FORMAT  '/u02/rman/test_%U';
ALLOCATE CHANNEL CH2 DEVICE TYPE DISK  FORMAT  '/u02/rman/test_%U';
restore  database;
recover  database;
sql  'alter  database  open  resetlogs';
RELEASE CHANNEL CH1;
RELEASE CHANNEL CH2;
}
三、rman 多次恢复操作
在使用备份文件恢复数据库,用open resetlogs方式打开数据之后,
如果需要再次恢复数据库,需要指定数据库的incarnation.
1、ORACLE用户登录
2、进行恢复
使用sys用户登录rman
rman target sys/oracle
shutdown  immediate ;
startup mount;
list incarnation;
reset database to incarnation  1;
run{
set until scn 1;
ALLOCATE CHANNEL CH1 DEVICE TYPE DISK  FORMAT  '/u02/rman/test_%U';
ALLOCATE CHANNEL CH2 DEVICE TYPE DISK  FORMAT  '/u02/rman/test_%U';
restore database;
recover database;
sql 'alter database open resetlogs';
RELEASE  CHANNEL  CH1;
RELEASE  CHANNEL  CH2;
}

MySQL's Role: Databases in Web ApplicationsMySQL's Role: Databases in Web ApplicationsApr 17, 2025 am 12:23 AM

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

MySQL: Building Your First DatabaseMySQL: Building Your First DatabaseApr 17, 2025 am 12:22 AM

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL: A Beginner-Friendly Approach to Data StorageMySQL: A Beginner-Friendly Approach to Data StorageApr 17, 2025 am 12:21 AM

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.
