18c rac centos 7.1上安装2020年10月份psu补丁，遇到 can't locate cwd.pm 报错。
正常情况下30分钟就能把gi、db补丁都打上了。
[root@db1 31748523]# /u01/app/18.3/grid/opatch/opatchauto apply /soft/31748523 -oh /u01/app/18.3/grid

解决参考1：
[root@pw ~]# find / -name "cwd.pm"
/usr/lib64/perl5/vendor_perl/cwd.pm
/oracle/oracle/product/db12c/perl/lib/5.22.0/x86_64-linux-thread-multi/cwd.pm
/oracle/12.2/product/grid12c/perl/lib/5.22.0/x86_64-linux-thread-multi/cwd.pm
# export perl5lib=/oracle/12.2/product/grid12c/perl/lib/5.22.0/x86_64-linux-thread-multi/

解决参考2：
there could be a problem with the 'perl5lib' environment variable.
>>> dont see this error in node2 though <<<
check the value of 'perl5lib' and compare against node 2.
set the 'perl5lib' as appropriate so as to access the lib 'strict.pm' and ensure the 'path' variable is able to reach this. note that this is found under both perl5 and gi home.
for example -
ls -l /usr/share/perl5/strict.pm
ls -l //perl/lib//strict.pm
export perl5lib=//perl/lib/:/usr/share/perl5/
export path=$path://perl/lib/:/usr/share/perl5/

安装完毕后：

opatch succeeded.
应该是路径问题，一开始看了一下的确没有这个cwd.pm文件，创建目录，从/u01下搜了一个拷贝一个过去，还是不行。上mos上直接搜不到，百度搜了几个也不合适，还是科学上网了一下，找到上述两个方案，都是一个意思设置perl5lib 这个环境变量(通常是grid用户的$oracle_home/perl/lib/5.22.0/x86_64-linux-thread-multi/)再打补丁，这次差点被百度耽误了。
给主人留下些什么吧！~~
