一、停止数据库相关进程
分别在两台机器上停止数据库
sqlplus "/as sysdba";
sql>shutdown immediate
lsnrctl stop

也可以用srvctl工具在一个节点上完成
$ORA_CRS_HOME/bin/srvctl stop service -d rac 停止service.(对于RAC数据库,首先要停止所有节点中的Service服务,如果创建了service的话)
$ORA_CRS_HOME/bin/srvctl stop database -d rac 停止RAC数据库中所有实例
$ORA_CRS_HOME/bin/srvctl stop listener -n racnode1 停止节点racnode1上监听
$ORA_CRS_HOME/bin/srvctl stop listener -n racnode2 停止节点racnode2上监听
二、安装clusterware补丁
su - Oracle
cd /home/oracle/Disk1
./runInstaller
弹出OUI的欢迎窗口后,,直接点击下一步:
选择软件的目录,这里我们要首先选择OraCrs10g的主目录,点击Name中的下拉框,选择oracrs10g_home
OUI 自动选中了所有可用的节点,直接点击下一步
安装环境的检查,如无异常,直接点击下一步即可:(在安装oracle软件时没有问题的话,这个应该也没有太大问题)
显示摘要信息,如无异常点击install
安装结束退出(在结束的时候,会出现一个提示信息,让你分别关掉两个节点的crs服务,并执行root102.sh脚本,步骤如下)
以root用户登陆
/etc/init.d/init.crs stop
sh $ORA_CRS_HOME/install/root102.sh (其中$ORA_CRS_HOME在root用户中没有定义环境变量,请输入实际的全路径)
三、安装数据库软件补丁
由于前面执行root102.sh时,会自动重新crs,因此在升级数据库软件前,需要执行第一步中停止相关进程的操作,比如依次关闭数据库、监听等服务
弹出OUI的欢迎窗口后,直接点击下一步:
选择软件的目录,这里我们要首先选择OracDb的主目录,点击Name中的下拉框,选择oradb10g_home1
OUI 自动选中了所有可用的节点,直接点击下一步
安装环境的检查,如无异常,直接点击下一步即可
提示是否要绑定metalink,可以根据实际情况进行选择
如无问题直接点击install
在此期间,OUI会自动弹出窗口如下,提示在RAC环境中的各个节点执行指定的root.sh脚本,注意是以root身份执行:
四、升级数据库(可以通过两种方法来实现,dbua和执行脚本的方式)
首先我们以dbua图形界面的方式来实现
对于RAC数据库环境下的升级,首先需要启动各节点的监听服务,操作如下:
$ORA_CRS_HOME/bin/srvctl start listener -n racnode1
$ORA_CRS_HOME/bin/srvctl start listener -n racnode2
执行dbua命令,通过视窗界面选择升级数据库:
选择要升级的(并且当前可用的数据库),这里只有一个并已被默认选中,然后输入sys用户密码:
选择是否在升级后自动编译无效的对象,默认是选中的,直接按下一步
开始执行升级,本步操作较多,费时较久,请耐心等待:
述操作完成后,点击ok即可,OUI弹出整个操作的返回结果
点击close按钮关闭窗口。
此时可以登陆任意节点,以sqlplus命令行连接进去查询数据库的版本:
sqlplus "/ as sysdba"
sql>select * from gv$instance;
确认无误后,升级完成
另一种方法是以脚本的方式来实现
在升级数据库的时候,要确保crs的相关服务和监听服务都要启动
启动到nomount状态修改参数
sqlplus "/as sysdba"
SQL>STARTUP NOMOUNT
SQL> ALTER SYSTEM SET CLUSTER_DATABASE=FALSE SCOPE=spfile;
SQL> SHUTDOWN
重建数据字典
SQL> STARTUP UPGRADE
SQL> SPOOL patch.log
SQL> @$ORACLE_HOME/rdbms/admin/catupgrd.sql #此处执行时间较长
SQL> SHUTDOWN IMMEDIATE
SQL> SPOOL OFF
编译无效对象
SQL> STARTUP
SQL>@$ORACLE_HOME/rdbms/admin/utlrp.sql
SQL>ALTER SYSTEM SET CLUSTER_DATABASE=TRUE scope=spfile;
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP
升级后检查升级是否成功
su – oracle
sqlplus "/as sysdba"
SQL> SELECT COMP_NAME, VERSION, STATUS FROM SYS.DBA_REGISTRY;
SQL>select * from gv$instance;

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

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),

SecLists
SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
