1.下载补丁包
    2.解压补丁包到oinstall 的账户组的文件目录

    1. su  - oracle
    2. mkdir /u01/app/patch
    3. unzip p28553832_183000OCWRU_Linux-x86-64.zip -d /u01/app/patch/
    4.  chown -R oracle:oinstall /u01/app/patch

    3.一次性补丁冲突检测与解决
    grid 和racdb同时验证

    1. GRID_HOME / OPatch / opatchauto apply <UNZIPPED_PATCH_LOCATION> / 28553832 -analyze;#修补验证
    3. GRID_HOME/OPatch/opatchauto rollback <UNZIPPED_PATCH_LOCATION>/28553832 -analyze;#回滚验证
    4. ---------------------------------
    5. su - root 
    6. cd /u01/app/18.0.0.0/grid/OPatch/
    7. ./opatchauto apply /u01/app/patch/28553832  -analyze;

    4.验证oracle 清单

    1. su - grid
    2. cd /u01/app/18.0.0.0/grid/OPatch/
    3. ./opatch lsinventory  -oh /u01/app/18.0.0.0/grid
    4. su  - oracle
    5. cd  /u01/app/oracle/product/18.0.0.0/dbhome_1/OPatch
    6. ./opatch lsinventory -oh /u01/app/oracle/product/18.0.0.0/dbhome_1

    5.创建ocm响应文件
    注意：此操作12.2.0.1.5 和11.2.0.3.14 之后的版本不在需要 ocm response file

    1. su  - grid
    2. <ORACLE_HOME> / OPatch / ocm / bin / emocmrsp

    6.补丁应用（集群环境可以单节点停机升级，不用全部停，后续每个节点执行）

    1. opatchauto apply <UNZIPPED_PATCH_LOCATION>/28553832 -ocmrf <ocm response file>
    2. ./opatchauto apply /u01/app/patch/28553832
