GoldenGate-增加datadump的数据同步

1.在GolddenGate文章中，如果网络断开的话，在目标机器上并不能生成trail文件，因此就会出现错误。

2011-04-23 17:44:16  ERROR   OGG-01033  There is a problem in network communication, a remote file problem, encryption keys f
or target and source do not match (if using ENCRYPT) or an unknown error. (Remote file used is ./dirdat/ma000001, reply recei
ved is Unable to lock file "./dirdat/ma000001" (error 11, Resource temporarily unavailable).  Lock currently held by process
id (PID) 9556.).

 

2.为了解决以上问题，特增加datadump进程，通过此进程把trail文件先放在本地，待网络畅通后，再传到目标机器的响应文件夹下。

 

3.添加数据抽取进程

  add extract load1, translog, begin now

 

4.配置本地数据抽取文件位置及抽取进程

  add exttrail ./dirdat/ex, extract load1, megab
