1:导出语句
连接数据库应用 执行下列脚本
expdp PORTAL/PORTAL dumpfile=PORTAL20141023.dmp
logfile
=PORTAL.log schemas=PORTAL
2:查看dump 默认导出目录 用FTP提取
select
*
from
all_directories;
2、Create 同义词
create
or
replace
synonym
SYN_EMERGENCY_INFO
3、表空间使用情况查看
SELECT
D.TABLESPACE_NAME "表空间名字", D.STATUS "状态",
(A.BYTES /
1024
/
1024
)
as
"总共多少M",
((A.BYTES -
DECODE
(F.BYTES,
NULL
,
0
, F.BYTES)) /
1024
/
1024
)
as
"已经用了多少M",
(
DECODE
(F.BYTES,
NULL
,
0
, F.BYTES) /
1024
/
1024
)
as
"剩余多少M",
((A.BYTES -
DECODE
(F.BYTES,
NULL
,
0
, F.BYTES)) /
1024
/
1024
)/(A.BYTES /
1024
/
1024
)
as
"利用率",
DECODE
(
sign
(((A.BYTES -
DECODE
(F.BYTES,
NULL
,
0
, F.BYTES)) /
1024
/
1024
)/(A.BYTES /
1024
/
1024
)-
0.9
),
1
,
'剩余不到10%,请考虑扩表空间'
,
'正常'
)
as
"温馨提示"
FROM
SYS.DBA_TABLESPACES D, SYS.SM$TS_AVAIL A, SYS.SM$TS_FREE F
WHERE
D.TABLESPACE_NAME = A.TABLESPACE_NAME
AND
F.TABLESPACE_NAME (+) = D.TABLESPACE_NAME
