一次數(shù)據(jù)導(dǎo)入過程

一。查出原系統(tǒng)有多少表空間：

select a.tablespace_name,total,free,round(free/total*100,2) free_precent,total-free used from
( select tablespace_name,sum(bytes)/1024/1024 total from dba_data_files
group by tablespace_name) a,
( select tablespace_name,sum(bytes)/1024/1024 free from dba_free_space
group by tablespace_name) b
where a.tablespace_name=b.tablespace_name
order by tablespace_name;

三.根據(jù)以上文件分別建立表空間
1.先擴(kuò)大本身的user01.dbf的空間

SQL>alter database datafile '/opt/oracle/oradata/orcl/users01.dbf' resize 30G;
2.再增加數(shù)據(jù)文件

SQL>alter tablespace users add datafile '/opt/oracle/oradata/orcl/users02.dbf' size 30G;

SQL>alter tablespace users add datafile '/opt/oracle/oradata/orcl/users03.dbf' size 30G;

3.創(chuàng)建索引表空間
SQL>create tablespace INDX datafile '/opt/oracle/oradata/orcl/indx01.dbf' size 30G;
SQL>alter tablespace INDX add datafile '/opt/oracle/oradata/orcl/indx02.dbf' size 30G;

SQL>alter tablespace INDX add datafile '/opt/oracle/oradata/orcl/indx03.dbf' size 30G;
其它表空間

create tablespace DBA01_2001 datafile '/opt/oracle/oradata/orcl/users_2001.dbf' size 500M;
create tablespace DBA01_2002 datafile '/opt/oracle/oradata/orcl/users_2002.dbf' size 500M;
create tablespace DBA01_2003 datafile '/opt/oracle/oradata/orcl/users_2003.dbf' size 500M;
create tablespace DBA01_2004 datafile '/opt/oracle/oradata/orcl/users_2004.dbf' size 500M;
create tablespace DBA01_2005 datafile '/opt/oracle/oradata/orcl/users_2005.dbf' size 500M;
create tablespace DBA01_2006 datafile '/opt/oracle/oradata/orcl/users_2006.dbf' size 500M;
create tablespace DBA01_2007 datafile '/opt/oracle/oradata/orcl/users_2007.dbf' size 500M;
create tablespace DBA01_2008 datafile '/opt/oracle/oradata/orcl/users_2008.dbf' size 500M;
create tablespace DBA01_2009 datafile '/opt/oracle/oradata/orcl/users_2009.dbf' size 500M;
create tablespace DBA01_2010 datafile '/opt/oracle/oradata/orcl/users_2010.dbf' size 500M;
create tablespace DBA01_2011 datafile '/opt/oracle/oradata/orcl/users_2011.dbf' size 500M;

建立目錄：以SYS管理登錄
sql> create directory expdir as '/opt/oracle/oradata/orcl';
一。授權(quán)用戶
sql> grant EXP_FULL_DATABASE to orauser
sql> grant IMP_FULL_DATABASE to orauser

注意：
針對大數(shù)據(jù)庫導(dǎo)入時，遇到了由于db_recovery_file_dest_size=4G (太小)，導(dǎo)致不能寫日志，導(dǎo)入過程停在那里了。
通過
SQL> alter system set db_recovery_file_dest_size =50G scope=both來設(shè)置。--調(diào)大

在linux命令窗口以 oracle用戶登錄
導(dǎo)入

# impdp orauser/password directory=expdir dumpfile=data.dmp logfile=exp.log full=y

#單張表。如果表已經(jīng)存在則要先刪除
  impdp 用戶名/密碼 TABLES= DIRECTORY=expdir  DUMPFILE=data.dmp

導(dǎo)出：
# expdp orauser/password directory=expdir compression=ALL dumpfile=data.dmp full=y logfile=exp.log
