安装PSU，有可能会导致实例无法启动
最近某次进行压力测试时，需要安装最新的PSU补丁，现场的同事安装完PSU补丁后，结果数据库集群的其中一个实例无法启动。以下为远程处理的过程，简要记录之。
1、查看集群当前状态：
[root@nodedb01 ~]# crsctl status resource -t
--------------------------------------------------------------------------------
NAME TARGET STATE SERVER STATE_DETAILS
--------------------------------------------------------------------------------

ora.test.db
1 ONLINE OFFLINE Instance Shutdown
2 ONLINE ONLINE nodedb02 Open
可见，整个集群状态都是正常的，仅仅是节点1的数据库实例异常，无法启动。
2、尝试手动启动数据库实例，但查看alert日志：
SQL> startup
ORA-03113: end-of-file on communication channel
SQL>
手动启动实例时，报3113错误，同时数据库的alert日志提示：
********************************************************************
LICENSE_MAX_SESSION = 0
LICENSE_SESSIONS_WARNING = 0
Initial number of CPU is 96
Number of processor cores in the system is 48
Number of processor sockets in the system is 2
alert日志中只有这些信息，启动数据库实例的操作就已经失败。这说明还没有开始读取spfile文件就已经出故障了。
3、检查节点1的补丁信息：
[oracle@nodedb01 ~]$ opatch lsinventory

OPatch succeeded.
[oracle@nodedb01 ~]$
与正常的节点2对比发现，节点1的补丁不完整，只是显示了一部分补丁信息。
4、非常怀疑是补丁安装异常，接着检查了oracle二进制文件的权限：
[oracle@nodedb01 ~]$ cd $ORACLE_HOME/bin
[oracle@nodedb01 bin]$ ll oracle
-rwsr-s--x 1 oracle oinstall 239885712 Sep 6 17:54 oracle
[oracle@nodedb01 bin]$
oracle二进制文件的属组竟然为oinstall。 至此，故障的原因基本已经找到。
5、手动修改属组：
[root@nodedb01 etc]# su - grid
Last login: Fri Sep 6 17:57:38 CST 2019
[grid@nodedb01 ~]$ echo $ORACLE_HOME
/u01/app/11.2.0/grid
[grid@nodedb01 ~]$ /u01/app/11.2.0/grid/bin/setasmgidwrap -o /u01/app/oracle/product/11.2.0/db_1/bin/oracle
[grid@nodedb01 ~]$ exit
6、再次检查补丁情况：
[root@nodedb01 etc]# su - oracle
