$ORACLE_HOME为oracle软件安装目录(/oracle/app/product/12.2.0/db_1)$GRID_HOME为grid安装目录(/oracle/grid/crs_1)<UNZIPPED_PATCH_LOCATION>为psu安装包解压路径，本次实验改目录为/soft一、解压opatch工具1.1 root用户修改属组# chown grid:oinstall p6880880_122010_Linux-x86-64.zip1.2 Grid用户双节点执行：$ unzip p6880880_122010_Linux-x86-64.zip -d $ORACLE_HOME1.3 root用户修改属组# chown oracle:oinstall p6880880_122010_Linux-x86-64.zip1.4 Oracle用户双节点执行：$ unzip p6880880_122010_Linux-x86-64.zip -d $ORACLE_HOME查看opatch当前版本[oracle@s1-11g OPatch]$ opatch versionOPatch Version: 12.2.0.1.25OPatch succeeded.二、解压补丁包在双节点执行（grid或oracle用户都可以）$ cd /soft$ unzip p31750108_190000_Linux-x86-64.zip三、安装过程检查readme文件：31750108Patch Number Description Applicable Homes31771877 Database Release Update 19.9.0.0.201020 Only DB Home for non-Oracle RAC setup.
