------- 权限管理:对象撤销授权
grant select mytable to leap2
grant all on mytable to leap2
-----权限管理:权限的传递
---不可以权限传递
grant alter any table to leap2 ---把修改表结构的权限授权给leap2,
并且leap2 不可以把此权限授权给其他的用户leap3
---可以权限传递
grant alter any table to leap2 with admin option ---把修改表结构的权限授权给leap2,
并且leap2 可以把此权限授权给其他的用户leap3
-----把表的查询权限授权给其他用户 不能传递
grant select on mytable to leap2 ---把查询表的权限授权给leap2,
并且leap2 不可以把此权限授权给其他的用户leap3
---把表的查询权限授权给其他用户 能传递
grant select on mytable to leap2 with grant option---把查询表的权限授权给leap2,
并且leap2 可以把此权限授权给其他的用户leap3
----角色 角色就是权限的集合 可以把一个角色授予给用户
---创建角色
create role myrole
---删除角色
drop myrole
--角色是权限的集合,所以要把权限放进角色内。
grant create session to myrole
grant create table to myrole
---授权角色给用户
grant myrole to leap
注意: 有些权限不能授权给角色
例如 unlimited tablespace
表示属于创建它的用户的
角色不是属于任意一个用户 是所有用户公用的
---限制用户
alter User 用户名 Account Lock---- 用户加锁
alter User 用户名 Account unLock---- 用户解锁
alter User 用户名 Password expire---- 用户密码即可失效
---删除用户
drop User 用户名--- 用户下面每有对象
drop User 用户名 cascade ----用户下面有表或者对象必须用cascade
cascade 表示强制删除用户所有对象
----命令下启动oracle listener
lsnrctl start [listenerName] --启动
lsnrctl stop [listenerName] --关闭
希望这张列表,能够对Oracle系统管理员们给予一定的帮助。

It allows users to perform more in-depth operations and customization of the system. Root permission is an administrator permission in the Android system. Obtaining root privileges usually requires a series of tedious steps, which may not be very friendly to ordinary users, however. By enabling root permissions with one click, this article will introduce a simple and effective method to help users easily obtain system permissions. Understand the importance and risks of root permissions and have greater freedom. Root permissions allow users to fully control the mobile phone system. Strengthen security controls, customize themes, and users can delete pre-installed applications. For example, accidentally deleting system files causing system crashes, excessive use of root privileges, and inadvertent installation of malware are also risky, however. Before using root privileges

The retention period of Oracle database logs depends on the log type and configuration, including: Redo logs: determined by the maximum size configured with the "LOG_ARCHIVE_DEST" parameter. Archived redo logs: Determined by the maximum size configured by the "DB_RECOVERY_FILE_DEST_SIZE" parameter. Online redo logs: not archived, lost when the database is restarted, and the retention period is consistent with the instance running time. Audit log: Configured by the "AUDIT_TRAIL" parameter, retained for 30 days by default.

The function in Oracle to calculate the number of days between two dates is DATEDIFF(). The specific usage is as follows: Specify the time interval unit: interval (such as day, month, year) Specify two date values: date1 and date2DATEDIFF(interval, date1, date2) Return the difference in days

The Oracle database startup sequence is: 1. Check the preconditions; 2. Start the listener; 3. Start the database instance; 4. Wait for the database to open; 5. Connect to the database; 6. Verify the database status; 7. Enable the service (if necessary ); 8. Test the connection.

The amount of memory required by Oracle depends on database size, activity level, and required performance level: for storing data buffers, index buffers, executing SQL statements, and managing the data dictionary cache. The exact amount is affected by database size, activity level, and required performance level. Best practices include setting the appropriate SGA size, sizing SGA components, using AMM, and monitoring memory usage.

The INTERVAL data type in Oracle is used to represent time intervals. The syntax is INTERVAL <precision> <unit>. You can use addition, subtraction, multiplication and division operations to operate INTERVAL, which is suitable for scenarios such as storing time data and calculating date differences.

To find the number of occurrences of a character in Oracle, perform the following steps: Get the total length of a string; Get the length of the substring in which a character occurs; Count the number of occurrences of a character by subtracting the substring length from the total length.

Oracle database server hardware configuration requirements: Processor: multi-core, with a main frequency of at least 2.5 GHz. For large databases, 32 cores or more are recommended. Memory: At least 8GB for small databases, 16-64GB for medium sizes, up to 512GB or more for large databases or heavy workloads. Storage: SSD or NVMe disks, RAID arrays for redundancy and performance. Network: High-speed network (10GbE or higher), dedicated network card, low-latency network. Others: Stable power supply, redundant components, compatible operating system and software, heat dissipation and cooling system.
