Oracle11g数据泵导入导出

1、建立directory
mkdir /oradump
chmod -R 777 /oradump
 chown -R oracle.oinstall /oradump


2、建立对象
SQL> create directory dump_dir as '/oradump';            -----在数据库中创建该目录的对象信息。


3、授予读写权限
SQL> Grant read,write on directory dump_dir to user;


4、查询目录
SQL> select owner,directory_name,directory_path from dba_directories;
DIRECTORY_NAME                 DIRECTORY_PATH
------------------------------ --------------------------------------------------------------------------------
DUMP_DIR                       /oradump
EXPNC_DIR                      E:\ncdatabak
DMPDIR                         c:\oracle\dump\
DATA_PUMP_DIR                  /u2/oracle/admin/topprod/dpdump/
ORACLE_OCM_CONFIG_DIR          /u2/oracle/product/11.2.0/dbhome_1/ccr/state


5、按schema导出
C:\Users\Administrator>expdp xxx/xxx@xxxdirectory=dump_dir dumpfile=fullba
k.dmp  logfile=fullbak.log schemas=XXX


6、查看导出文件
cd /oradump
 ls -l
total 317700
-rw-r----- 1 oracle oinstall 325144576 Aug  7 15:33 fullbak.dmp
-rw-r--r-- 1 oracle oinstall    173366 Aug  7 15:33 fullbak.log


7、创建用户grant session synonym view tablespace 等权限
create user XXXidentified by XXX
  default tablespace XXX
  temporary tablespace TEMP
  profile TIPTOPGP;

8、授予新建用户读写directory权限
SQL> Grant read,write on directory dump_dir to XXX;
Grant succeeded


9、按schemas导入table_exists_action参数replace：替换，append：追加数据
C:\Users\Administrator>impdp XXX/XXX@tiptop tables=XXX.aaa_file dumpfile=
aa_file.dmp logfile=aaa.log directory=dump_dir table_exists_action=replace


linux之间文件传输：
1、查看防火墙是否关闭
 /etc/init.d/iptables status
iptables: Firewall is not running.


2、把远程服务器192.168.XXX.XX的/oradump/wxjxt.log拷贝到本地/oradump
 scp [email protected]:/oradump/wxjxt.log /oradump



3把本地/oradump/wxjxt.dmp拷贝到远程192.168.XXX.XX服务器root用户下的/oradump下
 scp /oradump/wxjxt.dmp [email protected]:/oradump
