Ubuntu安装Oracle 11g XE在Configure时的罕见问题?
我只能说好像我已经解决了这个Configure问题,但是我还是想建议一下你在按下回车键时确认一下输入法的问题,这是我事后感觉出来的。
相信你肯定已经在网上搜过了,关于这个问题的解答好像还是找不到答案,我个人感觉这应该是那种突发性小事件,估计就是一些小地方影响了你的Oracle配置,大家都很着急,那么我就把我的解决方法告诉你好了。
1、无论是哪里的资料,一定会说要 sudo /etc/init.d/oracle-xe configure,然后我出现了"sudo: /etc/init.d/oracle-xe: command not found",结果只要改成sudo sh /etc/init.d/oracle-xe configure就行了。
2、然后在它提示我输入端口号时,,不管我干什么,它总是说"Invalid Http Port: ****"。亲自打开oracle-xe这个文件,定位到echo "Invalid http port: $LINE"直接在下面指定你的端口(如HTTP_PORT=8080;记得加上break语句),有兴趣的话自己做个实验就知道了。同理你会发现后面又要指定监听端口时也是这个错误,同样直接在下面指定你的端口(如LISTENER_PORT=1521;记得加上break语句),到这里应该就能成功了。
3、祝你好运,因为这个问题我在网上找了好久没找着。

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

The main role of MySQL in web applications is to store and manage data. 1.MySQL efficiently processes user information, product catalogs, transaction records and other data. 2. Through SQL query, developers can extract information from the database to generate dynamic content. 3.MySQL works based on the client-server model to ensure acceptable query speed.

The steps to build a MySQL database include: 1. Create a database and table, 2. Insert data, and 3. Conduct queries. First, use the CREATEDATABASE and CREATETABLE statements to create the database and table, then use the INSERTINTO statement to insert the data, and finally use the SELECT statement to query the data.

MySQL is suitable for beginners because it is easy to use and powerful. 1.MySQL is a relational database, and uses SQL for CRUD operations. 2. It is simple to install and requires the root user password to be configured. 3. Use INSERT, UPDATE, DELETE, and SELECT to perform data operations. 4. ORDERBY, WHERE and JOIN can be used for complex queries. 5. Debugging requires checking the syntax and use EXPLAIN to analyze the query. 6. Optimization suggestions include using indexes, choosing the right data type and good programming habits.
