Oracle创建用户、表空间、导入导出等

1、创建用户与表空间

1)创建表空间

CREATE TABLESPACE test
LOGGING
DATAFILE ’E:\oradata\test.DBF’
SIZE 32M
AUTOEXTEND ON
NEXT 1M
EXTENT MANAGEMENT LOCAL;

CREATE TABLESPACE test
LOGGING
DATAFILE 'E:\oradata\test.DBF' 
SIZE 32M 
AUTOEXTEND ON 
NEXT 1M 
EXTENT MANAGEMENT LOCAL;

2）创建用户并指定表空间

CREATE USER test IDENTIFIED BY test
DEFAULT TABLESPACE test
TEMPORARY TABLESPACE TEMP;

CREATE USER test IDENTIFIED BY test
DEFAULT TABLESPACE test
TEMPORARY TABLESPACE TEMP;

3）给用户授权DBA权限

GRANT connect,dba TO test;

GRANT connect,dba TO test;

4）给用户授权，可以创建DBLINK

GRANT create database link to test;

GRANT create database link to test;

2、删除用户和表空间

1)删除用户和用户相关的数据

drop user test cascade;

drop user test cascade;

2)删除表空间和相应文件

drop tablespace test including contents and datafiles;

drop tablespace test including contents and datafiles;

3、imp/exp导入导出

1)imp导入

imp test/test@ORCL file=F:\数据库备份\broker[2015-06-26].dmp   fromuser=sirm touser=yh_test log=F:\数据库备份\broker[2015-06-26]_imp.log ignore=y

imp test/test@ORCL file=F:\数据库备份\broker[2015-06-26].dmp   fromuser=sirm touser=yh_test log=F:\数据库备份\broker[2015-06-26]_imp.log ignore=y

2)exp导出

exp test/test@RTJJ file=F:\数据库备份\2015-07-10.dmp tables=(RT_OUTGOINGREQUEST,RT_TRADESURVEYLOG,RT_TRADESURVEYLOGDOC) log=F:\数据库备份\2015-07-10.log

exp test/test@RTJJ file=F:\数据库备份\2015-07-10.dmp tables=(RT_OUTGOINGREQUEST,RT_TRADESURVEYLOG,RT_TRADESURVEYLOGDOC) log=F:\数据库备份\2015-07-10.log

4、impdp/expdp导入导出

该方案可以解决oracle高版本导出数据库数据，低版本Oracle无法导入的bug，通过导出的时候指定版本号解决

1)创建directory

CREATE OR REPLACE DIRECTORY dmpdir AS ‘E:\公司资料\数据备份’;
GRANT read, write ON DIRECTORY dmpdir TO test;

CREATE OR REPLACE DIRECTORY dmpdir AS 'E:\公司资料\数据备份';
GRANT read, write ON DIRECTORY dmpdir TO test;

2)远程导出/导入

使新创建的用户test登录并创建数据库连接DBLINK：

sqlplus test/test as sysdba;
create public database link dlink_test connect to test identified by test  using ‘test’; – using ‘test’中，test是远程服务名，是在Net Manager配置的服务命名，也可以使用127.0.0.1/orcl

sqlplus test/test as sysdba;
create public database link dlink_test connect to test identified by test  using 'test'; -- using 'test'中，test是远程服务名，是在Net Manager配置的服务命名，也可以使用127.0.0.1/orcl

远程导出：

EXPDP test/test DIRECTORY=dmpdir NETWORK_LINK=dlink_test
DUMPFILE=test.dmp SCHEMAS=test LOGFILE=test_expdp.log version=10.2.0.4.0

EXPDP test/test DIRECTORY=dmpdir NETWORK_LINK=dlink_test  
DUMPFILE=test.dmp SCHEMAS=test LOGFILE=test_expdp.log version=10.2.0.4.0 

远程导入：

impdp test/test DIRECTORY=dmpdir NETWORK_LINK=dlink_test  SCHEMAS=test
remap_schema=test2:test remap_tablespace=test2:test table_exists_action=REPLACE LOGFILE=test_import.log

impdp test/test DIRECTORY=dmpdir NETWORK_LINK=dlink_test  SCHEMAS=test 
remap_schema=test2:test remap_tablespace=test2:test table_exists_action=REPLACE LOGFILE=test_import.log

3)本地导出/导入

本地导出：

EXPDP test/test@orcl DIRECTORY=dmpdir   DUMPFILE=test.dmp SCHEMAS=test LOGFILE=test_expdp.log  version=10.2.0.4.0

EXPDP test/test@orcl DIRECTORY=dmpdir   DUMPFILE=test.dmp SCHEMAS=test LOGFILE=test_expdp.log  version=10.2.0.4.0

本地导入：

impdp test/test@orcl DIRECTORY=dmpdir DUMPFILE=test2.dmp  SCHEMAS=test
remap_schema=test2:test  remap_tablespace=test2:test table_exists_action=REPLACE LOGFILE=test2_import.log

impdp test/test@orcl DIRECTORY=dmpdir DUMPFILE=test2.dmp  SCHEMAS=test 
remap_schema=test2:test  remap_tablespace=test2:test table_exists_action=REPLACE LOGFILE=test2_import.log

5、查看所有的DIRECTORY 目录

select * from dba_directories;

select * from dba_directories;
