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 ...
Request processed.
Manager stopped.

GGSCI (cndba) 15> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

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

MANAGER     RUNNING                                           
EXTRACT     RUNNING     EXT1        00:00:00      00:00:01    
EXTRACT     RUNNING     PUMP1       00:00:00      00:00:04

GGSCI (cndba) 7> info all

Program     Status      Group       Lag at Chkpt  Time Since Chkpt

REPLICAT    RUNNING     REP1        00:00:00      00:00:04

1.2.4. 查看目标端tail文件

-rw-rw-rw- 1 oracle oinstall 1314 Jun 11 10:07 et000006

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。
