1.在PL/SQL的界面,找到Directories文件夹,找到目录文件的路径
2.通过SSH进入服务器
找到相应的路径 cd /u01/oracle/dpdir
输入指令
df -h 查看资源使用量
su – oracle 进入系统的oracle用户
3.导出数据库文件
expdp userid=hbcxjm/oracle directory=dpdir dumpfile=hbcxjm.dmp job_name=hbcxjm logfile=hbcxjmlog parallel=2 schemas=hbcxjm
PS:
其中userid是要导出的目标库的用户名密码,directory是建立的路径名称,dumpfile是目标文件名称
4.新建数据库用户
PS:注意表空间问题,确保表空间充足,否则导入会报错
5.导入数据
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:导出数据用户的名称和导入数据用户的名称
REMAP_TABLESPACE:导出数据用户的表空间和导入数据用户的表空间
table_exists_action:如果表中有数据的处理方式,此处采用truncate处理
logfile:日志文件名称
