1、初始化阶段
1.1、源端数据库
源端数据库testdb,数据库版本11.2.0.3.0,运行在AIX 64-bit

db1:/oracle/db/bin$echo $ORACLE_HOME

SYS@testdb1 > select name, platform_id, platform_name fromv$database;
NAME PLATFORM_IDPLATFORM_NAME
--------------------------- ----------- ------------------------------
TESTDB 6 AIX-BasedSystems (64-bit)
需要进行迁移的表空间为XTTSTEST:
select t.name "Tablespace", f.file# "File#",f.name "Filename", f.status "Status"
from v$datafile f, v$tablespace t
where f.ts#=t.ts# and t.name like 'XTTS%'
order by 1, 2;
Tablespace File# Filename Status
---------- ------------------------------------------------------------ -------
XTTSTEST 41 +ORADATA/testdb/datafile/xttstest.362.959887907 ONLINE
SYS@testdb1 >
在源端为DBMS_FILE_TRANSFER创建目录SOURCEDIR,其路径为迁移表空间数据文件路径
SYS@testdb1 > create directory sourcedir as '+ORADATA/testdb/datafile';
Directory created.
源端数据库必须为归档模式
SYS@testdb1 > archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 11771
Next log sequence to archive 11775
Current log sequence 11775
如下为oracle用户设置TMPDR环境变量
export TMPDIR=/home/oracle/tts
上传rman-xttconvert_2.0.zip至/home/oracle/tts目录并解压
db1:/home/oracle/tts$unzip rman-xttconvert_2.0.zip
Archive: rman-xttconvert_2.0.zip
inflating: xttcnvrtbkupdest.sql
inflating: xttdbopen.sql
inflating: xttdriver.pl
inflating: xttprep.tmpl
inflating: xtt.properties
inflating: xttstartupnomount.sql
对xtt.properties文件进行如下配置
db1:/home/oracle/tts$grep ^[a-z] xtt.properties
tablespaces=XTTSTEST
platformid=6
srcdir=SOURCEDIR
dstdir=DESTDIR
srclink=TTSLINK
dfcopydir=/home/oracle/stage_source
backupformat=/home/oracle/stage_source
stageondest=/home/oracle/stage_dest
backupondest=+FRA_SB
asm_home=/testdb/orgrid/oracle/product/112
asm_sid=+ASM1
xtt.properties文件里的大部分参数都有说明,可以参照说明进行配置。需要注意的是platformid必须设置成源端数据库platform id,platform id可以从v$database查询到。
xtt.properties在源端配置完成后,拷贝到目标端:
db1:/home/oracle$scp -r tts x.x.x.81:/home/oracle
oracle@x.x.x.81's password:
rman-xttconvert_2.0.zip 100% 26KB 26.3KB/s 00:00
xtt.properties 100% 7820 7.6KB/s 00:00
xttcnvrtbkupdest.sql 100% 1390 1.4KB/s 00:00
xttdbopen.sql 100% 71 0.1KB/s 00:00

