手工 XTTS CPT 迁移-跨平台迁移数据库-阿里云开发者社区

-- xtts 跨平台迁移数据库

-- 步骤：

1、初始化参数设置；

2、将源端数据文件传输到目标系统；

3、转换数据文件为目标系统的字节序；

4、在源端创建增量备份，并传输到目标端；

5、在目标端恢复增量备份；

6、重复多次操作4和5步骤；

7、将源端数据库表空间设置为 READ ONLY 模式；

8、最后一次执行4和5步骤；

9、在源端导出元数据，并在目标端导入；

10、将目标端的数据库表空间设置为 READ WRITE；

11、数据验证。

-- 下次增量要记录当前恢复的scn位置，产生最新 xttplan.txt 文件，要不然下次增量还会在全量进行备份

perl xttdriver.pl -s

-- 后续增量循环以下三步骤

sh do_incr.sh

sh restore_incr.sh

perl xttdriver.pl -s

-- 最后一次增量，表空间设置为只读模式

SQL> alter tablespace SPROD_TBS read only;

Tablespace altered.

SQL> alter tablespace IDX_TBS read only;

Tablespace altered.

-- 最后一次恢复

sh do_incr.sh

sh restore_incr.sh

----------------------------------------------------------------------------------------

-- 传输表空间

传输表空间的步骤可以和最后一次增量备份同时执行，可开并行

方法1：

-- 目标端执行，得到impdp脚本

$ORACLE_HOME/perl/bin/perl xttdriver.pl –e

impdp system/oracle directory=ddmp logfile=impdp_xtts_20180527.lognetwork_link=TEST \

transport_full_check=no \

transport_tablespaces=TEST,TEST_IND \

transport_datafiles='/data3/oradata/targetdb/TEST_5.dbf','/data3/oradata/targetdb/TEST_IND_6.dbf'

方法2：

-- 手工导出导入表空间

源端

expdp system/oracle directory=sdmp dumpfile=xtts.dmplogfile=expdp_xtts_20180527.log transport_tablespaces=TEST,TEST_INDtransport_full_check=no;

-- 复制导出的文件到目标端

目标端

impdp system/oracle directory=ddmp dumpfile=xtts.dmplogfile=impdp_xtts_20180527.logtransport_datafiles='/app/oradata/targetdb/TEST_5.dbf,/app/oradata/targetdb/TEST_IND_6.dbf'

-- 验证，传输完成后应该能够看到所有表空间，并且能够查询其中的数据

set pagesize 2000

set linesize 200

col file_name for a40

col OBJECT_NAME for a30

select TABLESPACE_NAME from dba_tablespaces;

----------------------------------------------------------------------------------------

-- 导入元数据

-- 源端检查表空间的自包含性

SQL> EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('TEST02', TRUE);

SQL> SELECT * FROM TRANSPORT_SET_VIOLATIONS;

no rows selected

$ expdp system/oracle directory=source_dbdata dumpfile=test02.dmp transport_tablespaces=test02 transport_full_check=y

$ impdp test02/test02 DUMPFILE=test02.dmp DIRECTORY=source_dbdata TRANSPORT_DATAFILES=/home/oracle/xtts/target_data/TEST02_7.dbf

-- xtts 跨平台迁移数据库 2

1、源和目标库创建数据库对应的目录,目标库创建公共DBLink使用 system 用户

# source db

create or replace directory ora10g_dbf_dir as '+DATA/ora10g/datafile';

create or replace directory xttsfiles as '/home/oracle/xttsfiles';

grant read,write on directory ... to public;

# target db

create or replace directory ora12c_dbf_dir as '+DATA/ora12c/datafile';

create or replace directory xttsfiles as '/home/oracle/xttsfiles';

grant read,write on directory ... to public;

create database link ORA10G_LINK connect to system identified by system using 'ORA10G';

2、解压 XTTS

unzip -d /home/oracle/xtts rman_xttconvert_1.4.zip

3、编辑 xtts.properties 配置文件

vi xtts.properties

tablespace=AP_DATA,AP_IDX

# source db param

platform=2

srcdir=ora10g_dbf_dir

srclink=ora10g_link

dfcopydir=/home/oracle/xttsfiles

backupformat=/home/oracle/xttsfiles

# target db param

dstdir=ora12c_dbf_dir

stageondest=/home/oracle/xttsfiles

storageondest=+DATA

backupondest=+FRA

asm_home=/u01/app/12.1.0/grid

asm_sid=+ASM

parallel=4

rollparallel=2

4、执行脚本

-- 初始提取

Generate initial datafile image copies:

$ ./xttdriver.pl -S

Copy scripts & files to destination platform:

$ scp ... ...

Pull initial datafile image copies to destination:

$ ./xttdriver.pl -G

Conversion handled implicitly!

-- 增量同步

Generate INCREMENTAL LEVEL 1 backup sets:

$ ./xttdriver.pl -i

Copy scripts & files to destination platform:

$ scp ... ...

Capture SCN of last synchronization:

$ ./xttdriver.pl -s

Use INCREMENTAL LEVEL 1 backup sets to recover datafile image copies to current SCN:

$ ./xttdriver.pl -r

-- 当源库与目标库期望接近时，DBA决定完成迁移，则将所有需要XTTS迁移的对象设置为只读模式，

alter tablespace ... read only;

-- 直到最后一个1级增量备份被捕获兵传输到目标库，然后应用于0级备份，在最后一次恢复。

-- 最终同步

Generate INCREMENTAL LEVEL 1 backup sets:

$ ./xttdriver.pl -i

Copy scripts & files to destination platform:

$ scp ... ...

Capture SCN of last synchronization:

$ ./xttdriver.pl -s

Use INCREMENTAL LEVEL 1 backup sets to recover datafile image copies to final SCN:

$ ./xttdriver.pl -r

Import metadata into destination database:

$ ./xttdriver.pl -e

-- CPT(Cross-Platform Transport) 跨平台迁移数据库

Backup READ ONLY tablespace as backup sets:

rman target /

Copy datafile backup sets to target database 12.1.0.2
