用Oracle9ias开发无线应用程序开发者网络Oracle
正在看的ORACLE教程是:用Oracle9ias开发无线应用程序开发者网络Oracle。Oracle 移动服务的中心组件 Oracle Application Server Wireless (OracleAS Wireless) 是一个灵活的无线和语音综合平台，可以使任何公司的联系扩展到其公司范围以外。利用 Oracle9iAS Wireless，企业可以部署基于无线浏览器的应用程序、语音应用程序、通告、Java 2 Micro Edition (J2ME) 应用程序和双路消息处理 (Ask) 应用程序(其功能如图1 所示)。Oracle9iAS Wireless 构建于 Oracle Application Server 9i 和 Oracle Database 9i 上，提供市场上最具有伸缩性、可靠而经济高效的移动基础架构，以实施企业的移动战略。

下面以一个最简单的hello world为例简单介绍一下是如何用Oracle9ias开发无线应用程序的：
1、写一个简单的名为hello world XML网页，并将它发布到本地WEB服务器上
1-1. 在.. \iaswv20\wireless\j2ee\default-web-app目下新建一个名为"walkthrough" 的目录
1-2. 在.. \iaswv20\wireless\j2ee\default-web-app\walkthrough新建一个名为 helloworld.xml的文件，其内容如下：
2、用浏览器测试hello world XML网页
打开浏览器并在地址栏中输入：http://127.0.0.1:9000/examples/helloworld.xml，你将会看到如下画面，这当然不是我们所期望的。
3、用web tool来配置服务
3-1.登录到web tool，即在地址栏中输入：http://127.0.0.1:9000/webtool/login.uix，并在下图的用户名及密码中分别输入orcladmin与manager。
3-2.点击下图网页上的Service Designer标签，并点击"Create Master Service"按钮以新建一个主服务。
3-3.在弹出的如下画面中输入HelloWorld_
3-4. 点击上图中的"INIT PARAMETERS"页上的下一步，在弹出的如下画面的URL一行中输入：http://127.0.0.1:9000/walkthrough/helloworld.xml，点击下一步，点击"Asynch Agent"页上的下一步，点击"Result Transformers"页上的完成。
这样就建立了一个主服务，下面接着是建立用户服务。
3-6．点击Content Manager标签，系统弹出如下图所示的画面：
3-7．点击上图中的"Add Service"按钮后，在如下画面的Service Name文本框中输入：HelloiDevelop_＜name＞，点击下一步，点击"Root Folder and Services"中的"Master"文件夹并选中刚建的HelloWorld 主服务，点击下一步，点击"Input Parameters"网页中的下一步，点击提交按钮。

4、用户访问权及服务配置
4-1．点击"Groups"链接为每组用户分配服务，如下图所示：
4-2.选中上图中的"Guests"收音机按钮，并点击"Assign Services"，这样就为每一个无线用户分配了一个无线访问权。然后再将HelloiDevelop服务添加到本组中，如下图示：
5、HelloWord在模拟器上的测试
5-1.双击桌面上名为UP.Simulator，形如移动电话的图标，并在地址栏中输入：http://127.0.0.1:9000/ptg/rm，如下图示：
5-2.选中上图中的helloworld服务，(如下图示：)哇噻，这不正是我们所期望的

正在看的ORACLE教程是:用Oracle9ias开发无线应用程序开发者网络Oracle。helloworld的吗？这只是万里长征中的第一步，如果想用ORACLE9IAS来开发诸如在无线设备上实时股票、航班等信息的应用程序及其他语音应用程序还需要更多的ORACLE9IAS知识。

When should you use a composite index versus multiple single-column indexes?Apr 11, 2025 am 12:06 AMIn database optimization, indexing strategies should be selected according to query requirements: 1. When the query involves multiple columns and the order of conditions is fixed, use composite indexes; 2. When the query involves multiple columns but the order of conditions is not fixed, use multiple single-column indexes. Composite indexes are suitable for optimizing multi-column queries, while single-column indexes are suitable for single-column queries.
How to identify and optimize slow queries in MySQL? (slow query log, performance_schema)Apr 10, 2025 am 09:36 AMTo optimize MySQL slow query, slowquerylog and performance_schema need to be used: 1. Enable slowquerylog and set thresholds to record slow query; 2. Use performance_schema to analyze query execution details, find out performance bottlenecks and optimize.
MySQL and SQL: Essential Skills for DevelopersApr 10, 2025 am 09:30 AMMySQL and SQL are essential skills for developers. 1.MySQL is an open source relational database management system, and SQL is the standard language used to manage and operate databases. 2.MySQL supports multiple storage engines through efficient data storage and retrieval functions, and SQL completes complex data operations through simple statements. 3. Examples of usage include basic queries and advanced queries, such as filtering and sorting by condition. 4. Common errors include syntax errors and performance issues, which can be optimized by checking SQL statements and using EXPLAIN commands. 5. Performance optimization techniques include using indexes, avoiding full table scanning, optimizing JOIN operations and improving code readability.
Describe MySQL asynchronous master-slave replication process.Apr 10, 2025 am 09:30 AMMySQL asynchronous master-slave replication enables data synchronization through binlog, improving read performance and high availability. 1) The master server record changes to binlog; 2) The slave server reads binlog through I/O threads; 3) The server SQL thread applies binlog to synchronize data.
MySQL: Simple Concepts for Easy LearningApr 10, 2025 am 09:29 AMMySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
MySQL: A User-Friendly Introduction to DatabasesApr 10, 2025 am 09:27 AMThe installation and basic operations of MySQL include: 1. Download and install MySQL, set the root user password; 2. Use SQL commands to create databases and tables, such as CREATEDATABASE and CREATETABLE; 3. Execute CRUD operations, use INSERT, SELECT, UPDATE, DELETE commands; 4. Create indexes and stored procedures to optimize performance and implement complex logic. With these steps, you can build and manage MySQL databases from scratch.
How does the InnoDB Buffer Pool work and why is it crucial for performance?Apr 09, 2025 am 12:12 AMInnoDBBufferPool improves the performance of MySQL databases by loading data and index pages into memory. 1) The data page is loaded into the BufferPool to reduce disk I/O. 2) Dirty pages are marked and refreshed to disk regularly. 3) LRU algorithm management data page elimination. 4) The read-out mechanism loads the possible data pages in advance.
MySQL: The Ease of Data Management for BeginnersApr 09, 2025 am 12:07 AMMySQL is suitable for beginners because it is simple to install, powerful and easy to manage data. 1. Simple installation and configuration, suitable for a variety of operating systems. 2. Support basic operations such as creating databases and tables, inserting, querying, updating and deleting data. 3. Provide advanced functions such as JOIN operations and subqueries. 4. Performance can be improved through indexing, query optimization and table partitioning. 5. Support backup, recovery and security measures to ensure data security and consistency.
