expdp 表空间复制
--1.newwork_link为目标数据库建立的database_link,(用户test 需要grant exp_full_database to TEST; )
create public database link tolink
connect to TEST identified by oracle
using '(description =
(address_list =
(address = (protocol = tcp)(host = 10.0.20.199)(port = 1521))
)
(connect_data =
(service_name = orcl)
)
)';
--2.impdp在目标数据库服务器上执行 只能低版本向高版本imp
impdp network_link=tolink schemas=test remap_schema=test:link2
各位看看有什么问题吗?我怎么没复制成功啊?是不是执行有问题?
