清理.patch_storage目錄

某天突然接到告警說oracle目錄使用率高，經過檢查發現.patch_storage占了大約40G的空間。
.patch_storage的作用？
每次在打補丁的時候，會對庫文件和模塊做一些改變；變動之前，opatch會在$ORACLE_HOME/.patch_storage/<patch-id_timestamp> 目錄中創建一個snapshot。有時候會出現需要回滾補丁的時候，這個目錄下面會有一個restore.sh腳本，這個腳本可以remove之前做過的changes。
目錄結構：
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 17592127_Jan_8_2014_23_02_20
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 13343438_Dec_28_2011_01_17_39
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 13923374_Jun_14_2012_23_16_11
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 13696216_Apr_8_2012_21_52_22
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 14727310_Dec_31_2012_01_47_37
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 14275605_Oct_3_2012_23_27_54
drwxr-xr-x    4 oracle   oinstall        256 Nov 08 2016 16056266_Mar_13_2013_05_49_56
其中一個目錄內的文件：
oracle/app/oracle/product/11.2.0/db_1/.patch_storage/17586955_Jun_16_2015_10_26_31$ ls -lrt
total 8
drwxr-xr-x    4 oracle   oinstall        256 Jan 10 23:30 original_patch
drwxr-xr-x    3 oracle   oinstall        256 Jan 10 23:30 files
-rwx--x---    1 oracle   oinstall       1533 Jan 10 23:30 rollback.sh

這也就是說，打補丁的時候是需要一定的磁盤空間的。不然這個copy的過程不能完成。理論上，一次補丁的最大所需空間為1.8G，但是實際上是會小于這個數值的，一般oracle目錄也不會就剩下這么點空間，所以不用太過于關注。

下面是清理過程：

[grid@byo87632:/oracle/app/product/grid]du -sg .patch_storage

從40多G清理到20多G。
