在有些情况下,如数据库服务器处于磁盘空间的压力或成本控制需要将数据文件备份到异机,使用RMAN可以完成该工作。基于Windows平台

在有些情况下,如数据库服务器处于磁盘空间的压力或成本控制需要将数据文件备份到异机,使用RMAN可以完成该工作。基于Windows平台所需完成的配置相对简单,仅仅是添加账户与使用新增的帐户来启动数据库服务以及设置共享路径。

下面给出具体描述。
    
一、配置数据库服务器与备份目的主机
    1. 帐户配置(假定有主机A,B 且A为数据库服务器,B为备份目的主机,且能互相ping通)    
            如果主机A与主机B使用的Administrator密码相同,且A上的OracleServiceDBNAME服务和OracleOraHome92TNSListener服务都以"本
        地系统账户登陆"
            如果主机A与主机B使用不同的Administrator密码,处于安全考虑不宜设为相同,则则可以分别在主机A与主机B上新建一用户,假
        定在主机A上建立DBA_oracle,密码为ORA_PWD,则在主机B上也建立该用户(用户名可以不同,密码必须相同),密码同样设置为ORA_PWD
        。将刚建好的用户在各自主机将其加入到Aministrators组
    2. 设定OracleServiceDBNAME服务和OracleOraHome92TNSListener服务的启动帐户。在运行处输入services.msc。在主机A上设定使用此帐
        户登陆,即使用刚刚建立的DBA_oracle,,输入密码启动,该设置需要重启后有效
    3. 在主机B上设定共享文件夹,如RMAN_Shared,设置其权限为完全控制(在A上使用\\IP\RMAN_Shared测试是否可写入文件)
        
二、查看RMAN的配置与数据库情况

三、备份数据库并关闭数据库,删除system01.dbf文件
    使用备份脚本对数据库进行备份,备份脚本在最后给出

  • D:\>rman target robinson/robin@testhh cmdfile=D:\oracle\oradata\testHH\backup.rman log=D:\oracle\ora    
  • data\testHH\backup.log                                                                                  
  • 四、从异机进行还原与恢复
        1.关闭数据库      2.删除system01.dbf数据文件以便测试恢复

    SQL> ho del D:\oracle\oradata\testHH\SYSTEM01.DBF  

        3.重启实例,收到错误提示     4.使用RMAN进行还原与恢复     5.结论
                从上面的备份与恢复来看,使用异机备份与恢复与使用本地服务器备份与恢复操作方式并无太多差异,但数据库的性能则受到一定
            的影响。即备份到异机其备份与恢复速度低于备份恢复在本地服务器。在大型生产环境中且实时性要求特高的情形,尽可能的避免异机
            备份与恢复。尽管如此,备份到异机与从异机恢复仍然不失为一种可选方案。

    五、RMAN 备份脚本

    When might a full table scan be faster than using an index in MySQL? When might a full table scan be faster than using an index in MySQL? Apr 09, 2025 am 12:05 AM

    Full table scanning may be faster in MySQL than using indexes. Specific cases include: 1) the data volume is small; 2) when the query returns a large amount of data; 3) when the index column is not highly selective; 4) when the complex query. By analyzing query plans, optimizing indexes, avoiding over-index and regularly maintaining tables, you can make the best choices in practical applications.

    Can I install mysql on Windows 7 Can I install mysql on Windows 7 Apr 08, 2025 pm 03:21 PM

    Yes, MySQL can be installed on Windows 7, and although Microsoft has stopped supporting Windows 7, MySQL is still compatible with it. However, the following points should be noted during the installation process: Download the MySQL installer for Windows. Select the appropriate version of MySQL (community or enterprise). Select the appropriate installation directory and character set during the installation process. Set the root user password and keep it properly. Connect to the database for testing. Note the compatibility and security issues on Windows 7, and it is recommended to upgrade to a supported operating system.

    InnoDB's full-text search capabilities are very powerful, which can significantly improve database query efficiency and ability to process large amounts of text data. 1) InnoDB implements full-text search through inverted indexing, supporting basic and advanced search queries. 2) Use MATCH and AGAINST keywords to search, support Boolean mode and phrase search. 3) Optimization methods include using word segmentation technology, periodic rebuilding of indexes and adjusting cache size to improve performance and accuracy.

    MySQL: Simple Concepts for Easy Learning MySQL: Simple Concepts for Easy Learning Apr 10, 2025 am 09:29 AM

    MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.

    Difference between clustered index and non-clustered index (secondary index) in InnoDB. Difference between clustered index and non-clustered index (secondary index) in InnoDB. Apr 02, 2025 pm 06:25 PM

    The difference between clustered index and non-clustered index is: 1. Clustered index stores data rows in the index structure, which is suitable for querying by primary key and range. 2. The non-clustered index stores index key values ​​and pointers to data rows, and is suitable for non-primary key column queries.

    Can mysql and mariadb coexist Can mysql and mariadb coexist Apr 08, 2025 pm 02:27 PM

    MySQL and MariaDB can coexist, but need to be configured with caution. The key is to allocate different port numbers and data directories to each database, and adjust parameters such as memory allocation and cache size. Connection pooling, application configuration, and version differences also need to be considered and need to be carefully tested and planned to avoid pitfalls. Running two databases simultaneously can cause performance problems in situations where resources are limited.

    The relationship between mysql user and database The relationship between mysql user and database Apr 08, 2025 pm 07:15 PM

    In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database. Permissions are granted through the GRANT command, while the table is created by the CREATE TABLE command. To establish a relationship between a user and a database, you need to create a database, create a user, and then grant permissions.

    RDS MySQL integration with Redshift zero ETL RDS MySQL integration with Redshift zero ETL Apr 08, 2025 pm 07:06 PM

    Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.
