2.epras导入

=============================================

root@t2000 # su - oracle

Sun Microsystems Inc. SunOS 5.10 Generic January 2005

$ sqlplus /nolog

SQL> conn / as sysdba

Connected.

SQL> ho

复制数据文件，此时数据库ltdb的tsts表空间还是read only

$ cp /tmp/LTDB/TS*DBF /oracle

建立目标数据库上的用户，如果不建立，导入时需要加touser=参数，否则会出错

SQL> create user ts identified by ts;

User created.

SQL> ho

SQL> revoke connect from ts;

Revoke succeeded.

SQL> revoke resource from ts;

Revoke succeeded.

SQL> ho
