今天由于没有正常的先关闭源端的PUMP进程而直接关闭了备库的replicat和MGR进程。 导致PUMP进程启动不了报错如下： OGG-01496 Oracle GoldenGate Capture for Oracle, py169.prm: Failed to open target trail file ./dirdat/tb000183, at RBA 4434691.
我对PUMP提示使用下一个trail文件 alter extract py169, ETROLLOVER
然后重新启动报错如下：
2014-07-07 14:20:05 INFO OGG-01478 Oracle GoldenGate Capture for Oracle, py169.prm: Output file ./dirdat/tb is using format RELEASE 11.2. 2014-07-07 14:20:05 INFO OGG-01026 Oracle GoldenGate Capture for Oracle, py169.prm: Rolling over remote file ./dirdat/tb000184. 2014-07-07 14:20:26 ERROR OGG-01028 Oracle GoldenGate Capture for Oracle, py169.prm: Incompatible record (101) in ./dirdat/sb000182, rba 48681981 (getting header) 同时我记录了replicat进程的最后SCN Current Checkpoint Detail:

If a trail is not corrupt, a pump or replicat can be restarted by noting the point of failure (trail number and RBA) indicated in the report and discard file. Please do not attempt this if you are not familiar with reading these reports.
This should be done on transaction boundaries or with RESTARTCOLLISIONS enabled. If you do not understand this, do not do this yourself; please have support assist you.
>logdump logdump> log to mycase.txt logdump> open (/ggtrail/GGODSCF/dirdat/cf000325) <<<--- the trail in the report logdump> ghdr on logdump> pos (RBA 19018) <<<--- the RBA in the report logdump> n this will give you a bad header message
logdump> sfh prev this gives you the header of the previous record start,write down the RBA value <<<--- If it's the transaction boundary or only DML in transaction
logdump> count if this finishes Ok and gives you a count of tables and records, the trail is OK and you can use the RBA we saved for the alter later the trail is known to be undamaged if this does not finish with the count, you have a bad trail and must use another recovery method, contact support. logdump> exit
You now have a history of what you did in file mycase.txt and a written record of the RBA to use to ALTER the extract data pump or replicat
