XTTS跨平台表空间增量迁移

一、准备工作

1.1、平台检查

column platform_name format a30

SQL> select * from V$TRANSPORTABLE_PLATFORM order by 1;

PLATFORM_ID PLATFORM_NAME                            ENDIAN_FORMAT

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

          1 Solaris[tm] OE (32-bit)                  Big

          2 Solaris[tm] OE (64-bit)                  Big

          3 HP-UX (64-bit)                           Big

          4 HP-UX IA (64-bit)                        Big

          5 HP Tru64 UNIX                            Little

          6 AIX-Based Systems (64-bit)               Big

          7 Microsoft Windows IA (32-bit)            Little

          8 Microsoft Windows IA (64-bit)            Little

          9 IBM zSeries Based Linux                  Big

         10 Linux IA (32-bit)                        Little

         11 Linux IA (64-bit)                        Little

PLATFORM_ID PLATFORM_NAME                            ENDIAN_FORMAT

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

         12 Microsoft Windows x86 64-bit             Little

         13 Linux x86 64-bit                         Little

         15 HP Open VMS                              Little

         16 Apple Mac OS                             Big

         17 Solaris Operating System (x86)           Little

         18 IBM Power Based Linux                    Big

         19 HP IA Open VMS                           Little

         20 Solaris Operating System (x86-64)        Little

         21 Apple Mac OS (x86-64)                    Little

20 rows selected.

 

角色	代号	系统版本	平台名称	字序
源	2	Solaris11	Solaris[tm] OE (64-bit)	Big
目标	13	SUSE 11.2	Linux x86 64-bit	Little

 

此次为跨字节序的迁移动作。

 

1.2、待传输表空间检查

确定要传输的表空间是否字包含，如果传输多个表空间，中间加逗号。

EXECUTE DBMS_TTS.TRANSPORT_SET_CHECK('TEST1,TEST2,TEST3',true) ;

 

SELECT * FROM TRANSPORT_SET_VIOLATIONS;

 

 

 

1.3、Xtts全量+增量流程

源端上传rman-xttconvert_2.0

 

软件上传目录：

源端          sourcedir   /soft/sourcedir

目标端       targetdir    /soft/targetdir

TMP目录   export TMPDIR=/soft/tempdir/

 

 

1.3.1、xtt.properties

tablespaces=TEST1,TEST2,TEST3,ROCK

platformid=2

dfcopydir=/soft/dfcopydir                         --源端创建

backupformat=/soft/backupformat           --源端创建

stageondest=/soft/stageondest               --目标端创建

storageondest=+DATA/ROCK/datafile

backupondest=+DATA/ROCK/datafile

1.3.1.1、 参数说明：

tablespaces=xttbs,xtidx 要迁移的表空间

platformid=2 source端platform编号，查看V$TRANSPORTABLE_PLATFORM视图

srcdir=/u01/app/oracle/oradata/startrek 与dstdir联合使用，有点像dg中的convert，当数据文件在源端以及target端不一致的时候可以使用

dstdir=/u01/app/oracle/oradata/startrek

dfcopydir=/u01/sourcedir/dfcopy 源端目录，使用rmanbackup的时候，将datafile copy放置在源端的目录

backupformat=/u01/sourcedir/incbk 源端目录，源端增量备份生成的目录

stageondest=/u01/targetdir/datafiledir 目标端目录，源端的datafilecopy 传输到目标段临时存放的目录。（未转换前）

storageondest=/u01/target/rmanbk 目标端目录，datafile copy以及incremental backup 使用-c转换后的目录。正经需要使用的目录，转换后的数据文件会在这个目录生成。如果目标端为asm可以设定为+DATA磁盘组名称。

backupondest=/u01/target/rmaninc 目标段目录，当使用-r roll forward datafiles 阶段，inc backup存放的目录。使用rman incremental recover的时候不需要这个参数。如果目标端为asm可以设定为+DATA磁盘组名称。

 

 

1.3.2、源端首次全量导出

[oracle@node1 sourcedir]$

 

 

1.3.2.1、脚本说明：

这个脚本执行三个主要步骤

1、Creates datafile copies of the tablespaces that will be transported in the location specified by the xtt.properties parameterdfcopydir.

创建给定表空间相关的数据文件copy到dfcopydir下面。

 

2、Verifies the tablespaces are online, in READ WRITE mode, and do not contain offline datafiles.

验证给定的表空间为online、readwrite、不包含offline的数据文件

 

3、Creates the following files used later in this procedure:

xttplan.txt

rmanconvert.cmd

创建两个相关的文件xttplan.txt,rmanconvert.cmd，存放于TMPDIR下

1.3.3、目标端首次recover

 

·   将源端的xtts目录复制到目标端

·   将源端生成的rmanconvert.cmd   xttplan.txt   复制到目标端TMP目录

·   ROCK_9.tf  TEST1_6.tf  TEST2_7.tf  TEST3_8.tf  复制到目标端/soft/stageondest 目录

 

 

目标端执行下面的语句：

$ORACLE_HOME/perl/bin/perl xttdriver.pl -c

[oracle@node2 targetdir]$ $ORACLE_HOME/perl/bin/perl xttdriver.pl -c

1.3.4.1、增量生成文件说明

增量脚本执行后会生成如下六个文件：

0nro1rbk_1_1  0oro1rbo_1_1  0pro1rbs_1_1  0qro1rbv_1_1

tsbkupmap.txt

incrbackups.txt

 

