克隆Oracle Home(10g2)
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
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

MySQL: An Introduction to the World's Most Popular Database
Apr 12, 2025 am 12:18 AM
MySQL is an open source relational database management system, mainly used to store and retrieve data quickly and reliably. Its working principle includes client requests, query resolution, execution of queries and return results. Examples of usage include creating tables, inserting and querying data, and advanced features such as JOIN operations. Common errors involve SQL syntax, data types, and permissions, and optimization suggestions include the use of indexes, optimized queries, and partitioning of tables.
Why Use MySQL? Benefits and Advantages
Apr 12, 2025 am 12:17 AM
MySQL is chosen for its performance, reliability, ease of use, and community support. 1.MySQL provides efficient data storage and retrieval functions, supporting multiple data types and advanced query operations. 2. Adopt client-server architecture and multiple storage engines to support transaction and query optimization. 3. Easy to use, supports a variety of operating systems and programming languages. 4. Have strong community support and provide rich resources and solutions.
How to solve the problem of closing oracle cursor
Apr 11, 2025 pm 10:18 PM
The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.
How to create cursors in oracle loop
Apr 12, 2025 am 06:18 AM
In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.
How to create oracle dynamic sql
Apr 12, 2025 am 06:06 AM
SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.
What to do if the oracle can't be opened
Apr 11, 2025 pm 10:06 PM
Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.
How to read the oracle awr report
Apr 11, 2025 pm 09:45 PM
An AWR report is a report that displays database performance and activity snapshots. The interpretation steps include: identifying the date and time of the activity snapshot. View an overview of activities and resource consumption. Analyze session activities to find session types, resource consumption, and waiting events. Find potential performance bottlenecks such as slow SQL statements, resource contention, and I/O issues. View waiting events, identify and resolve them for performance. Analyze latch and memory usage patterns to identify memory issues that are causing performance issues.
How to use triggers for oracle
Apr 11, 2025 pm 11:57 PM
Triggers in Oracle are stored procedures used to automatically perform operations after a specific event (insert, update, or delete). They are used in a variety of scenarios, including data verification, auditing, and data maintenance. When creating a trigger, you need to specify the trigger name, association table, trigger event, and trigger time. There are two types of triggers: the BEFORE trigger is fired before the operation, and the AFTER trigger is fired after the operation. For example, the BEFORE INSERT trigger ensures that the age column of the inserted row is not negative.
