清理.patch_storage目录-创新互联
某天突然接到告警说oracle目录使用率高，经过检查发现.patch_storage占了大约40G的空间。
.patch_storage的作用？
每次在打补丁的时候，会对库文件和模块做一些改变；变动之前，opatch会在$ORACLE_HOME/.patch_storage/ 目录中创建一个snapshot。有时候会出现需要回滚补丁的时候，这个目录下面会有一个restore.sh脚本，这个脚本可以remove之前做过的changes。
目录结构：
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 17592127_Jan_8_2014_23_02_20
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 13343438_Dec_28_2011_01_17_39
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 13923374_Jun_14_2012_23_16_11
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 13696216_Apr_8_2012_21_52_22
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 14727310_Dec_31_2012_01_47_37
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 14275605_Oct_3_2012_23_27_54
drwxr-xr-x 4 oracle oinstall 256 Nov 08 2016 16056266_Mar_13_2013_05_49_56
其中一个目录内的文件：
oracle/app/oracle/product/11.2.0/db_1/.patch_storage/17586955_Jun_16_2015_10_26_31$ 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
这也就是说，打补丁的时候是需要一定的磁盘空间的。不然这个copy的过程不能完成。理论上，一次补丁的大所需空间为1.8G，但是实际上是会小于这个数值的，一般oracle目录也不会就剩下这么点空间，所以不用太过于关注。