xttprep.tmpl 100% 11KB 11.3KB/s 00:00
xttstartupnomount.sql 100% 52 0.1KB/s 00:00
在源端和目标端创建xtt.properties文件参数配置的目录
1.2、目标端数据库
源端数据库testdb,数据库版本11.2.0.4.0,运行在Linux x86 64-bit
[oracle@testdb1 ~]$ env | egrep "ORACLE_SID|ORACLE_HOME"
ORACLE_SID=testdb1
ORACLE_HOME=/testdb/ordb/oracle/product/112
SQL> select * from v$version where banner like '%Database%';
BANNER
-------------------------------------------------------------------------------
Oracle Database 11g Enterprise EditionRelease 11.2.0.4.0 - 64bit Production
SQL> select name, platform_id, platform_name from v$database;
NAME PLATFORM_ID PLATFORM_NAME
--------- ----------- --------------------
TESTDB 13 Linux x86 64-bit
需要注意的是源端数据库和目标端数据库字符集必须一致。
源端:
SYS@testdb1 > select PARAMETER, VALUE
2 from v$nls_parameters
3 where PARAMETER in ('NLS_CHARACTERSET','NLS_NCHAR_CHARACTERSET');
PARAMETER VALUE
--------------------------------------------------
NLS_CHARACTERSET ZHS16GBK
NLS_NCHAR_CHARACTERSET UTF8
目标端:
SQL> select PARAMETER, VALUE
2 from v$nls_parameters
3 where PARAMETER in ('NLS_CHARACTERSET','NLS_NCHAR_CHARACTERSET');
PARAMETER VALUE
------------------------------------------------------------
NLS_CHARACTERSET ZHS16GBK
NLS_NCHAR_CHARACTERSET UTF8
在目标端创建到源端的database link TTSLINK:
SQL> create public database link ttslink connect to systemidentified by oracle_test using 'source';
Database link created.
SQL> select * from dual@ttslink;
D
-
X
在目标端为DBMS_FILE_TRANSFER创建目录DESTDIR,其路径为目标端数据库数据文件路径
SQL> create directory destdir as '+DATA_SB/dest/datafile';
Directory created.
SQL>
如下为oracle用户设置TMPDR环境变量
export TMPDIR=/home/oracle/tts
2、数据文件传输阶段
本阶段XTTSTEST表空间的数据文件将从源端数据库传输到目标端数据库,字节转换由DBMS_FILE_TRANSFER包自动完成,本步骤只需要执行一次,数据文件传输过程中不影响源端数据库正常访问。
在源端以oracle用户登录,并设置数据库和TMPDIR变量。
2.1. 源端创建传输脚本
运行 'perl xttdriver.pl -S':
db1:/home/oracle$cd $TMPDIR
db1:/home/oracle/tts$$ORACLE_HOME/perl/bin/perl xttdriver.pl -S

--------------------------------------------------------------------
Done with prepare phase
--------------------------------------------------------------------
本步骤将在当前目录(TMPDIR)生成如下文件
1. xttplan.txt - containing the tablespacenames, their current SCNs and their datafile numbers:
db1:/home/oracle/tts$cat xttplan.txt
XTTSTEST::::15718791765461
41
2. xttnewdatafiles.txt - containing thetablespace names, datafile numbers, the destination directory object name and thesource filenames:
db1:/home/oracle/tts$catxttnewdatafiles.txt
::XTTSTEST
41,DESTDIR:/xttstest.362.959887907
3. getfile.sql - The PL/SQL script(formatting ours) that will be used at the destination to get the datafilesfrom the source:
db1:/home/oracle/tts$cat getfile.sql
0,SOURCEDIR,xttstest.362.959887907,DESTDIR,xttstest_362_959887907
4. xttpreparesrc.sql - the PL/SQL scriptused to create the files in this step.
5. xttprepareNaNd - the command script(empty at this step).
2.2. 传输数据文件到目标端
在目标端以oracle用户登录,并设置环境变量。
[oracle@testdb1 ~]$ env | egrep "ORACLE_SID|ORACLE_HOME"
ORACLE_SID=dest1
ORACLE_HOME=/testdb/ordb/oracle/product/112
从源端拷贝xttnewdatafiles.txt 和 getfile.sql到目标端
[oracle@testdb1 tts]$ scp x.x.x.3:/home/oracle/tts/xttnewdatafiles.txt.
The authenticity of host 'x.x.x.3 (x.x.x.3)'can't be established.

3. 增量更新备份阶段
增量更新备份是通过RMAN增量备份来实现的。不过该阶段增量备份是通过DBMS_FILE_TRANSFER.GET_FILE来实现的,而不是RMANBACKUP AS COPY。本阶段增量备份在源端数据库创建,然后传输到目标端数据库,最后与第二阶段传输过来的数据文件进行合并。
这个阶段中的步骤可以运行多次,以使目标中的datafiles更接近源文件的时间/ SCN。在此阶段,源数据库完全可访问。
3.1. 源端数据库创建增量备份
在源端数据库以oracle用户登录,并设置环境变量,执行'xttdriver.pl -i':
db1:/home/oracle/tts$$ORACLE_HOME/perl/bin/perl xttdriver.pl -i

