Oracle 添加用户并赋权,修改密码,解锁,删除用户实现方法,需要的朋友可以参考下。

添加用户(随着用户的创建,自动产生与用户同名的schema)
CREATE USER "TESTER" PROFILE "DEFAULT" IDENTIFIED BY "TESTER" DEFAULT TABLESPACE "TESTDATA" TEMPORARY TABLESPACE "TESTTEMP" ACCOUNT UNLOCK;
赋权(说实话,这些权限是开发中使用的权限,如果用户生产环境,请自行对于用户创建相应的系统权限)
据说生产环境下,只是connect resource这样的角色就可以了。
GRANT "CONNECT" TO "TESTER";
GRANT "RESOURCE" TO "TESTER";
GRANT "DBA" TO "TESTER";
GRANT "EXP_FULL_DATABASE" TO "TESTER";
GRANT "IMP_FULL_DATABASE" TO "TESTER";
删除用户:例如创建了一个用户 A,要删除它可以这样做
connect sys/密码 as sysdba;
drop user A cascade;//就这样用户就被删除了
用户修改密码,解锁
ALTER USER "SCOTT" IDENTIFIED BY "*******"
ALTER USER "SCOTT" ACCOUNT UNLOCK
1.查看所有用户:
select * from dba_user;
select * from all_users;
select * from user_users;
2.查看用户系统权限:
select * from dba_sys_privs;
select * from all_sys_privs;
select * from user_sys_privs;
3.查看用户对象权限:
select * from dba_tab_privs;
select * from all_tab_privs;
select * from user_tab_privs;
4.查看所有角色:
select * from dba_roles;
5.查看用户所拥有的角色:
select * from dba_role_privs;
select * from user_role_privs;
Oracle中新建用户名
连接ORACLE数据库:
1、在Oracle Database Assistant中建立自己的数据库;
2、在Oracle Net8 Easy config中建立连接与自己的数据库的连接,取一个service名,IP:为本地IP 127.0.0.1,database sid为你所建立的
数据库的SID,用户名为:system,密码:manager或是自己设的密码;
3、在SQLPLUS中连接自己的数据库,用户名为:system,密码:manager或是自己设的密码,tom:你刚建立的service名.
4、显示当前连接用户:show user;
5、新建用户并授权:sql>create user tom identified by 密码;
sql> grant connect,resource to tom;//授权
注:授权还有:create any procedure,select any dictionary(登陆oem需要),select any table等.
6、在sqlplus中用刚建立的用户:tom/密码,连接;
7、建立表空间。
数据库的初始化参数文件:init+实例名.ora文件,编辑此文件中的内容,可以改变数据库使用的方法和分配的资源.
启动ORACLE数据库,在DOS方式下运行svrmgr30,然后输入connect internal,密码为:oracle,再输入startup即可.
表空间的建立:storage manager
回滚段可在storage manager中建立
启动oracle数据库
在DOS窗口下,输入svrmgr30,启动服务器管理器,输入connect internal,输入密码oracle,输入shutdown,关闭数据库,输入startup,启动数据库.
1. Oracle安装完成后的初始口令?10g以后安装的时候选高级,密码都可以自己设置,呵呵,scott/tiger是不变的。
   internal/oracle
   sys/change_on_install
   system/manager
   scott/tiger
   sysman/oem_temp
建立表空间
create tablespace test1 datafile 'd:tabletest1.dbf' size 1M;
创建名为wjq的用户,其缺省表空间为test1。在SQL*PLUS以SYS用户连接数据库,运行以下脚本。
create user wjq identified by password default tablespace test1;
以用户wjq连接sqlplus
建立表:CREATE TABLE t1(empno NUMBER(5) PRIMARY KEY, ename VARCHAR2(15) NOT NULL, job VARCHAR2(10), mgr NUMBER(5),hiredate
DATE DEFAULT (sysdate), sal NUMBER(7,2), comm NUMBER(7,2));
建立表T2并指定此表的表空间为test1:CREATE TABLE t2(empno NUMBER(5) PRIMARY KEY,ename VARCHAR2(15) NOT NULL,
job VARCHAR2(10),mgr NUMBER(5),hiredate DATE DEFAULT (sysdate),sal NUMBER(7,2),comm NUMBER(7,2)) TABLESPACE test1;
插入记录:insert into t1 values(101,'wang','it',25,'',20,20);

Explain the InnoDB Buffer Pool and its importance for performance.Explain the InnoDB Buffer Pool and its importance for performance.Apr 19, 2025 am 12:24 AM

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.
