oracle 创建数据库

查询表空间的命令

select t1.name,t2.name

from v $tablespace t1,v$ datafile t2

where t1.ts# = t2.ts#;

CREATE TABLESPACE ORM_342_BETA

DATAFILE '/app/oracle/oradata/sysware/ORM_342_BETA.DBF' size 800M --存储地址初始大小800M

autoextend on next 50M maxsize unlimited --每次扩展10M，无限制扩展

EXTENT MANAGEMENT LOCAL autoallocate SEGMENT SPACE MANAGEMENT AUTO;

CREATE TABLESPACE SYSWARE_ORM_340_UPGRADE

DATAFILE '/app/oracle/oradata/sysware/SYSWARE_ORM_340_UPGRADE.DBF' size 800M

autoextend on next 50M maxsize unlimited

EXTENT MANAGEMENT LOCAL autoallocate SEGMENT SPACE MANAGEMENT AUTO;

1.切换oracle用户：

su - oracle

2.进入sql

sqlplus sys/sysware@sysware as sysdba

3.创建权限目录，用sysdba登陆，在sql窗口执行(或者cmd窗口执行：sqlplus /@sysware（在那个数据库实例中） as sysdba)

create directory 授权目录名 as '授权目录';

grant read,write on directory 授权目录名 to 数据库用户名;

如：

create directory DPDIROEM20230414 as '/syswareIDP/dpdir/DPDIROEM20230414';

grant read,write on directory DPDIROEM20230414 to SYSWARE_ORM_340_UPGRADE;

create directory dpdir1201 as '/syswareIDP/dpdir/dpdir1201';

grant read,write on directory dpdir1201 to SYSWARE_ORM_MR;

4.导入，在cmd窗口执行

impdp 数据库用户名/数据库密码 directory=授权目录名 remap_tablespace=导出数据库的表空间:表空间 dumpfile=数据文件名称.dmp remap_schema=导出数据库的用户名:数据库用户名 transform=OID:N

如：

impdp IDP_20200612/IDP_20200612@sysware directory=dpdir220200612 remap_tablespace=idp_20170313:IDP_20200612 dumpfile=DATA.DMP remap_schema=idp_20170313:IDP_20200612 transform=OID:N

impdp SYSWARE_ORM_340_UPGRADE/SYSWARE_ORM_340_UPGRADE@sysware directory=DPDIROEM20230414 remap_tablespace=SYSWARE_ORM_342_DEMO:SYSWARE_ORM_340_UPGRADE dumpfile=kmdata_exp.dmp remap_schema=SYSWARE_ORM_342_DEMO:SYSWARE_ORM_340_UPGRADE transform=OID:N

impdp SYSWARE_ORM_343_VERSION/SYSWARE_ORM_343_VERSION@sysware directory=DPDIROEM230704 remap_tablespace=SYSWARE_343_DEMO:SYSWARE_ORM_343_VERSION dumpfile=data.dmp remap_schema=SYSWARE_343_DEMO:SYSWARE_ORM_343_VERSION transform=OID:N

SYSWARE_343_DEMO

--sqlplus IDP_20200612/IDP_20200612@localhost:1521/sysware
