如何一步一步删除(Linux UNIX)环境下 Oracle 11g 集群节点
Deleting a Cluster Node on Linux and UNIX Systems
1.确定要删除的节点，是否active，pinned
$ olsnodes -s -t
如果 pinned ，则crsctl unpin css -n
2、禁用相应集群节点的应用资源，进程
先停掉 em：
emctl stop dbconsole
以root 用户运行 在要删除节点的 $Grid_home/crs/install 路径下运行rootcrs.pl 脚本
# ./rootcrs.pl -deconfig -force
如果要删除所有节点：
# ./rootcrs.pl -deconfig -force -lastnode
有时vip 资源不一定会被删除，这是需要手动来删除：
# srvctl stop vip -i vip_name-f
# srvctl remove vip -i vip_name-f
3、在其他节点执行以下命令：
crsctl delete node -n node_to_be_deleted
4、在要删除的节点上执行以下命令：
脚本在 ：$Grid_home/oui/bin
$ ./runInstaller -updateNodeList Oracle_HOME=Grid_home"CLUSTER_NODES={node_to_be_deleted}" CRS=TRUE -silent -local
5、清理要删除节点的Clusterware home 安装文件：
$ Grid_home/deinstall/deinstall –local
注意一定要添加 -local 选项 ，，否者会删除 所有节点的Clusterware home 安装目录.
6、在其他节点执行以下命令,更新节点信息：
脚本在 $Grid_home/oui/bin
$./runInstaller -updateNodeList ORACLE_HOME=Grid_home"CLUSTER_NODES={remaining_nodes_list}" CRS=TRUE -silent
7、验证要删除的节点是否已经成功删除：
$ cluvfy stage -post nodedel -n node_list[-verbose]

Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AMInnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
MySQL vs. Other Programming Languages: A ComparisonApr 19, 2025 am 12:22 AMCompared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.
Learning MySQL: A Step-by-Step Guide for New UsersApr 19, 2025 am 12:19 AMMySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.
MySQL: Essential Skills for Beginners to MasterApr 18, 2025 am 12:24 AMMySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.
MySQL: Structured Data and Relational DatabasesApr 18, 2025 am 12:22 AMMySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.
MySQL: Key Features and Capabilities ExplainedApr 18, 2025 am 12:17 AMMySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.
The Purpose of SQL: Interacting with MySQL DatabasesApr 18, 2025 am 12:12 AMSQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.
MySQL for Beginners: Getting Started with Database ManagementApr 18, 2025 am 12:10 AMThe basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA
