1.1.2. 編輯文件添加參數

GGSCI (cndba) 20> edit params mgr GGSCI (cndba) 25> view params mgrport 7809 PURGEOLDEXTRACTS ./dirdat/et*, USECHECKPOINTS, MINKEEPHOURS 1 參數說明：定期清理dirdat路徑下的本地隊列（local trail）。保留期限一個小時，過期后自動刪除。從而控制隊列文件的目錄不會增長過大。

1.1.3. 啟動mgr進程

GGSCI (cndba) 21> start mgrManager started.GGSCI (cndba) 24> info allProgram Status Group Lag at Chkpt Time Since ChkptMANAGER RUNNING EXTRACT RUNNING EXT1 00:00:00 00:00:01 EXTRACT RUNNING PUMP1 00:00:00 00:00:04

1.1.4. 查看源端tail 文件

--配置參數前 [root@www.cndba.cn dirdat]# ll total 21524 -rw-rw-rw- 1 oracle oinstall 1405 Jun 7 16:11 et000000 -rw-rw-rw- 1 oracle oinstall 1016 Jun 7 16:19 et000001 -rw-rw-rw- 1 oracle oinstall 21989956 Jun 7 22:13 et000002 -rw-rw-rw- 1 oracle oinstall 1075 Jun 8 11:18 et000003 -rw-rw-rw- 1 oracle oinstall 2513 Jun 8 18:28 et000004 -rw-rw-rw- 1 oracle oinstall 1416 Jun 8 19:17 et000005 -rw-rw-rw- 1 oracle oinstall 1442 Jun 11 09:16 et000006 -rw-rw-rw- 1 oracle oinstall 1779 Jun 11 09:16 et000007 -rw-rw-rw- 1 oracle oinstall 1175 Jun 9 02:20 ex000000 -rw-rw-rw- 1 oracle oinstall 1322 Jun 9 02:49 ex000001 -rw-rw-rw- 1 oracle oinstall 2513 Jun 9 03:01 ex000002 -rw-rw-rw- 1 oracle oinstall 1350 Jun 9 03:05 ex000003 --配置參數后 [root@www.cndba.cn dirdat]# ll total 36 -rw-rw-rw- 1 oracle oinstall 1416 Jun 8 19:17 et000005 -rw-rw-rw- 1 oracle oinstall 1442 Jun 11 09:16 et000006 -rw-rw-rw- 1 oracle oinstall 1779 Jun 11 10:07 et000007 -rw-rw-rw- 1 oracle oinstall 1075 Jun 11 10:07 et000008 -rw-rw-rw- 1 oracle oinstall 1175 Jun 9 02:20 ex000000 -rw-rw-rw- 1 oracle oinstall 1322 Jun 9 02:49 ex000001 -rw-rw-rw- 1 oracle oinstall 2513 Jun 9 03:01 ex000002 -rw-rw-rw- 1 oracle oinstall 1350 Jun 9 03:05 ex000003

1.2. 目標端操作

1.2.1. 停止mgr進程

GGSCI (cndba) 2> stop mgr Manager process is required by other GGS processes. Are you sure you want to stop it (y/n)? ySending STOP request to MANAGER ... Request processed. Manager stopped.

1.2.2. 編輯文件添加參數

GGSCI (cndba) 4> edit params mgrGGSCI (cndba) 5> view params mgrport 7809 PURGEOLDEXTRACTS ./dirdat/et*, USECHECKPOINTS, MINKEEPHOURS 1

1.2.3. 啟動mgr進程

GGSCI (cndba) 6> start mgrManager started.GGSCI (cndba) 7> info allProgram Status Group Lag at Chkpt Time Since ChkptMANAGER RUNNING REPLICAT RUNNING REP1 00:00:00 00:00:04

1.2.4. 查看目標端tail文件

----配置參數前 [oracle@www.cndba.cn ogg]$ cd dirdat [oracle@www.cndba.cn dirdat]$ ll total 21500 drwxr-xr-x 2 root root 4096 Jun 8 11:21 backup -rw-rw-rw- 1 oracle oinstall 1444 Jun 7 16:11 et000000 -rw-rw-rw- 1 oracle oinstall 0 Jun 7 16:19 et000001 -rw-rw-rw- 1 oracle oinstall 21989995 Jun 7 22:14 et000002 -rw-rw-rw- 1 oracle oinstall 1209 Jun 8 11:19 et000003 -rw-rw-rw- 1 oracle oinstall 2682 Jun 11 09:16 et000004 -rw-rw-rw- 1 oracle oinstall 1793 Jun 11 10:07 et000005 -rw-rw-rw- 1 oracle oinstall 1314 Jun 11 10:07 et000006 --配置參數后 [oracle@www.cndba.cn dirdat]$ ll total 12 drwxr-xr-x 2 root root 4096 Jun 8 11:21 backup -rw-rw-rw- 1 oracle oinstall 1793 Jun 11 10:07 et000005 -rw-rw-rw- 1 oracle oinstall 1314 Jun 11 10:07 et000006

1.3. 補充說明

因為測試這里保留1個小時的tail文件， 保留期限7天的tail文件，過期后自動刪除 PURGEOLDEXTRACTS ./dirdat/et*, USECHECKPOINTS,MINKEEPDAYS 7 只保留一個處理過的隊列文件（不建議使用） PURGEOLDEXTRACTS /ggs/dirdat/AA*, USECHECKPOINTS, MINKEEPFILES 1 PURGEOLDEXTRACTS /ggs/dirdat/AA*, USECHECKPOINTS, MINKEEPHOURS 4, &MINKEEPFILES 4 如果MINKEEPHOURS ，MINKEEPDAYS ，MINKEEPFILES 同時使用，如果發生沖突時，那么系統接受MINKEEPHOURS和MINKEEPDAYS 參數將對MINKEEPFILES 參數做忽略。
