XTTS迁移oracle11g-19c（非容器数据库）
一.背景
尝试把用xtts把oracle 11g单实例数据库迁移到19c非CDB单实例数据库中。
二.环境介绍
源端：11g：
操作系统：
[root@11g ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)
数据库版本：11.2.0.4
IP地址：192.168.59.180
目标端：19c：
操作系统：
[root@19c ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
数据库版本：19.3.0.0
IP地址：192.168.59.181
所需软件：
rman_xttconvert_v3.zip
下载：
链接：https://pan.baidu.com/s/1ZRqkPzLVKtnnI_xQtRnADg
提取码：fhx7
三.迁移
3.1.准备阶段
3.1.1.生产库打开块跟踪特性
alter database enable block change tracking using file '/u01/xtts/block_change_tracking.log';
3.1.2.对表空间做自包含检查
检查出INDEX存在自包含问题，需要重建或者最后重建。
本次我们迁移的用户为TEST1和TEST2，涉及的表空间为TEST1和TEST2。
3.1.2.对表空间做自包含检查 检查出INDEX存在自包含问题，需要重建或者最后重建。 本次我们迁移的用户为TEST1和TEST2，涉及的表空间为TEST1和TEST2。
3.1.3.找出临时表的创建语句
因为XTTS在最后导入元数据的时候不支持临时表，所以需要提前查出临时表信息，在导入元数据之后手动执行。
SQL> Select dbms_metadata.get_ddl('TABLE',TABLE_NAME,OWNER) FROM dba_tables where TEMPORARY='Y' and owner='TEST1'; no rows selected SQL> Select dbms_metadata.get_ddl('TABLE',TABLE_NAME,OWNER) FROM dba_tables where TEMPORARY='Y' and owner='TEST2'; no rows selected
3.2.XTTS迁移初始化阶段
3.2.1.上传rman_xttconvert_v3.zip 到oracle 11g上
解压之后会有如下文件：
[oracle@11g rman-xttconvert]$ ll total 172 -rw-r--r-- 1 oracle oinstall 1390 May 24 2017 xttcnvrtbkupdest.sql -rw-r--r-- 1 oracle oinstall 71 May 24 2017 xttdbopen.sql -rw-r--r-- 1 oracle oinstall 142020 Sep 20 2018 xttdriver.pl -rw-r--r-- 1 oracle oinstall 11710 May 24 2017 xttprep.tmpl -rw-r--r-- 1 oracle oinstall 8028 Dec 17 10:53 xtt.properties -rw-r--r-- 1 oracle oinstall 52 May 24 2017 xttstartupnomount.sql [oracle@11g rman-xttconvert]$
3.2.2.源端更改配置文件xtt.properties
更改以下参数：
tablespaces=TEST1,TEST2 platformid=13 dfcopydir=/u01/xtts/bak backupformat=/u01/xtts/bakincr stageondest=/u01/xtts/oradata2 storageondest=/u01/xtts/oradata3 parallel=16 rollparallel=8 getfileparallel=8 desttmpdir=/u01/xtts/temp dumpdir=/u01/xtts/dump 附录解释： tablespaces= ----需要迁移的表空间 platformid= ----源 OS 平台 ID V$DATABASE.PLATFORM_ID dfcopydir= ----源数据库备份文件存放目录 backupformat= ---源数据库增备文件存放目录 stageondest= ----目标据库备份文件存放目录 storageondest= ----目标据库正式文件存放目录 parallel= ----备份，转化的并行度 rollparallel= ----增备的并行度
3.2.3.创建上述目录并将rman-xttconvert目录传输至目标端
创建相应目录： 源端： mkdir -p /u01/xtts/bak mkdir -p /u01/xtts/bakincr mkdir -p /u01/xtts/temp mkdir -p /u01/xtts/dump [oracle@11g software]$ scp -r rman-xttconvert/ 192.168.59.181:/home/oracle/ 目标端： mkdir -p /u01/xtts/oradata2 mkdir -p /u01/xtts/oradata3 mkdir -p /u01/xtts/temp mkdir -p /u01/xtts/dump mkdir -p /u01/xtts/incr
3.3.初始备份
3.3.1.源端进行初始备份
