场景：
在对Oracle安装补丁后，会发现OS上被占用了大量的空间，本文档清理Opatch过程中的一些文件，释放空间
参考文档：
Can You Delete $ORACLE_HOME/.patch_storage Directory ? (Doc ID 403218.1)
How To Avoid Disk Full Issues Because OPatch Backups Take Big Amount Of Disk Space. (Doc ID 550522.1)
-- 查看$ORACLE_HOME下的隐藏文件夹.patch_storage。 可以看到之前的补丁过程，产生的一些文件。这些文件主要用于rollback补丁，如果不需要，可以清除，以释放空间。

[oracle@19ctest .patch_storage]$ -- opatch clean的帮助，该命令清除.patch_storage directory文件夹下的'restore.sh,make.txt' files and 'scratch,backup'
[oracle@19ctest ~]$ opatch util cleanup -help
Oracle Interim Patch Installer version 12.2.0.1.41
Copyright (c) 2024, Oracle Corporation. All rights reserved.
DESCRIPTION
This utility cleans up 'restore.sh,make.txt' files and 'scratch,backup'
directories of the.patch_storage directory of Oracle Home.If -ps option is used,
then, it cleans the above specified areas only for that patch, else for all
patches under ORACLE_HOME/.patch_storage. You will be still able to
rollback patches after this cleanup.
SYNTAX
opatch util cleanup [-invPtrLoc <Path to oraInst.loc> ]
[-jre <LOC> ] [-oh <ORACLE_HOME> ]
[-silent] [-report]
[-ps <patch ID with time stamp>, this will
be located under ORACLE_HOME/.patch_storage/]
OPTIONS
-invPtrLoc
Used to locate the oraInst.loc file. Needed when the
installation used the -invPtrLoc flag. This should be
the path to the oraInst.loc file.
-jre
This option tells OPatch to use JRE (java) from the
specified location instead of the default location
under Oracle Home. Both -jdk and -jre options cannot
be specified together. OPatch will display error in
that case.
-oh
The oracle home to work on. This takes precedence over
the environment variable ORACLE_HOME.
-ps
This option is used to specify the Patch ID with timestamp.
This Patch ID with timestamp should be the same as in
.patch_storage directory.
A directory by this name will be present under
ORACLE_HOME/.patch_storage. If this directory is specified
and is valid, then the contents specified in the description
will be cleaned up only for this patch. Otherwise, all patch
related directories will be acted upon by this utility.
-silent
In silent mode, the cleanup always takes place.
-report
Prints the operations without actually executing them.
OPatch succeeded.

SYS@cdbtest SQL> -- 也可以手工清除，官网上对于手工清除，是这样说明的
Additionally, further cleanup of the $ORACLE_HOME/.patch_storage is possible if there are directories from patches applied to previous versions. This can be done manually as follows:
1. run command:
$ opatch lsinventory
2. Remove all the sub-directories from $ORACLE_HOME/.patch_storage that are not present in the list of installed patches. Directory names would be prefaced with the patchid for example:
13343438_<timestamp>
example to find sub-directories : $ opatch lsinventory | grep -E "(^Patch.*applied)|(^Sub-patch)"
Note: List of patches include the sub patches of install Bundle patches, PSU, GI PSU. Hence you should NOT remove the sub patch folders.
[oracle@19ctest ~]$ opatch lsinventory | grep -E "(^Patch.*applied)|(^Sub-patch)"
