64位Oracle客户端上PLSQL无法识别ORACLE_HOME解决方案
PLSQL到目前为止只有32位的程序,而大多数的桌面系统基本都是使用64位的Windows操作系统,在64位的Windows上,大多数情况下也是安
1、问题
PLSQL到目前为止只有32位的程序,而大多数的桌面系统基本都是使用64位的Windows操作系统,在64位的Windows上,大多数情况下也是安装64位的Oracle client程序,这种组合,导致plsql无法识别到ORACLE_HOME目录,读取不到tnsnames.ora文件中的连接串
2、解决方案
2.1 在Windows上配置ORACLE_HOME环境变量
右击“我的电脑”点击”属性“菜单,进入”系统属性“对话框,选择”高级“标签,点击“环境变量”,在用户变量框区域,新建一个名为‘ORACLE_HOME的变量名,根据自己的ORACLE实际安装目录填写其值,例如,笔者的环境的ORACLE_HOME的值为” C:\oracle\product\12.1.0\dbhome_1”
2.2 引用instantclient-basic-win32-10.2.0.5
将instantclient-basic-win32-10.2.0.5.zip文件解压,压缩后的文件,复制到PLSQL Developer安装目录的product目下,如C:\oracle\product\,最终instantclient的目录为C:\oracle\product\C:\oracle\product\instantclient-basic-win32-10.2.0.5\instantclient_10_2
instantclient-basic-win32-10.2.0.5.zip文件,笔者已上传到“系统性能优化专业群”群共享中供各位下载。
2.3 在PLSQL中配置ORACLE_HOME与OCI库
2.3.1 配置ORACLE_HOME
在PLSQL主菜单上点击Tools,选择Preferences子菜单,进入“首选页”对话框,在“连接”选项卡的右侧,找到“Oracle主目录名(自动检测为空)”,在该框中填写ORACLE的HOME目录名,如:“C:\oracle\product\12.1.0\dbhome_1”
2.3.2 配置OCI库
在PLSQL主菜单上点击Tools,,选择Preferences子菜单,进入“首选页”对话框,在“连接”选项卡的右侧,找到“OCI库(自动检测为空)”,在该框中填写oci.dll文件的绝对路径,如:“C:\oracle\product\instantclient-basic-win32-10.2.0.5\instantclient_10_2\oci.dll”
3、结果
上述四步配置完成后,重启PLSQL,就可以识别ORACLE_HOME,并能找到ORACLE客户端tnsnames.ora文件中的数据库连接串了。
Oracle 10g 安装后重启系统,用PLSQL连接报没有监听
ORA-03114 PLSQL过程编译断开连接错误

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 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 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

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.

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 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.

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.
