如果要使用 logdump 的话，需要知道进程正在处理的文件，如何获取这个文件呢？
对于抽取进程来说：
1. 操作系统上最后一个 trail 文件一定是 abended 时正在处理的文件
2. 通过命令查看 info < 进程名 >,detail
对于复制进程来说，操作系统最后一个文件不一定是 replicat 进程正在处理的文件了：
1.info < 进程名 >
2.info < 进程名 >,detail
查看复制进程当前处理的文件和处理到的 RBA 地址

(x03) 单条事务

看到 TransInd : . (x02)
说明这是该事务的最后一条
下一个事务或者 DDL ：

可以看到当前 TransInd 是 (x03) ，说明上个事务结束后，新事务是一个单条事务，这个事务的 RBA 就是我们在寻找的 extrba 的值
当前打开的是 /u01/app/oracle/products/ogg/dirdat/pump_mi01/p1000000012 ，所以 extseqno 是 12

这样就跳过了上一个有问题的事务。
