1.初始化设置阶段
1.2识别要被传输的表空间
1.3在源系统上安装xttconvert脚本
1.4 创建需要使用的目录
源数据库目录对象引用源数据库中当前存放数据文件的目录。例如，下面创建目录对象指向，数据文件存放目录+DATA/ORCL/DATAFILE/，连接到源数据库房执行以下命令:
目标数据库目录对象引用目标数据库中将要存储数据文件的目录。这个目录是最终目标数据库将要存放数据文件的目录+DATA/jy/4B2C6373AE2547CCE053AB828A0A7CA3/datafile/，连接到目标数据库执行以下命令要注意的是目录对象与dblink要在CDB中创建
在目标数据库中创建一个dblink连接到源数据库。例如创建一个名叫ttslink的dblink，执行以下命令:
在源系统中创建目录/ora_xtts/backupformat用来存储源系统中对源数据库生成的备份及增量备份文件，xtt.properties文件中的backupformat参数设置该目录。
在目标系统中创建目录/tts/backup用来存储手动从源系统中传输过来的备份及增量备份文件，xtt.properties文件中的stageondest参数设置该目录。
xtt.properties文件中的storageondest参数设置目标数据库最终存储数据文件的目录，这里是
1.5在源系统中配置xtt.properties文件
1.6将源系统中的xttconvert脚本与xtt.properties文件复制到目标系统中
1.7设置环境变量TMPDIR
源系统
目标系统
2.准备阶段
2.1在源系统中对要传输的表空间生成备份
要被传输的一组表空间必须是online，read write状态且不包含脱机数据文件。如果在源数据库中被传输表空间的一个或多个数据文件是脱机状态或read only就会触发错误。如果表空间在整个表空间传输过程中都保持read only状态，那么就使用传统的跨平台传输表空间，不要使用跨平台增量备份传输表空间。
2.2 传输数据文件到目标系统中
3.前滚阶段
在这个阶段会在源系统中对源数据库创建增量备份，将增量备份文件传输到目标系统并转换为目标系统所使用的字节序，然后将转换后的增量备份应用到数据文件。这个阶段的操作可以执行多次。每一次成功的增量备份所花的时间要比上一次的少，这将使用目标数据库中的数据文件的内容更接近源数据库的内容。在执行这个阶段操作时被传输的数据完全可以被访问。
3.1 在源系统中对被传输的表空间LDJC,CDZJ创建增量备份
上面的操作会执行RMAN命令对xtt.properties文件中所指定的所有表空间生成增量备份文件。并且还将创建以下文件供后面的操作使用:
tsbkupmap.txt的内容如下:
文件中的内容记录了表空间与增量备份的关联关系
incrbackups.txt的内容如下:
文件中的内容显示了生成的增量备份文件信息
3.2 将增量备份传输到目标系统中
3.3 在目标系统中转换增量备份并应用到数据文件副本
这步前滚数据文件的操作，会以sys用户连接到增量转换实例，转换完增量备份后，然后连接到目标数据库并将增量备份应用到每个表空间注意：对于每一次增量备份都需要将xttplan.txt与tsbkupmap.txt文件复制一次，不要对脚本所生成的xttplan.txt.new文件进行修改，复制或者其它任何改变。执行这步操作时目标实例会进行重启操作。
3.4 为下一次增量备份判断from_scn
在源系统中，以Oracle软件用户登录并设置环境变量(ORACLE_HOME与ORACLE_SID)来指向源数据库，执行以下命令来判断from_scn:
4.传输阶段
4.1 将源数据库中被传输表空间设置为read only状态
4.2 最后一次创建增量备份，并传输到目标系统且执行转换并应用到目标数据文件
上面的操作会执行RMAN命令对xtt.properties文件中所指定的所有表空间生成增量备份文件。并且还将创建以下文件供后面的操作使用:
tsbkupmap.txt的内容如下:
文件中的内容记录了表空间与增量备份的关联关系
incrbackups.txt的内容如下:
文件中的内容显示了生成的增量备份文件信息
将增量备份传输到目标系统中
在目标系统中转换增量备份并应用到数据文件副本
4.3 在目标数据库中导入元数据
上面的命令会生成一个名叫xttplugin.txt的文件，文件创建了一个使用network_link参数执行传输表空间导入元数据的命令。命令中的transport_tablespaces与transport_datafiles参数已经设置正确。注意network_link模式指示导入通过使用dblink来完成，就不需要执行导出或使用dump文件。如果选择执行这个命令来完成表空间的传输就需要修改directory,logfile与network_link参数
在目标数据库中创建用户方案jy
5.验证传输数据
5.2将目标数据库中的表空间JY修改为read write状态
6.清除操作
xttdriver.pl脚本选项
--restore:在目标系统中还原并转换stageondest目录中的数据文件备份的副本。还原的文件将会存储到storageondest参数所指定的目录中
--bkpincr:在源系统中对表空间创建增量备份并存储在backupformat参数所指定的目录中。这步操作还会创建incrbackups.txt文件它列出了所创建的备份。这个文件与tsbkupmap.txt必须复制到目标系统中的stageondest参数所指定的目录中
-recover:将增量备份应用到已经还原的数据文件上
-s:对源数据库判断新的from_scn可以执行一次或多次。这个操作将会计算下一个from_scn，并记录在xttplan.txt文件中，然后使用创建增量备份时会使用。
-bkpexport:将执行最后一次增量备份并且会创建元数据的dump文件用来导入数据文件。增量备份将会存储在backupformat参数所指定的目录中并且会创建incrbckups.txt与tsbkupmaps.txt文件，这些都要复制到目标系统中
--resincrdmp:将恢复最后一次增量备份并应用到数据文件。同时dump文件会被还原到TMPDIR变量所指定的目录中，dump文件可以用来导入
-e:在目标系统中生成传输表空间要导入的元数据脚本
-d debug:为了以debug模式来执行xttdriver.pl 与RMAN脚本。也可以设置环境变量XTTDEBUG=1，debug级别可以为1,2,3,例如xttdriver.pl -3
xtt.properties文件参数说明
platformid:从v$database.platform_id获得的源数据库的platform id，例如platformid=13
backupformat:源系统中存储备份文件的目录。这个目录必须要有足够的空间来存储所有创建的备份与增量备份文件。这个目录可以是目标系统上通过NFS-mounted文件系统所挂载到源系统中的一个目录，在这种情况下，目标系统中的stageondest参数也引用这个相同的NFS目录。例如，backupformat=/stage_source
stageondest:目标系统中存储从源系统中手动传输过来的数据文件副本。这个目录要有足够的空间来存储数据文件副本。这个目录同时也是用来存储从源系统传输过来的增量备份文件的目录。在目标系统上执行xttdriver.pl -c转换数据文件与执行xttdriver.pl -r前滚数据文件时会从这个目录中读取数据文件副本与增量备份文件。这个目标也可以是一个DBFS-mounted文件系统。个目录可以是源系统上通过NFS-mounted文件系统所挂载到目标系统中的一个目录，在这种情况下，源系统中的backupformat参数与dfcopydir参数就会引用这个相同的NFS目录。可以参考See Note 359515.1 for mount option guidelines。例如stageondest=/stage_dest
storageondest:目标系统中用来存储xttdriver.pl -c转换操作后所生成的数据文件副本的目录，也就是目标数据库最终存储数据文件的目录。这个目录要有足够的空间来永久存储数据文件。这个参数当使用RMAN备份来生成初始化数据文件副本时才使用，例如
asm_home:目标系统中ASM实例的ORACLE_HOME。注意如果backupondest设置为文件系统目录，那么就要删除asm_home与asm_sid参数，例如asm_home=/u01/app/11.2.0.4/grid
asm_sid:目标系统中ASM实例的ORACLE_SID。例如asm_sid=+ASM1
parallel:定义rmanconvert.cmd命令文件中rman convert命令的并行度。如果不设置这个参数，那么xttdriver.pl将使用parallel=8的缺省并行度。例如，parallel=3
1.1安装目标数据库软件并创建目标数据库
在目标系统上安装目标Oracle数据库软件，版本应该为Oracle12c,操作系统是Linux,我这里都是12.2.0.1。在源数据库中创建了一个要被传输到目标数据库的表空间jy，用户方案jy，源数据库版本也是12.2.0.1,操作系统是Linux。
源数据库中要被传输的表空间为jy，用户方案jy。