本步骤在当前目录(TMPDIR)创建如下文件:
1. tsbkupmap.txt - containing thetablespace names, datafile numbers and the incremental backup pieces:
db1:/home/oracle/tts$cat tsbkupmap.txt
XTTSTEST::41:::1=k8sjfjqs_1_1
2. incrbackups.txt - containing the actuallocation of the incremental backup pieces:
db1:/home/oracle/tts$cat incrbackups.txt

3. rmanincrNaNd - containing the RMANscripts used to create the incremental backups.
4. xttdetnewfromscnsrc.sql - the PL/SQLscript used to create the files in this step
5. xttplan.txt.new- after the first run of'xttdriver.pl -i' this is just a copy of the xttplan.txt
3.2. 传输增量备份至目标端
传输增量备份至目标端的stageondest目录
db1:/home/oracle/tts$scp `cat incrbackups.txt` x.x.x.81:/home/oracle/stage_dest

3.3. 在目标端应用增量备份
在目标端以oracle用户登录,并设置环境变量。从源端拷贝xttplan.txt 和 tsbkupmap.txt文件。
[oracle@testdb1 ~]$ cd $TMPDIR
[oracle@testdb1 tts]$ scp x.x.x.3:/home/oracle/tts/xttplan.txt .

--------------------------------------------------------------------
“Can't locate DBI.pm in @INC”错误是可以忽略的,这是由于Perl pragma在asmcmdcore中使用“严格模式”的结果。
本步骤增量备份会被放在备份目标目录并和数据文件副本进行合并,本操作会重启数据库,在RAC环境中只启动目标端一个数据库实例。
可以在备份目标目录查看备份数据:
grep ^backupondest xtt.properties
backupondest=+fra_sb
ASMCMD> ls
nnndn0_0.256.959966091
nnndn0_0.257.959966945
ASMCMD> pwd
+fra_sb/dest/backupset/2017_11_13
3.4. 确定下次增量备份的起始SCN
源端以oracle用户登录,并设置环境变量,执行'xttdriver.pl -s'
$ORACLE_HOME/perl/bin/perl xttdriver.pl -s
Prepare newscn for Tablespaces: 'XTTSTEST'
New /home/oracle/tts/xttplan.txt with FROMSCN's generated
本步骤原来的xttplan.txt会被备份为xttplan.txt<timestamp>,起始SCN会被记录在xttplan.txt,如有需要执行'xttdriver.pl -i'进行下一次增量备份。
第三阶段可以多次执行,每次执行需要运行'xttdriver.pl -i',拷贝增量备份文件、xttplan.txt和tsbkupmap.txt到目标端,在目标端运行'xttdriver.pl -r',最后在源端运行'xttdriver.pl -s'。
本次操作不重复执行阶段3,直接执行阶段4.
4. 完成表空间传输阶段
本阶段源端数据文件为只读模式,目标端数据文件通地创建合并最终增量备份与源端数据文件保持一致。最后传输表空间元数据并导入到目标端数据库。源端数据库表空间置为只读模式直到本阶段完成。
4.1、设置表空间为READ ONLY
在源端以oracle用户登录,并设置环境变量,把XTTSTEST表空间设置为READ ONLY模式。
SYS@testdb1 > alter tablespace xttstest read only;
Tablespace altered.
4.2. 最后增量备份
源端:
$ORACLE_HOME/perl/bin/perl xttdriver.pl -i
$scp `cat incrbackups.txt` x.x.x.81:/home/oracle/stage_dest
目标端:
[oracle@testdb1 tts]$ scp x.x.x.3:/home/oracle/tts/xttplan.txt.
oracle@x.x.x.3's password:
xttplan.txt 100% 32 0.0KB/s 00:00
[oracle@testdb1 tts]$ scp x.x.x.3:/home/oracle/tts/tsbkupmap.txt .
oracle@x.x.x.3's password:
tsbkupmap.txt 100% 30 0.0KB/s 00:00
[oracle@testdb1 tts]$
4.3. 最后增量备份合并
[oracle@testdb1 tts]$ $ORACLE_HOME/perl/bin/perl xttdriver.pl -r
