oracle表空间文件系统迁移到ASM

Posted 2021-02-03

1.配置测试环境
创建数据表空间
create tablespace test logging datafile ‘/home/oracle/test.dbf‘ size 10m autoextend on next 10m maxsize 2048m extent management local;
创建用户并指定表空间
create user test identified by 123456 default tablespace test;
给用户授予权限
grant connect,resource,dba to test;
创建表
sqlplus test/[email protected]
CREATE TABLE test2(userId number(8), username varchar2(40), tep number (20)) PARTITION BY RANGE (userId)(PARTITION p1 VALUES LESS THAN (10000), PARTITION p2 VALUES LESS THAN (20000), PARTITION p3 VALUES LESS THAN (30000) );
查询当前用户下的表：
select tname from tab;

2.文件系统表空间迁移到ASM中去
rman target /
report schema; 查看表空间
sql ‘alter tablespace test offline‘;离线表空间
backup as copy datafile 5 format ‘+DATA‘;Copy类型备份表空间
switch datafile 5 to copy;切换表空间文件到copy副本
sql ‘alter tablespace test online‘;上线表空间
report schema;

sqlplus / as sysdba
select ts#,name from v$tablespace where name=‘TEST‘ union all select file#,name from v$datafile where ts#=6;
select * from v$dbfile;

sqlplus test/[email protected]
select tname from tab;
