使用Java JDK 1.5或者1.6
Use JDK 6 (Java SE Development Kit 1.6.0_21) or JDK 5 (1.5.0_24) with the JNDI extension with the Oracle Java Database Connectivity and Oracle Call Interface drivers. However, these are not mandatory for the database installation. Note that JDK 1.5 is installed with this release.
以下是对操作系统的配置文件的修改vim /etc/profile
Use a text editor to open the /etc/profile file of the Oracle Grid Infrastructure installation owner, and find the following line:
ulimit –S –c 0 > /dev/null 2>&1
Change it to the following:
ulimit -S -c unlimited > /dev/null 2>&1
Use a text editor to open /etc/sysctl.conf, and find the following line:
kernel.core_uses_pid
Confirm that it is set to 1. This setting appends the PID to the generated core file, which allows multiple core file dumps.
If kernel.core_uses_pid is missing, then add the following line:
kernel.core_uses_pid = 1
Find the following line:
fs.suid_dumpable
By default, this value is set to 0. Change it to 1.
If fs.suid_dumpable is not in the sysctl.conf file, then add the following line:
fs.suid_dumpable = 1
Save /etc/sysctl.conf, and use the following command to reload settings:
# sysctl -p
添加安装的用户组和用户:
[root@oracle ~]# groupadd oinstall
[root@oracle ~]# groupadd dba
[root@oracle ~]# useradd -g oinstall -G dba oracle
继续修改系统参数/etc/sysctl.conf在/etc/security/limits.conf最后添加:# End of file
oracle soft nproc 2047
oracle hard nproc 16384
oracle soft nofile 1024
oracle hard nofile 65536
oracle soft stack 10240
oracle hard stack 20480除了最后一项全部是按照oracle推荐最保守设置。
创建安装目录
这里创建的是/oracle
设置好权限和所有者 chown -R oracle:oinstall /oracle
创建安装目录,,修改oracle 家目录下.bash_profile
在其后添加
# added by qitianwu
TMP=/oracle/tmp
TMPDIR=/oracle/tmp
export TMP TMPDIR
ORACLE_BASE=/oracle/app/oracle
ORACLE_SID=sales
export ORACLE_BASE ORACLE_SID
之后以root身份执行 xhost +
此命令表示,允许任意用户从任意的主机上运行图形命令
以oracle用户登录shell
su – oracle
进入oracle目录 执行./runInstaller
之后图形化配置按照指引一步步完成即可。

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