[oracle@node1 tempdir]$ cat rmanincr.cmd

set nocfau;

host 'echo ts::TEST1';

backup incremental from scn 3184044

  tag tts_incr_update tablespace 'TEST1'  format

 '/soft/backupformat/%U';

set nocfau;

backup incremental from scn 3157443

  tag tts_incr_update tablespace 'TEST3'  format

 '/soft/backupformat/%U';

set nocfau;

host 'echo ts::ROCK';

backup incremental from scn 3157515

  tag tts_incr_update tablespace 'ROCK'  format

 '/soft/backupformat/%U';

TEST3::8:::1=0pro1rbs_1_1

ROCK::9:::1=0qro1rbv_1_1

TEST2::7:::1=0oro1rbo_1_1

 

1.3.5、增量导出传输至目标端

 

将/soft/dfcopydir目录下的增量导出文件copy到target端的stageondest目录下。

将tsbkupmap.txt以及新生成的xttplan.txt.new文件copy到target端的TMPDIR目录

重命名xttplan.txt.new为xttplan.txt

[oracle@node2 tempdir]$ mv xttplan.txt.new xttplan.txt

 

1.3.6、目标端增量导入

 

$ORACLE_HOME/perl/bin/perl xttdriver.pl -r

[oracle@node2 targetdir]$ $ORACLE_HOME/perl/bin/perl xttdriver.pl -r

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

1.3.7、源端刷新FROM_SCN

 

源端执行下面的脚本以确定下一次执行incremental backup的 from_scn

$ORACLE_HOME/perl/bin/perl xttdriver.pl -s

 

1.3.8、goto 1.3.4

 

在最后一次增量导出前repeat重复1.3.4至1.3.7的内容。

每次增量前执行：$ORACLE_HOME/perl/bin/perl xttdriver.pl –s

 

 

二、停机时间

2.1、将生产系统待传输表空间设置为readonly

通过脚本生成批量语句，并删除不需要传输的表空间语句：

select ‘alter tablespace ‘||tablespace_name||’ read only;’||from dba_tablespaces;

SQL> alter tablespace xttbs read only ;

Tablespace altered.

SQL> alter tablespace xtidx read only ;

Tablespace altered.

SQL>

 

2.2、执行最后一次增量备份

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

 

2.3、增量传输

将/soft/dfcopydir目录下的增量导出文件copy到target端的stageondest目录下。

将tsbkupmap.txt以及新生成的xttplan.txt.new文件copy到target端的TMPDIR目录

重命名xttplan.txt.new为xttplan.txt

 

 

2.4、执行最后一次增量恢复

[oracle@dest]$ $ORACLE_HOME/perl/bin/perl xttdriver.pl –r

 

 

2.5、目标端生成impdp脚本

? 如下命令可以生成一个impdp的脚本，适当修改即可。（此处不使用dblink,仅使用以下脚本的transport_datafiles项）

 

[oracle@dest]$ $ORACLE_HOME/perl/bin/perl xttdriver.pl -e

 [oracle@node2 tempdir]$ cat xttplugin.txt

impdp directory= logfile= \

network_link= transport_full_check=no \

transport_tablespaces=TEST1,TEST2,TEST3 \

transport_datafiles='+DATA/rock/datafile/test1_6.xtf','+DATA/rock/datafile/test2_7.xtf','+DATA/rock/datafile/test3_8.xtf'

[oracle@node2 tempdir]$

 

 

 

2.6、源端表空间元数据导出

 

? 创建directory

CREATE DIRECTORY test as ‘/soft/dump’

 

? Expdp导出元数据

[oracle@node1 dump]$ expdp rock/rock dumpfile=test.dump directory=test transport_tablespaces=test1,test2,test3 logfile=dump.log

2.8、目标端用户创建

?  修改上面生成的脚本并在目标端运行

?  修改用户的默认表空间

select 'alter user '||username||' '||'default tablespace '||default_tablespace||';' from dba_users;

2.9、目标端表空间元数据导入

? 传送表空间元数据导出文件test.dmp到target端的directory目录并执行导入。

 

 

[oracle@node2 tempdir]$ impdp system/manager directory=test logfile=imp.log dumpfile=test.dump transport_datafiles='+DATA/test1_6.xtf','+DATA/test2_7.xtf','+DATA/test3_8.xtf'

导入结束后相关的表都级联生成

 

 

 

三、TIPS:方案优势及参考文献

优势：停机时间极少

数据库的down机时间取决于最后一次执行incremental的速度。

随着执行incremental的次数的增加down机时间越来越少。

 

参考文档：

11G - Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup (文档 ID 1389592.1)

四、排错

1.报Cant find xttplan.txt, TMPDIR undefined at xttdriver.pl line 1185.

?  设定环境变量TMPDIR=/home/oracle/xtts/script 

2.Unable to fetch platform name

?  执行xttdriver.pl之前指定ORACLE_SID

3.Some failure occurred. Check /home/oracle/xtts/script/FAILED for more details

      If you have fixed the issue, please delete /home/oracle/xtts/script/FAILED and run it

      again OR run xttdriver.pl with -L option

?  执行xttdriver.pl报错后,下次执行要删除FAILED文件.

4.Can't locate strict.pm in @INC

?  使用$ORACLE_HOME/perl/bin/perl而不是使用perl
