NApply restored the home. Please check your ORACLE_HOME to make sure:
- files are restored properly.
- binaries are re-linked correctly.
(use restore.[sh,bat] and make.txt (Unix only) as a reference. They are located under
"/oracle/app/11.2.0.4/grid/.patch_storage/NApply/2019-05-30_08-48-06AM"
根据错误提示，显示该内容需要软件安装用户进行，猜测应该涉及用户相关问题，通过查询MOS信息获取到该问题在2018年10月GI PSU上，由于报错相关信息跟MOS是否吻合，同时使用root用户验证$USER信息和MOS一致，采取MOS提供解决方式尝试重新安装，安装成功。
[oracle@icdb1:/]#su grid -c "echo $USER"
root
根据MOS提示在安装补丁之前配置用户环境变量
# export USER=
# echo $USER
#
在安装grid和Oracle补丁时需使用不同的USER进行安装,否则容易引起补丁安装失败。该问题已在AIX 71和AIX 72上出现。
