Oracle 数据迁移升级（XTTS + DBUA）

迁移升级背景介绍

测试环境：VMware® Workstation 15 Pro 虚拟机
操作系统：CentOS Linux release 7.6.1810 (Core)
系统内核：3.10.0-957.el7.x86_64
硬件架构：x86_64
软件版本：Oracle 11.2.0.4，Oracle 19.3.0.0

节点名称	处理器	内存	硬盘	IP地址（公网）	IP地址（私网）
orclrac1	2C 2core	3GB	30GB	192.168.32.139	192.168.49.192
orclrac2	2C 2core	3GB	30GB	192.168.32.140	192.168.49.193
orcl19c	1C 1core	2GB	30GB	192.168.32.143

源端：orclrac1，orclrac2
目标端：orcl19c

迁移阶段准备

在USERS表空间下创建了测试用户和测试数据

检验自包含

select distinct tablespace_name from dba_segments where owner='EODA' order by 1;
execute dbms_tts.transport_set_check('USERS');
select * from TRANSPORT_SET_VIOLATIONS;
-- 上述查询若没有结果行返回，说明自包含校验通过

创建XTTS工作目录

-- 源端创建相关目录
mkdir -p /home/oracle/exp/newxx
mkdir -p /home/oracle/exp/newxx/src_backup
mkdir -p /home/oracle/exp/newxx/tmp
mkdir -p /home/oracle/exp/newxx/dump
mkdir -p /home/oracle/exp/newxx/backup_incre
chown -R oracle:dba /home/oracle/exp/newxx

解压 unzip rman_xttconvert_v3.zip
[oracle@orclrac1 ~]$ tree exp/newxx/
exp/newxx/
|-- backup_incre
|-- dump
|-- src_backup
|-- tmp
|-- xttcnvrtbkupdest.sql
|-- xttdbopen.sql
|-- xttdriver.pl
|-- xttprep.tmpl
|-- xtt.properties
`-- xttstartupnomount.sql

-- 目标端创建相关目录
mkdir -p /home/oracle/exp/newxx
mkdir -p /home/oracle/exp/newxx/src_backup
mkdir -p /home/oracle/exp/newxx/tmp
mkdir -p /home/oracle/exp/newxx/dump
mkdir -p /home/oracle/exp/newxx/backup_incre
chown -R oracle:dba /home/oracle/exp/newxx

源端开启bct

SYS@orclrac1> alter database enable block change tracking using file '+DATA/bct/bct2';

配置 xtt.properties

-- 源端配置
[oracle@orclrac1 ~]$ cd exp/newxx/
[oracle@orclrac1 newxx]$ vim xtt.properties
-- 增加如下配置信息：
tablespaces=USERS
platformid=13
dfcopydir=/exp/newxx/src_backup
backupformat=/exp/newxx/backup_incre
backupondest=/exp/newxx/backup_incre
stageondest=/exp/newxx/src_backup
storageondest=+DATA/orclrac
parallel=16
rollparallel=16
getfileparallel=6
-- platformid参数取自，select platform_id from v$database查询的结果

-- 目标端配置
[oracle@orcl19c ~]$ cd exp/newxx/
[oracle@orcl19c newxx]$ vim xtt.properties
-- 增加如下配置信息：
tablespaces=USERS
platformid=13
dfcopydir=/exp/newxx/src_backup
backupformat=/exp/newxx/backup_incre
backupondest=/exp/newxx/backup_incre
stageondest=/exp/newxx/backup_incre
storageondest=/u01/app/oracle/oradata/ORCL/datafile
parallel=16
rollparallel=16
getfileparallel=6
-- asm_home=/opt/app/11.2.0/grid
-- asm_sid=+ASM1
-- 目标端是单实例，没有启用ASM管理

目标端提前建立用户角色

-- 目标端创建EODA用户，完成元数据导入后才可修改默认表空间。
以下是在源端执行获取创建用户和对应角色、权限的语句后，在目标端对应创建（如果你很清楚要迁移业务用户的用户密码和权限等信息，也可以选择直接创建）：
-- 源端执行
[oracle@orclrac1 newxx]$ mkdir scripts
-- create user
[oracle@orclrac1 ~]$ sqlplus -S / as sysdba
set pages 0
set feedback off
spool /home/oracle/exp/newxx/scripts/create_user.sql
select 'create user '||name||' identified by values '''||password||''';' from user$ where name = 'EODA' and type#=1;
create user EODA identified by values 'D289D40C00A789DC';
spool off
exit

-- create role
[oracle@orclrac1 ~]$ sqlplus -S / as sysdba
set pages 0
set feedback off
spool /home/oracle/exp/newxx/scripts/create_role.sql
select 'grant '||GRANTED_ROLE||' to '||grantee||';' from dba_role_privs where grantee = 'EODA';
grant DBA to EODA;
spool off
exit
