7 源库/目标库
在源库和目标库创建升级用户
CREATE USER migups IDENTIFIED BY XXXXXX
DEFAULT TABLESPACE users
TEMPORARY TABLESPACE temp
QUOTA UNLIMITED ON users;
GRANT dba TO migups;
GRANT select ON sys.user$ TO migups;
GRANT SELECT ANY DICTIONARY TO migups;
GRANT RESTRICTED SESSION TO migups;
GRANT EXECUTE ON SYS.DBMS_LOCK TO migups;
8 源库
在源生产库创建要迁移的用户清单配置表(dbmgr.s_user_cfg)
create table dbmgr.s_user_list as select username,1 as GGFLAG
FROM dba_users where username not in (
'SYS','SYSTEM','MIGUPS','ANONYMOUS','OUTLN','EXFSYS','DBSNMP','WMSYS','APPQOSSYS','OLAPSYS','DIP','ORACLE_OCM','XS$NULL','XDB','SYSMAN'
)
9 目标库
在目标库创建迁移用的临时dblink
1:在目标库创建迁移用的临时dblink ---直接使用连接串
create public database link dblink_old connect to migups identified by XXXXX
using '(description=(address=(protocol=tcp)(host=XXXXXXX)(port=1521))(connect_data=(sid=test)))';
2:验证dblink是否通
select * from dual@dblink_old; --有结果返回表示通的否则不通需处理"
10 目标库 目标库创建角色
在pc server目标库生成角色创建脚本：
select 'create role '||role||';' from dba_roles@dblink_old where role not in (select role from dba_roles);
在pc server目标库执行上述脚本进行角色创建。
11 目标库 搭建目标新库同城容灾
正式迁移
序列 环境 操作步骤 具体操作内容 备注
1 源库 源库停应用、监控
2 源库 源库设置表空间只读
alter tablespace users read only;
alter tablespace test read only;
.
.
.
.
复核检查：待传输的表空间状态都为read only。
select tablespace_name, status from dba_tablespaces a
where (a.tablespace_name not in ('TEMP', 'SYSAUX', 'SYSTEM') and
a.contents not in ('TEMPORARY', 'UNDO'));"
3 源库 源库按用户做导出
