本文记录了一次12C Oracle数据库补丁升级过程中遇到的问题及解决方法。由于错误的文件夹权限设置，导致节点宕机，出现CRS-6760错误。解决方案包括调整文件权限、解锁相关文件并执行特定命令，最终恢复集群和节点正常运行。

最近需要配合某厂商开展12C 的补丁升级工作，升级过程中由于操作人员的误操作导致了节点宕机。特在此进行记录。

主机名	IP地址	DB&GI版本	OS版本	补丁集
Oracle	192.168.56.101	12.2.0.1.0	Oracle Linux 7.3	27674384
Hadoop1	192.168.56.102	12.2.0.1.0	Oracle Linux 7.3	27674384
Hadoop2	192.168.56.103	12.2.0.1.0	Oracle Linux 7.3	27674384

首先我们看下我们的节点按照官方的补丁安装文档，按照后的情况：

12C的补丁升级很简单，主要步骤如下：

1、下载补丁，需要metalink账号

https://updates.oracle.com/Orion/Services/download/p27468969_122010_Linux-x86-64.zip?aru=22096835&patch_file=p27468969_122010_Linux-x86-64.zip

2、使用grid用户解压缩补丁，解压完以后权限如下，这里千万注意解压后文件夹的权限，要注意解压的文件夹属主必须是grid。

[grid@hadoop1 patch]$ ls -l
total 1288616
drwxr-x---. 8 grid oinstall       4096 Apr  9 03:25 27468969
drwxrwxrwx. 8 grid oinstall       4096 Apr  9 03:25 27468969_bak
-rw-r--r--. 1 grid oinstall 1222109132 Jun  5 01:51 p27468969_122010_Linux-x86-64.zip
-rw-r--r--. 1 grid oinstall   97422646 Jun  5 02:59 p6880880_122010_Linux-x86-64.zip

3、检查是否存在冲突

---grid用户下
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/27674384
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/27464465
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/27458609
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/26839277
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/27144050
---oracle 用户下
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/27674384
$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -phBaseDir /u01/patch/27468969/27464465

以上全部PASS后可以进行补丁更新

4、使用root在线更新补丁

[root@hadoop1 patch]# echo $ORACLE_HOME
/oracle/app/grid/grid_home
[root@hadoop1 patch]# opatchauto apply /u01/patch/27468969
bash: opatchauto: command not found...
[root@hadoop1 patch]# $ORACLE_HOME/OPatch/opatchauto apply /u01/patch/27468969
