非Oracle用户使用操作系统验证登陆(/ as sysdba)
之前写过一篇blog《新用户使用sqlplus / as sysdba登录报错》http://blog.csdn.net/bisal/article/details/9285087 今天碰巧看到一篇推荐的帖子《新建一个用户(非oracle),在不赋予dba所属组的情况下,不能使用操作系统验证》 http://www.itpub.net/thread

今天碰巧看到一篇推荐的帖子《新建一个用户(非oracle),在不赋予dba所属组的情况下,不能使用操作系统验证》
http://www.itpub.net/thread-1811278-1-1.html,也是按照实际操作的流程解释了处理的方法,很实际。
总结起来,使用非oracle用操作系统验证登录,需要做的:
1、设置相关环境变量;
2、将用户添加到dba组中;
3、用户具有$ORACLE_HOME相关路径(尤其是bin)文件的执行权限。
但上次调试一个测试库,创建非Oracle安装用户时也试了如上方法,但未奏效,肯定哪里还有点问题,找个时间再看看了要。

结论:oracle之外的用户,在打开了操作系统验证的情况下,还需要加入dba组才能使用操作系统验证

Linux is suitable for servers, development environments, and embedded systems. 1. As a server operating system, Linux is stable and efficient, and is often used to deploy high-concurrency applications. 2. As a development environment, Linux provides efficient command line tools and package management systems to improve development efficiency. 3. In embedded systems, Linux is lightweight and customizable, suitable for environments with limited resources.

SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

Triggers in Oracle are stored procedures used to automatically perform operations after a specific event (insert, update, or delete). They are used in a variety of scenarios, including data verification, auditing, and data maintenance. When creating a trigger, you need to specify the trigger name, association table, trigger event, and trigger time. There are two types of triggers: the BEFORE trigger is fired before the operation, and the AFTER trigger is fired after the operation. For example, the BEFORE INSERT trigger ensures that the age column of the inserted row is not negative.

Zookeeper performance tuning on CentOS can start from multiple aspects, including hardware configuration, operating system optimization, configuration parameter adjustment, monitoring and maintenance, etc. Here are some specific tuning methods: SSD is recommended for hardware configuration: Since Zookeeper's data is written to disk, it is highly recommended to use SSD to improve I/O performance. Enough memory: Allocate enough memory resources to Zookeeper to avoid frequent disk read and write. Multi-core CPU: Use multi-core CPU to ensure that Zookeeper can process it in parallel.

To stop an Oracle database, perform the following steps: 1. Connect to the database; 2. Shutdown immediately; 3. Shutdown abort completely.

The macOS operating system was invented by Apple. Its predecessor, System Software, was launched in 1984. After many iterations, it was updated to Mac OS X in 2001 and changed its name to macOS in 2012.

Two ways to rename Oracle table names: use SQL statements: ALTER TABLE <Old table name> RENAME TO <New table name>;Use PL/SQL statements: EXECUTE IMMEDIATE 'ALTER TABLE ' || :old_table_name || ' RENAME TO ' || :new_table_name;
