### 以此注释后面的内容在系统shell中运行 --- 以此注释后面的内容在Sqlplus中运行 ### 1、取得oracle用户的环境 su - o
### 以此注释后面的内容在系统shell中运行
--- 以此注释后面的内容在Sqlplus中运行
### 1、取得Oracle用户的环境
su - oracle
cd /oracle
source .cshrc
### 显示当前Oracle10gRAC/crs运行情况
crs_stat -t
### 2、关闭Oracle,注意 dbser1 为AIX主机名称
### 连接 Oracle
sqlplus /nolog
conn /as sysdba
--- 关闭实例
shutdown immediate
input "press to continue..."
exit
### 3、关闭节点
srvctl stop nodeapps -n dbser1
crs_stat -t
exit
### 关闭crs
/etc/init.crs stop
### 完成关闭
--- 4、在sqlplus中启动或关闭实例
--- 关闭实例
shutdown immediate;
--- 启动实例
startup;
--- 5、调整SGA,需重新启动
alter system set sga_max_size=4000M scope=spfile;
alter system set sga_target=4000M scope=spfile;
--- 重启实例完成参数应用
--- 关闭实例
shutdown immediate;
--- 启动实例
startup;
--- 6、等上一步骤完成重启后,分配缓存和池的大小
alter system set shared_pool_size=1048M scope=spfile;
alter system set db_cache_size=1024M scope=spfile;
alter system set large_pool_size=208M scope=spfile;
alter system set java_pool_size=112M scope=spfile;
--- 重启实例完成参数应用
--- 关闭实例
shutdown immediate;
--- 启动实例
startup;
--- 7、显示缓存和池的大小
show parameter sga_max_size;
show parameter sga_target;
show parameter db_cache_size;
show parameter shared_pool_size;
show parameter large_pool_size;
show parameter java_pool_size;
show parameter pga_aggregate_target;
--- 8、关于Oralce的配置文件修改的问题
--- 从当前配置spfile创建pfile文本文件/oracle/10.2/db_1/dbs/NARICOM.ora
create pfile='/oracle/10.2/db_1/dbs/NARICOM.ora' from spfile;
--- 实例处于关闭时,可恢复系统配置
--- 从pfile(文本)文件/oracle/10.2/db_1/dbs/NARICOM.ora创建系统配置spfile(二进制)文件
create spfile from pfile='/oracle/10.2/db_1/dbs/NARICOM.ora';
### 9、启动Oracle/crs,root用户下,自动启动本机实例
/oracle/10.2/crs/bin/crsctl start crs
--- 10、更改转换字符集为GBK
shutdown immediate;
startup mount;
alter system enable restricted session ;
alter system set JOB_QUEUE_PROCESSES=0;
alter system set AQ_TM_PROCESSES=0;
alter database open;
--- 当处于集群时,需要将pfile中 cluster_database改为false到spfile启动Exclusive模式
ALTER DATABASE character set INTERNAL_USE ZHS16GBK;
shutdown immediate;
startup;
select name,value$ from props$ where name like '%NLS%';
### 11、集群信息查看操作

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.

InnoDB uses redologs and undologs to ensure data consistency and reliability. 1.redologs record data page modification to ensure crash recovery and transaction persistence. 2.undologs records the original data value and supports transaction rollback and MVCC.

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Compared 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.

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.

The 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

MySQL is suitable for web applications and content management systems and is popular for its open source, high performance and ease of use. 1) Compared with PostgreSQL, MySQL performs better in simple queries and high concurrent read operations. 2) Compared with Oracle, MySQL is more popular among small and medium-sized enterprises because of its open source and low cost. 3) Compared with Microsoft SQL Server, MySQL is more suitable for cross-platform applications. 4) Unlike MongoDB, MySQL is more suitable for structured data and transaction processing.
