记录一次OGG不同步问题的解决

今天测试ogg的同步，源是Windows，目标是Linux。因为把pump进程里面的路径搞错了，应该是pump到Linux下，对应的是Linux的路径，结果搞成了Windows下的路径。如下

extract pumdb1
SETENV(NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK")
SETENV(ORACLE_SID="test")
userid ggs, password ggs
passthru
rmthost 192.168.2.14,mgrport 7809
--rmttrail d:\ogg\dirdat\db
rmttrail /u01/ogg/dirdat/db
table bb.t1;

复制进程如下： 因为复制进程要在dirdat中找到db开头的文件进行复制。实际上并没有这些文件，因为生成的文件是D:开头的。所以导致不能复制（尽管replicat进程是running的）。

add replicat repdb1,exttrail /u01/ogg/dirdat/db, checkpointtable ggs.checkpoint
start replicat repdb1,aftercsn 1105463

最终的结果，是导致生成的文件，被抛到了目标端的/u01/ogg目录下，而不是/u01/ogg/dirdat目录下。如下。

而且，查看目标端的replicat进程，没有复制任何信息。也就是说，数据没有同步。怎么解决呢。

想了下ogg的原理。既然pump文件都生成了，也抛过来了。 有文件，还是可以继续同步的。

解决方法。将这些D：开头的文件更改名字（在notepad 中统一更改，统一修改好mv格式，然后在Linux下修改），然后这些文件移动到dirdat目录下。 然后重新创建一个复制进程，进行复制，即可。这里重新命名为ab开头的文件，复制进程复制ab开头的文件。

创建一个复制进程repdb2

replicat repdb2
SETENV(NLS_LANG="SIMPLIFIED CHINESE_CHINA.ZHS16GBK")
SETENV(ORACLE_SID="orcl")
userid ggs, password ggs
assumetargetdefs
discardfile /u01/ogg/dirdat/rep_2_discard,append
--handlecollisions
discardfile /u01/ogg/dirrpt/repdb2_repaix.dsc,purge
REPORTROLLOVER AT 05:30 ON Friday
map bb.t1,target bb.t1;
--ddl include all
DDLERROR 10655 IGNORE
DDLERROR 10636 IGNORE
DDLERROR DEFAULT IGNORE RETRYOP

启动复制进程repdb2，重新复制即可。

add replicat repdb2,exttrail /u01/ogg/dirdat/ab, checkpointtable ggs.checkpoint
start replicat repdb2,aftercsn 1105463

END。