export TMPDIR=/u01/xtts/temp $ORACLE_HOME/perl/bin/perl xttdriver.pl -p [oracle@11g rman-xttconvert]$ $ORACLE_HOME/perl/bin/perl xttdriver.pl -p ============================================================ trace file is /u01/xtts/temp/prepare_Feb7_Mon_14_31_25_313//Feb7_Mon_14_31_25_313_.log ============================================================= -------------------------------------------------------------------- Parsing properties -------------------------------------------------------------------- -------------------------------------------------------------------- Done parsing properties -------------------------------------------------------------------- -------------------------------------------------------------------- Checking properties -------------------------------------------------------------------- -------------------------------------------------------------------- Done checking properties -------------------------------------------------------------------- -------------------------------------------------------------------- Starting prepare phase -------------------------------------------------------------------- Prepare source for Tablespaces: 'TEST1' /u01/xtts/oradata2 xttpreparesrc.sql for 'TEST1' started at Mon Feb 7 14:31:25 2022 xttpreparesrc.sql for ended at Mon Feb 7 14:31:25 2022 Prepare source for Tablespaces: 'TEST2' /u01/xtts/oradata2 xttpreparesrc.sql for 'TEST2' started at Mon Feb 7 14:31:30 2022 xttpreparesrc.sql for ended at Mon Feb 7 14:31:30 2022 -------------------------------------------------------------------- Done with prepare phase -------------------------------------------------------------------- -------------------------------------------------------------------- Find list of datafiles in system -------------------------------------------------------------------- -------------------------------------------------------------------- Done finding list of datafiles in system -------------------------------------------------------------------- [oracle@11g rman-xttconvert]$
3.3.2.传输初始备份
将/u01/xtts/bak和/u01/xtts/temp目录下面的文件拷贝到目标环境对应的目录下 scp -r /u01/xtts/bak/* oracle@192.168.59.181:/u01/xtts/oradata2 scp -r /u01/xtts/temp/* oracle@192.168.59.181:/u01/xtts/temp

3.7.3.修改用户默认表空间信息
SQL> alter user test1 default tablespace test1; User altered. SQL> alter user test2 default tablespace test2; User altered.
3.8.检查无效对象并验证数据
select 'ALTER' ||OBJECT_TYPE||''||OWNER||'.'|| OBJECT_NAME||'COMPILE;' from all_objects where status='INVALID' AND object_type in ('PACKAGE','FUNCTION','PROCEDURE','TABLE','VIEW','SEQUENCE','TRIGGER'); --验证数据 --源端： SQL> select object_type,count(*) from dba_objects where owner in ('TEST1','TEST2') group by object_type order by 2; OBJECT_TYPE COUNT(*) ------------------- ---------- TABLE 2 INDEX 2 TABLE PARTITION 18 --目标端： OBJECT_TYPE COUNT(*) ----------------------- ---------- TABLE 2 TABLE PARTITION 18
可以看到，之前源端创建在users表空间的索引没有迁移过来。需要我们重新创建。
3.9.清理环境
/u01/xtts目录清理
四.总结
4.1.步骤总结
-
首先确定需要迁移的表空间，检查是否自包含。
-
找出临时表的创建语句，元数据导入之后手动进行创建。
-
初始化参数修改阶段。 目标端初始化备份文件和增量备份文件放同一个目录。
-
增量备份前滚阶段，可以多次进行。
-
最后一次增量备份阶段。
-
导入元数据。
-
校验数据
4.2.报错总结
-
增量前滚阶段目标端应用报错 : scn号设置错误 增量备份文件存放目录错误
-
导入表空间元数据报错：没有创建用户
