可以通过Patch Manager patchmgr, 存在一个cleanup 选项 ，该选项将清理该Cell节点上所有的Patch文件和临时文件。如果对cell节点打patch失败并没有移除/root/_patch_hctap_的情况。
实际上它会移除的文件包括以下：
/opt/oracle.cellos/DISABLE_HARDWARE_FIRMWARE_CHECKS
/root/_patch_hctap_
/root/dostep.sh
/root/.patch_timeouts
/root/.griddisks_to_activate_if_patch_failed
/tmp/_EXA_AXE_*
/root/_EXA_AXE_*
/opt/oracle.cellos/patch/history/stat
/opt/oracle.cellos/patch/bin/patchstat.sh
$pwd
/root
$du -sh *
4.0K 00
8.0K backup-node.bash
8.0K DoRdsPing.sh
68K dostep.sh
1.6G _patch_hctap_
一般建议在Cleanup之前收集仍需要的日志。
一个典型的打Cell Patch的流程如下：
1. Download any workarounds / help
2. Check the prerequisites:
./patchmgr -cells cell_group
-patch_check_prereq [-rolling]
3. Apply and monitor the patch
./patchmgr -cells cell_group –patch [-rolling]
4. Verify the Patch Succeeded
Executing ‘imageinfo’
Verifying patch logfiles
Check validations.log
Executing CheckHWnFWProfile
5. Cleanup: ./patchmgr -cells cell_group -cleanup
如果要重新打一个失败的Patch， 则也可以 先运行./patchmgr -cells cell_group -cleanup， 之后再patchmgr -patch
