1.在PL/SQL的界面,找到Directories文件夾,找到目錄文件的路徑


2.通過SSH進入服務器
找到相應的路徑 cd /u01/oracle/dpdir
輸入指令
df -h 查看資源使用量
su – oracle 進入系統的oracle用戶
3.導出數據庫文件
expdp userid=hbcxjm/oracle directory=dpdir dumpfile=hbcxjm.dmp job_name=hbcxjm logfile=hbcxjmlog parallel=2 schemas=hbcxjm
PS:
其中userid是要導出的目標庫的用戶名密碼,directory是建立的路徑名稱,dumpfile是目標文件名稱
4.新建數據庫用戶
PS:注意表空間問題,確保表空間充足,否則導入會報錯
5.導入數據
impdp hbcxjm/oracle directory=dpdir dumpfile=hbcxjm.dmp REMAP_SCHEMA=hbcxjm:hbcxjm REMAP_TABLESPACE=TP_HBCXJM:TP_HBCXJM
table_exists_action = truncate logfile=hbcxjmimp.log SCHEMAS=hbcxjm
PS:
REMAP_SCHEMA:導出數據用戶的名稱和導入數據用戶的名稱
REMAP_TABLESPACE:導出數據用戶的表空間和導入數據用戶的表空間
table_exists_action:如果表中有數據的處理方式,此處采用truncate處理
logfile:日志文件名稱
例子:
