克隆一个已经存在的Oracle Home,免掉新安装oracle10g软件的痛苦,如果原Oracle Home已经安装了patch就省得打patch了。

一、在目标主机172.19.111.37上做安装前准备工作
1、增加组和用户(和克隆主机的目录结构一样)
# groupadd oinstall
# groupadd dba
# userdel oracle10
# useradd -g oinstall -G dba -d /opt/oracle/oracle10 -m -s /bin/ksh oracle10
# passwd -r files oracle10
2、建立需要的目录
# mkdir /opt/oracle/oradata/oracle10_data         (存放将来建库的数据文件)
# chown oracle10:oinstall /opt/oracle/oradata/oracle10_data
# chmod 755 /opt/oracle/oradata/oracle10_data
# mkdir /opt/oracle/oradata/flash_recovery_area         (存放将来建库的闪回文件)
# chown oracle10:oinstall /opt/oracle/oradata/flash_recovery_area
# chmod 755 /opt/oracle/oradata/flash_recovery_area
3、修改oratab文件权限
# more /var/opt/oracle/oratab
# chown oracle10:oinstall /var/opt/oracle/oratab
# chmod 755 /var/opt/oracle/oratab
4、停止已有的oracle监听进程。
# su - oracle
$ lsnrctl stop
$ sqlplus '/as sysdba'
SQL> shutdown immediate

二、停止和克隆主机172.19.111.38上ORACLE_HOME相关的所有进程
$ emctl stop dbconsole         (停Database Control)
$ lsnrctl stop         (停Net Listener)
$ isqlplusctl stop         (停iSQL*PLUS)
$ searchctl stop         (停Ultra Search)

三、对克隆主机ORACLE_HOME目录下内容打zip包
$ cd $ORACLE_HOME/../
$ zip -r db_1.zip /opt/oracle/oracle10/app/product/10.2.0/Db_1
注意,,不要把admin、flash_recovery_area、oradata目录打包,这些克隆后重新生成

四、拷贝zip包和.profile文件到目标主机
$ ftp 172.19.111.37
ftp> user oracle10 oracle10
上传db_1.zip和.profile

五、进入目标主机解压zip包
$ . .profile
$ unzip -d / db_1.zip

六、进入解压后的ORACLE_HOME目录,删除所有的$ORACLE_HOME/network/admin/*.ora文件
$ cd $ORACLE_HOME/network/admin
$ rm *.ora

七、以clone模式启动OUI(无需XBrower登陆),ORACLE_HOME_NAME要唯一
$ $ORACLE_HOME/oui/bin/runInstaller -silent -clone ORACLE_HOME="/opt/oracle/oracle10/app/product/10.2.0/Db_1" ORACLE_HOME_NAME="db_1"

八、新建数据库(得用XBrower登陆)
$ cd $ORACLE_HOME/bin
$ ./dbca

九、网络配置助手(得用XBrower登陆)
$ cd $ORACLE_HOME/bin
$ ./netca
分别做Listener configuration和Local net service name configuration(假设配置为orcl10)

十、测试
$ ps -ef | grep ora_         (检查oracle10g是否启动)
$ lsnrctl status         (检查监听是否启动)
$ tnsping orcl10         (检查配置的网络服务名是否正确)
$ emctl start dbconsole         (启动database console)
$ isqlplusctl start         (启动isqlplus)
进入 :5500/em/ 查看数据库状态信息

Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Explain the ACID properties (Atomicity, Consistency, Isolation, Durability).Apr 16, 2025 am 12:20 AM

ACID attributes include atomicity, consistency, isolation and durability, and are the cornerstone of database design. 1. Atomicity ensures that the transaction is either completely successful or completely failed. 2. Consistency ensures that the database remains consistent before and after a transaction. 3. Isolation ensures that transactions do not interfere with each other. 4. Persistence ensures that data is permanently saved after transaction submission.

MySQL: Database Management System vs. Programming LanguageMySQL: Database Management System vs. Programming LanguageApr 16, 2025 am 12:19 AM

MySQL is not only a database management system (DBMS) but also closely related to programming languages. 1) As a DBMS, MySQL is used to store, organize and retrieve data, and optimizing indexes can improve query performance. 2) Combining SQL with programming languages, embedded in Python, using ORM tools such as SQLAlchemy can simplify operations. 3) Performance optimization includes indexing, querying, caching, library and table division and transaction management.

MySQL: Managing Data with SQL CommandsMySQL: Managing Data with SQL CommandsApr 16, 2025 am 12:19 AM

MySQL uses SQL commands to manage data. 1. Basic commands include SELECT, INSERT, UPDATE and DELETE. 2. Advanced usage involves JOIN, subquery and aggregate functions. 3. Common errors include syntax, logic and performance issues. 4. Optimization tips include using indexes, avoiding SELECT* and using LIMIT.

MySQL's Purpose: Storing and Managing Data EffectivelyMySQL's Purpose: Storing and Managing Data EffectivelyApr 16, 2025 am 12:16 AM

MySQL is an efficient relational database management system suitable for storing and managing data. Its advantages include high-performance queries, flexible transaction processing and rich data types. In practical applications, MySQL is often used in e-commerce platforms, social networks and content management systems, but attention should be paid to performance optimization, data security and scalability.

SQL and MySQL: Understanding the RelationshipSQL and MySQL: Understanding the RelationshipApr 16, 2025 am 12:14 AM

The relationship between SQL and MySQL is the relationship between standard languages ​​and specific implementations. 1.SQL is a standard language used to manage and operate relational databases, allowing data addition, deletion, modification and query. 2.MySQL is a specific database management system that uses SQL as its operating language and provides efficient data storage and management.

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.

What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?What are the key metrics to look for in an EXPLAIN output (type, key, rows, Extra)?Apr 15, 2025 am 12:15 AM

Key metrics for EXPLAIN commands include type, key, rows, and Extra. 1) The type reflects the access type of the query. The higher the value, the higher the efficiency, such as const is better than ALL. 2) The key displays the index used, and NULL indicates no index. 3) rows estimates the number of scanned rows, affecting query performance. 4) Extra provides additional information, such as Usingfilesort prompts that it needs to be optimized.

What is the Using temporary status in EXPLAIN and how to avoid it?What is the Using temporary status in EXPLAIN and how to avoid it?Apr 15, 2025 am 12:14 AM

Usingtemporary indicates that the need to create temporary tables in MySQL queries, which are commonly found in ORDERBY using DISTINCT, GROUPBY, or non-indexed columns. You can avoid the occurrence of indexes and rewrite queries and improve query performance. Specifically, when Usingtemporary appears in EXPLAIN output, it means that MySQL needs to create temporary tables to handle queries. This usually occurs when: 1) deduplication or grouping when using DISTINCT or GROUPBY; 2) sort when ORDERBY contains non-index columns; 3) use complex subquery or join operations. Optimization methods include: 1) ORDERBY and GROUPB
