一、之前安装的是Oracle数据库的客户端，连接远程服务器上的oracle数据库的方法是：
二、后来重装系统，安装的是oracle，连接远程服务器上的oracle数据库的方法是：
1.打开程序－》Oracle-OraDB10g_home1－》Configuration and Migration Tools－》net configuration assistant
2.配置本地net服务名－》添加－》服务名(填要连接的远程服务器中的数据库名称)－》选择tcp协议－》主机名(填服 务器ip地址)－》是否测试(选择测试，如果不成功，则选择更改登入，输入用户名密码，然后重新测试)－》测试成功－》Net服务名(默认为上面填的服务名，可以不用改，改的话，则连接那里也要改)
//下面的监听，我没有配置，但是也可以使用。
3.监听程序配置－》添加－》监听程序名(只要还不存在的即可，不过最好填要连接的那个数据库名，方便以后查找)－》选择tcps和tcp－》使用标准端口号－》弹出框框，点击确定即可
4.点击完成
按照以上两种方法配置好了，如何进行连接？
方法一：在plsql的界面里：
用户名
口令
数据库
nomal
依次填写即可
就可以连接上远程服务器上的oracle数据库了
方法二：
点击SQLPLUS，弹出界面里，用户名、口令、主机字符串（配置的本地服务名）
即可连接上了
方法三：
在开始运行里输入cmd然后输入
sqlplus user_name/password@本地服务名
基本上说，连接远程服务器上的oracle数据库，需要配置“本地服务”，一个方面是通过图形界面（net configuration assistant ---其实是对文件的修改）一个是直接修改文件
打开程序－》Oracle-OraDB10g_home1－》Configuration and Migration Tools－》net configuration assistant
2.配置本地net服务名－》添加－》服务名(填要连接的远程服务器中的数据库名称)－》选择tcp协议－》主机名(填服 务器ip地址)－》是否测试(选择测试，如果不成功，，则选择更改登入，输入用户名密码，然后重新测试)－》测试成功－》Net服务名(默认为上面填的服务名，可以不用改，改的话，则连接那里也要改)
How do you handle database upgrades in MySQL?Apr 30, 2025 am 12:28 AMThe steps for upgrading MySQL database include: 1. Backup the database, 2. Stop the current MySQL service, 3. Install the new version of MySQL, 4. Start the new version of MySQL service, 5. Recover the database. Compatibility issues are required during the upgrade process, and advanced tools such as PerconaToolkit can be used for testing and optimization.
What are the different backup strategies you can use for MySQL?Apr 30, 2025 am 12:28 AMMySQL backup policies include logical backup, physical backup, incremental backup, replication-based backup, and cloud backup. 1. Logical backup uses mysqldump to export database structure and data, which is suitable for small databases and version migrations. 2. Physical backups are fast and comprehensive by copying data files, but require database consistency. 3. Incremental backup uses binary logging to record changes, which is suitable for large databases. 4. Replication-based backup reduces the impact on the production system by backing up from the server. 5. Cloud backups such as AmazonRDS provide automation solutions, but costs and control need to be considered. When selecting a policy, database size, downtime tolerance, recovery time, and recovery point goals should be considered.

How do you optimize database schema design for performance in MySQL?Apr 30, 2025 am 12:27 AMOptimizing database schema design in MySQL can improve performance through the following steps: 1. Index optimization: Create indexes on common query columns, balancing the overhead of query and inserting updates. 2. Table structure optimization: Reduce data redundancy through normalization or anti-normalization and improve access efficiency. 3. Data type selection: Use appropriate data types, such as INT instead of VARCHAR, to reduce storage space. 4. Partitioning and sub-table: For large data volumes, use partitioning and sub-table to disperse data to improve query and maintenance efficiency.

How to use MySQL functions for data processing and calculationApr 29, 2025 pm 04:21 PMMySQL functions can be used for data processing and calculation. 1. Basic usage includes string processing, date calculation and mathematical operations. 2. Advanced usage involves combining multiple functions to implement complex operations. 3. Performance optimization requires avoiding the use of functions in the WHERE clause and using GROUPBY and temporary tables.
An efficient way to batch insert data in MySQLApr 29, 2025 pm 04:18 PMEfficient methods for batch inserting data in MySQL include: 1. Using INSERTINTO...VALUES syntax, 2. Using LOADDATAINFILE command, 3. Using transaction processing, 4. Adjust batch size, 5. Disable indexing, 6. Using INSERTIGNORE or INSERT...ONDUPLICATEKEYUPDATE, these methods can significantly improve database operation efficiency.
Steps to add and delete fields to MySQL tablesApr 29, 2025 pm 04:15 PMIn MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
