1. OGG mgr定期清理tail 文件
1.1. 源端操作
1.1.1. 停止mgr进程
GGSCI (cndba) 14> stop mgr
Manager process is required by other GGS processes.
Are you sure you want to stop it (y/n)? y
Sending STOP request to MANAGER ...

Manager stopped.
GGSCI (cndba) 15> info all

MANAGER STOPPED
EXTRACT RUNNING EXT1 00:00:00 00:00:02
EXTRACT RUNNING PUMP1 00:00:00 00:00:05
1.1.2. 编辑文件添加参数
GGSCI (cndba) 20> edit params mgr
GGSCI (cndba) 25> view params mgr
port 7809
PURGEOLDEXTRACTS ./dirdat/et*, USECHECKPOINTS, MINKEEPHOURS 1
参数说明：定期清理dirdat路径下的本地队列（local trail）。保留期限一个小时，过期后自动删除。从而控制队列文件的目录不会增长过大。
1.1.3. 启动mgr进程
GGSCI (cndba) 21> start mgr
Manager started.
GGSCI (cndba) 24> info all
Program Status Group Lag at Chkpt Time Since Chkpt

1.3. 补充说明
因为测试这里保留1个小时的tail文件，
保留期限7天的tail文件，过期后自动删除
PURGEOLDEXTRACTS ./dirdat/et*, USECHECKPOINTS,MINKEEPDAYS 7
只保留一个处理过的队列文件（不建议使用）
PURGEOLDEXTRACTS /ggs/dirdat/AA*, USECHECKPOINTS, MINKEEPFILES 1
PURGEOLDEXTRACTS /ggs/dirdat/AA*, USECHECKPOINTS, MINKEEPHOURS 4, &MINKEEPFILES 4
如果MINKEEPHOURS ，MINKEEPDAYS ，MINKEEPFILES 同时使用，如果发生冲突时，那么系统接受MINKEEPHOURS和MINKEEPDAYS 参数将对MINKEEPFILES 参数做忽略。
