Solaris上Oracle数据库开机自动启动方法总结:
一、Solaris上开机自动启动
Solaris在开机时,会自动运行/etc/rc.d目录下的所有脚本,其中N越大,执行的级别越高。其中,S开头的脚本在开机时自动运行,K开头的脚本在关机时自动运行。
二、Oracle上的启动脚本
启动脚本可以自己编写,也可以使用Oracle自带的启动和关闭数据库的脚本。
Oracle自带脚本:$ORACLE_HOME/bin/dbstart、$ORA_HOME/bin/dbshut
特别需要注意的是:dbstart中的参数PFILE可能存在问题,需要手动修改。
1、如在oracle用户下运行dbstart命令没有反应,,则需要在文件/var/opt/oracle/oratab中将“ora:/export/home/oracle/product/9.2:N”修改为“ora:/export/home/oracle/product/9.2:Y”。
三、设置Oracle自动启动步骤(使用Oracle自带脚本)
1、修改dbstart、dbshut脚本,保证直接运行时可启动和关闭数据库;
2、新建调用dbstart、dbshut的脚本dbora放置在/etc/init.d目录下,dbora的内容如下:
#!/bin/sh
ORA_HOME=/export/home/oracle/app/oracle/products/9.2.0
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup:cannot start"
exit
fi
case "$1" in
'start' )
su - $ORA_OWNER -c $ORA_HOME/bin/dbstart &
/etc/init.d/dblsnrctl.sh
;;
'stop' )
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut &
;;
esac
3、新建启动lsnrctl的脚本dblsnrctl.sh(dbora脚本将调用此脚本)防止在/etc/init.d目录下,dblsnrctl.sh的内容如下:
#!/bin/sh
su - oracle
lsnrctl start
exit
4、修改dbora脚本和dblsnrctl.sh脚本的权限,以保证可运行:
#chmod 755 /etc/init.d/dbora
#chmod 755 /etc/init.d/dblsnrctl.sh
5、在/etc/rc2.d中设置启动链接:
#cd /etc/rc2.d
6、在/etc/rc0.d中设置关闭链接:
#cd /etc/rc0.d

InnoDBBufferPool 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.

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 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 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 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 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.

SQL 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.

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
