orcle相关命令收集
1，用管理员登陆
/as sysdba；
2, 更改用户密码
alter user name identified by password；
alter user exptest identified by exptest;
查询用户名：
select username,password from dba_users;
3，连接用户名

alter user accf default tablespace oa_data;
alter user accf quota unlimited on oa_data;
grant create session to accf;
grant create table to accf;
grant create tablespace to accf;
grant create view to accf;
grant alter tablespace to accf;
grant dba to accf;
grant select ,insert(sno,cno),update on sscc to coco--为用户对象付特权
4.2创建用户给默认表空间

create tablespace OA_DATA datafile 'D: oa_data.dbf' size 50m autoextend on
next 50m maxsize 512m extent management local;
4.3为用户指定表空间

6，修改用户默认表空间
alter user coco default tablespace oatest;
7，查询用户自己所在的表空间
select username,default_tablespace from user_users;
8, 查询数据库的sid
show parameter instance_name;
9，查看sid
select instance_name from v$instance;
10，判断连接
telnet 127.0.0.1 1521
ping 10.132.21.18
11，登陆远程sql plus
conn exptest/cc@10.132.21.18/oatest;
//10.132.21.18:1521:oatest
12, 创建数据库之间的连接dblink
create database link linkexp
connect to exptest identified by D33gw1TYs
using '(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.132.21.18)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = oatest)
)
)';
13，删除dblink
Drop public DATABASE LINK linkme;
Drop DATABASE LINK linkme;
14，tnsnames.ora配置
D:appAdministratorproduct11.2.0client_1
etworkadmin nsnames.ora,
# tnsnames.ora Network Configuration File: D:appAdministratorproduct11.2.0dbhome_2NETWORKADMIN nsnames.ora
# Generated by Oracle configuration tools.
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SID = orcl)
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
15，oracle卸载
运行regedit，删除HKEY_LOCAL_MACHINESOFTWAREORACLE
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServices，滚动 这个列表，删除所有Oracle入口。
HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesEventlogApplication， 删除所有Oracle入口。
16, 管理员权限
grant dba to coco;
--Revoke dba from coco;
17, 迁移数据库
当本地用户名与服务器端不一致时，需要在本地建立一个相同的用户
17.1导入数据库
@d:/EE.sql
PL/SQL中直接写@
18, 查看用户空间下所有的表
-- connect xx/xx 切换到这个用户
select * from tab;
19，共享命令，安装12c时用到：net share nu=c: /grant:everyone,full
20，导出命令exp coco/coco@orcl file=d:exp.dmp full=y;
exp exptest/exptest@localhost:1521/orcl file=d:exp.dmp full=y;
exp exptest/D33gw1TYs@10.132.21.18/oatest file=d:exp.dmp;
exp oapre/Cq#1988@10.132.21.18/oapre file=d:oapre.dmp;
url="jdbc:oracle:thin:@10.132.21.18:1521:oapre"
username="oapre"
password="Cq#1988"
imp accf/accf file=uat.dmp fromuser=oapre touser=accf tablespaces=users;
imp coco/coco file=uat.dmp fromuser=oapre touser=accf tablespaces=users;
20.1、导出指定表：exp 用户名/密码@数据库名 file=c:filename.dmp tables=(table1,table2).
必须在括号中列出所有表名。
20.2、导出特定用户所有表：exp 用户名/密码@数据库名 file=c:filename.dmp owner=用户名
21，查询有clob字段的表
select distinct('TABLE "'||a.OWNER ||'"."'||a.TABLE_NAME||'"') from sys.all_tab_columns a
where a.OWNER = 'EXPTEST' and a.TABLE_NAME not in (
select t.TABLE_NAME from sys.all_tab_columns t
where t.OWNER = 'EXPTEST' and t.DATA_TYPE in ('CLOB','BLOB')
);
22，误操作
22.1删除之前闪回
flashback table AA to before drop;
22.2指定时间之前闪回
alter table AA enable row movement;
flashback table AA to timestamp to_timestamp('2016-02-18 10:25:21','yyyy-mm-dd hh24:mi:ss');
22.3通过查询闪回
select * from AA as of timestamp TO_TIMESTAMP('2016-02-19 13:36:05', 'yyyy-mm-dd hh24:mi:ss');
