2.升级OPatch,两边都需要升级

升级oracle用户OPatch
[oracle@rac01 32545013]$ cd $ORACLE_HOME/OPatch/
[oracle@rac01 OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.17

OPatch succeeded.
[oracle@rac01 32545013]$ cd $ORACLE_HOME
[oracle@rac01 dbhome_1]$ mv OPatch/ OPatchbak 
[oracle@rac01 dbhome_1]$ unzip /tmp/p6880880_190000_Linux-x86-64.zip -d $ORACLE_HOME
[oracle@rac01 OPatch]$ cd /u01/app/oracle/product/19.3.0/db_1/OPatch
[oracle@rac01 OPatch]$ ./opatch version
OPatch Version: 12.2.0.1.27

OPatch succeeded.

升级grid用户OPatch
[root@rac01 grid]# cd /u01/app/19.3.0/grid
[root@rac01 grid]# mv OPatch OPatchbak
[root@rac01 grid]# unzip /tmp/p6880880_190000_Linux-x86-64.zip
[root@rac01 grid]# chown -R grid.oinstall OPatch
[root@rac01 grid]# cd OPatch
[root@rac01 OPatch]# ./opatch version
OPatch Version: 12.2.0.1.27

OPatch succeeded.

3.验证Oracle Inventory的有效性

[grid@rac01 ~]$ $ORACLE_HOME/OPatch/opatch lsinventory -detail -oh $ORACLE_HOME
[oracle@rac01 ~]$ $ORACLE_HOME/OPatch/opatch lsinventory -detail -oh $ORACLE_HOME

4.查看19.12 RU包

p32895426_190000_Linux-x86-64.zip为grid的升级包
p32904851_190000_Linux-x86-64.zip为oracle的升级包
[root@rac01 tmp]# chown -R grid.oinstall 32895426
[root@rac02 tmp]# chown -R grid.oinstall 32895426

5.检查Patch 是否冲突

6.安装前分析

在analyze期间，有一个错误，提示没有fuser命令，所以需要安装psmisc补丁包。
[root@rac01 grid]# yum install -y psmisc
[root@rac01 ~]# /u01/app/19.3.0/grid/OPatch/opatchauto apply /tmp/32895426/ -analyze
