在MOS查找一些问题是， 发现了一个清理日志的脚本，比较好用。 j具体可参考mos文档2081655.1。该脚本具体命令如下：

``` shell
[root@rac19c soft]# ./purgeLogs -h
Usage:
     purgeLogs [ -days <days> [ -aud ] [ -lsnr ] ] |
               [ -orcl <days> [ -aud ] [ -lsnr ] ] |
               [ -tfa <days> ] | 
               [ -osw <days> ] | 
               [ -oda <days> ] | 
               [ -extra '<folder>':<days> | [, '<folder>':<days>] ]
               [ -automigrate ]
               [ -dryrun ]

purgeLogs OPTIONS
      -days  <days>             Purge orcl,tfa,osw,oda components logs & traces older then # days
      -orcl  <days>             Purge only GI/RDBMS logs & traces (Default 30 days)
      -tfa   <days>             Purge only TFA repository older then # days (Default 30 days)
      -osw   <days>             Purge only OSW archives older then # days (Default 30 days)
      -oda   <days>             Purge only ODA logs and trace older then # days (Default 30 days)
      -extra '<folder>':<days>  Purge only files in user specified folders (Default 30 days)
      -aud                      Purge Audit logs based on '-orcl <days>' option
      -lsnr                     It will force the cleanup of listeners log independently by the age
      -dryrun                   It will show the purge commands w/o execute them
      -automigrate              It will run the adrci schema migrate commands in case of DIA-49803
      -h                        Display this help and exit

Example:
       purgeLogs
       purgeLogs -days 20
       purgeLogs -orcl 50
       purgeLogs -orcl 50 -aud -lsnr
       purgeLogs -tfa  50
       purgeLogs -osw  20 -oda 10
       purgeLogs -orcl 20 -osw 20 -oda 10
       purgeLogs -orcl 20 -osw 20 -oda 10 -extra /tmp:10,/var/log:20
```

具体效果测试： 环境，rac19c
``` shell
[root@rac19c soft]# ./purgeLogs -days 20
