　　一、OPatch Conflict Check

As the Grid home user:

复制代码

% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36912597

% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36917416

% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36917397

% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36940756

% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36758186

For Oracle home, as home user:

复制代码

% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36912597
% $ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir <UNZIPPED_PATCH_LOCATION>/36916690/36917416

二、OPatch System Space Check

- For Grid Infrastructure home, as home user:
  1. Create file /tmp/patch_list_gihome.txt with the following content:
    复制代码
```
% cat /tmp/patch_list_gihome.txt

<UNZIPPED_PATCH_LOCATION>/36916690/36912597
<UNZIPPED_PATCH_LOCATION>/36916690/36917416
<UNZIPPED_PATCH_LOCATION>/36916690/36917397
<UNZIPPED_PATCH_LOCATION>/36916690/36940756
<UNZIPPED_PATCH_LOCATION>/36916690/36758186
```
    <class="infoboxnote">
    
    Note:
    
    For HP-UX Itanium and Linux on IBM System z platforms, the last two rows in the previous example should not be added to the patch_list_gihome.txt file.
  2. Run the OPatch command to check if enough free space is available in the Grid Infrastructure home:
    复制代码
```
% $ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_gihome.txt
```
- For Oracle home, as home user:
  1. Create file /tmp/patch_list_dbhome.txt with the following content:
    复制代码
```
% cat /tmp/patch_list_dbhome.txt
<UNZIPPED_PATCH_LOCATION>/36916690/36912597
<UNZIPPED_PATCH_LOCATION>/36916690/36917416
```
  2. Run OPatch command to check if enough free space is available in the Oracle home:
    复制代码
```
% $ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_dbhome.txt
```

　　三、As root user, execute the following command on each node of the cluster:
