在Oracle社區可以搜索到這樣的問題：
How to change oswatcher retention when running under TFA
但很遺憾該問題目前也沒有給出確切答復。
其實提問者已經給出了修改方法：
tfactl stop oswbb
tfactl start oswbb 15 168
只是不確認這樣的修改在下次主機重啟后是否還生效？下面來驗證一下：
首先，默認的osw采集間隔是30s，保存時間為48h：
[grid@db01 ~]$ ps -ef|grep osw
grid 8378 1 0 Jun27 ? 00:01:11 /bin/sh ./OSWatcher.sh 30 48 NONE /opt/app/grid/oracle.ahf/data/repository/suptools/db01/oswbb/grid/archive
grid 8961 8378 0 Jun27 ? 00:00:27 /bin/sh ./OSWatcherFM.sh 48 /opt/app/grid/oracle.ahf/data/repository/suptools/db01/oswbb/grid/archive
grid 11868 11846 0 23:34 pts/0 00:00:00 grep --color=auto osw
我們將其修改為采集間隔15s，保存時間為168h(也就是7天)：
tfactl stop oswbb
tfactl start oswbb 15 168
[grid@db01 ~]$ tfactl stop oswbb
Stopped OSWatcher
[grid@db01 ~]$ tfactl start oswbb 15 168
Starting OSWatcher
[grid@db01 ~]$ ps -ef|grep osw
grid 12123 1 0 23:34 pts/0 00:00:00 /bin/sh ./OSWatcher.sh 15 168 NONE /opt/app/grid/oracle.ahf/data/repository/suptools/db01/oswbb/grid/archive
grid 12152 11846 0 23:34 pts/0 00:00:00 grep --color=auto osw
[grid@db01 ~]$ ps -ef|grep osw
grid 12123 1 0 23:34 pts/0 00:00:00 /bin/sh ./OSWatcher.sh 15 168 NONE /opt/app/grid/oracle.ahf/data/repository/suptools/db01/oswbb/grid/archive
grid 12241 12123 0 23:34 pts/0 00:00:00 /bin/sh ./OSWatcherFM.sh 168 /opt/app/grid/oracle.ahf/data/repository/suptools/db01/oswbb/grid/archive
grid 12346 11846 0 23:34 pts/0 00:00:00 grep --color=auto osw
下面我們將主機重啟，驗證是否重啟后還生效：
[root@db01 ~]# reboot
[grid@db01 ~]$ uptime
23:47:45 up 9 min, 1 user, load average: 0.45, 0.86, 0.69
[grid@db01 ~]$ ps -ef|grep osw
grid 5976 5940 0 23:47 pts/0 00:00:00 grep --color=auto osw
遺憾的看到，重啟后osw壓根兒都沒有自啟動，更別提保留什么配置了..
查詢下tfactl toolstatus信息如下：
[grid@db01 ~]$ tfactl toolstatus

[grid@db01 ~]$
發現其中oswbb狀態是“NOT RUNNING”，手工啟動oswbb不加參數，發現已經是之前改過的配置：
[grid@db01 ~]$ tfactl start oswbb
Starting OSWatcher
[grid@db01 ~]$ ps -ef|grep osw
grid 8671 1 0 00:07 pts/0 00:00:00 /bin/sh ./OSWatcher.sh 15 168 NONE /opt/app/grid/oracle.ahf/data/repository/suptools/db01/oswbb/grid/archive
grid 8700 5940 0 00:07 pts/0 00:00:00 grep --color=auto osw
看來重啟配置雖然不會丟失，但是oswbb沒有自啟動，需要手工啟動。
