手工迁移数据库Oracle 11.2.0.4到新机器并升级到12.2.0.1版本

前言
在最近的项目里，客户有2套11.2.0.4的数据库，需要迁移上云，数据量较大（一个600g，一个2T），停机时间6小时以内，还有很多其它的库需要同时切割，目前想到的迁移方案有：
1、XTTS进行全量+增量迁移。
缺点：物理迁移，在最后一次增量的时候，源端数据库需要设置为只读模式，只能读，不能写。云端数据库在最后一次增量之前都不能使用。
由于客户需要提前做POC测试，而且网络不是直达的，需要经过中转机，所以，该方案放弃。
2、使用数据泵+OGG方式。
缺点：逻辑迁移，对于特殊的列不能同步（例如long列），需要正式切割前进行大量的实验观察，否则可能造成个别数据不一致。
这个方案，我想着使用OGG的微服务会比较好，结果安装了好几个版本的OGG微服务（从12.3到21.3），兼容性都不支持11.2.0.4，无奈只能放弃！
3、进行全量+增量的rman备份恢复，最后做数据字典升级。可以使用手动脚本升级，也可以使用DBUA升级，也可以使用最新的AutoUpgrade工具升级。
缺点：数据字典升级时间稍微长点，预估1~2小时左右，但可控在切割时间内。
优点：方案成熟，变数少，可以做压缩备份，减少中间网络传输的时间。
本文我们使用方案3来做演练。

使用rman全备+增备+dbupgrade成功异机升级到12.2.0.1.
总结
1、如果在原Oracle 11g数据库系统中，有使用WM_CONCAT函数，那么在升级到12c后会报错：ORA-00904: "WM_CONCAT": invalid identifier，解决办法请参考：https://www.xmmup.com/ora-00904-wm_concat-invalid-identifiercuowujiejue.html
2、只有在编译失效对象完成后，dba_registry中的statu列才会变为VALID。若编译过程很慢，那您得找一下原因了，找找是否有大量存储过程，而存储过程中含有dblink连接等问题，等这些问题修复后，再编译起来就很快了。编译脚本：
1 2 3 4 5 6 | -- 编译失效对象 select count(1) from dba_objects where status='INVALID'; @$ORACLE_HOME/rdbms/admin/utlrp.sql SELECT 'ALTER '|| d.object_type|| ' ' || d.owner ||'.'|| d.object_name ||' COMPILE;' FROM dba_objects d where d.status='INVALID' ; |
文中所说的数据泵+ogg方式其实是可行的，不能使用微服务，但是可以使用传统模式，请参考 https://www.xmmup.com/shiyongogg-21-3yuanchengshishihuxiangtongbuoracle-11-2-0-4shuangzhu.html
这个升级，目标机器12C 中没有PDB，只有CDB吧？
是的，是非cdb的库，和11架构一样
