OGG抽取进程异常问题排查一例
1、问题现象
抽取进程常常running，但是没有新产生trail文件，lag比较大
GGSCI (xxxdb) > info all

2、问题解决
通过 info ext1 showch 查看抽取进程的Recovery Checkpoint，设置抽取进程到相应时间
GGSCI (xxxdb) > alter extract EXT1 ,tranlog ,begin -- ::
EXTRACT altered. GGSCI (xxxdb) > start EXT1 Sending START request to MANAGER ...
EXTRACT EXT1 starting GGSCI (xxxdb) > info EXT1 EXTRACT EXT1 Initialized -- : Status RUNNING
