大多数时候使用的操作系统是Windows系统,对于Liunx的了解就是少之又少了。
这段时间我们在做一个关于影像的系统要求所有的应用都部署在RedHat系统上,这样就有两个软件使用方面的问题:1、数据库 2、应用中间键

我们的数据库使用的是oralce10g

项目组中没有精通Oracle的人,在加上是liunx操作系统,所以更加困难。这种困难引起了两个主要的问题:

a、编码问题,首先我们数据库字符集使用的gbk,,而国家字符集使用的是utf-8的字符集。

我写了一个导数的脚本,将本地文件的数据导入到数据库中,导入完成后查询发现所有的中文字符都是乱码,顿时就晕了。

最后查了一下发现是数据库字符集的问题,之后在数据库所在用户的环境变量中添加了如下环境变量就好了:

export NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK

b、今天修改了一个数据的参数,想重启一下数据库用sys用户登录后用shutdown immediate将数据库关闭

之后再用其startup是就报错了,不知道如何是好试了变天还是不好,最后向人求助才知道需要在环境变量中设置自己要启动的数据库的SID

于是执行了如下命令export ORACLE_SID=sssdb

再重新执行下面命令就好了:

用sqlplus启动数据库

$ORACLE_HOME/bin/sqlplus /nolog
SQL> connect sys/1as sysdba
SQL> startup
启动TNS监听器
$ORACLE_HOME/bin/lsnrctl start

应用中间件我们使用的weblogic10g刚刚装完以后就是丈二和尚摸不着头脑了

上网查了一下就是得先建domain,然后就在$ WEBLOGIC_HOME/wlserver_10.3/common/bin下找到config.sh脚本执行建立了domain

然后就是启动了,在目录$ WEBLOGIC_HOME/user_projects/domains/mydomain/bin下执行startWebLogic.sh就可以了

最后还发生一件诡异的事情,就是修改后的文件不生效。想了一下之前在用websphere6.1的时候就这个问题,就使用find(find ./ -name *)命令查找相关的文件,结果找了几个全部删除后重新发布就ok了。

MySQL's Role: Databases in Web Applications MySQL's Role: Databases in Web Applications Apr 17, 2025 am 12:23 AM

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.

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.

MySQL: An Introduction to the World's Most Popular Database 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.

MySQL's Place: Databases and Programming MySQL's Place: Databases and Programming Apr 13, 2025 am 12:18 AM

MySQL's position in databases and programming is very important. It is an open source relational database management system that is widely used in various application scenarios. 1) MySQL provides efficient data storage, organization and retrieval functions, supporting Web, mobile and enterprise-level systems. 2) It uses a client-server architecture, supports multiple storage engines and index optimization. 3) Basic usages include creating tables and inserting data, and advanced usages involve multi-table JOINs and complex queries. 4) Frequently asked questions such as SQL syntax errors and performance issues can be debugged through the EXPLAIN command and slow query log. 5) Performance optimization methods include rational use of indexes, optimized query and use of caches. Best practices include using transactions and PreparedStatemen

Why Use MySQL? Benefits and Advantages 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.

MySQL vs. Other Programming Languages: A Comparison MySQL vs. Other Programming Languages: A Comparison Apr 19, 2025 am 12:22 AM

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages ​​such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages ​​have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL: From Small Businesses to Large Enterprises MySQL: From Small Businesses to Large Enterprises Apr 13, 2025 am 12:17 AM

MySQL is suitable for small and large enterprises. 1) Small businesses can use MySQL for basic data management, such as storing customer information. 2) Large enterprises can use MySQL to process massive data and complex business logic to optimize query performance and transaction processing.

How does MySQL index cardinality affect query performance? How does MySQL index cardinality affect query performance? Apr 14, 2025 am 12:18 AM

MySQL index cardinality has a significant impact on query performance: 1. High cardinality index can more effectively narrow the data range and improve query efficiency; 2. Low cardinality index may lead to full table scanning and reduce query performance; 3. In joint index, high cardinality sequences should be placed in front to optimize query.
