故障现象
客户反馈传输进程abended，查看日志发现是trail文件中的事务记录损坏，日志如下：
2025-05-13T08:13:30.516+0800 ERROR OGG-02171 Oracle GoldenGate Capture for Oracle, p2_md.prm: Error reading LCR from data source. Status 509, data source type 0. 2025-05-13T08:13:30.517+0800 ERROR OGG-02191 Oracle GoldenGate Capture for Oracle, p2_md.prm: Incompatible record 101 in /exptbk/odc/oggapp/dirdat/ms000006546, rba 483,188,832 when getting trail header. 2025-05-13T08:13:30.517+0800 ERROR OGG-01668 Oracle GoldenGate Capture for Oracle, p2_md.prm: PROCESS ABENDING“Incompatible record”是指遇到不完整的记录，记录损坏，对于这类错误没有简单快速就能恢复的方法，处理不当还可能丢失记录，需要重新从源端同步以保持数据一致。
处理思路
情况一：如果源trail文件是好的，即trail文件是由传输进程写入的，只是目标端的trail文件损坏，导致应用进程异常，则可以停止传输和应用进程，并更改传输进程到失败点之前，然后重新发送trail文件，供应用进程使用；
情况二：如果源trail文件损坏，即trail文件是由挖掘进程写入的，导致传输进程读取并发送是异常，则可以跳过该错误事务并从下一个正常的事务开始发送，或者停止挖掘进程并找到错误点之前的scn号，更改挖掘进程到失败点之前，重新挖掘，传输进程从重挖之后的trail文件开始发送。
本次故障，我们属于情况二，即源trail文件已经损坏，所以对于情况一的处理方法，我们这里就简单讲下步骤，主要对情况二做详细描述及处理。
情况一处理方法
1.停止传输和应用进程
2.记下应用进程的上次应用的 SCN 和时间戳;
3.更改传输进程点，用于重新读取该 SCN 后的数据并发送，启动传输进程（可以往前多指定点也没关系）;
4.更改应用进程以上次记录的scn后开始应用，启动应用进程；
从ogg12.2开始，针对这种情况有了更方便的处理方法，一般步骤如下：
1.停止传输和应用进程。
2.删除或重命名损坏文件开始及之后的所有trail文件。
3.在源中启动 传输进程，传输进程会自动重建丢失的trail文件。
4.启动应用进程。
下面我们具体讲下本次故障处理方法（即情况二）。
前面我们也大致提到针对这种情况有两种处理方式，一种是定位到损坏点之前的scn号，并重新挖掘和传输，难点在于这个scn号的定位；另一种是直接跳过损坏的事务从下一个正常事务开始做传输，这个方法虽然能快速恢复进程，但问题是会造成少量事务不一致，为保证数据一致，后续需要做比对修复或者重新初始化。这次我们为确保数据不丢失，选择重新挖掘。
1.定位损坏点scn号
需要借助logdump工具
