[求释疑]OGG的roll over操作

Wizard

今天发现ogg的同步过程lag超过12个小时，查看目标端replicat一直在处理，对比目标端与源端的trail文件，发现源端470m, 目标端已经接近1G，查看源数据库，昨晚的批量更新操作已经结束，但是目标端还在应用trail文件。
查看源端log，发现记录如下：

2013-05-02 01:51:30  INFO    OGG-01026  Oracle GoldenGate Capture for ODBC, EMSS03.prm:  Rolling over remote file ./dirdat/z3000000.
.
.
. (略去78个）
.

2013-05-02 01:52:19  INFO    OGG-01026  Oracle GoldenGate Capture for ODBC, EMSS03.prm:  Rolling over remote file ./dirdat/z3000080.

然后接着roll over pump
2013-05-02 01:51:30  INFO    OGG-01026  Oracle GoldenGate Capture for ODBC, PUMP03.prm:  Rolling over remote file ./dirdat/z3000000.
.
.
. (略去78个）
.

2013-05-02 01:52:05  INFO    OGG-01026  Oracle GoldenGate Capture for ODBC, PUMP03.prm:  Rolling over remote file ./dirdat/z3000024.

所以源端只有80个trail文件，但是目标端已经超过130，还在增长。
从目前的分析看，是transaction roll back导致了lag，但是不是很清楚ogg的roll over的机制，是如何产生log的，请刘大解释一下吧？

Repliate report 全部都是下面的记录， 依次切换至82号trail

Switching to next trail file ./dirdat/z3000003 at 2013-05-02 01:54:45 due to EOF, with current RBA 9999974