.在目标数据库中创建一个dblink连接到源数据库

在源系统与目标系统中设置环境变量TMPDIR。使用shell来执行Perl脚本xttdriver.pl所生成的文件会存储在$TMPDIR目录中，如果没有设置TMPDIR环境变量，那么生成的文件会存储在/tmp目录中。
[oracle@jytest3 ora_xtts]$ export TMPDIR=/ora_xtts/xtts_script
[oracle@jytest1 tts]$ export TMPDIR=/tts/xtts_script
在准备阶段，要被传输的表空间会在源系统中生成备份，然后将备份传输到目标系统中，并通过执行xttdriver.pl脚本将备份还原。注意，对于要传输大量数据文件，可以使用dbms_file_transfer进行传输(可以参考文档 1389592.1中的准备阶段)会要比手动传输备份文件到目标系统中快很多。这种方法也适用于Oracle 12c,11G - Reduce Transportable Tablespace Downtime using Cross Platform Incremental Backup (Doc ID 1389592.1).
在源系统中，以oracle软件用户登录，并设置环境变量(ORACLE_HOME与ORACLE_SID)来指向源数据库，执行以下命令来生成备份
[oracle@jytest3 xtts_script]$ export ORACLE_HOME=/u01/app/oracle/product/12.2.0/db

在执行传输阶段操作时，源数据库中被传输表空间要设置为read only状态，并且通过创建与应用最后一次的增量备份使用目标数据库中的数据文件与源数据库中的数据文件内容保持一致。在目标数据库数据文件与源数据库数据文件内容达成一致后，在源系统中执行正常的传输表空间操作来导出元数据，然后将元数据导入到目标数据库中。直到传输阶段操作完成之前，被传输的数据只能以read only模式被访问。
在源系统中，以Oracle软件用户登录并设置环境变量(ORACLE_HOME与ORACLE_SID)来指向源数据库，并执行以下命令将表空间设置为read only:
SQL> alter tablespace jy read only;

Tablespace altered.
如果使用单独的转换home与实例，那么可以关闭转换实例并删除转换home。还可以删除源系统中创建的backupformat目录，目标系统中创建的bacup目录，源系统与目标系统中设置的环境变量$TMPDIR。
--backup:对源数据库中要被传输的表空间创建level 0级备份。这些备份将被写到xtt.properties文件中backupoformat参数所指定的目录中。这些备份需要手动复制到目标系统中stageondest参数所指定的目录中。而且还会生成tsbkupmap.txt与xttnewdatafiles.txt文件并且也需要复制到目标系统中相应目录(TMPDIR变量所指向的目录)
tablespaces:用逗号来分隔从源数据库要被传输到目标数据库的表空间列表，例如tablespaces=TS1,TS2
storageondest=+DATA或者storageondest=/oradata/test
