--修改通过PL/SQL创建的用户

C:\Users\User>sqlplus test/123456@orcl as sysdba

SQL> alter user test0918 identified by test0918;

--==数据库导入导出==--

C:\Users\User>sqlplus system/test0506@orcl92 as sysdba

drop tablespace test_data including contents and datafiles;//删除表空间,同时删除数据文件:

SQL> create tablespace CFFGLOANSPACE datafile 'F:\oracle12\oracle12Data\CFFGLOANSPACE.dbf' size 600m autoextend on next 30m MAXSIZE UNLIMITED;

DROP TABLESPACE cffgloanspace INCLUDING CONTENTS AND DATAFILES;//删除表空间

SQL> create user test0902 identified by test0506 default tablespace cffg92;

SQL> grant dba to test0902;

SQL> imp test0902/test0506@orcl92 file=F:\2015-9-2.dmp full=y;

--导入数据库  imp username/password@[ip/]oracle数据库实例名 file=路径\xx.dmp [full=y]; 当full=y时如果要忽略警告信息可以加上 ignore=y

sql>imp clsuser/cls@orcl file=e:\p2p.dmp full=y;

C:\Users\User>imp test0903/test0506@orcl file=F:\2015-9-2.dmp fromuser=clspuser touser=test0903  老大

sql>imp xxfbgswl/xxfbgswl@zbx25  file=e:\gswl20130424.dmp  fromuser=gswl touser=xxfbgswl log=e:xxfblog.log  rows=y --导出数据库  

C:\Users\User>imp hbus\hbus@hbus file=F:\test0506.dmp fromuser=test0506 touser=hbus ignore=y

导出dmp命令:【非本地数据库在@后添加ip/】exp username/password@oracle数据库实例名 file=存放导出路径\XXX.dmp(如file=E:\导入导出\export.dmp)

sql>exp gswleq/gswleq@dlzbx file=D:\gswl0619.dmp log=gswl.log owner=(gswleq) rows=y;

sql>exp gswleq/gswleq@dlzbx file=D:\gswl0619.dmp full=y;

//导出指定用户的

exp gswleq/gswleq@dlzbx file=D:\gswl0619.dmp owner=gswleq;
