XTTS遷移oracle11g-19c（非容器數據庫）
一.背景
嘗試把用xtts把oracle 11g單實例數據庫遷移到19c非CDB單實例數據庫中。
二.環境介紹
源端：11g：
操作系統：
[root@11g ~]# cat /etc/redhat-release
Red Hat Enterprise Linux Server release 6.4 (Santiago)
數據庫版本：11.2.0.4
IP地址：192.168.59.180
目標端：19c：
操作系統：
[root@19c ~]# cat /etc/redhat-release
CentOS Linux release 7.9.2009 (Core)
數據庫版本：19.3.0.0
IP地址：192.168.59.181
所需軟件：
rman_xttconvert_v3.zip
下載：
鏈接：https://pan.baidu.com/s/1ZRqkPzLVKtnnI_xQtRnADg
提取碼：fhx7
三.遷移
3.1.准備階段
3.1.1.生產庫打開塊跟蹤特性
alter database enable block change tracking using file '/u01/xtts/block_change_tracking.log';
3.1.2.對表空間做自包含檢查
檢查出INDEX存在自包含問題，需要重建或者最后重建。
本次我們遷移的用戶為TEST1和TEST2，涉及的表空間為TEST1和TEST2。
3.1.2.對表空間做自包含檢查 檢查出INDEX存在自包含問題，需要重建或者最后重建。 本次我們遷移的用戶為TEST1和TEST2，涉及的表空間為TEST1和TEST2。
3.1.3.找出臨時表的創建語句
因為XTTS在最后導入元數據的時候不支持臨時表，所以需要提前查出臨時表信息，在導入元數據之后手動執行。
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遷移初始化階段
3.2.1.上傳rman_xttconvert_v3.zip 到oracle 11g上
解壓之后會有如下文件：
[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
更改以下參數：
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 附錄解釋： tablespaces= ----需要遷移的表空間 platformid= ----源 OS 平台 ID V$DATABASE.PLATFORM_ID dfcopydir= ----源數據庫備份文件存放目錄 backupformat= ---源數據庫增備文件存放目錄 stageondest= ----目標據庫備份文件存放目錄 storageondest= ----目標據庫正式文件存放目錄 parallel= ----備份，轉化的並行度 rollparallel= ----增備的並行度
3.2.3.創建上述目錄並將rman-xttconvert目錄傳輸至目標端
創建相應目錄： 源端： mkdir -p /u01/xtts/bak mkdir -p /u01/xtts/bakincr mkdir -p /u01/xtts/temp mkdir -p /u01/xtts/dump [oracle@11g software]$ scp -r rman-xttconvert/ 192.168.59.181:/home/oracle/ 目標端： 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.初始備份
3.3.1.源端進行初始備份

3.3.2.傳輸初始備份
將/u01/xtts/bak和/u01/xtts/temp目錄下面的文件拷貝到目標環境對應的目錄下 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.修改用戶默認表空間信息
SQL> alter user test1 default tablespace test1; User altered. SQL> alter user test2 default tablespace test2; User altered.
3.8.檢查無效對象並驗證數據
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'); --驗證數據 --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 --目標端： OBJECT_TYPE COUNT(*) ----------------------- ---------- TABLE 2 TABLE PARTITION 18
可以看到，之前源端創建在users表空間的索引沒有遷移過來。需要我們重新創建。
3.9.清理環境
/u01/xtts目錄清理
四.總結
4.1.步驟總結
-
首先確定需要遷移的表空間，檢查是否自包含。
-
找出臨時表的創建語句，元數據導入之后手動進行創建。
-
初始化參數修改階段。 目標端初始化備份文件和增量備份文件放同一個目錄。
-
增量備份前滾階段，可以多次進行。
-
最后一次增量備份階段。
-
導入元數據。
-
校驗數據
4.2.報錯總結
-
增量前滾階段目標端應用報錯 : scn號設置錯誤 增量備份文件存放目錄錯誤
-
導入表空間元數據報錯：沒有創建用戶
