Oracle 12c补丁安装过程参考补丁文档，以下是大致过程。
1. 更新OPatch
2. 创建OCM应答文件（每个节点）
$ORACLE_HOME/OPatch/ocm/bin/emocmrsp -no_banner -output /u01/ocm/file.rsp
chmod 775 /u01/ocm/file.rsp
3.
cat /tmp/patch_list_gihome.txt
/u01/stage/22899531/21436941
/u01/stage/22899531/22502518
/u01/stage/22899531/23006522
/u01/stage/22899531/22806133
$ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_gihome.txt
cat /tmp/patch_list_dbhome.txt
/u01/stage/22899531/23006522
/u01/stage/22899531/22806133
$ORACLE_HOME/OPatch/opatch prereq CheckSystemSpace -phBaseFile /tmp/patch_list_dbhome.txt
4. 运行安装
